harshest environments
• Offshore oil rigs, on-shore oil company
ofces and reneries
• Petrochemical sites and propane ll-up
stations
• Paint and varnish storage or processing
plants
• Grain alcohol processors or storage sites

Applications
• Permanent split capacitor motor
• Hermetically sealed refrigeration system
• Environmentally sealed on/off switch and gold plated contacts in
thermostat for corrosion resistance
• Solid-state control relays for compressor and fan operation
• Hot gas bypass allows the air conditioner to operate at low ambient
conditions without freezing at outdoor temperatures as low as 45° F (7°C)
• Hermetically sealed reciprocating compressor is cooled during the
refrigeration cycle, which allows the unit to tolerate
higher outdoor temperatures up to 130˚ F (55°C)
• Larger, commercial grade, enclosed fan motor with
hermetically sealed overload for arc-free operation.
Totally enclosed to assure efcient operation under
adverse electrical conditions
• Unit utilizes eld supplied, direct-wired, 15-amp circuit
with time-delay fuse that will tolerate current surge
without tripping the breaker
• 22-gauge, G60 steel air conditioner cabinet is powder
coated for corrosion protection and to withstand years of
hard use
• High density EPS foam insulation for thermal resistance
and sound control
• Heavy duty hexacomb packaging resists damage during shipment and is
environmentally friendly

Due to continuing engineering research and technology, specications are subject to change without notice. Manufactured under U.S. Design
Patent DES 368, 306 decorative front; Utility Patent 5, 622, 058. MAXIMUM outdoor ambient operating temperature is 130°F. (55°C) MAXIMUM
TEMPERATURE RATING FOR CLASS I, DIVISION 2, GROUPS A,B,C,D.
For global applications, Hazardgard cooling capacities are tested in a certied laboratory at moderate (T1*) and hot (T3*) climate conditions in
accordance with SASO (Saudi Arabian Standards Organization) Standard 2681. SASO Standard 2681 is adopted from ISO Standard 5151 for testing
and rating for performance of non-ducted air conditioners and heat pumps.
* Capacity and efciency values at each climate conditions are available upon request.
