Dirt and Air Separators

Our range of high quality separators includes air separators, dirt separators and combined dirt and air separators. We also produce the CXX combined a dirt and air separator with a balancing tank, offering excellent value when compared to separate units.

CXC - Combined Dirt and Air Separator

Dutypoint CXC combined dirt and air separators can be used instead of individual deaerators and dirt separators. These combined units are very efficient and extremely cost effective, becoming the preferred standard option throughout the industry. In heating systems, the units should be installed in the flow loop, situated immediately after the boiler and prior to the pump. In a chilled water system the unit must be located in the return loop close to the chiller.
