BERETTA ACS 35 T LOW ENERGY

The 

ACS 35 T

 is an instant domestic hot water mixer. It uses a brazed, stainless steel plate heat exchanger and is ideal 

for use in combination with DHW storage cylinders.

Temperature of the hot water delivered to the taps is regulated by the thermostatic mixing of water in the primary circuit.

The primary circuit pump is controlled by a flow switch in the DHW circuit, connected in series to the pump. The product 

is equipped with two filling/drain cocks. When the shut-off valves are closed, these can also be used to flush out the heat 

exchanger.

A domestic hot water recirculation kit is available for further convenience.

The 

ACS 35 T

 instant hot water mixer comes complete with an insulated frame.
