CUH38004

Overview

The CUH38004 is a roof-mounted cooling unit manufactured by nVent Hoffman. It provides 3800W of cooling capacity for electrical enclosures. The unit operates on an AC voltage range of 400-460V at 50 Hz. Constructed from mild steel, it features an IP54 ingress protection rating. The design utilizes an air-to-air heat exchange mechanism to dissipate internal heat without introducing external contaminants into the enclosure.

Feature Summary

• Utilizes an air-to-air heat exchange system to maintain internal temperature stability.
• Constructed from mild steel with an IP54 rated enclosure for environmental protection.
• Designed for direct mounting on the roof of industrial electrical cabinets.

Applications

• Cooling of industrial electrical control panels
• Thermal management of automation equipment enclosures
• Protection of sensitive electronic components in outdoor or harsh environments

Procurement Notes

Verify that the supply voltage matches the required 400-460V AC specification before installation. Confirm that the mounting surface can support the unit's weight and dimensions. Ensure the enclosure has adequate structural integrity for roof mounting. Check local regulations regarding electrical connections and grounding requirements for outdoor-rated equipment.

Selection Notes

Select this model when a cooling capacity of approximately 3800W is required for large enclosures. Ensure the ambient temperature conditions do not exceed the unit's operational limits. Verify that the available power supply aligns with the 400-460V requirement. Consider the IP54 rating suitability for the specific installation environment compared to higher protection ratings if necessary.

Part Context

This component belongs to the Hoffman Enclosures climate control product line, specifically designed for thermal management solutions. It serves as an alternative to internal fan filters or water chillers for applications requiring robust, external heat dissipation. The product is part of the broader nVent Hoffman portfolio of industrial enclosure accessories.

Replacement Considerations

Consult official nVent Hoffman documentation for cross-reference data. Verify compatibility with existing mounting holes and electrical connections when substituting similar models. Ensure the replacement unit meets or exceeds the required 3800W cooling capacity and voltage specifications.
