  • Page 5 2. FEATURES TRUE DUAL CIRCUITS BPHE The true dual BPHE puts the secondary circuit (water) in contact with 2 primary circuits (refrigerant). So even if one primary circuit is shut off, each secondary channel is still in contact with a primary channel. INVERTER COMPRESSOR Inverter compressor is programmed to run at the optimum speed, which is regulated by the input frequency as it can varies according to the heat load requirement.
