Kelvion Goedhart Customized Air Cooler ZFB ZFZ

The Goedhart ZFB/ZFZ range is part of our industrial series. The advantage: A very high degree of customization is evident. Circuits matched to application give great performance and the optimized heat exchanger geometry have a greater specific output of the heat exchanger.

This High Performance Air cooler is available for both air flow directions (draw-through and blow-through). As a result, the Goedhart ZFB/ZFZ can be flexibly and effectively designed for individual refrigeration requirements – especially for complex applications.

The coil blocks have steel tubes and steel fins hot dipped galvanized and are suitable for NH3, CO2 and Coolants as a cooling medium. All evaporator coils are pressure tested to 40 bars and supplied with a light overpressure charge. Standard refrigerant connections are positioned on the left hand side of the unit when looking with the direction of the airflow.

  • High performance due to application-suited circuit design
  • Delivered on a wooden frame for easy mounting
  • Long-term assurance: highly efficient, ErP 2015 fans
  • Variable air direction of all fan variants – blow-through as draw-through
  • Customize the air cooler with many available options and accessories
  • Higher specific power, reduced fan speed and air velocity through the coil and significantly reducced current consumption
