HMV container

Drazice hot water storage tank with two heat exchangers, without electric heating insert 300 litersThe SOL series can do so much more for a plain container, that 2 temperature sensor sleeves are installed in the right place,
this is important!
The OKC NTRR tanks can primarily be used as tanks for domestic hot water solar collector systems. The solar collectors must be connected to the lower and the boiler to the upper heat exchanger. The containers are equipped with 1 pc in the middle height (to control the heating of the lower heat exchanger)
and 1 thermostat located on top (to control the heating of the upper heat exchanger), as well as 1 thermometer installed on top. The containers are welded, made of sheet steel, their internal surface protection is fire enamel coating.
Thermal insulation 60 mm 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 storage tanks at approximately mid-height, through which an electric heating cartridge can be installed.< /span>
Maximum pressure of tanks: 6 bar (0.6 MPa)
