1.1 FUNCTION DESCRIPTION
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".
1.2 DESIGN AND BASIC DIMENSIONS OF TANK
1.2.1 PRODUCT DESCRIPTION
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.
The pipe heat exchanger is only intended for the heating circuit.
There is a cleaning and revision aperture on the side of the tank, ended with a flange of 110 mm clearance;
the spacing of eight M8 screws is 150 mm. The heater is equipped with a G 1 1/2" aperture for screwing
an additional heater in. This variant is used - if the tank is connected in a system with heat pump - to finish
heating water in the upper part of the tank to the desired temperature. Insulation of the receptacle is 50
or 60 mm Freon - free polyurethane foam; the shell of the tank is plastic.
