Double circulation unit

DDA100

Double circulation unit Series DDA100 is a compact unit for two separated heating circuits. One with a direct supply, and one with a mixing function. Equipped with two high efficient pumps, a valve with progressive characteristic, actuator, ball valves with thermometers, manifold with by-pass function and a insulation shell. Double circulation unit is a perfect choice for heating pumps, and boilers which are working with radiator and/or underfloor heating.

  • Compact, all in one design
  • Easy to install
  • Manifold with option of hydraulic separation easily set with a screw
  • Check valve integrated into ball valves return line
  • High flow rate
  • Possible to upgrade with upgrade kit
  • Quick-fit actuator
