The Superheat control provides true pressure/temperature superheat control via EEV utilizing Sporlan’s unique control algorithms, while the subcool control replaces mechanical subcooling that combines liquid temperature control and minimum superheat control. The temperature and pressure controls allow precise control of air temperature and pressure using electric valves (SDR and CDS).

The Kelvin II controller line boasts both integrated and remote display options, Modbus® (via RS485) networking, Auto PID and simple setup and operation.
