Evaporating units

We provide unit coolers that are a critical component of Cold Room solutions. These have easy-to-use and convenient defrosting systems at sub-zero temperatures.

They are designed to occupy minimum space while housing powerful fins and a superior quality cooling coil that deliver maximum performance – every hour, every day!




Description

The heart of the refrigeration system is a high quality, efficient and effective evaporating unit comprising of

Features

  • An evaporator coil
  • Sheet metal components
  • Fans
  • Expansion device
  • Defrost apparatus

The range of refrigeration evaporator units is very exhaustive consisting of capacities from 25kW to 65kW & temperatures ranging from 22oC to -55oC.

Salient Features of Refrigeration Evaporator Units

  • Superior quality cooling coil.
  • Proper sizing for efficient cooling.
  • Proper fin spacing.
  • Imported IG-CU pipes with proper joining and brazing system.
  • Fans with required CFM, premium and safety – inbuilt features.
  • Defrosting arrangements: 0oC with no defrost required except air defrost with thermostat; with electric and hot gas defrost systems in negative temperature applications.
