Kelvion Goedhart Customized Air Cooler VRB VRZ
The Goedhart VRB/VRZ series is part of our customized 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 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.
