Functional description:

The Water-Oil-Trap is used as a protection of gas analysers from liquids (water, acid, alkali and liquid hydrocarbons) and particles. A bypass connection is integrated.
The Water-Oil-Trap is installed directly in front of the gas analyser in the tubing. If the upstream gas processing (cooler, peristaltic pump, dust filter and the like) fails, the Water-Oil-Trap uses its semi-permeable membrane with SUN-C Dual Membrane System® to protect the gas analyser. The membrane separates gases from condensate and extra fine dust. The Water-Oil-Trap is designed as a bypass filter. The main gas flow can be discharged again via the bypass; a partial current (1:2 to 1:20) will be provided to the analyser. This results in quick response times of the analyser. Condensate/oil carried along is also discharged via the bypass. The aligned incoming flow of the diaphragm has another additional self-cleaning effect. An alarm is indicated via the upstream variable area flowmeter with monitoring (refer to sample applications).

The Water-Oil-Trap is also known as a “Police filter”.
