Friedrich SH15L30, SH20L30 Direct wire connection, Hermetically sealed reciprocating compressor

This is the ONLY room air conditioner that meets the United States National Electric Code, Article 500, requirements for Class I, Division 2, Groups A, B, C, and D Hazardous Locations.

It is 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. 

For more than 30 years, the Friedrich Hazardgard has endured some of the toughest and most unforgiving operating conditions imaginable. Time-tested in the field where it counts, Hazardgard is trusted by professionals who have to get

the job done. Robust engineering with design details like 33% thicker fins extend the life of the coil. Diamonblue Technology, our anti-corrosive treatment, provides

added endurance and protection in coastal or corrosive environments.

Direct wire connection

Utilizes direct-wired, 15-amp circuit with time-delay fuse that will tolerate surge current without tripping the breaker.

Hermetically sealed reciprocating compressor

The compressor motor is cooled during the refrigeration cycle, which allows the unit to tolerate higher outdoor temperatures.

Heavy gauge steel

20 gauge steel is used in order to create a more robust air conditioner cabinet that will withstand years of hard use.

Enclosed fan motor

Larger, commercial grade fan motor with hermetically sealed overload for arc-free operation. Totally enclosed to assure efficient operation under adverse electrical conditions.

Diamonblue Technology

Anti-corrosive treatment provides added endurance and protection in coastal or corrosive environments.

“This air conditioner is made like a tank.”
