The SubAir System - Great Sports Infra
The SubAir System The SubAir aeration and moisture removal system promotes healthier and stronger playing surfaces through moisture content management, subsurface aeration, and root zone temperature control. As a result, SubAir provides optimum aerobic subsurface growing conditions. SubAir is integrated underground with no impact on the design of the golf course. A SubAir Elite vault, housing the blower that provides both vacuum and pressure mode, is connected to the green’s drainage piping network. Elite Vault A Distributed Separator is connected to the green’s drainage network. This patented assembly separates the air from the water so that the air flows to the SubAir vault and the water drains to the outfall. A Dual Valve is used on the end of each outfall to create an air lock. This directs the air through the soil profile so it does not escape through an open ended pipe. The SubAir system applies a vacuum within the subsoil drainage pipe network to increase the rate at which water is moved from the surface and through the soil profile. The management of subsoil moisture also helps with temperature moderation in the entire soil profile. (Above - Dual Valve interior in vacuum mode) In vacuum mode, SubAir routes air to the blower and water to a drainage area for moisture control. SubAir also applies pressure to force air from the subsoil pipes through the soil profile. This patented technology creates air movement that provides aeration while moderating temperature in the root zone. The Distributed Separator and the Dual Valve are components of the SubAir Operation Package . These components are also used to operate the SubAir portable system, the Air Force One. (Above - Dual Valve interior in pressure mode) During pressure mode, the SubAir unit moves air upward through the soil. Distributed Separator www.subairsystems.com | www. turfbreeze.com Dual Valve 1 SubAir’s control system is housed in a standard irrigation satellite and is located away from the green. Once the installation is complete, only the air intake/exhaust ( 9” x 9” ) and vault inspection port are visible. SubAir Control Panel How the SubAir System Operates The best location for the SubAir vault is at the high end of the green. The elevation forces the air to flow uphill to the SubAir unit and allows gravity to drain water down to the outfall. In vacuum mode, air and water are moved downward through the soil into the drainage pipes. Once the air and water enter the pipe, gravity moves the water down to the outfall and the SubAir moves the air to the back of the green and out through the SubAir exhaust. Installation typically takes one day per unit and can be accomplished with minimal disruption of play.

Adding After installation of the SubAir pieces Operation Package, many incrementally, clubs choose to utilize the Air makes putting Force One (SubAir portable together the SubAir system) on their most puzzle easy and affordable. problematic greens. By using the Air Force One and learning how it benefits troubled areas, the next progression is to install an Elite (a SubAir permanent system) on problem greens. The Air Force One is then free to be moved around the course for regular aeration of the remaining greens. As the budget allows, SubAir Elites can be added, two or three each year, to the rest of the golf course. SubAir Project Managers can assist in long range planning and strategy to ensure smooth installation over an extended time period. To install SubAir, the course will need USGA specification greens or California style greens. No matter After installation of the SubAir Operation which SubAir product is chosen, the Package, an Air Force One may be utilized SubAir Operation Package is required to begin an aerification regimen. to connect the drainage system to SubAir. These components can be installed during construction, during renovation projects, or while the course is open for play. Installation does not disrupt play and all the work is performed off the green so it will not interfere with golfers on the course. www.subairsystems.com | www. turfbreeze.com SubAir Project Managers are qualified agronomists with experience in both golf course construction and maintenance. Using topographical maps and coordinating with the golf course architect, project supervisor, irrigation specialist, superintendent, and the local utility company, SubAir provides a comprehensive plan for SubAir can develop a plan for installation the mechanical and electrical to ensure it is performed as quickly as installation of your SubAir system. possible with little disruption to the SubAir provides on-site supervision operation of the course. of the golf course contractor or staff to ensure proper