Character

The OKC 250 (300, 400, 500, 750, 1000) NTR/HP stationary tank is designed for the preparation of hot sanitary water in combination with heat pump. Reheat can be carried out by the electric heater TJ 6/4".

The tank receptacle is welded of steel plate and, as a unit, protected with enamel that resists to hot water. For additional corrosion protection two magnesium anodes are mounted in the upper part of the receptacle and in the side flange to adjust the electric potential inside the receptacle, thus reducing effects of corrosion. Inside the vessel there is a welded heat exchanger made of steel pipe with enamelled outer coating, and connections of hot and cold water, circulation and thermostat tank.
