Icma R002 – Mixing group with fixed point regulating unit

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.
