G521226G151

Overview

The Hoffman Enclosures Inc. G521226G151 is a SpectraCool indoor/outdoor enclosure air conditioner designed for thermal management in industrial environments. It operates on a single-phase AC power supply of 208 to 230 V at 50/60 Hz, drawing approximately 9.1 to 10.9 A. The unit provides a cooling capacity of 12,000 BTU/hr with a wattage of 3,500 W. Constructed from SS Type 304 stainless steel, it features a side-mount design and measures 53 inches in height. The device offers protection ratings of NEMA 3R, 4, 12, and IP56, ensuring durability against environmental factors.

Feature Summary

• Constructed from SS Type 304 stainless steel for corrosion resistance
• Provides NEMA Type 4X, 3R, and IP56 protection ratings
• Equipped with basic mechanical thermostat control
• Designed for both indoor and outdoor installation

Applications

• Thermal management for industrial electrical enclosures
• Cooling applications in outdoor environments requiring NEMA 3R or 4X compliance
• Indoor rack thermal management systems
• Protection of sensitive electronic components in harsh conditions

Procurement Notes

Verify the specific voltage requirement (208V vs 230V) and frequency (50Hz vs 60Hz) compatibility with your facility's power supply before ordering. Confirm that the side-mount configuration fits the intended enclosure space. Ensure the SS Type 304 material meets your corrosion resistance standards. Check if the NCNR status applies to your purchase order to avoid return issues.

Selection Notes

Select this model when high-capacity cooling (12,000 BTU/hr) is required for large enclosures exposed to outdoor elements. The stainless steel construction is critical for corrosive environments where aluminum units would fail. Verify that the 230V single-phase input matches available power infrastructure. Consider the 53-inch height dimension during spatial planning to ensure adequate clearance for airflow and maintenance access.

Part Context

This unit belongs to the SpectraCool series by Hoffman Enclosures Inc., specialized for robust thermal control. The G52 prefix indicates the series, while the suffix specifies voltage, capacity, and material variations. It serves as a direct replacement for older Hoffman models requiring similar cooling output and environmental protection levels in industrial settings.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify dimensional compatibility and mounting hole patterns when considering alternative brands. Ensure the replacement unit maintains the same NEMA/IP rating and cooling capacity to prevent thermal failure.
