Adiabatic Refrigerator

The solution offered by Torraval is adiabatic refrigerators is the PAD series, consisting of an air-based cooling with an adiabatic preecooling thereof that increases the performance and efficiency of the heat transfer . It's been designed to reduce water consumption, minimize energy consumption and prevent the release of aerosols to the atmosphere. It has a cooling capacity of up to 1.000 Kw.


The refrigerator automatically governs a PLC control panel supplied and programmed from the factory in accordance with the mode of operation optimized for each installation.

Dry mode: (normally in winter), the air is not pre-cooled (the adiabatic circuit is empty/out of service). The air enters the refrigerator from the top (open decks, if supplied), or through the humidifier filler, in this case dry (pump out of service).

Adiabatic mode: (normally in summer), air is subjected to a process of adiabatic pre-cooling before entering the cooler at the bottom. Once inside, it passes through the humidifier filling (closed air inlet top plates and water pump in operation).

• The unit can be commanded by BMS remote control.