installation and commissioning of your SubAir components. SubAir’s Project Managers also provide consultation with the superintendent to develop an operating program based on environmental conditions (temperature, moisture, etc.) and turf health (root length, root density, thatch accumulation, etc.). After the SubAir system is operational and the operating program has been implemented, SubAir is always available to provide technical and consultative service. Once SubAir becomes an important aspect of your turf management routine, you want to be certain your SubAir units are in top operating condition year round. SubAir offers standard or custom designed service and support contracts tailored to meet the demands put on your SubAir equipment. Whether you have SubAir on one or all greens, SubAir is there providing superior service for a superior product. SubAir Service & Support Packages include annual site visits, technology updates, urgent SubAir Service and Support Packages response, training programs for provide certainty that your SubAir units are course staff, and discounts on in top operating condition year round. additional site visits and parts. 3 The Hydronics System For grass plants to thrive they need certain conditions. An optimum growing environment consists of the proper amount of sun, proper air/water ratios and proper soil temperatures. The Hydronics system can provide heating or cooling to maintain ideal root zone temperatures by pumping warm or cool fluid from the holding tank to the green via a supply pipe. The fluid circulates under the root zone of the green through a network of flexible tubing. The working fluid is then returned to the holding tank. The Hydronics turf temperature control system consists of several important pieces of equipment - a boiler, chiller, chiller pump, green pump, holding tank, temperature and pressure instrumentation, and control enclosure. Each system is skid mounted with tank, controls, Boiler and pump on one Holding Chiller Control skid and Tank Panel the chiller and chiller pump on Green another. Pump The skid mounted Chiller Return & Supply Lines Hydronics Chiller Pump assembly is housed away from the green in a building aesthetically pleasing to the surroundings of the golf course. 4 Greens at Haesley Golf Club, South Korea. This dramatic photo illustrates the operation of SubAir Hydronics and SubAir. SubAir’s Hydronics system is designed to condition and maintain ideal root zone temperatures during warm and cool season operation. Using the Hydronics system along with SubAir will create an air flow through the root zone to evenly distribute the heating or cooling effects of the Hydronic tubing. This even treatment of the playing surface eliminates hot and cold spots in the soil.

AirWave features and options include simultaneously controlling each SubAir system, scheduling SubAir operation time and duration, and optimizing SubAir performance based on sensor readings and user specified target conditions. Add wireless dual layer sensors to your AirWave system to monitor soil temperature, moisture, and salt levels at two separate depths in the soil profile. Sensors can also be installed to monitor tee boxes, fairways, flower beds, or other areas of interest . The data collected by the sensors is transmitted back to the base computer via the SubAir control panel and/or AirWave repeaters. The need for repeaters is determined by course topography and distance. At the base station, real-time data collected by the sensors is used by AirWave to optimize operational parameters. Sensor data (logged at 5 minute intervals) can be viewed on historical data plots to provide a clear picture of the impact of agronomic practices, natural phenomena, and weather events on turf conditions. The AirWave Sensor is installed in the green with a standard cup cutter. Soil data is collected by the sensors and transmitted back to the computer base via the Sub Air Control Panel and AirWave Repeaters. At the base station, the real-time data collected by the sensors is used to optimize the operational parameters of the SubAir System. www.subairsystems.com | www. turfbreeze.com 5 Cog Hill Country Club Chicago, Illinois “Naturally we use SubAir Cog Hill Country Club in Chicago, Illinois when we have heavy rains. includes almost every product SubAir We can use it whenever we need it, but we also have offers in their turf maintenance routine. them running on an intermittent schedule.” There are SubAir systems on 19 greens and Ken Lapp, Superintendent one tee. All are controlled by the AirWave wireless monitoring and control system with AirWave soil sensors on holes number 16 and number 4. In addition, they have four TurfBreeze fans located in areas with poor air circulation. When