Transformers for Hazardous Locations
For industrial applications where the common Epoxy Encapsulated transformer can be cost prohibitive or may otherwise be in-sufficient, Rex Power Magnetics now offer the HLA, HLB & HLC line of Dry Type Transformers specifically engineered for Hazardous Locations and Harsh Industrial Environments.
Hazardous Locations and Harsh Environments typically refer to areas which may contain dangerous and corrosive, explosive or combustible gases, liquids or dust. Typical applications include the mining, petrochemical, pulp and paper industries to name a few.
Features
The Rex Power Magnetics line of HLA, HLB & HLC transformers are made in accordance with CSA Standard C22.2 No. 213-M1987 and the Canadian Electrical Code, Part II, CAN/CSA-C22.2 No. 0-M91 and feature the following:
- Class 1, Division 2, Groups A, B, C & D
Group A: atmospheres containing acetylene;
Group B: atmospheres containing butadiene, ethylene oxide, hydrogen (or gases of vapours equivalent in hazard to hydrogen, such as manufactured gas) or propylene oxide
Group C: atmospheres containing acetaldehyde, cyclopropane, diethyl ether, ethylene, hydrogen sulphide, or unsymmetrical dimethyl hydrazine (UDHM), or other gases or vapors of equivalent hazard
Group D: atmospheres containing acetone, acrylonitrile, alcohol, ammonia, benzene, benzol, butane, ethylene, dichloride, gasoline, hexane, isoprene, lacquer solvent vapours, naphtha, natural gas, propane, propylene, styrene, vinyl acetate, vinyl chloride, xylenes, or other gases or vapours of equivalent hazard
- Class 1, Zone 2, Groups IIA, IIB, II2
Group IIA: atmospheres containing acetaldehyde, acetone, cyclopropane, alcohol, ammonia, benzene, benzol, butane, ethylene, dichloride, gasoline, hexane, isoprene, lacquer solvent vapours, naphtha, natural gas, propane, propylene, styrene, vinyl acetate, vinyl chloride, xylenes, or other gases or vapours of equivalent hazard
Group IIB: atmospheres containing acrylonitrile, butadiene, diethyle ether, ethylene, ethylene oxide, hydrogen sulphide, propylene oxide, or unsymmetrical dimethyl hydrazine (UDHM), or other gases or vapours of equivalent hazard
Group IIC: atmospheres containing acetylene, carbon disulphide, or hydrogen or other gases or vapours of equivalent hazard.
