THERMITAL MODEX ACS 40 E
The ACS 40 E is an instant domestic hot water mixer. It uses a brazed, stainless steel plate heat exchanger and is desi-
gned for use in combination with DHW storage cylinders.
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 40 E instant hot water mixer comes complete with an insulated frame.
