Icma R001 – Mixing group with variable point regulating unit

Mixing group with variable point regulating unit. It is provided with a three way mixing valve regulated by a 3-point modulating and bidirectional rotating electric servomotor, connectable to regulating control units; the valve has a By-Pass which brings a portion of the return side flow into the delivery side to obtain the desired temperature of the fluid. The pump has 1”1/2 connections and it can be asynchronous (not for sale in the EU) or electronic. The mixing group is also equipped with 2 interception ball valves with built-in thermometer to instantly read the delivery and return flow temperatures (the return ball valve has a built-in check valve). It can be ordered without pump, with delivery pump to the right or to the left-hand (in case of any changes on site please follow the technical sheet instructions included in the package); the group is supplied with a black PPE insulated shell.

The mixing and circulation groups are used to adjust distribution and temperature of the heat carrying fluid
in multi-storey and/or multi-zone systems.
They are ideal for underfloor heating systems and/or high temperature heating systems. The groups R001 can
be installed on a special “inlet-outlet” distribution manifold (art. 785), after the hydraulic separator.
The groups are supplied with insulation shells and fastening brackets.
