The Tigerflex Voltbuster heavy walled thermoplastic hose from Kuriyama of America Inc., Schaumburg, Ill., fulfilled a customer request for a thermoplastic hose that had static-dissipative properties on par with metal- and carbon black-filled rubber hoses. Kuriyama will showcase the hose at NPE 2015 (March 23-27, Orlando) in booth 31118, South Hall level 1.
When the static generated inside a hose overloads the dielectric strength of the hose tube, “hose arcing” can occur, resulting in worker injury or the ignition of a dust cloud. Kuriyama notes that the elimination of all potential dust-cloud ignition sources is a safety imperative for any facility processing potentially explosive materials.
The Voltbuster thermoplastic hose features a wall thickness sufficient to support the double-layer charge needed to produce propagating brush discharges, while simultaneously possessing a charge decay time constant of less than one second, thereby eliminating the risk of such discharges.
Third party safety testing firm, Chilworth Technology, independently validated the dissipative properties of the Voltbuster hose, according to Kuriyama, concluding that a properly grounded Voltbuster will not retain an electrostatic charge that would be sufficient to create propagating brush discharges.
The Voltbuster is designed for use at any facility handling powders, pellets, or other granular materials, offering a comparably lightweight and flexible alternative to metal and rubber hoses and easing handling while aiding worker safety.
Voltbuster is constructed from abrasion-resistant food-grade polyurethane, which remains flexible at sub-zero temperatures, provides for quieter operation than metal hoses, ensures the purity of the transferred materials and allows for visual confirmation of material flow.
