We offer a variety of Thermofin glycol air coolers for use in industrial refrigeration systems such as cold stores, distribution and storage centers, freezers and deep freezers. Ceiling-mounted cubic coolers with one-sided blowing, rated power from 2.9 to 294.0 kW. They are equipped with axial fans from 1 to 4 pieces, with a diameter of 400 to 910 mm. Airflow ranges from 2,972 to 126,220 m3/h.

The large heat transfer surface minimizes heat spread and reduces drying of stored goods, ensuring long-term freshness of food. The individual design of each glycol air cooler guarantees optimal use in refrigeration units.

Thermofin TGN coolers can be fitted with double insulated aluminum and magnesium tilt trays, powder coated. Refrigerant connections on the right side, electrical connections on the left side with respect to airflow. Optional defrost: electric (defrost heaters are located in the block and tray), hot gas, glycol or water types. Standard housing made of galvanized steel powder coating of RAL 9010 color makes up a robust, self-supporting structure.
