Spiral Hose Poly Urethane Antistatic Flat Food Contact Compliant Carbon wire
Super Flexible & Telescopic

Flexible hose/ducting for transport of explosion hazardous abrasive dust, powder, fibers, air, gasses, and liquids. This hose does not contain any metallic spiral, a fiber wire is sealed in instead.

  • This fiber wire can be grounded / earthed.
  • This hose is tested to be suitable for direct contact with food and pharmaceutical products, such as sugar, milk powder, rice, cereals, coffee, chocolate, grains, tea, flour, frozen foods.
  • This hose is suitable for explosion hazardous environments due to its electrostatic conductive properties.
  • The hose can be used for extraction arms, long distances to connect tubing machinery or components.

The Poly Urethane material is suitable for contact with food according to American and European food contact regulations.

Overpressure and under pressure are recommended threshold operating values, products can be subject to higher loads upon request. The bending radius is measured through the inside of the hose arch. The right to make technical modifications is reserved. All values determined at 20°C and are approximate data.

* Spiral AS Flat with 2 stainless steel reinforcement rings and 2 Poly Ethylene reinforcement rings, which will run through a metal detector, under negative pressure.

Production Methods used

  • Welding
  • HF high frequency welding
    • Welding the material and cooling it down under compression with Radio Frequency to make the TPU material flow nearly seamless to form a uniform thickness with the original material wall thickness.
  • Heat contact – with silver alloy heating element
    • Welds are welded surface to surface after which the weld are compressed while cooling.
  • Hot air – hot filtered and conditioned contaminent-, oil- and grease- free compressed air
