Air separators

HCE's POWER VENT™ air separators are float-operated and they remove air in water in plumbing systems. Water enters the device and flows into the innovative Air Trap cartridge that captures the smallest air bubbles by raising and expelling them from the top of the device. This process is constant to keep the water free of air bubbles, improving the efficiency and durability of the hydraulic system. POWER VENT™ air separators are also equipped with a high-performance 360-degree rotatable air vent valve with guaranteed discharge up to 10 bar.

It is important to install HCE POWER VENT™ air separators on the hottest side of the system, as this is the area where there is most microbubble formation. So in the case of heating systems, it should be installed on the supply side of the system. While on cooling systems, it should be installed on the return, at the inlet of the cooling unit (Chiller).

Choosing an air separator depends on several plant-specific factors. HCE offers a range of POWER VENT™ air separators suitable for any type of connection such as in-line air separators or air separators with swivel connections. The in-line air separator can only be mounted horizontally, but allows flow in either direction. The air separator with swivel connection allows it to be installed horizontally, vertically, and at 45°, while still ensuring maximum deaeration at all times. The air vent valve can be rotated 360° and allows high performance (guaranteed discharge up to 10 bar).

POWER VENT™ air separators require periodic maintenance in order to ensure better deaeration over time. Maintenance usually consists of cleaning the main body where the innovative Air Trap cartridge resides to remove any buildup of dirt or residues. A threaded connection at the bottom of the air separator allows an easy drainage and to install a drain valve.

HCE POWER VENT™ air separators with regular and proper maintenance do not need to be replaced. Of course, the life of the device can vary greatly depending on various factors that may intervene, such as conditions of use, maintenance performed and the environment in which it is installed.

HCE POWER VENT™ air separators can be installed on both boiler and heat pump systems. Thanks to the different types of connections, they can be adapted to any installation position: horizontal, vertical and 45°. However, it is essential, that the installation is carried out on the hottest side of the system, i.e., on the boiler outlet or on the return inlet to the cooling unit.