Cog Hill began its renovation of their Dubsdread Course in 2007, owner Frank Jemsek chose to include SubAir on every green. Superintendent Ken Lapp has been in golf course maintenance for 55 years and has been impressed by the technology he now uses daily to maintain his greens. “Naturally we use SubAir when we have heavy rains. It takes the water right off. Then, when we want to firm up the greens we use it as a tool for that. We can use it whenever we need it, but we also have them running on an intermittent schedule,” explains Lapp. Cog Hill’s SubAir system is controlled by AirWave. “The AirWave has really surprised me. This technology has really helped out. We have AirWave soil sensors on two greens – number 16 and number 4. On these greens I can tell what my moisture level is and the soil temperature. I think it’s a valuable tool and I wouldn’t mind seeing AirWave sensors on all the greens. During the summer, and especially this summer, I was looking at it (AirWave monitoring screens) everyday just to see where we were.” Lapp is also very satisfied with SubAir’s customer service. “The units were put in during the rebuilding of the greens by the golf course construction company under SubAir’s supervision. Before construction began, a SubAir Project Manager laid out all the spots where the vaults would be installed. He has been there to help me learn the best ways to use the system. And with the SubAir Service and Support Package, he comes annually and checks every green and runs tests on everything to make sure there is no trouble at all. SubAir’s customer service has been tremendous!” “I can definitely tell a difference between now and before SubAir was installed,” praises Lapp. “Especially when you get a rain, you turn it on and the water is sucked right out of the greens, gets the players out faster!” Cog Hill has been attracting golfers since 1927. Located in the Des Plaines River Valley 30 miles southwest of Chicago, the Club has four courses including the world famous Dubsdread Course. 6 SubAir Product Specifications Elite Specifications Blower Max.

Solar heat can have a devastating effect on turfgrass. When a green’s subsoil Developed to provide air airflflow on the temperature reaches high levels, surface of golf course greens, turfgrass roots begin to shrink, TurfBreeze is the most respected diminishing the quality of the name in surface aeration. putting surface. Fan use can lower the surface temperature of a green up to 10° Fahrenheit, which in turn, lowers the soil temperature approximately 4° to 6° F. Fan use increases turfgrass transpiration, cooling the plant internally and keeping it healthier overall. As an added benefit, TurfBreeze fans can be used to evaporate excess moisture from heavy morning dew. Although thinning trees works best, fans have shown to improve the quality of shaded greens. TurfBreeze will assist you in planning fan size, quantity, and placement to best suit the needs of your course. TurfBreeze Premium at The Patriot Club, Owasso, Oklahoma “I chose the TurfBreeze Premium Fan based on its efficiency and its lower noise level compared to the bigger 7.5 HP motor. There is no doubt these fans helped us get through the most brutal summer I’ve ever experienced.” Jeremy Dobson, Superintendent, The Patriot Club www.subairsystems.com | www. turfbreeze.com The TurfBreeze Fan TurfBreeze Features The TurfBreeze maintenance free design offers simple installation. Pre-wired fan motors, oscillating motors, and control packages come pre-assembled for easy plug-in installation. Ground poles, fan poles, oscillating assemblies, and power control packages are standard TurfBreeze features. TurfBreeze fans are pre-wired and pre-assembled for easier installation. Fan housings are shipped with oscillating assemblies and linkages installed and fan poles have all electrical controls pre-mounted. In addition, the fan motor, oscillating motor, and control packages are pre-wired with inter-connecting water proof plugs for simple plug-in installation. The power control package, includes a lockable power disconnect, an electronic starter contact for remote use through an irrigation signal, an overload protection circuit, and a manual start/stop switch. TurfBreeze fans are virtually maintenance free. A new synchronized drive system eliminates the need for periodic belt tensioning and sealed pillow block bearings require no re-lubrication. TurfBreeze Premium For situations in which power and sound create special requirements, TurfBreeze offers a Premium model producing maximum cooling with minimal power use and motor noise. The TurfBreeze Premium 5 HP Fan has the efficiency of a 7.5 HP, the quietness of a 3 HP, and durable steel construction. The TurfBreeze Premium offers courses