Can refrigeration units be installed in Class A flammable and explosive workshops?
Thread Content
As the title suggests, I am currently working on the equipment layout plan. The factory building is classified as a Class A facility prone to fire and explosion; there is a refrigeration unit that the owner wants to place inside the building. No relevant regulations could be found in the standards – how should it be arranged? Those who know it, please explain the specific requirements and the standards to refer to. Thank you!
Since the factory building is classified as a Class A facility prone to fire and explosion, if this refrigeration unit is an explosion-proof model, it can naturally be placed inside the factory building. If not, then keeping it in a Class A flammable and explosive factory represents a safety hazard.
In accordance with the specifications for “cabinet rooms” as outlined in the stone industry standards
If the refrigeration unit is explosion-proof, the price is likely to be high. If there is a refrigeration unit, the corresponding supporting facilities such as a refrigerant tank should also be available; as long as it is outside the explosion zone and separated by explosion-proof walls, there should be no problems.
The engine type doesn’t matter; as long as it is an explosion-proof motor and an explosion-proof power distribution cabinet, that will suffice. If saltwater is used for the refrigerant tank, it’s fine, but if ethanol or ethylene glycol is used, the tank must be placed outdoors
