The double pump group DAA111 is used for mixing hot water from the boiler with return water from the heating unit. The mixing units are equipped with a 3-point actuator ARA661. Water circulation from the boiler is ensured by a Wilo - PARA 15-130/8-75/SC pump. The group is designed for two mixed separate heating circuits, thus it features two mixing groups.

MAIN ADVANTAGES

Compact all-in-one design
easy installation
manifold with the possibility of hydraulic separation, adjustable thanks to a screw

check valve integrated in the ball valve
high flow rates
quick-release drive
requires almost no maintenance

The pump group consists of two mixing groups. The mixing part is composed of a mixing valve controlled by an actuator. It includes shut-off and check valves and two highly efficient Wilo PARA circulation pumps. Everything is enclosed in a thermal insulation casing.

The mixing units of the pump group DAA111 can be converted into a direct group by disconnecting their parts. The group thus offers a wide range of operational possibilities - from two direct to two mixing units.

FUNCTION

The mixing part mixes hot water led from the boiler with cooler water returning from the heating system. This creates the ideal required temperature, determined by an external temperature regulator or thermostat. The mixing function is ideal for use in underfloor heating.
