Brownell has developed Vent Dryers to protect liquid storage vessel contents against moisture contamination in two sizes for standard and high duty applications and with a dual thread mounting option to ensure easy installation and maximum effectiveness in a wider range of applications.

As well as preventing water vapour adsorption occurring whenever vessel contents are exposed to ambient humidity during normal use, these rechargeable units also minimise pressure differential and odour emissions, give full weather protection, assist flame suppression and reduce the build-up of ignitable vapours.

An active desiccant bed retains any moisture before it can enter the vessel and field trials have proven that all existing condensation is quickly removed when these vent dryers are fitted to new vessels of polished fluid.  A colour change visible from outside tells users to change the beaded silica gel, simply by removing an access port plug, and thus ensuring full protection at all times.

Contaminated by moisture adsorption can seriously alter many of a fluid's active properties.  Opening an unprotected vessel immediately admits humidity and water vapour in the airspace contaminates the fluid when it is drawn or the air above it is displaced or moved by normal temperature variations and barometric pressure.
