The efficiency is determined by pumping losses. The closer the outer surface of the inner scroll comes to the inside surface of the outer scroll, the less leakage there will be. This phenomenon is ...

Electronically commutated motor (ECM) pumps, fans, and a scroll compressor work together to enable the Veritus HPWH to operate with a high coefficient of performance (COP), optimize heat transfer, and ...
