Thawing units

The defrosting equipment accelerates the natural thawing process by supplying hot air, managed mainly by three temperature probes and a specific program. Both the two product probes (interior and exterior) and the ambient T and RH probe protect the product and guarantee a correct thawing process.

The unit consists of two interior coils, one for cooling and the other for heating, and is also equipped with a ventilation train, thanks to which we will send hot or cold air inside the room. There may be several heat sources depending on availability in the industry: hot glycol, hot gas, hot water, water vapor or electrical resistances. Once the thawing process is complete, the equipment has a cooling coil to preserve the product in optimal conditions.

Types of Thawing untis

Autonomous
The autonomous defrosting units include the refrigeration group, thanks to which we obtain both heat for thawing and cold for preserving the product once the thawing process is complete.
Centralized
  • Glycol
  • Hot water
  • Steam
  • HFO
  • HFCs
CD-4.0 Controller

This controller, developed by GREENFRIO, is an Omron PLC specially designed to control thawing chambers. It allows manual or programmed operation, with the possibility of establishing and memorizing 20 programs of up to 25 steps. It has multiple control functions, including:

  • Thawing by product probes.
  • Thawing by chamber probe.
  • Thawing with or without humidification.
  • Conservation chamber.

The thawing program has been developed to accelerate the natural thawing process and to protect the product. To this end, the following information is managed, among others:

  • Control of the air temperature in the room.
  • Temperature control in the surface layer of the product.
  • Temperature control in the center of the product.
  • Control of the relative humidity of the air in the room.
  • Control of fan operating times.
  • Defrost control.
  • Cycle completion control.
