G280446G700

Overview

The Hoffman G280446G700 is a SpectraCool series enclosure air conditioner designed for indoor and outdoor use. It provides a nominal cooling capacity of 4000 BTU/hr (1172 Watts) with a power supply requirement of 400-460 VAC, 3-phase. The unit features Advanced Corrosion Protection Level 1 on painted galvanized steel construction. Physical dimensions are approximately 28.59 inches in length, 17.01 inches in height, and 11.18 inches in depth. It utilizes a mechanical thermostat for control and operates at an amperage rating of 1.7/1.9 A.

Feature Summary

• Advanced Corrosion Protection Level 1 coating for durability in harsh environments
• Type 4 rated design suitable for both indoor and outdoor installation
• Mechanical thermostat control for reliable temperature regulation
• Galvanized steel construction with painted finish

Applications

• Enclosures exposed to harsh, corrosive chemical elements
• Industrial rack thermal management systems
• Outdoor electrical cabinet climate control
• Indoor industrial equipment protection

Procurement Notes

Verify the specific voltage configuration matches the site power supply, as this model requires 400-460 VAC 3-phase input. Confirm that the required corrosion protection level aligns with the environmental conditions, as this unit specifies Advanced Corrosion Protection Level 1. Ensure physical mounting dimensions accommodate the specified depth and width constraints within the target enclosure space.

Selection Notes

Select this model when high cooling capacity is needed for larger enclosures in corrosive environments. The 4000 BTU/hr output supports significant heat loads. The 3-phase power requirement necessitates compatible facility infrastructure. Consider the Type 4 rating if the installation location is subject to water or dust ingress. Verify that the mechanical thermostat meets the precision requirements of the application.

Part Context

This unit belongs to the nVent Hoffman SpectraCool G28 series, which offers various cooling capacities for rack and panel applications. The G28 series is engineered for robust thermal management in industrial settings. This specific part number denotes the 4000 BTU variant with specialized corrosion-resistant finishes, distinguishing it from standard stainless steel or non-corrosion-protected models within the broader product line.
