ULTRX Enclosure Accessories
nVent Hoffman ULTRX fiberglass enclosures are high-impact resistant and have temperature and chemical resistant qualities. Fiberglass is easily drilled, punched, sawed and the exterior surface can be painted to enhance UV protection.
nVent Hoffman ULTRX Panels are available in 12 gauge steel or ¾ inch wood. Wood panels are supplied with the enclosure. Steel panels require the Panel Bracket Kit to mount to the enclosure. Panel Bracket Kits permit panel adjustment from front to rear and mount on integrally molded body rails.
nVent Hoffman Swing-Out Panels are front-mounted and compliment window-door ULTRX fiberglass enclosures. They are suited for applications requiring a display of dials, gauges or any type of control equipment monitor. Swing Frames provide 19 inch rack-mounting capabilities with U-Style mounting hole pattern. The quarter-turn latch has a 100 degree swing. The swing frame maintains the enclosure rating if properly installed.
Non-Metallic Enclosure Types
Characteristics of non-metallic enclosures:
- NEMA 4x rating for outdoor use providing chemical resistance and protection from dust, debris, water and rain.
- High insulation value, which provides insulation from cold and hot temperatures, but does not dissipate heat from inside the enclosure.
- Non-conductive, meaning components cannot be grounded to the enclosure, but it still provides the same security and tamper resistance levels as metallic enclosures when properly locked.
Types of non-metallic enclosures:
Fiberglass. A thermoset polyester material reinforced with glass fibers. It is the most widely used non-metallic material in the industry. It has high impact strength and rigidity (dimensional stability), a superior working temperature range (-31˚F to 300˚F), excellent electrical properties, moisture and chemical resistance, as well as being cost effective.
Polycarbonate. High-performance thermoplastic resin processed by injection molding or sheet extrusion. It has superior impact resistance, good rigidity (dimensional stability), an extended temperature range (-31˚F to 180˚F), excellent electrical properties, fire retention, UV stability and corrosion resistance in some acidic surroundings. It is not suitable for environments with strong alkalis and organic solvents.
ABS or ABS bends. Acrylonitrile Butadiene Styrene is a common thermoplastic polymer processed by injection molding. It has high impact resistance, but less impact resistance in cold weather compared to polycarbonate, excellent electrical properties, superior chemical and moisture resistance, but a narrower temperature range than fiberglass (-40˚F to 248˚F).
Polyester. High-performance unfilled thermal plastic processed by injection molding. It has high impact resistance, but less impact resistance in cold weather than polycarbonate, excellent electrical properties, superior chemical and moisture resistance, but a narrower temperature range than fiberglass (-40˚F to 248˚F).
