The double pump group DAA111 is used to mix hot water from the boiler with return water from the heating unit. The mixing unit is equipped with a 3-point actuator ARA661. Pumping water from the boiler is provided by a Wilo pump - PARA 15-130 / 8-75 / SC. The group is designed for two mixed separate heating circuits , so it has two mixing groups.

MAIN ADVANTAGES

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

non-return 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. There are also shut-off and non-return valves and two high-efficiency Wilo PARA circulation pumps. Everything is hidden in a thermal insulation jacket.

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 operating options - from two direct to two mixing units.

FUNCTION

The mixing section mixes the hot water led from the boiler and the colder water returning from the heating system. This creates the ideal required temperature, which is determined by an external temperature controller or thermostat. The mixing function is ideal for use in underfloor heating.
