Explosion-Proof Units
Overview
Conventional refrigerators and freezers are not suitable for
storing flammable materials. Such units have components in
their electrical and refrigeration systems that can trigger
explosions of flammable air-vapor mixtures inside the unit
and/or in the immediate surrounding area.
The Authority having Jurisdiction (AHJ) determines if work
areas are designated as a hazardous location with respect to
the presence of flammable gases or vapors. Such locations
are defined in (National Fire Protection Agency) NFPA 70
Articles 500-501 and OSHA 29 CFR1910.307. Some of these
classified areas are expected to experience concentrations of
flammable gases and/or vapors at or above their lower
flammability limits for extended periods of time. The
construction of our explosion-proof units has been evaluated
by Underwriters Laboratories (UL) and are suitable for use in
classified areas requiring Class I, Groups C and D* protected
equipment. The electrical components such as thermostats,
wiring, splices, relays and compressor motors on explosion-
proof units are safely housed within explosion-proof
enclosures and conduit. Compressor surface temperatures
have been evaluated and determined to remain below the
flash point of materials found in Class I, Groups C and D. All
models have heavy-gauge, rigid, steel construction with a
durable enamel finish. Interiors have epoxy enamel or ABS
plastic construction. Each unit is insulated throughout for
energy-efficient operation.
These units are ideal for storing cyclopropane, ethyl ether,
ethylene, acetone, alcohol, benzene, butane, gasoline,
hexane, lacquer solvent vapors, naphtha, natural gas or
propane along with many other potentially hazardous
materials.
*The notation Class 1, Groups C and D is an accepted
abbreviation for Class I, Div 1, Groups C and D.
