The Dometic VARC 48 uses the advanced technology of an Electronic Expansion Valve (EEV). This provides more precise control of superheat across a broad range of conditions with no erratic swings as the valve reacts to changes in temperature and pressure. Using an advanced algorithm, superior heat control is maintained over extreme operating conditions.
Maximise chiller efficiency and reduce electrical load fluctuations with Dometic’s innovative Variable Capacity Chiller (VARC48 208-230 V/50 or 60Hz). At full speed, the VARC48 provides a nominal 4 tons of cooling or heating. It also has the ability to modulate its speed all the way down to 1 ton in order to precisely match demand. Other chillers use a basic all-on or all-off method for water-loop temperature control, continuously starting and stopping which greatly changes the load on the generator. By precisely balancing output to load, the swing in loop water temperature is minimised as well as swings in demand for power from the generator. The VARC48 uses a precision PID (proportional integral derivative) loop control algorithm that modulates the compressor speed and balances chiller output with the required load. The innovative design of plumbing connections improves ease of installation and maintenance. An optional high-resolution colour touchscreen provides a dynamic interface with improved system metrics and control.
