CR290246G401

Overview

The Hoffman Enclosures Inc. CR290246G401 is a Spectracool ProAir enclosure air conditioner designed for industrial environments. It provides 2700 Btu/hr cooling capacity and operates on 460 VAC at 50/60 Hz, drawing 1.9 to 2.0 A. The unit is constructed from mild steel with a gray finish and meets NEMA 3R, 4, and 12 protection standards. Its physical dimensions are approximately 20 inches in length, 11 inches in width, and 8.63 inches in depth, weighing 130 lbs.

Feature Summary

• Provides active thermal management for electrical enclosures using refrigerant-based cooling technology.
• Constructed from mild steel to ensure durability and resistance against environmental contaminants.
• Engineered to maintain internal temperature stability under varying ambient conditions.

Applications

• Cooling electrical control panels requiring NEMA 3R, 4, or 12 ratings
• Industrial machinery enclosures exposed to dust, dirt, or moisture
• Outdoor equipment housings needing reliable heat dissipation

Procurement Notes

Verify the specific voltage requirement of 460 VAC matches your facility's power supply before ordering. Confirm that the NEMA 3R/4/12 rating aligns with your environmental exposure needs. Ensure the mounting space accommodates the unit's dimensions of 20 x 11 x 8.63 inches. Check for any required accessories such as continuous hinge clamps or mounting hardware not included in the base unit.

Selection Notes

Select this model when passive ventilation is insufficient for heat loads exceeding natural convection limits. The 2700 Btu/hr capacity suits moderate-sized enclosures with significant internal heat generation. Consider the 460 VAC input if standard low-voltage options are unavailable. Evaluate the weight and structural support requirements due to the unit's 130 lb mass.

Part Context

This component belongs to the nVent HOFFMAN Spectracool ProAir series, which specializes in high-efficiency enclosure cooling solutions. The CR29-0246 designation indicates its specific cooling class and form factor within the product line. It serves as an alternative to fan-and-filter assemblies in harsher industrial settings where sealed cooling is necessary.

Replacement Considerations

Direct substitutes may include other models within the Spectracool ProAir family with similar Btu/hr ratings. Verify compatibility with existing enclosure cutouts and electrical connections when swapping units.
