Kelvion Goedhart Customized Air Cooler VRB VRZ

The Goedhart VRB/VRZ series is part of our customized series (Goedhart engineering level 2). 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 VRB/VRZ can be flexibly and effectively designed for individual refrigeration requirements – especially for complex applications.

The coil blocks have stainless tubes expanded into fully collared aluminium fins. A good thermal contact is achieved by expansion of the tubes into the fin collars, that are also utilised as spacers to provide a constant distance between the fins. All coolers are pressure tested to 40 bar (lower by cooling mediums) and are supplied with a light over pressure charge of dried air. Suitable for NH3/CO2/H(C)FC- pump system and de system and the most coolants.

The Goedhart VRB/VRZ is an adaptability artist. With its countless possible configuration possibilities, the Goedhart VRB/VRZ can be designed spot-on for the most demanding refrigeration tasks.

Advantages
  • High performance due to application-suited circuit design
  • Variable air direction of all fan variants – blow-through as draw-through
  • Easy installation: Delivered on a wooden frame for easy mounting
  • Long-term assurance: highly efficient, ErP 2015 fans
  • 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
