The SWEP PITW85AS is designed for heat pumps and chillers from 5 to 80 kW and is optimized for R290 (Propane) and high-pressure refrigerants, e.g., R32 and R454B. The PITW85AS is equipped with SWEP Hypertwain® ancillary port technology for use in reversible systems requiring high performance in both heating and cooling operation. This offers highest efficiency at full and part load conditions in co-current and counter-current flow. Hypertwain® also offers improved freezing resistance and improved refrigerant distribution. And SWEP AsyMatrix™ plate design delivers optimal heat transfer efficiency at low water pressure drop, and keeps refrigerant charge at a minimum.
