HAZARDGARD MEETS T4 TEMPERATURE CLASSIFICATION
- Unit surface temperatures will not rise above 135° C/275° 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.
For more than 30 years, industrial professionals have trusted Hazardgard to deliver safe and reliable cooling in the most extreme conditions. Hazardgard is specifically designed to cool laboratories, control rooms, 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® is rated for these conditions:

For global applications, Hazardgard cooling capacities are tested in a certified 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. Model SH20M30SA is KSA Registered in accordance with SAS02681 and meets SASO 2663 Energy Efficiency standard.
The Friedrich Advantage: Reliable Design Backed by Robust Engineering
Quality
Friedrich is an established player in the air conditioning industry and is known for manufacturing quality products.
Product Reliability
Used across the globe, Hazardgard is a tested and reliable product and not a quick-fix, job shop alteration.
Availability
Off the shelf models allow for efficient manufacturing, shorter lead times and standardized component parts.
Durability
Robust engineering, commercial grade components and extensive field testing provide the durability and safety required in hazardous locations.
DURABILITY & RELIABILITY
- 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
- Commercial grade, enclosed fan motor with hermetically sealed overload for arc-free operation
- Direct-wired (field supplied), 15-amp circuit with time delay fuse that will tolerate current surge without tripping the breaker
- Powder Coated 22-gauge, G60 steel air conditioner cabinet for corrosion protection and to withstand years of hard use
- Stainless Steel Fan Shaft
- Coated Coils for Corrosion Protection
PERFORMANCE IN EXTREME CONDITIONS
- Hot gas bypass for cooling operation at low ambient temperatures, down to 45°F / 7°C without freezing
- Designed to tolerate high ambient temperatures, allowing units to operate in T3 conditions
COATED COILS FOR CORROSION RESISTANCE
ElectroFin® 5-stage, immersion ecoat process, or Diamonblue Advanced Corrosion Protection® on 100% of metallic surfaces on the outdoor coil provides outstanding corrosion resistance protection and extends the life of the unit, especially in coastal or corrosive environments.
