HYCOOL - the green refrigerant

Environmental issues such as ozone depletion and global warming have considerably affected the refrigeration and air-conditioning industry over the last 10 years. In 1996 the Montreal Protocol banned the hazardous CFC’s, and from 2010 on HCFC’s were banned.

HYCOOL was developed to provide the market with an environmentally friendly and equally efficient refrigerant for the future.

With a GWP=01, an ODP=02 and being CFC and HCFC free, HYCOOL enables sustainable and, at the same time, reliable and efficient refrigeration processes for demanding applications. A low TEWI3 underlines the excellent environmental profile of HYCOOL as well as the high efficiency of the systems operated with HYCOOL.

HYCOOL is based on potassium formate and a state of the art corrosion inhibitor. Potassium formate is an organic salt that boasts outstanding environmental and application characteristics. Through its low freezing point, its excellent thermodynamic properties, even at low temperatures, and its high environmental profile, potassium formate is the ideal ingredient for cooling fluids in circulating systems.

The corrosion inhibitor used is non-toxic, safe, long-lasting and the reason for HYCOOL’s high material compatibility with the metals and polymers commonly used in cooling and heating systems.

1 Global Warming Potential (GWP): relative measure to calculate the climate impact of a compound in the atmosphere acting as a greenhouse gas. HYCOOL is stable in processes as well as under external conditions.

2 Ozone Depletion Potential (ODP): relative measure of the effect a compound has on the ozone layer. HYCOOL is stable in processes as well as under external conditions.

3 Total Equivalent Warming Impact (TEWI): Parameter to calculate the theoretical contribution to global warming of a cooling system. TEWI measures the direct and indirect global warming impact of the cooling system.

TEWI = (GWP•L•n) + (GWP•m•[1-R]) + (n•E•B)

(L = primary refrigerant leakage each year [kg], n = operating life of the system [years], m = amount of primary refrigerant [kg], R = recovery ratio of the primary refrigerant, E = energy consumption per year [kWh], B = CO2 emission per kWh)
