Image of Variable Capacity ChillerMaximize chiller efficiency and reduce electrical load fluctuations with Dometic's innovative Variable Capacity Chiller (VARC48). At full speed, the VARC48 provides up to four tons of cooling or heating. It also has the ability to modulate its speed all the way down to one ton in order to precisely match demand.

Standard chillers use a basic all-on or all-off method of water-loop temperature control which greatly changes the load on the generator. By precisely balancing output to load, the swing (hysteresis) in loop water temperature is minimized.

The VARC48's Electronic Expansion Valve (EEV) provides more precise control of superheat across a broad range of conditions with no erractic swings as the valve reacts to temperature and pressure changes (no "hunting").
