Brownell has introduced a new range of tank vent dryers in high stainless steel to compliment their existing and aluminium versions. The dryers and adsorbents prevent valuable fluid materials form being contaminated by harmful moisture condensation. The Brownell Mark 6 tank vent dryers are suitable for use in aggressive and hostile environments such as the North Sea, and are designed for use with storage tanks containing corrosive fluids such as acid and alkalis. Typical locations would include chemical sites, plant works and processing installations. The dryers are offered in five different sizes. Optional electronic detectors enable users to constantly monitor the efficiency and capacity of the dryer. Saturated adsorbents can be identified by an alarm, taking away the need for routine manual monitoring.
