1 TECHNICAL SPECIFICATION OF PRODUCT
1.1 FUNCTION DESCRIPTION
OKCE line water heaters use only electricity for heating. Their nominal performance provides sufficient
amount of hot water for flat units, premises, restaurants, and similar establishments.
1.2 PRODUCT DESCRIPTION
The heater tank is welded from a steel sheet; it is entirely coated with hot water resistant enamel. For
additional corrosion protection a magnesium anode is mounted in the upper part of the heater to adjust
the electric potential inside the tank, lowing the risk of corrosion. All types have the outlets of hot and cold
water and a circulation opening welded to them. The tank is insulated with 65 mm of polyurethane foam.
The heater shield consists of a steel, powder-paint coated, sheet; the connecting parts are metal coated.
For heaters 100 – 125 l is a flange welded onto the upper bottom of the receptacle with a flange lid
screwed to it. A sealing ring is inserted between the flange lid and the flange.
Thermo wells for the safety thermostat sensors and capillar thermometer installation are placed in the
flange lid. Wiring is placed under the plastic removable cover. Under a plastic cover on the side of the
heater, there is a cleaning and revision opening ended with a flange; various performance heating units
may be mounted into the opening. The heater is to be placed on the ground.
Tanks between 100 and 250 litres are tested with the pressure of 0.9 MPa; 300 litre tanks are tested with
1.5 MPa.
