NORRES AIRDUC® profile hoses have a spring steel wire firmly
embedded in the wall and are spiral-welded. They have very smooth
interior surfaces, high axial stiffness combined with good
flexibility and are lightweight in
relation to comparable rubber hoses.
We can adapt the design and characteristics of the hose to meet your
specific requirements. This increases the benefit to the customer,
creates added value and often reduces costs. Let us know what we can
do for you!
Welding:
Coherent, secure bonding
Gas and liquid tight
Partial or complete colouring to meet customer specifications
Long welding seam for greater process and operational reliability
Extruded profile hose with a high delivery rate:
High smoothness of the interior hose surface
→ less deposition of the delivered material
→ gentler material delivery
Section shape is optimized for flow
→ low pressure loss
→ reduction of blower power requirements
→ lower operating costs
Reinforced wall at the primary points of wear
Optimized design:
High axial stiffness
Very flexible
Folds evenly
Steel wire:
Spring steel wire firmly embedded in the wall
No softening of the reinforcement at high temperatures (in contrast to
full plastic hoses)
Electrically dischargeable by grounding the wire (see the
technical appendix)
