MS Series
Explosion Proof Mini-Split System
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.

Higher Efficiency, Low Profile Hazardous Cooling
The MS-CU/AH® Series is designed for applications where traditional ducted systems are impractical, such as small control rooms, analyzer shelters, or modular buildings in hazardous zones. The system features a "Mini-Split" design with a slim, wall-mounted indoor air handler connected to a powerful outdoor condensing unit.
Equipped with advanced Inverter-driven compressors and Electronic Expansion Valves (LEV), the MS Series offers superior energy efficiency and precise temperature control compared to traditional on/off systems. The units are available in both Cool Only and Heat Pump configurations, ensuring year-round climate control for critical equipment and personnel.
Inverter Technology: Variable speed compressor adapts to load for energy savings and stable temperatures
Flexible Power: Dual-rated for 208-230V/60Hz and 220-240V/50Hz global applications.
Advanced Controls: Includes a wireless handheld controller and a Division 2 approved wall-mount thermostat with LCD display.
Durability: Dense insulation for noise reduction and vibration isolation for smooth operation.
Safety: Anti-short cycle timer, auto-restart after power outage, and high/low-pressure safety circuits.
Maintenance: Washable long-life filters and easy-access panels.

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 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.
RT 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.
