Pressure step de-aerators

Pressure step de-aerators are designed to provide active deaeration of micro-bubbles and dissolved air from heating and cooling systems in high rise buildings. This model is designed to create the most favourable conditions for efficient air removal where centrifugal or micro-bubble air separators can not be used, for example when the system head is too great. The basic operation involves isolating a volume of the system water in the de-aeration vessel, inducing a pressure drop with a pump to liberate dissolved air, venting and final return of the de-aerated water to the system. They can be used accordingly for the following applications:- Low Temperature Heating (LTHW) Chilled Water (CHW) Condenser Water (Cond.W)
