Corrosion, Dust & Moisture Proof Enclosures

nVent HOFFMAN enclosures protect your valuable equipment from many adverse conditions because they are manufactured from hot compression molded Fiberglass Reinforced Polyester (FRP).

FRP is a complex composite material consisting of a polyester resin base with organic fillers to facilitate flow and to obtain special physical characteristics such as UV resistance, halogen-free and self-extinguishing properties. Additional additives are used to provide for proper consistency and pigmentation of the resin base.

Glass fibers, which make up 25 percent of the overall compound, are sandwiched between two layers of the polyester resin and are impregnated into the resin base by an elaborate roller system. This process produces a very uniform, high strength material.

nVent HOFFMAN utilizes the most advanced process for molding its enclosures. Our hot compression molding process provides a better flow of material into tight corner areas than cold molding process. This produces a stronger end product, allowing the glass fibers to run in every direction. Injection molding only allows the glass fibers to run in a single direction.

nVent HOFFMAN enclosures are lightweight, durable, watertight and non-corroding. They are a superior alternative to metal enclosures. Our track record for producing these quality products spans more than 40 years.
