Goedhart ZGB/ZGZ


Goedhart ZGB (blow-through) or Goedhart ZGZ (draw-through), floor or ceiling mounted flexible industrial air coolers for cooling and freezing applications.

The Goedhart ZGB/ZGZ range is part of our customized 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 ZGB/ZGZ 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 air cooler coils are pressure tested to 40 bars and supplied with a light overpressure charge.


  • High performance due to application-suited circuit design
  • Variable air direction of all fan variants
  • Long-term assurance: highly efficient, ErP 2015 fans
  • Customize the air cooler with many available options and accessories
  • Flexible power spectrum due to a numerous of variants and configuration possibilities
  • Higher specific power, reduced fan speed and air velocity through the coil and significantly reducced current consumption
