We are pleased to offer a series of Thermofin ceiling air coolers, for use in industrial refrigeration installations, such as: cold stores, distribution and storage centers, freezers and deep freezing. Cubic coolers with one-way blow, adapted to work with the refrigerant R717 (NH3). Series with nominal capacity from 4.2 to 179.3 kW, equipped with axial fans with diameter from 400 to 910 mm. 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 applications in refrigeration applications. Airflow ranges from 3 158 to 94 464 m3/h.

TAN Thermofin air coolers can be equipped with double insulated hinged drip trays made of AlMg3, powder coated. Installation of the polyamide condensate drain is available. Air coolers are equipped with refrigerant connections on the right, electrical connections on the left, in relation to the air flow. Optional defrost: electric (defrost heaters placed in block and tray), hot gas, glycol or water. Standard body made of galvanized steel with RAL 9010 powder coated housing (line 040, 045, 050 with AlMg3) that is durable and has a self-supporting structure.
