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.

CXX - Balancing Tank with Dirt and Air Separator

The Dutypoint CXX combines the benefits of a deaerator, a dirt separator and a hydraulic balancing tank in one unit.  This can be used instead of an individual deaerator and dirt separator, incorporating the added advantage of creating a perfect hydraulic balance between the primary and secondary circuits.  The importance of having a well-balanced system cannot be over-emphasised, as this greatly reduces energy consumption and increases boiler or chiller efficency. It is vastly more cost effective to purchase this combined unit rather than individual items - saving both initial cost and time on installation.
