  • Chillers of the EF series have a built-in free-cooling circuit, which makes it possible to use the low ambient temperature in winter to cool the heating medium. This results in significant savings in operating costs.
  • It is equipped with a shell-and-tube evaporator that is resistant to pollution and operates with lower losses due to the design features.
  • Execution with several freon contours. This configuration provides high efficiency at partial loads
  • Environmentally friendly R134a refrigerant provides improved performance due to higher heat capacity
  • IP54 protection class allows chiller to be installed outdoors
  • A wide range of accessories and additional equipment kits for flexible equipment of the chiller according to the needs of the client
  • The refrigeration circuit is designed to work both with hydraulic systems under atmospheric pressure and under excess pressure (up to 6 bar)
  • Comprehensive protection system including: phase monitor, pressure switch, frost protection sensors, water level sensors, as well as a built-in water bypass circuit.
