DN25 thermostatic mixing unit for heating and/or cooling systems, compact and
ready for assembly. Complete with 3-way fixed point mixing valve with adjustable
thermostatic head and electronic circulator with EEI <0.21. Equipped with a ball
valve with a thermometer on the system's flow, ball valve with thermometer and
releasable non-return valve on the system's return. Covered by a black EPP heat
insulating shell. Maximum operating temperature 110°C (conform to the circula-
tor's specifications). Maximum operating pressure 10 bar. Mounting brackets not
included.
Use
The thermostatic mixing unit is a control device for heating only and combines
a number of components that make it possible to keep the delivery temperature
entering a radiant panel circuit constant, when the latter is an integral part of a
mixed heating system.
The temperature of the water entering the radiant circuit is controlled by a pre-set
micrometric valve that makes it possible to mix the water at a higher temperature,
coming from the boiler, with the return water from the radiant circuit, obtaining the
pre-set water temperature.
Therefore, this thermostatic mixing unit makes it possible to keep the heating water
supplied to a user constant.

Wall bracket to support DN25 units, with threaded nut couplings.
Use
Wall mounting bracket for DN25 units, required if the unit is assembled without
a distribution manifold or a hydraulic separator. The threaded nut couplings
connected to it replace the same couplings already on the boiler side of the unit.
