Evaporadores Centrifugos CN – CNH

Centrifugal Coolers

The centrifugal aircoolers CN y CNH are designed for refrigeration of workrooms or any installation where a greater air pressure is required.

  • CN: For refrigeration with positive evaporation temperature or workrooms.
  • CNH: With coils for heating for a better humidity control.
  • Capacity: 4,6 kW – 162 kW

More information on some of the industrial centrifugal coolers  CN/CNH constructive characteristics is given bellow. Click each button to display the required details:

  • Built with high-quality raw materials: 5/8” copper tubes (0,43 mm thickness) expansion-jointed in aluminium fins with 5 mm.
  • Internal careful cleaning of tubes.
  • Pressure checked: supplied with a dry nitrogen charge.
  • Outlet connection and liquid distributor, with the circuits and lengths appropriate for each application.
  • Can be supplied:
    -Equipped for GLYCOL WATER or similar.
    – With different fin spacing.
  • The sizes can be adequated for the required customer needs on demand.

  • Structurally solid casing, in aluminium with white removable protection plastic.
  • Laterals easy to dismantle to manipulate the expansion valve and the electrical connections.
  • Turbine frame for a fast and convenient frontal extraction.
  • Stainless steel bolts and supports.
  • External and internal tray, to avoid external condensation, in aluminium, with hinges, for an easy and convenient intervention.
  • Possibility of supply in:
    -STAINLESS STEEL, for a wider application, even in the strictest sectors of the food chain.

    -different ELECTRICAL specifications to those mentioned.

In the electric defrost, the principal resistance characteristics are:

  • Reinforced stainless steel materials, with vulcanized terminals on the tube: high protection against humidity and ice.
  • Strategically distributed, depending on the air cooler heat requirement.
  • Featured with special fixation on the end, to prevend movements by dilation.
  • Can be supplied:
    -Water defrost (WD)
    -Heated gas defrost (HT)
