Overview
High-temperature NEMA 12 (IP54) Cabinet Cooler Systems by EXAIR for continuous operation in ambient temperatures from 125°F to 200°F (52°C to 93°C). Systems use a vortex tube to produce cold air from compressed air with no moving parts. Continuous-operation models include a 5-micron water‑and‑dirt filter separator and a cold air distribution kit for targeted cooling and enclosure purge.

Applications

• Programmable controllers (PLCs)
• Line control cabinets
• Motor control centers
• Relay panels
• NC/CNC systems
• Modular control centers
• CCTV camera housings
• Computer and electronics cabinets
• Laser housing cooling
• Industrial electronic scales

Advantages

• Rated for ambient temperatures up to 200°F (93°C)
• Low acquisition and lifecycle cost
• Compact, panel-mounted installation through standard knockout
• Cooling capacities up to 5,600 Btu/hr (1,641 W)
• Quiet operation; sound can be reduced with optional muffler
• Preserves NEMA 12 integrity (IP54) and prevents ingress of dust and oil
• Creates slight positive pressure to purge contaminants
• No CFCs and no internal fans or filters required
• No moving parts — minimal maintenance
• Reduces nuisance trips and heat-related failures

How it works
Compressed air enters the vortex-tube-powered Cabinet Cooler and splits into hot and cold streams. Hot air is exhausted and muffled; cold air is discharged into the enclosure via the cold air distribution kit. The device maintains slight positive pressure to purge contaminants and prevent ingress of outside air.

Other considerations

• Filtration: Continuous systems include a 5 µm automatic‑drain water‑and‑dirt filter separator. If oil is present, add a coalescing/oil‑removal filter.
• Cold Air Distribution Kit: Flexible tubing, connectors and clips direct cold air to the enclosure interior or specific hot spots.
• Humidity: Continuous units stabilize enclosure relative humidity at ~45% when sealed, preventing condensation.
• Inlet Air Temperature: Expect ~54°F (30°C) temperature drop from supply air at 100 PSIG; higher inlet temperatures or lower pressure reduce capacity.
• Mounting: NEMA 12 (IP54) units mount through standard knockouts on top or side; side‑mount kits available for limited-top-space installations.
• Controls: Continuous models include filter and distribution kit. Thermostatic and ETC (Electronic Temperature Control) models (separate SKUs) include solenoid valves and digital temperature control.
• Safety & Compliance: All units are UL Listed and CE compliant.