a “green” option by consuming less power (see power chart on page 9), yet providing the same great results you’ve come to expect from a TurfBreeze Fan. 7 Carolina Golf Club TurfBreeze Planning Size Fans are rated in CFM (cubic feet per minute) at a specific static pressure. Similar to sprinkler heads, fan size must provide adequate energy to offer sufficient velocity at the furthest point from the fan. Quantity Charlotte, North Carolina Fans can be discreetly hidden in tree lines and silhouetted against a background. The general rule of thumb is one fan per green. One large fan always works better than two or more smaller fans. Even for deeply pocketed greens, one fan will suffice, but you may need to choose a fan with a higher CFM to provide adequate air movement over the entire surface. Placement Fans can be discreetly hidden in tree lines and silhouetted against a background. Even though fans are usually quieter than a homeowner’s air conditioning system, it is best to keep fans as far as possible from patios and porches as the predominant fan “sound path” is from the inlet to outlet. Set the oscillation range as short as possible to achieve the best coverage. If the oscillator is set at half of the maximum range, twice the amount of air reaches the green. Optimally, a fan should be positioned horizontal to the green with a 30° cone of air catching the edge of the green closest to the fan. Placing a TurfBreeze Order With the high demand during warm weather, the best time to order your TurfBreeze product is during fall, winter, or early spring. TurfBreeze encourages early orders so that fans can be delivered, properly installed and ready to operate prior to the arrival of hot, humid weather. 8 “I can’t find the words to describe the great customer service. As soon as you place an order the ball is rolling. The entire team has been tremendous to work with. We’ve had no issues at all!” Matthew Warton, Superintendent Matthew Wharton, Superintendent at Carolina Golf Club in Charlotte, North Carolina, became interested in TurfBreeze fans simply because of their size. “I saw some TurfBreeze fans on another course in Charlotte and was impressed by how big they were,” explains Wharton. In 2008, Carolina Golf Club underwent a total restoration. Because of the new course configuration, Wharton made advance arrangements for the purchase and installation of two TurfBreeze fans. A TurfBreeze representative visited the course and determined locations for the best performance and minimal visibility. “We completed the grow-in and the fans helped tremendously.” The wet summer of 2009 forced Wharton to acquire one additional fan for Carolina Golf Club. “I had issues with our first green that year because of numerous severe thunderstorms. It was definitely our worst putting surface and we decided a fan would solve any similar issues in future years.” Again Matthew contacted his TurfBreeze representative and together they determined the location for maximum performance. The fan was installed just prior to the summer of 2010. The summer of 2010 put Wharton’s fans to the test and before its end, Carolina Golf Club would purchase five more TurfBreeze fans. “The combination of heat and humidity, the consistency of it with no relief at night led to the severe decline of five greens. I had fans on three greens and by mid-July they were the three best conditioned putting surfaces on the course. I went to the Board and received approval to buy five more fans. We were able to quickly get four of them installed and operational in less than two weeks. I was able to see visible turf improvement in less than a week. Unfortunately we had issues getting power to the fifth location and were not able to get the final fan operational until mid-September. The immediate improvement of the four greens while the fifth continued to suffer for another six weeks put the final stamp of approval on the importance of our fans.” Wharton continues to illustrate how much he has come to rely on his TurfBreeze fans. “This year the weather was so bad even the putting greens located in ideal growing environments declined to a point where the greens with fans looked better. Our number 16 green is in a less than ideal location and this year it was the best conditioned putting surface on the course. Plus our number one green went from being the worst putting surface in 2009 to one of the best in 2010.” The Carolina Golf Club is located in Charlotte, NC. Matthew Wharton, a native of Castlewood, Virginia, is a graduate of Virginia Tech. He has been the Golf Course Superintendent at Carolina Golf Club since 2005. 803.641.6663 | 866.641.6663 TurfBreeze Product Specifications Model Numbers All model numbers begin with the letter “TB” for TurfBreeze.

