1PRODUCT TECHNICAL SPECIFICATION
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, reducing the risk of corrosion. All types have the outlets of hot and
cold water and a circulation opening welded to them. The receptacle is insulated with 40-65 mm
polyurethane foam. The heater shield consists of a steel, powder-paint coated, sheet; the connecting parts
are metal coated.
In 100-125 litre heaters, a flange is welded onto the upper bottom of the receptacle to which the lid of the
flange is screwed. A sealing ring is inserted between the flange lid and the flange.
Thermowells for placing a heating element and regulation and safety thermostat sensors and capillary
thermometer are located in the flange lid. Electric wiring is placed underneath the plastic removable cover.
Under the plastic cover in 160-250 litre heaters, there is a cleaning and revision opening ended with a
flange on the side of the heater; a heating unit of different power can be mounted in 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.
