The tank insulation is performed using NOFIRE technology with 70 mm thick, 100% recyclable polyester (which is an environmentally friendly material) with a high R-value and B-s2d0 high fire-resistance class in accordance with the European EN 13501 requirements.

On the outside, the standard design tanks with a volume of up to and including 5000 l are protected by plastic covering, or optional fabric covering. For the insulation color range, please contact the seller.

ZK ELECTRO MONO series tanks are used in systems with electric heating elements. Therefore, there can be 2 up to 10 threaded outlets with a 2″ diameter internal thread on the tank. The standard tank is fitted with only two such outlets.

The tank can also be fitted with a inspection flange for storage tank maintenance (optional).

The tank is also equipped with a spiral heat exchanger for connecting an additional heat source, such as a gas-fired boiler, solid fuel boiler, solar collector, thermal pump or central heating system.
