LEVITOR II AIR COOLED CONDENSER
Specifications subject to change without notice.
Benefits and Features
The LEVITOR system addresses refrigerant coil wear
and leaks due to vibration and thermal stress.
Rooftop condensers have to operate in some of the
toughest conditions imaginable. Temperature extremes
result in constant expansion and contraction of refrigerant
tubes as fans cycle and loads vary.
The consequences are costly: rapid tube wear results in
leaks, system breakdown and loss of costly refrigerant.
LEVITOR Coil Design Eliminates Refrigerant Tube Wear
Environmental concerns and spiraling cost of refrigerants have led to
the development of direct drive remote air-cooled condensers with the
LEVITOR coil support system. This innovative design uses dedicated
stainless steel tubes and a unique coil support system to isolate
refrigerant tubes from the unit. Coil support is transferred from the fins
to the stainless tubes and truncated tube plates which ride freely in “C”
channels. Tubes expand and contract without interference. The result,
contact and friction wear are eliminated.
Quiet by Design
LEVITOR coil design does more than just eliminate tube wear. Sound
reduction is an added benefit. Unlike traditional air-cooled condensers,
fan and coil vibration are isolated from the cabinet, so it is not
transmitted to the unit frame and building supports.
Low Sound Quietor Fan
n The “swept-wing” blade design offers lower noise levels at
the same fan speed. For example, the QUIETOR fan blade
on a 575-rpm motor will be much quieter (8 dBA) than the
old 575-rpm fan.
n Lower noise condensers can translate into savings for your
customer by minimizing the need of costly noise barriers.
n Quietor fan not available on 18” models.
Exclusive 3-year Limited Warranty
n We’re so confident about our new suspended coil
design that it is protected by a 3-year limited warranty
on workmanship and material. It gives you extra
protection from premature tube wear. See
www.krack.ingersollrand.com for complete warranty.
Computerized Circuiting
Our computerized coil circuiting program is designed to
minimize the condenser refrigerant charge and maximize
subcooling. Every condenser will be custom circuited to
precisely meet your application needs.
n
Modular Design
Arranged for vertical or horizontal air discharge.
Multi-fan sections compartmented to allow individual fan
cycling while preventing off-fan “windmilling”. Large
clean-out access doors standard.
n
Corrosion Resistant
All models employ mill galvanized steel fan sections and
coil side baffles. Legs are heavy gauge mill galvanized steel.
n
High Efficiency Coil
Copper tubes are mechanically expanded into
corrugated full collared aluminum fins spaced 8, 10
or 12 per inch. Coils are helium leak and pressure
tested with 400 psig. dry air, shipped pressurized
with dry nitrogen.
n Optional fin materials are copper, heresite, electrofin
or polyester coated aluminum. Multi-circuited coils are
available. Liquid subcooling circuits are available.
n
Direct Driven Propeller Fans
n Quiet multi-bladed propeller fans provide uniform air
distribution through the coil. Venturi fan orifices
optimize efficiency.
Weather Resistant Fan Motors

THR Total Heat of Rejection
n Condenser total heat of rejection (BTU/h) is the sum of the evaporator refrigeration effect and the heat
of compression which varies with compressor type and operating conditions.
TABLE 1
THR Calculation Method
n THR = Open Reciprocating Compressor Capacity
(BTU/h) + (2545 x BHP)
n THR = Suction Gas Cooled Hermetic Reciprocating
Compressor Capacity (BTU/h) + (3413 x kW)
EVAPORATOR
TEMP (˚F)
THR Estimated Method
THR may be estimated by multiplying the rated
compressor BTU/h capacity by the compressor
operating condition factor shown in Table 1 or 2.
Multiply result by altitude factor when applicable.

Multi-Circuit Selection
n Condenser coils may be divided into several individual refrigeration circuits or systems; each sized for a specific refrigerant,
THR capacity and TD. Systems are tagged for identification from left to right; facing the connection end. Avoid locating
high TD sections next to low TD sections. Add excess circuits to low TD sections next to High TD sections. Add excess
circuits to outboard sections. Thermal Fantrol fan cycling is recommended with multi-circuited condensers.

