SINGLE-HOUSING ROTARY SCREW COMPRESSOR
The new Frick RSHC 43 Semi-Hermetic Rotary Screw Compressor brings Frick Screw compressor reliability and lower total cost of ownership to your CO2 cascade system. With increasing regulations on HFCs, natural refrigerants, such as carbon dioxide and ammonia, are becoming more common. The Frick RSHC 43 is a motor and screw compressor combined into a single housing. Incorporating the motor and compressor into a single housing reduces cost and eliminates the need for a shaft seal and drive coupling. The compressor has a design pressure of 600 psi and uses the latest Frick technology for high performance screw compressors. The capacity control is with a variable frequency drive (VFD) which operates from 1800 to 7200 rpm. The RSHC 43 can support evaporator temperatures from -40 F to 0 F for various cold storage and process applications.

R-454B REFRIGERANT CHOICE FOR CHILLERS AND HVAC EQUIPMENT
After extensive research, testing and evaluation, Johnson Controls, a global leader for smart, healthy and sustainable buildings, has selected R-454B, a lower global warming potential (GWP) refrigerant, to replace R-410A in its ducted residential and commercial unitary products as well as air-cooled scroll chillers. Systems using the new refrigerant will be available for Johnson Controls, YORK (pictured), Luxaire, Coleman, Champion, TempMaster, Fraser-Johnston, Guardian, Evcon and Quantech branded products in North America, as well as specific international markets where codes are in alignment. This decision was made as the HVAC industry is preparing to phase out high-GWP refrigerants, such as R-410A, which are now being formally addressed by the Environmental Protection Agency (EPA) through the recently passed American Innovation and Manufacturing (AIM) Act. The AIM Act directs the EPA to phase down U.S. hydrofluorocarbon (HFC) production and use by approximately 85% over the next 15 years.
