Our plants supply an appropriate flow of refrigerated mixture (water + propylene glycol for alimentary use) which pass through cooling coils, plates, air spaces or heat exchangers and permits the product to reach the requested temperature.

The WINUS company supplies to all the customers dimensioning and technical calculations of all the components of the plant.

The CRM single-block cooling units are fitted on wheels and feature one or two hermetic compressors using HFC R407c refrigerant.

The finned coil evaporators and condensers have a large exchanger surface. The axial fans are protected by grilles.
All the casing, including the base supporting the components, is made of AISI 304 stainless steel, as well as all the hydraulic circuit components, including the cold water storage tank, externally insulated to prevent heat dispersion and the formation of condensation.

Two electric service pumps are also made of AISI 304 stainless steel.
The cooling circuit includes an expansion valve with external equaliser, drying filter, flow indicator and receiver vessel.
The electrical panel is housed in a CEI-approved painted galvanised metal case and includes remote switches, a thermostat, fuses, LED's and a main switch.
