Water-Trap WT 20.5

Description

Functional description:

The Water-Trap is installed directly in front of the gas analyser in the piping. If the upstream gas processing (cooler, perestaltic pump, dust filter and the like) fails, the Water-Trap uses its semi-permeable SUN-C membrane^® to protect the gas analyser.
The membrane separates gases from condensate and extra fine dust. If it is fully filled, the gas flow will be interrupted. An alarm is indicated via the upstream flowmeter with monitoring (refer to sample applications).

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

Additional information from experience:

If the filter element, of the dust filter located in the gas processing is changed, particles are consistently dissolved and directed into the analyser. The downstream Water-Trap prevents this contamination as well with its diaphragm pore size of 0.1 μm.
