Water alarm units WW 6 series

Reliable unit for the detection of free water in oil, little indication volume makes it also suitable for small reservoirs

• Reliable physical detection method
• Visual and electrical control
• Small indication volume
• Easy installation with installation kit

Water is an unwanted contaminant in hydraulic oil and particularly in lubrication oil. The presence of water changes the chemical properties of the liquids and consequently, it reduces the lifetime of the fluids significantly. Lubrication oil is particularly vulnerable to water because high bearing pressure can generate steam formation and hence deteriorate the lubrication film.
Depending on the formulation of the oil composition, ingressed water is separated from the oil and sinks because of the higher density to the bottom of the tank.
The free water is collected in the water alarm units and raises a signal if a certain volume is reached. The water, then, is drained off either automatically or manually