Our course has a lot of mature trees which limits air flow creating micro-climates for several of our greens. They seem to really hold on to the heat. Poor turf density, along with being the first to show signs of disease, was the norm for these greens versus the others with adequate air flow. Historically, they would always recover the worst – from ball-mark damage, from foot traffic, and ultimately from summer stress. After putting the fan on the green, we cut down our water usage, we cut down our fungicide usage, and, we cut down our stress level. Ultimately it was just a win-win and our members noticed. On one green which was a par 3, it was not uncommon for balls to plug on the green during the summer. But after we were able to install the fan, the green was firmer. We were able to manage our water a lot better by installing the fan. We didn’t have the plugging effect like we did before.” Kroeze likes the flexibility of being able to manipulate his fan usage according to the weather forecast. He sets simple timers to turn the fans on and off, usually running them between 9-10 hours per day. “I tend to turn them on when I know the temperature is rising. It will be 103-106 (degrees) on an average day from mid June to early September. If the humidity is really bad, then I will run them during the night.” For the first time this year, Kroeze plans to leave his fans up during the winter to evaluate getting the golfers out earlier on mornings when frost is present. “The TurfBreeze customer service team does a great job of getting me what I need ASAP – anything from order acknowledgements to schematics and,” laughs Kroeze, “their Southern charm is the icing on the cake!” The Kings River Golf and Country Club is located in Kingsburg, California. The club is a private, member-owned 18- hole championship golf course. It opened in 1955 and was designed by Bert Stamps and Neal Meagher. 9 Cedar Ridge Golf Club SubAir and TurfBreeze Adding Pieces to the Puzzle Broken Arrow, Oklahoma Mike Wooten, Superintendent at Cedar Ridge Golf Course in Broken Arrow, OK learned about TurfBreeze from a fellow superintendent in his area. Wooten was already the owner of 14 fans, but none were TurfBreeze. He now owns one TurfBreeze fan. “The TurfBreeze fan seems to push more air. It seems like the TurfBreeze fan reaches out farther.” Mike Wooten, Superintendent Wooten has seen a comparison between his fans. “The TurfBreeze fan seems to push more air. It seems like the TurfBreeze fan reaches out farther. It really seems like it puts out more (air).” Wooten explains, “A TurfBreeze representative came out and we talked about the fans themselves and then we talked about the electrical wire sizing. He also set the locations. Six of our previously purchased fans were made by a local person and TurfBreeze was also able to retro-fit these old fans with oscillators.” “We are looking at new placements closer to the greens because fans have become much more accepted by the members. I believe you could place the fan right in the middle of the green and have it oscillate 360 degrees and they would accept it now,” jokes Wooten. The two processes - SubAir and TurfBreeze - are different, and yet both beneficial in their own way. SubAir is used primarily for good gas exchange in the soil and to create optimum air/water ratios in the soil profile. TurfBreeze fans are designed to improve surface conditions. The two processes together help provide the best possible conditions for growth and survival of a plant species in very challenging conditions. Clubs using both SubAir and TurfBreeze are proactive in their approach, using different tools to extend the life of the greens and ensure that not only do they survive, but they are the championship caliber that their members expect. “August is our worst month for bentgrass in Dallas with the roots shrinking up to almost nothing. The putting green is our worst green because it’s small and gets a lot of traffic. SubAir has been in use the last two summers and it has been one of our better greens since. Every summer before the SubAir was installed we would close the green for a couple of weeks each summer, but not anymore. It’s also important to note that we installed TurfBreeze fans on this green at the same time.“ Kevin Carpenter, Superintendent, The Northwood Club, Dallas, Texas Wooten discusses how he uses fans in his turf maintenance routine. “We set them up usually the third week of June following the club’s member guest tournament and take the fans in for the winter, right after Labor Day. If we can ever get them out earlier we will. We run them all day – 24 hours per day. Ninety-nine percent of the time, once they get turned on, they don’t get turned off until we bring them in.” Wooten adds, “The fan works great – no problems. It just seems like the TurfBreeze does more. All the guys that have called me about fans, I’ve told them, they ought to be dealing with TurfBreeze!” The golf course at Cedar Ridge Country Club was designed by Joe Finger in 1967 and is described as one of the country’s finest. Cedar Ridge has hosted many outstanding national and regional tournaments. 10 August 2007 - The Northwood Club root sample prior to SubAir and TurfBreeze installation.
