We are pleased to offer a series of Thermofin industrial air coolers TENA with one-way blow, optimized for use in the storage of fruit and vegetables. Ceiling coolers are equipped with forcing fans and support the "Coanda effect". The advantage of this series is that block parameters are optimized for this type of application. In addition, the very low degree of drying out of the stored products is due to the large heat transfer area and the small difference between the inlet temperature and the evaporation temperature. Thermofin fruit and vegetable coolers, with a nominal capacity of 7.0 to 160.1 kW, are equipped with axial fans with diameter: from 400 to 630 mm.

The standard housing is made of aluminium or galvanized sheet steel and  has a food-safe RAL 9010 powder coating. TENA coolers can be equipped with double-insulated, hinged AlMg3 drip trays. Installation of the polyamide condensate drain is available. A linear arrangement of copper tubes was used in the block fin tube. Blades made of pure aluminium with a gap: 4.0; 7.0; 10.0; 12.0 mm. Refrigerant connection located in the airflow direction on the left side. To prevent oxidation, the exchangers are brazed under a protective gas atmosphere. Alternative: epoxy-coated aluminized fins and medium connection in the airflow direction on the right side.

A range of evaporators available in a wide capacity range for pump drives and DX systems.
