Cabinet Air Conditioners for Enclosures, Panels & Harsh Environments

Cabinet air conditioners are specialized cooling systems designed to protect electronic enclosures, control panels, and mission-critical equipment from overheating. Unlike residential or commercial HVAC units, these systems are rated for continuous duty in high-temperature, dusty, or hazardous industrial environments.

Pelmar Engineering offers a complete portfolio of cabinet air conditioners across multiple mounting styles and NEMA ratings, giving operators the flexibility to select the right unit for their facility.

Why Choose a Cabinet Air Conditioner?

  • Prevent costly downtime caused by overheated drives, PLCs, and control electronics.
  • Protect sensitive equipment with closed-loop designs that keep dust, moisture, and debris out.
  • Ensure compliance and safety with models certified for hazardous locations (Class I Div 2, ATEX, IECEx).
  • Maintain stable production environments in industries ranging from manufacturing to mining.

Mounting Options Available

  • Top Mount Air Conditioners: Save floor and wall space while directing airflow from above.
  • Surface Vertical Mount Air Conditioners: Ideal for taller cabinets needing uniform vertical cooling.
  • Internal Mount Air Conditioners: Installed inside the cabinet for added protection.
  • Hazardous Location Air Conditioners: Certified for explosive or high-risk environments.

Typical Applications

  • Electrical control cabinets on factory floors
  • Data enclosures in server rooms and IT facilities
  • Food and beverage processing equipment requiring washdown protection
  • Oil & gas, petrochemical, and chemical plants with hazardous classification needs
  • Heavy industry, mining, and energy sectors where rugged, continuous cooling is essential

FAQs about Cabinet Air Conditioners

Cabinet air conditioners are engineered for higher cooling capacities, continuous 24/7 operation, and rugged environments. They feature NEMA 12, 4, or 4X enclosures, vibration resistance, and certifications for hazardous locations, making them suitable for demanding industrial settings.

Begin with the enclosure’s internal heat load (wattage of equipment) and add external heat sources such as ambient temperature and solar gain. This determines the required BTU/hr rating. Pelmar provides support tools and engineering assistance to ensure the selected unit is properly sized.

  • Top-mount units are installed on the cabinet roof, saving space.
  • Surface vertical units mount to the side and are suited for taller enclosures.
  • Internal units mount inside the enclosure, providing maximum external protection. Choosing between them depends on available space, airflow requirements, and environmental conditions.

If your facility handles flammable gases, vapours, or dust (such as petrochemical plants, refineries, or grain processing), hazardous-rated models are required. These are third-party certified (Class I Div 2, ATEX, IECEx) to operate safely in explosive atmospheres.

Maintenance is typically limited to filter changes, airflow checks, and occasional inspection of condensate lines. Units designed for NEMA 4X environments include stainless steel or corrosion-resistant housings, extending service life in washdown or chemical settings.

Yes. Cabinet air conditioners are built for continuous duty, ensuring stable conditions for equipment and processes. Many models include overload protection and diagnostics for additional reliability.
