Indirect storage

Drazice is a domestic hot water tank with a heat exchanger, without an electric heating pad, 300 liters
5 years warranty.

The OKC NTR storage tanks can primarily be used as storage tanks for domestic hot water production solar collector systems.
The solar collectors must be connected to the lower heat exchanger.

The containers are welded, made of sheet steel, their internal surface protection is fire enamel coating.
Thermal insulation is 60mm thick hard polyurethane insulating foam foamed directly on the tank body.
The additional surface protection is provided by a magnesium anode screwed in from above.

There is also a 6/4" socket on the containers at approximately mid-height, through which an electric heating cartridge can be installed.
Maximum pressure of reservoirs: 6 bar (0.6 MPa)
