HWC DOMESTIC HOT WATER CYLINDER

The HWC storage cylinders are made especially for domestic

hot water production in combination with heat pumps, thanks to

the inside coil with large heat exchange area.

The heat pump is connected to the inside coil that heats the

domestic hot water contained in the storage tank.

Legionella prevention cycles are managed by an electric heater

that can be installed in the fitting provided on the flange.

The Legionella prevention cycles are managed by the NadiSys-

tem controller on the heat pump.

Technical specifications

The cylinders are made from

S275JR steel plate in accordance

with DIN 4753 and undergo strict

water pressure tests (9 bars,

allowing an operating pressure of

6 bars). Lined on the inside with

double layer of enamel in accor-

dance with DIN 4753.

Protection against corrosion guar-

anteed by the magnesium anode,

provided with the accessories

supplied as standard with the

storage cylinder. The cylinders

are protected on the outside by

50 mm rigid CFC-free PUR lining

with white skai casing.

The combinations proposed exclude the 0061 and 0091 heat pumps, which

require the TPS series storage tanks.
