Akvaterm Standard Accumulator Tank
Standard steel tanks are available with capacities ranging from 300 litres to 10000 litres. The insulation is 150mm seamless polyurethane up to and including 2000l and 100mm seamless polyurethane above 2000l and all tanks are faced with a white faced cover.

Detachable side panels are also an optional extra. An uninsulated accumulator tank coated with corrosion protection paint can also be delivered. The upper hatch has a hot water coil 35 litres/minute fitted as standard.

A domestic hot water pre-heating coil, a solar heating coil and other coils can be placed in the lower hatch.

There are 2” couplings for the electrical resistors located at centre and bottom of the tank. Built-in guide pipes ensure the proper layering of heat.

The standard domestic hot water coil size is LK35 but other coils with flow rates LK45/60/80/100/120 are available on request. The standard pressure class is 3.0 Bar but the tanks are also available in 4.0 Bar and 6.0 Bar on request.
