Thawing units
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.
