  1. iColdand RCSElectronic Refrigeration ControlSystems

  2. iCold is the Complete Package

  3. RCS and iCold • Features and Benefits – Both • Integrated digital temperature control • Conventional and advanced defrost routines • True Pressure/Temperature Superheat • Controls all Sporlan valves (Bipolar and Unipolar) • RS-485 communication port • Pluggable connectors for easy wiring • Controllers supplied with SNAP-TRAK for quick installation • Compressor protection algorithms with FloodGuard™ • Onboard user interface with 3 digit alphanumeric display • iCold • Complete package ready to control out of the box • Watertight NEMA 4 enclosure

  4. Set Points & Process Measurements • Control Settings • Target superheat • Min and max valve capacity • Discharge air Cut-in / Cut-out temperatures • MOP • PID • Cycle time • Refrigerant • Defrost schedule / settings • Process Measurements • Suction pressure • Calculated superheat • Valve capacity • Evaporator inlet / outlet temperatures • Fixture temperature • Auxiliary input • Defrost termination temperature

  5. RCS is Menu Driven

  6. Initial Applications Convenience Stores Fast Food Outlets Restaurants Institutional Kitchens Sports Arenas

  7. RCS System Elements • Electronic controller • Electronic expansion valve • Bipolar and Unipolar stepper • Pressure transducer • Temperature sensors • User interface options • On-board display • Remote display/interface ( available 1Q2008) • PC (Windows software) • Modem (optional)

  8. RCS System Hardware Sporlan SEI shown, model ESX, SER or SEH can be used
