G280646G101

Overview

The nVent HOFFMAN G280646G101 is a SpectraCool indoor/outdoor enclosure air conditioner designed for thermal management in industrial environments. It provides a cooling capacity of 6000 Btu/hr and operates on a 400/460 V AC, 3-phase power supply at 50/60 Hz. The unit draws 1.7/1.9 A and features a NEMA 3R/4/12/IP56 rating for environmental protection. Constructed from steel with a light gray finish, its physical dimensions are 28.55 inches in height, 16.97 inches in width, and 10.10 inches in depth.

Feature Summary

• Provides active thermal regulation for electronic enclosures using compressor-based cooling technology.
• Constructed with galvanized sheet metal cover to ensure durability in rugged factory and outdoor settings.
• Equipped with a basic mechanical thermostat for straightforward temperature control operations.

Applications

• Thermal management for industrial control panels requiring NEMA 3R/4/12 protection
• Cooling of sensitive electronics in outdoor or harsh factory environments
• Enclosure climate control for telecommunications or utility infrastructure

Procurement Notes

Verify the specific voltage configuration (400V vs 460V) matches your site power infrastructure before ordering. Confirm that the 3-phase requirement aligns with available electrical sources. Ensure the mounting cutout dimensions accommodate the 28.55 x 16.97 inch footprint. Check for non-cancelable, non-returnable status as this item may be drop-ship only.

Selection Notes

Select this model when high-capacity cooling (6000 Btu/hr) is required for large enclosures in demanding environments. The IP56/NEMA 4 rating makes it suitable for washdown areas or dusty locations. Consider the physical size constraints carefully, as the unit is relatively large compared to lower-capacity alternatives. Ensure adequate clearance around the unit for airflow and maintenance access.

Part Context

This unit belongs to the Hoffman SpectraCool series, which specializes in enclosure thermal management solutions. The G28 series typically denotes specific form factors and capacities within the Hoffman product line. These units are engineered to maintain optimal operating temperatures for enclosed equipment, preventing overheating and extending component lifespan in industrial applications.

Replacement Considerations

Direct replacements must match the 6000 Btu/hr capacity and 460V 3-phase electrical specifications. Verify dimensional compatibility with existing enclosure cutouts. Units from other manufacturers require careful evaluation of NEMA/IP ratings and mounting configurations to ensure equivalent environmental protection and fit.