Levitor Application
Locate Condensers no closer than their width from walls
or other condensers. Avoid locations near exhaust fans,
plumbing vents, flues or chimneys.
Gravity Liquid Drain Lines should drop from each
outlet as low as possible before headering or running
horizontally. Pitch downhill to receiver.
Parallel Condensers should be the same models resulting
in the same refrigerant side pressure drops. Compressor
discharge lines should have equal pressure drops to each
condenser.
Off-Line Coil Sections will have refrigerant pressures
corresponding to the ambient. Check valves or isolating
valves should be installed in the liquid line drains to
prevent refrigerant migration and receiver pressure loss.
Condenser Charge will approximate 30% of the
maximum flooding charge listed under “Specifications” for
summer design conditions. Low ambient head pressure
controls require an additional charge, which is difficult to
predict with fan cycling and is maximized with holdback.
Liquid Subcooling may be accomplished with a section
of circuits in the coil. Liquid outlet temperature will
approach the entering air temperature by approximately
5°F. Benefit is not economical unless TD is 15°F or
higher.
Receiver Capacity should be sized to store condenser
summer charge, plus the condenser low ambient
allowance, plus the evaporator charge, plus an allowance
for piping and heat reclaim coil charges.
See Installation & Operating instructions for piping,
holdback and fan cycling details.
Compressor Discharge lines should be sized to minimize
pressure drops and maintain oil return gas velocities. Each
connection should be looped to the top of the condenser.

Capacity is compressor suction tons for application between -40°F and +40°F suction at condensing
temperatures between 80°F and 120°F sat.
For multiple or unloading compressor applications, the vertical discharge riser from the compressor
may need to be one size smaller.

Thermal Fantrol-Electronic temperature control
cycles fans in response to entering air temperature.
Set points and differential for each step are
adjustable.
Pressurtrol-Electronic pressure control with single
point pressure transducer cycles fans in response to
condenser pressure. Set points and differential for
each step are adjustable.
Thermal Pressure Fantrol-Electronic temperature
control cycle fans in response to entering air
temperature, except for header end fan(s). Header
end fan(s) are controlled by pressure control.
Variable Speed Control-Header end fan(s) are
controlled with a speed controller in response to
head pressure. Electronic pressure control cycles the
balance of fans.
Fan cycling Sequence-Fans are cycled off
individually or side-by-side in pairs in sequence
from the end opposite the header to the header
end. Header end fans run continuously if
compressors are operating.
Control Panel
Standard weather resistant enclosure is mounted
on the opposite end of the unit when looking at the
headers.
n Control power is 24, 115 or 230 volts. A transformer is
factory installed when required.
n Fan contactor with branch circuit fuse protection.
Each motor or bank of motors protected by fuses.
n For horizontal airflow application, consult factory.
n Disconnect not included, but may be required to
meet local codes.
n
Optional Arrangements
n Fan motor contactor and fuses only.
n Fan motor contactor and fuses only which operate
via a customer specified solid state board. Circuit
board is factory mounted and wired.
n 50/50 split with two fan wide models. Each side is
controlled separately with individual control panels on
each side.
n 50% winter reduction with two fan wide models.
The right side fans are isolated in winter. Fans are
locked out via a relay or switch during shutdown.

Low Ambient Controls (Head Pressure Control System)
Piping Schematic For Winter Control
n Head Pressure Control for systems with air-cooled
condenser is accomplished with two pressure
regulating valves designed specifically for this type
of application. When low ambient conditions are
encountered during winter operation on air-cooled
systems with a resultant drop in condensing
pressure, the Head Pressure control’s purpose is
to hold back enough of the condenser liquid
refrigerant so that some of the condenser surface
is rendered inactive. This reduction of active
condensing surface results in a rise in the
condensing pressure and sufficient liquid line
pressure for normal system operation.
