EV3S Controllers

Controllers for
  • Refrigerated display units
  • Ice-cream and pastry counters
  • In split version
EV3S is a range of elegantly designed controllers for the management of refrigerated display units, ice-cream and pastry counters.
They are available in split version; the user interface comprises a large custom display (with decimal point and function icons), four touch keys, and has a guaranteed IP65 protection grade, for easy cleaning.

The controllers use an electromechanical relay, rated load 30A @ 250VAC, for direct control of high-power compressors, thus avoiding the use of contactors. They can also be connected directly to the load.

They can protect the compressor (causing it to switch off) if the condenser temperature is outside an allowed range; they have the adaptive management of the defrost function and can implement energy-saving strategies.

Installation is by panel, with snap-in brackets.
