Our slim tanks have 1 and 2 heat exchangers. The inner surface is coated with glass-lined. The insulation is made of non-removable rigid PU foam for 200, 250 and 300 litre tanks and removable NEODUL insulation for 800 litre tanks. The cathode protection is provided by a magnesium protective anode in the tank. The internal heat exchanger is a permanently welded smooth-bore coil, which is enamelled together with the tank.

The indirectly heated storage tank is suitable for the production of domestic hot water, the internal heat exchanger(s) can be connected to a heating appliance, a heated buffer storage tank, a solar collector system.

The maximum allowable working pressure of the storage tank is 10 bar, the heat exchanger can be used with a maximum pressure of 16 bar. The maximum operating temperature of the storage tank under pressure is 95°C, the maximum operating temperature of the heat exchanger is 110°C.

Storage types:
– BSF-SLIM: with one heat exchanger
– SOI-SLIM: with two heat exchangers
