We are pleased to offer a series of Thermofin ceiling air coolers with two-sided discharge, for use in industrial refrigeration systems, such as logistic centers, fruits and vegetables storage. Flat coolers with a nominal capacity from 3.3 to 93.4 kW, equipped with axial fans with diameter from 400 to 630 mm. Adapted to work with the natural refrigerant R717 (NH3). The large heat exchange surface minimizes temperature spread and reduces the drying of warehouse goods, ensuring long product freshness. The individual design of each device guarantees the optimization of use in refrigeration systems. Airflow units from 2174 to 44146 m³/h.

TADN thermofin air coolers can be equipped with double insulated, hinged drip trays made of AlMg3, powder coated. Installation of a polyamide condensate drain is available. Optional defrost: ele ctric (heaters in block and tray), hot gas, glycol or water. Standard body made of galvanized steel with RAL 9010 powder coated housing that is durable and has a self-supporting structure.
