As such, many food manufacturers are beginning to make the switch to enclosures made of thermoplastic or composite fiberglass NEMA 4X construction because the water, caustic, acid, and bleach that are regularly used during the cleaning process often damage stainless steel enclosure options.
Thermoplastic, such as polycarbonate, polyester, ABS and PVC, provide a degree of corrosion protection beyond painted carbon and stainless steel. Composite fiberglass, for example, is not susceptible to rust or other forms of oxidation. Composite fiberglass enclosures also offer excellent chemical resistance to halogens such as chlorine and fluorine.
A major butter processing plant in Michigan recently made the switch to fiberglass composite enclosures after the continued failure of other enclosure options in this corrosive environment. The facility also benefited from other key benefits of composite fiberglass enclosures such as ease of modification and lightweight handling during installations. After reviewing several composite enclosure manufacturers the electrical engineers at the plant chose Stahlin Non-Metallic Enclosures over its competition due to the high quality of their product and its unique implementation applications.
The fiberglass-reinforced plastic enclosures withstand extreme conditions, are minimally affected by impact, and offer temperature, moisture, and greater overall corrosion resistance against numerous environmental challenges. Fiberglass-reinforced plastic enclosures are more reliable; reducing costs because of their longer lifespan. The plastic, fiberglass-reinforced enclosures offer multiple additional benefits: they are lighter in weight, decrease installation challenges, and are easily modified for use in custom projects.
