Role of Emergency Vents in Tank Safety
Emergency vents protect an internal fuel tank from being over-pressurised. It allows the tank to release the pressure and ensure safety in the event of a fire. In other words, emergency vents are pressure releasing devices preventing the tank from being ruptured due to over pressurising.
If a fire takes place near a flammable liquid storage tank, the heat passed on by the tank wall to its contents will cause vaporisation of the liquid inside. If the tank holds petroleum-based products, the expected vaporisation is about 30 or more cubic feet for every gallon of solvent. This act is bound to create a relatively high pressure within the tank, and if there’s no emergency vent available, the tank may rupture, leading to a disaster.
Such explosions can be avoided by having an emergency relief vent to allow the vapours to escape from the tank. Most emergency vents feature pallet assemblies that stay close under normal pressure and open when a predetermined pressure is reached. This relieves the abnormal volume of vapour created in case of fire conditions.
Emergency vents are essential to be installed in tanks storing flammable substances. At Ekotech, we stock and supply a range of emergency vents to meet the varying needs of fire-rated tanks.
Choose The Ideal Product For Your Storage Tank

Tank Blanketing Valves
Tank Blanketing Valves provide an effective means of preventing and controlling fires in flammable liquid storage tanks. Vapours cannot be ignited in the absence of an adequate supply of oxygen. In most instances, this oxygen is provided by air drawn into the tank from the atmosphere during tank emptying operations.
Tank Blanketing Valves are installed with their inlet connected to a supply of pressurized inert gas (usually Nitrogen), and their outlet piped into the tank's vapour space. When the tank pressure drops below a predetermined level, the blanketing valve opens and allows a flow of inert gas into the vapour space. The blanketing valve reseals when pressure in the tank has returned to an acceptable level. The blanketing gas contains no air. No supply of air (Oxygen) is allowed to enter the tank. The vapours, therefore, never form a flammable mixture.
Tank Blanketing Valves help maintain the vapour space in a non-flammable condition, and also provide make-up gas to insure that the tank's vapour space is not subjected to a vacuum.
Tank Blanketing Valves can also be utilised to protect products such as purified water or cooking oils from contaminants by maintaining a positive pressure in the vapour space of the storage tank.
