KHA series of air separators remove air bubbles in water from hot water systems and cooling systems by collecting them on to surface of specially designed separator and by discharging them to outside of the system with air plug. Air bubbles in installments can result causing oxygen corrosion in heating and cooling systems, cavitation in pumps and system element, preventing heat transfer by sticking on heat transfer surfaces, Vibration and disturbing noises in the system. Using in steel, cast iron and cascade boiler systems is recommended.
