MISSION CRITICAL HVAC MANUFACTURER

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.
