The DB650 is a highly effective, versatile true dual that is a natural choice for chillers and heat pump applications. Its advantage is its ability to offer full performance at both full and partial load. It is optimized for extreme performance with refrigerants. The product is approved for pressures of up to 49 bar (710 psi), so it can be used with the majority of current high-pressure refrigerants, enabling our customers to use the compressor’s whole envelope. SWEP’s versatile H pressure products enable efficient heat exchange in applications combining small flows and high pressures.
