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, fruit and vegetable storage. Flat coolers with a nominal capacity from 4.3 to 106.5 kW, equipped with axial fans with diameter from 400 to 630 mm. Air is drawn in from below and blown out sideways. 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 2 205 to 44 146 m3/h.

TEDN Thermofin air coolers can be equipped with double insulated, tilting drip trays made of AlMg3, powder coated. Installation of a polyamide condensate drain is available. Optional defrost: electric (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.

Characteristics of TEDN air coolers
