SET Instant DHW production unit

Instant DHW production unit

SET is a “plug and play” module for instant DHW production that uses a brazed stainless steel plate heat exchanger.

SET is compact and user-friendly, featuring an electronic control unit which allows you to easily and intuitively adjust the DHW temperature, define the time bands, manage the accessories and much more, via a display.

SET is available in three versions (SET 20, SET 30 and SET 40), which differ in the DHW nominal flow rate: 20 l./ min, 30 l/min and 40 l/min which varies depending on the operating conditions

Compared to the previous version, the new SET is also preconfigured for the installation and internal control of a recirculation kit

SET ACCESSORIES

A number of accessory kits are available to be combined exclusively with the SET heater to improve efficiency, optimise consumption and make it more user friendly.

Accessory type	Accessory type
Connection kit in cascade	Allows you to connect up to a maximum of 8 instant heaters, guaranteeing a DHW production from a minimum of 2 l/min up to 360 l/min.
Recirculation kit	Controls a domestic water recirculation pump, where present, through various programs.
Mixing valve kit on primary circuit	Allows you to reach high temperatures in the primary circuit, improving the adjustment accuracy and thus, guaranteeing greater comfort.
Stratification storage tank kit (with external deviation valve)	Boosts stratification inside the hot water buffer tank and optimises the efficiency of the entire heating system.
Relay kit	External relay
