We are pleased to offer a series of Thermofin glycol air coolers with two-way blow, for use in industrial refrigeration systems, such as logistic centers, storage of bananas, carrots and others. Ceiling flat coolers with a nominal capacity from 2.5 to 106.0 kW. They are equipped with axial fans from 1 to 4 pcs, with diameters from 400 to 630 mm. Airflow ranges from 2 218 to 44 378 m3/h.

The large heat exchange surface minimizes temperature spread and reduces the drying of stored goods, ensuring long product freshness. The individual design of each device guarantees the optimization of applications in refrigeration units.

Thermofin TGDN glycol air coolers can be equipped with double insulated, hinged drip trays made of AlMg3, powder coated housing. Installation of a polyamide condensate drain is available. Optional defrost: electric (heaters in block and tray), hot gas, glycol or water types. The standard galvanized, RAL 9010 steel powder-coated housing makes up a durable, self-supporting structure.

Characteristics of TGDN glycol air coolers

  • nominal capacity: from 2.5 to 106.0 kW
  • airflow: from 2 218 to 44 378 m3/h
  • refrigerant: ethylene glycol
  • block fin tubes:
    • aluminum fins
    • fin spacing: 4.0; 7.0; 10.0 mm
    • parameters of block: 50 x 50 mm
    • 16 mm copper tubes
  • axial fans:
    • AC or EC optionally controlled by 0-10V or 4-20mA signal or Modbus signal
    • from 1 to 4 pcs with diameters from 400 to 630 mm
    • two-way air discharge (fans force air through the block fin tube to two sides)
    • motors with an external rotor with IP54 protection class (optional IP55 for EC)
    • motors equipped with thermal protection on the winding

Accessories of glycol air coolers:

  • heating coil - air drying
