Servitec degassing systems

The Servitec series offers reliable protection against gas problems in small and large systems – through the active degassing of even dissolved gases. To do so, a partial flow of water in the system is removed, degassed in the Servitec under vacuum and fed back into the system virtually gas-free. Automatically controlled ball valves guarantee a constant flow regardless of the pressure ratios in the system. The standard range is adequate for system volumes of up to 220 m³.
