Overview

The nVent Hoffman Easy Swap Adaptor Plenum, SKU PLKG28, provides a direct replacement solution for end-of-life or damaged industrial air conditioners. Designed to seamlessly integrate newer nVent Hoffman Genesis G28 series air conditioners into existing enclosure cutouts, this adaptor plenum eliminates the need for costly and time-consuming enclosure modifications. Its key benefit is the 'no modification' design, precisely matching the cutout and mounting hole patterns of the air conditioner being replaced, significantly reducing installation time and labor. Unlike a simple flat plate, the plenum design optimizes airflow, preventing obstruction of the new unit's intake and outtake vents and ensuring efficient cooling. Constructed from durable 18-gauge steel and finished in light gray to match standard nVent Hoffman units, the PLKG28 includes a gasket for a secure seal. When properly installed on a Type 12 enclosure, it helps maintain NEMA Type 12 and IP 54 ratings, safeguarding internal components from dust and water ingress. This adaptor is ideal for facilities upgrading thermal management systems without compromising enclosure integrity or incurring extensive retrofitting expenses. Applications include replacing failed AC units, upgrading to Genesis G28 series, minimizing downtime, and maintaining environmental protection ratings.
  • No modification of the enclosure required - designed to match the enclosure cut-out and mounting holes of the air conditioner being replaced
  • Plenum design allows for optimum air flow (vs. a flat plate that can block the air intake and air outtake left by the older air conditioner)
  • Gasket included
  • 18 gauge steel
  • Includes gasket for a secure seal
  • Light gray finish matches standard nVent Hoffman AC units
