RT Series
Compact Explosion Proof Roof Top Units
The RT® Series units are engineered to provide superior performance in extreme and hazardous conditions where space is at a premium. With capacities ranging from 13,500 to 15,000 BTU/hr, these compact rooftop units are the ideal solution for crane cabins, guard shacks, and small operator buildings located in Class I, Division 2 environments.

Compact Climate Control for Critical Operations
The RT® Series is designed specifically for small footprint applications in hazardous locations. Whether cooling a crane operator's cabin high above a facility or a remote guard shack, the RT Series delivers reliable cooling in a sturdy, lightweight plastic housing designed to withstand vibration and outdoor elements.
The series offers flexibility in configuration: customers can select the "All Unit" (2T) complete system which includes the evaporator and condenser in one self-contained package, or the "Condenser Section Only" (1T) configuration. Both variations feature R410A refrigerant, dense insulation for noise reduction, and Third-Party Certification by Intertek.
Compact Footprint: Aerodynamic, sturdy plastic housing designed for roof mounting on small structures.
Advanced Controls: Built-in Division 2 LCD display for status, mode, and setpoint (Remote controls available).
Vibration Isolation: Components are isolated to reduce operating noise and withstand movement (ideal for cranes).
Global Power Compatibility: Available in 115V/60Hz and 240V/50Hz models.
Easy Installation: Includes ceiling assembly with 8-inch duct and 14x14 opening; single-point power connection.
Corrosion Options: Available with Heresite or Adsil coated coils, or 304/316 Stainless Steel housing upgrades.

The WCSK (Cool Only) and WHPSK (Heat Pump) Series provide versatile, compact climate control for hazardous locations. Designed for both land-based and offshore applications, these units feature a slide-out chassis design for easy installation through windows or walls, delivering superior performance in Class I, Division 2 environments.
WCSK & WHPSK Series
The MS Series offers a versatile split-system solution for hazardous environments where space is limited. Comprising a slim indoor air handler and a rugged outdoor condensing unit, this series utilizes inverter-driven technology to deliver precise cooling (and optional heating) ranging from 9,000 to 36,000 BTU/hr.
MS Series
The VAC Series provides robust, industrial-grade cooling and heating for extreme environments, offered in capacities from 1.5 to 6 tons. For hazardous locations requiring positive pressure, the VACPB model builds upon this platform by integrating an automatic pressurization system compliant with NFPA 496 Type Z, eliminating the need for separate filtration and blower modules.
