Hazardgard

Engineered to perform in the harshest conditions.

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 specically designed to cool laboratories, control

rooms, living quarters, storage areas and other enclosures situated in hazardous locations; where
specic volatile ammable liquids or gases are handled or used within enclosed containers or systems.

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. Model SH20M30SA is KSA Registered in accordance

with SASO2681 and meets SASO 2663 Energy Ef ciency 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.

Off the shelf models allow for efcient manufacturing,

shorter lead times and standardized component parts.

Product Reliability

Used across the globe, Hazardgard
is a tested and reliable product and

not a quick-x, job shop alteration.

Availability

Durability

Robust engineering, commercial
grade components and extensive

eld 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

COATED COILS FOR CORROSION RESISTANCE

PERFORMANCE IN EXTREME
CONDITIONS

• Hot gas bypass for cooling operation at

low ambient temperatures, down to 45ºF /
7ºC without freezing

• Designed to tolerate high ambient

temperatures, allowing units to operate

in T3 conditions

• ElectroFin® 5-stage, immersion ecoat process, or
Diamonblue Advanced Corrosion Protection
metallic surfaces on the outdoor coil provides outstanding
corrosion resistance protection and extends the life of the
unit, especially in coastal or corrosive environments.
