Overview

The nVent SpectraCool Outdoor Air Conditioner (G521226G151) delivers 12,000 BTU/hr (3,500W) of cooling for medium-sized enclosures in harsh outdoor environments. Designed for Type 4X stainless steel enclosures, this unit operates on 208-230V AC single-phase power with a dual A-B power feed. Its closed-loop cooling system separates recirculated air from ambient airflow, ensuring clean, filtered cooling without external contaminants. Key features include a reusable aluminum mesh filter (cleanable and invertible), EMI/RFI noise suppression, and a condensate management system that evaporates moisture for maintenance-free operation. The unit’s dimensions are 52.69 in (1338.4 mm) height, 17.12 in (435 mm) width, and 11.66 in (296.1 mm) depth, with a brushed SS304 housing for corrosion resistance. It supports front cover access for easy servicing and is rated for IP56 internal and IP34 external loops. Ideal for telecommunications shelters, data centers, and industrial control panels, the SpectraCool G52 ensures reliable thermal management in extreme conditions.
