Maximum Corrosion Resistance and Electrical Isolation
Hoffman non-metallic enclosures address applications where metallic materials simply cannot perform. Chemical processing, water treatment, pulp and paper, mining, and other industries with highly corrosive atmospheres rely on fiberglass and polycarbonate enclosures for long-term equipment protection without the maintenance concerns of metal enclosures.
Fiberglass Reinforced Polyester (FRP)
Hoffman fiberglass enclosures are manufactured from fiberglass reinforced polyester (FRP), providing exceptional properties for demanding environments:
- Corrosion Immunity - Unlike metals, FRP cannot rust or corrode. Withstands acids, alkalis, salts, and most industrial chemicals.
- Electrical Isolation - Non-conductive material eliminates shock hazards and prevents ground faults. Ideal for applications near high-voltage equipment.
- UV Resistance - Standard UV-stabilized formulation withstands outdoor exposure without degradation.
- Impact Strength - Glass fiber reinforcement provides excellent resistance to physical damage.
- Lightweight - Significantly lighter than equivalent steel enclosures, reducing installation effort and structural requirements.
Polycarbonate Enclosures
For applications requiring transparency or extreme impact resistance, Hoffman offers polycarbonate enclosures. Clear polycarbonate covers allow visual inspection of components without opening the enclosure. The material's exceptional toughness resists breakage even under severe impact.
NEMA Ratings
Hoffman non-metallic enclosures are available with NEMA 4X and other ratings suitable for:
- Indoor or outdoor installation
- Washdown environments
- Corrosive atmospheres
- Areas requiring electrical isolation
Industry Applications
Non-metallic enclosures excel in applications where their unique properties provide advantages over metallic alternatives:
- Water/Wastewater Treatment - Chemical feed systems, instrumentation, pump controls
- Chemical Processing - Process controls, analytical equipment, motor starters
- Pulp & Paper - Bleaching area controls, chemical handling, process instrumentation
- Mining - Underground controls, processing equipment, ventilation systems
- Food Processing - Washdown areas, refrigerated environments, processing controls
- Outdoor/Utility - Traffic controls, telecommunications, remote monitoring
