Hazardard - Engineered To Perform In The Harshest Conditions
Specifically designed to cool living quarters, storage areas and other enclosures situated in hazardous locations; where specific volatile flammable liquids or gases are handled or used within enclosed containers or systems.

Hazardgard Meets T4 Temperature Classification
Unit surface temperatures will not rise above 135° C/275° F.

NOTE: 50/60Hz model listed as T4A for surface temperatures to 120° C/248° F.

Operates at low ambient conditions without freezing at outdoor ambient temperatures as low as 7° C/45° F.

Tolerates higher outdoor temperatures up to 55° C /130° F.

Durable, Quiet, Efficient
Friedrich air conditioners are hard-working and hard-wearing. Their commercial-grade products are the first choice for tough environments, from oil rigs to the Kennedy Space Center. Constructed from the highest-quality materials and components, these units are built to exacting standards - yet they are among the quietest and most energy-efficient available.

How to Choose a Room Air Conditioner
Compared to large capacity central units, room air conditioners have several advantages. The initial cost of a room air conditioning unit is significantly lower than the cost of central air. Because room air conditioners are designed for cooling small spaces, operating costs are reduced. And, room air conditioners can provide personalized temperature and humidity controls that central systems cannot.

Calculating Cooling Capacity
Cooling capacity is the critical factor in properly selecting a room air conditioner. Cooling capacity is measured in British Thermal Units (BTUs) and typical models will range in capacity from 5,000 BTUs to 28,500 BTUs.

Choosing an undersized unit will overwork the unit and it will not cool properly. Choosing an oversized unit will cost more to buy and operate and it will not dehumidify properly.

We can help you to calculate capacity. Be prepared to provide specific information on:
  • Room Dimensions
  • A simple floor plan to show the location of doors and north-facing windows
  • The number of people it will serve
  • Sources of heat such as lamps, TV and appliances
  • An explanation of what's above the intended room
  • Your insulation provisions
Cooling Capacity by Room Size
Measure the length and width of the area to be cooled. Multiply the length by the width to determine square footage or square meters. When cooling rooms with uninsulated ceilings, great rooms, or southern or western sun exposures - step up to the next BTU size.

Built To Perform In The Harshest Environments
  • Offshore oil rigs, on-shore oil company offices and refineries.
  • Petrochemical sites and propane fill-up stations.
  • Paint and varnish storage or processing plants.
  • Grain alcohol processors or storage sites.
  • Plant areas using strong solvents or chemicals.
  • Munitions plants or armories.
  • PVC or plastics plants and processing points.
  • Recycling plants.
  • Furniture refinishing/stripping workshops.
  • Fertilizer plants.
  • Office complexes where methane is a by-product.
  • Hazardous materials storage.
  • Permanent split capacitor motor.
  • 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).
  • 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).
  • Larger, commercial grade, enclosed fan motor with hermetically sealed overload for arc-free operation.
  • Totally enclosed to assure efficient operation under adverse electrical conditions.
  • Unit utilizes field 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, honeycomb matrix packaging resists damage during shipment and is environmentally friendly.
Coils Coated For Corrosion Resistance
  • Diamonblue Advanced Corrosion Protection on the outdoor coil protects the coil against deterioration.
  • And extends the life of the unit especially in coastal or corrosive environments.
