Explosion proof room air conditioners, also referred to as window air conditioners, are typically used to condition small spaces needing up to 36,000 BTU's of cooling and requiring no ductwork.  Air conditioning with room units (window units) can provide an economical solution for many applications.   All room units may also be marked with the US and Canadian Class I/ Zone system upon request (example: Class I, Zone 2, group IIB+H2). 

RCBX series air conditioners and RHBX series heat pumps are CSA (C/US) certified for Class I, Division 2, Groups B, C, D hazardous (classified) locations.

Explosion proof RCBX-C1 series air conditioners are CSA (C/US) certified for Class I, Division 1, Groups C, D hazardous (classified) locations. 

RHBX-C1 series heat pumps are for use in Class I, Division 1, Groups C, D hazardous (classified) locations.

RCXG series air conditioners, with or without electric heat, have a Division 2 rating in the condenser (outdoor) section only and are for use with Type Z pressurized buildings.

Dust-ignition-proof RCBX-E1 series air conditioners and RHBX-E1 series heat pumps are for use in Class II, Division 1, Groups E, F, G hazardous (classified) locations.

Combustible dust hazardous location RCBX-F2 series air conditioners and RHBX-F2 series heat pumps are for use in Class II, Division 2, Groups F, G hazardous (classified) locations.

Options include corrosion coatings on coils and cabinets, stainless steel cabinets, and auto-changeover thermostats for heating and cooling units.
