Feature Summary

• Provides sealed enclosure protection against corrosive outdoor environments
• Designed for side mounting applications within industrial enclosures
• Constructed from durable steel material for structural integrity

Applications

• Outdoor industrial control panels requiring corrosion resistance
• Harsh environment equipment housing needing thermal management
• Enclosures rated for NEMA 3R, 4, or 12 compliance

Procurement Notes

Verify the specific voltage and frequency requirements match your site infrastructure before ordering. Confirm that the physical dimensions fit within the designated enclosure space. Ensure the power supply provides adequate amperage for the 13.5 A draw. Check local electrical codes regarding the required NEMA 5-20 plug connection type for safe installation.

Selection Notes

Select this model when high cooling capacity is needed for medium to full-sized enclosures in outdoor settings. Consider the side-mount configuration if front access is restricted. Evaluate the 4000 BTU/hr output against the internal heat load calculations. Verify that the steel construction aligns with environmental exposure levels compared to aluminum alternatives.

Part Context

This unit belongs to the nVent HOFFMAN ProAir™ series, which specializes in thermal management for electronic enclosures. The ProAir line addresses challenges in harsh environments where standard air conditioners may fail due to corrosion or extreme temperatures. This specific model targets outdoor installations requiring robust sealing and significant cooling power.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When replacing, ensure the new unit matches the 115V AC input, 4000 BTU/hr capacity, and side-mounting footprint. Verify compatibility with existing NEMA-rated enclosures.
