G521246G100

Overview

The nVent Hoffman G521246G100 is a Spectracool series outdoor sealed enclosure air conditioner designed for demanding environments. It provides 12,000 BTU/hr cooling capacity using an energy-efficient rotary compressor. The unit operates on 3-phase power at 400 to 460 VAC and 50/60 Hz, with a maximum current rating of 3.5 A. It features a filterless design and includes a cleanable aluminum mesh filter to protect coils in dirty conditions. The enclosure offers protection ratings including NEMA Type 4, IP65, and IP66, suitable for indoor and outdoor use.

Feature Summary

• Filterless design combined with a cleanable reusable aluminum mesh filter for coil protection
• Energy-efficient rotary compressor technology
• Sealed construction suitable for harsh and dirty environments

Applications

• Outdoor industrial enclosure cooling
• Enclosures exposed to dust or particulate matter
• Harsh environmental control applications requiring high ingress protection

Procurement Notes

Verify the specific voltage configuration (400-460 VAC) and phase requirements against site electrical infrastructure before procurement. Confirm that the NEMA Type 4/IP65/IP66 ratings align with the intended installation environment's exposure levels. Ensure the 3.5 A current draw is supported by the available circuit capacity. Check for any required mounting hardware compatibility with the specified dimensions.

Selection Notes

Select this model when high cooling capacity is needed for large enclosures in outdoor or dirty settings. The filterless design reduces maintenance frequency compared to traditional filtered units. Consider the 3-phase power requirement as a constraint for sites only offering single-phase supply. The robust corrosion protection and sealed design make it suitable for areas with significant environmental stressors.

Part Context

This unit belongs to the nVent Hoffman Spectracool G52 series, which focuses on reliable enclosure climate control. The G521246G100 variant specifically denotes the outdoor model without heating capability, distinguishing it from heat pump versions like the G521246G151. It is part of a lineup engineered for durability and ease of installation in industrial automation and infrastructure sectors.

Replacement Considerations

Direct replacements may include other models within the Spectracool G52 series with matching 12,000 BTU capacity and 3-phase power specifications. Verify dimensional compatibility and mounting hole patterns if substituting with different brands. Ensure the replacement unit maintains equivalent NEMA and IP protection ratings for the application environment.
