ERGIL Storagetech™ Pressure Vacuum Relief Valves (with Humidity Control)
Humidity Control Units can be provided on all StorageTech™’s Vacuum Relief Valves, and Pressure-Vacuum Relief Valves. These are used on storage tanks that contain moisture sensitive products.
The inlet flange of the pressure relief valve raised by the addition of a flanged pipe spool, and a dehumidifier case and cartridge is attached to the inlet of the vacuum relief valve. The assembled valve is installed on a tank roof flange or a vent pipe from the vapour space.
The dehumidifier cartridges / compartments are charged with an absorbent material that requires replacing/rejuvenating at intervals relating to the climatic conditions pertaining to the location of the equipment.
