Description

The cooling plants for supermarkets “efimarket” are cooling production centrals specially designed for refrigeration and air-conditioning of medium sized supermarkets, with indirect system of positive cool distribution by glycol water pumping, as well as cool/heat distribution for air-conditioning by a double water circuit.

Advantages of cooling plants for supermarkets efimarket
  • Combination of positive cooling and air-conditioning.
  • Cooling distribution by propilenglycol for positive cool and by water for air-conditioning.
  • Low energy consumption.
  • Heat recovery for air-conditioning and cooling production economizer.
  • No refrigerant leaks.
  • Compact design for outdoors installations or working rooms.
  • Tropicalized design for ambient temperatures up to 45 ºC.
Construction of efimarket cooling plant

The efimarket cooling plants have a very compact construction comprising ar134a hermetic circuit along with hydraulic groups to pump glycol and water. They are available in two versions:

  • Series TWV-SY: with low noise axial fans for outdoors installation.
  • Series TWV-SCY: with radial fans and available static pressure for installation in engine rooms and condensed air ducting.
