Digital E-Star HiPerForm EVC Refrigeration Unit

Refrigeration runs through lines connected to tanks. 1-4 per tank. The new Digital E-Star HiPerForm EVC is a perfect match for robotic milking. Its ability to reduce capacity allows small volumes of milk to be cooled immediately, no matter what size of milk cooler you may have. The goal is to cool your milk as quickly as possible and as efficiently as possible, without building ice and without damaging your milk cooling equipment. The new Digital E-Star accomplishes just that. Turn this condensing unit on as soon as milk touches your agitator and the unit will do the rest. 


  • Proprietary electronic subcooling valve and control optimizes the milk cooler evaporator for maximum operating efficiency.
  • Copeland® Scroll compressor is designed to handle the large temperature changes required to cool milk. Scroll technology is more energy efficient and has less moving parts than reciprocating compressors.
  • Condenser subcooling coil ensures subcooled liquid refrigerant for maximum evaporator efficiency.
  • Enhanced condenser heat transfer surface due to enlarged tube-and-fin condenser with rifled tubing results in greater refrigeration capacity and efficiency.
  • Suction line accumulator heat exchanger increases system efficiency and protects compressor during low-load conditions.
  • Single, variable-speed fan with high-efficiency motor maintains an even air flow to increase capacity and efficiency of the compressor.
  • Electrical compartment located in the upper front portion of the unit permits easy access.
  • HiPerForm is available for use with environmentally friendly HFC-507.
  • Screw terminals provide positive electrical connections and reduce compressor failure.
  • CSA/cUS approved for indoor and outdoor use.
  • Oil sight glass and fill port allows simple inspection of compressor oil level and provides an easy method to add or change oil for future refrigerant requirements.
  • Heavy-duty, galvanized three-piece metal cover encloses and protects the unit for safe operation.
  • Rust-resistant brass high- and low-side valves located in front of the unit for easy service access without removing the cover.
  • Quality assured. Meets worldwide standards such as CSA and CE.
