The Sporlan Electronic Refrigeration Controller System (RCS) is a microprocessor-based system designed to precisely control refrigeration evaporators in walk-in coolers and freezers. Its state-of-the-art design accurately controls refrigerant flow by means of a Sporlan Electric Expansion Valve (EEV). By using precision pressure and temperature sensor inputs, the RCS is able to control evaporator temperature more accurately and consistently than mechanical thermostatic expansion valves, says the company.
