Explosion-Proof Revolving Unit (XRU): The "XRU" is a copper-free aluminum cast enclosure that completely contains the slip ring assembly. It is available in 1.5", 2.5", and 3" O.D. shaft sizes. The cover threads onto the base (entrance ring) with an "O" ring seal between. Incoming wiring enters through a 1" NPT hub cast into side of the entrance ring. The shaft runs on double-ball bearings. The unit can be mounted using the standard shaft provided - or Conductix can design a special mounting arrangement.
Sealing: NEMA 4 (water and dust tight) and NEMA 9 (Explosion-Proof)
Max. Speed: 125 rpm (1.5" bore); higher speeds attainable with optional carriage ball bearings.
Explosion-Proof Swivel Unit (XSU) The "XSU" is a rugged cast iron enclosure with painted finish that completely encloses the slip ring. Available in single and double housing configurations with 1.5" O.D. shaft. Removeable doors are provided to access internal wiring.
Explosion-Proof Swivel Unit with Air Pass This version of the "XSU" includes a pass-through style shaft to accommodate air or fluids. An explosion-proof junction box is provided to house incoming wire leads.
Special Explosion-Proof Enclosure Options:
Heater strips to reduce internal condensation
Explosion-proof breather drain to reduce internal condensation
Special flange designs to match host equipment
