The Kelvion VNS range is part of our customized industrial series. The advantage: A very high degree of customization is evident. The coil blocks have copper tubes mechanically 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 almost all known refrigerants and coolants, with the exception of NH3. Standard refrigerant connections are positioned on the left hand side of the unit when looking with the direction of the airflow.
