CALEFFI HED®, High-efficiency deaerator.

These are devices that, thanks to their special structure, are able to separate microbubbles from the flowing medium. The active part of the valve consists of an element that causes flow turbulence, which facilitates the release of microbubbles. Air bubbles combine with each other, increasing their volume. They then rise to the top of the device, where they are collected and later released by an automatic vent valve. Air separators are mounted on the installation's power supply line just behind the heat source, which is extremely important because this is where the greatest accumulation of microbubbles occurs.
