F-gases Fluorinated gases (‘F-gases’) are man-made gases used in a range of industrial applications. Because they do not damage the atmospheric ozone layer, they are often used as substitutes for ozone-depleting substances. However, F-gases can stay in the atmosphere for centuries and contribute to a global greenhouse effect, with a global warming effect up to 8000 times greater than carbon dioxide (CO2), and their emissions are rising strongly. The three groups of F-gases are hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). HFCs are by far the most relevant F-gases from a climate perspective. F-gases account for 2% of the EU’s overall greenhouse gas emissions, but F-gas emissions have risen by 60% since 1990 in contrast to all other greenhouse gases, which have been reduced. F-gas emissions to be cut by two-thirds by 2030 The European Union is therefore taking regulatory action to control F-gases as part of its policy to combat climate change. A new Regulation, which replaces the first and applies from 1 January 2015, strengthens the existing measures and introduces a number of far-reaching changes. By 2030 it will cut the EU’s F-gas emissions by two-thirds compared with 2014 levels. This represents a fair and cost-efficient contribution by the F-gas sector to the EU’s objective of cutting its overall greenhouse gas emissions by 80-95% of 1990 levels by 2050. The expected cumulative emission savings are 1.5 Gigatonnes of CO2-equivalent by 2030 and 5 Gigatonnes by 2050. The latter number is more than the CO2 produced by a billion return flights from Paris to New York.

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide. A GWP is calculated over a specific time interval, commonly 20, 100 or 500 years. GWP is expressed as a multiplying factor of carbon dioxide value that is standardized equal to GWP=1. In the past, refrigerants artificial category HCFC (HydroChloro-Fluoro-Carbides) were used but, later were banded because they were one of main causes of Ozone layer depletion (high ODP value). Currently mainly used refrigerants as HCFC subsitutes, belong to HFC category (Hydro-Fluoro-Carbides) with ODP=0, but with still strong greenhouse effect (HIgh GWP). Natural refrigerants (R744, R717) and hydrocarbons HC (R290) represent an alternative to HFCs but with several implications and limitations. New chemical refrigerants belonging to HFO category (Hydro-Fluoro-Olefin) like R1234ze/R1234yf offer a good alternative to HFC, offering: • Adaptation to exhisting Chillers Design • Higher Efficiency • Longer life of components • Suitable for all climate zones HFCs ODP=0 GWP 1400÷3500 R410A R407C R404A R134a mid 1990 HCFCs high ODP & GWP R123 R22 CFCs very high ODP & GWP R12 1990 WIDE CAPACITY RANGE STD | 244÷1.226 kW on 25 sizes 2,3,o 4 compressors /HE - high efficiency | 263÷1.042 kW on 18 sizes /SLN - super low noise | 253÷1.004 kW on 18 sizes 200 400 600 chiller only 800 1000 1.200 freecooling available CONTROL FUNCTION (HFO OPTIMIZED) Unit management by integrated web server page (alarms, set points, antisticking function...)

MICROCHANNEL ALUMINIUM COIL Kappa Rev LGW units use this new generation of condensing coil on chiller section as standard. This means: •Extended life cycle •10% overall chiller weight reduction •less air side pressure drop 30% less refrigerant LEAK DETECTION The unit is equipped of a leak detector located in the compressor compartement, with the pump down function that encloses the refrigerant in the condensing coil. R1234ze has been classified on safety group 2 for PED (european standard).
