G280446G052

Overview

The Hoffman Enclosures G280446G052 is a 4000 BTU enclosure air conditioner designed for industrial environments. It operates on 460V power with support for both 50 Hz and 60 Hz frequencies in a three-phase configuration. The unit provides cooling and heating capabilities, featuring washdown-resistant construction suitable for harsh conditions. It is rated for Type 4X enclosures, ensuring protection against corrosion and water ingress.

Feature Summary

• Provides simultaneous cooling and heating functionality for precise thermal management
• Constructed with washdown-resistant materials for durability in demanding environments
• Designed specifically for installation within Type 4X electrical enclosures

Applications

• Industrial control panels requiring corrosion resistance
• Outdoor electrical installations exposed to washdown procedures
• Enclosures housing sensitive electronics needing active temperature regulation

Procurement Notes

Verify the specific voltage and phase requirements (460V, 3-phase) match your facility's power infrastructure before procurement. Confirm that the 4000 BTU capacity aligns with the heat load calculations of the target enclosure size. Ensure the mounting dimensions fit the designated NEMA Type 4X enclosure model. Check for any required accessories or mounting kits sold separately by the manufacturer.

Selection Notes

Select this model when high corrosion resistance is critical due to the Type 4X rating. It is appropriate for applications where ambient temperatures fluctuate significantly, given its heating capability. Consider the physical footprint and weight constraints of the enclosure. Evaluate if the 460V input voltage is compatible with existing electrical systems to avoid the need for additional transformers or converters.

Part Context

This component belongs to the Hoffman G28 series of enclosure climate control units. These units are engineered to maintain optimal internal temperatures within electrical cabinets. The series typically includes various BTU ratings and voltage options to suit different enclosure sizes and environmental demands. Hoffman, now part of nVent, specializes in robust enclosure solutions for industrial automation and process control sectors.

Replacement Considerations

Direct replacements must match the 4000 BTU capacity, 460V 3-phase power requirement, and Type 4X rating. Verify dimensional compatibility with the existing enclosure cutout. Alternative models from the same manufacturer may offer different voltage inputs or BTU outputs but must meet the same environmental protection standards.
