G521246G802

Overview

The nVent HOFFMAN G521246G802 is a SpectraCool G52 series rack-mounted air conditioner designed for enclosure thermal management. It provides a cooling capacity of 12,000 BTU/hr and operates on 460V AC, 3-phase power with an amperage rating of 3.6/3.5 A. The unit features a stainless steel construction (316SS) suitable for harsh environments, offering NEMA Type 4X and Type 3R protection ratings. Its physical dimensions are 1.34 m in height, 435 mm in width, and 296 mm in depth. The operating temperature range spans from -40 to 55 °C.

Feature Summary

• Constructed from 316 stainless steel for enhanced corrosion resistance in demanding industrial settings.
• Provides NEMA Type 4X and Type 3R protection ratings against dust, water, and corrosion.
• Utilizes mechanical thermostat control for reliable heating and cooling operation.
• Designed for rack mounting within electrical enclosures to maintain optimal internal temperatures.

Applications

• Food and beverage processing environments requiring frequent washdowns
• Pharmaceutical manufacturing facilities with strict hygiene standards
• Industrial enclosures exposed to corrosive atmospheres or high humidity
• Outdoor electrical cabinets requiring robust weather protection

Procurement Notes

Verify the specific voltage configuration (460V 3-phase) matches your facility's power supply before ordering. Confirm that the 316 stainless steel material requirement aligns with your environmental corrosion needs. Ensure the physical dimensions fit within the designated enclosure space. Check for any required accessories such as mounting kits or filters not included in the base unit. Validate that the NEMA Type 4X rating satisfies your site's ingress protection requirements.

Selection Notes

Select this model when high corrosion resistance is critical due to chemical exposure or washdown procedures. The 12,000 BTU/hr capacity suits medium-sized enclosures generating significant heat. The 460V 3-phase input requires compatible industrial power infrastructure. Consider the stainless steel build for longevity in aggressive environments compared to standard painted steel units. Ensure the rack-mount form factor fits the existing enclosure architecture.

Part Context

This unit belongs to the SpectraCool G52 series, which offers advanced corrosion protection. The G521246G802 variant specifically denotes the 12K BTU capacity, 460V 3-phase electrical specification, and 316 stainless steel construction. This series is engineered for durability in harsh industrial conditions where standard aluminum or mild steel units would degrade prematurely.

Replacement Considerations

Direct replacements must match the 12,000 BTU capacity, 460V 3-phase power requirements, and 316 stainless steel construction. Verify dimensional compatibility with the existing enclosure opening. Ensure the replacement unit maintains NEMA Type 4X and Type 3R ratings. Consult manufacturer documentation for updated series equivalents if the G52 line has been superseded.
