DN32 mixing unit for heating and/or cooling systems, compact and ready for as-
sembly. Complete with 3-way mixing valve, prepared for rotating servo control, and
electronic circulator with EEI <0.23. Equipped with ball valves with a thermometer
on the system's flow and return. Non-return valve on the system's return. Cov-
ered by a black EPP heat insulating shell. Maximum operating temperature 110°C
(conform to the circulator's specifications). Maximum operating pressure 10 bar.
Mounting brackets not included.
Use
The mixing unit is a control device for both heating and cooling, and combines a
number of components that make it possible to control the delivery temperature
entering a radiant panel circuit, when the latter is an integral part of a mixed heat-
ing system.
The temperature of the water entering the radiant circuit is controlled by a three-
way mechanical valve, which can be fitted with a 0-10V, 24V or 3-point 230V servo
control. This makes it possible to mix the water that comes from the boiler with the
water returning from the radiant circuit, and obtain the required water temperature,
calculated in real-time by a control unit.
The mixing unit can therefore be used to increase or lower the power supplied
for heating or cooling, adapting it to the actual radiant demand, and obtaining the
water temperature required and calculated in real-time by a control unit.
