AIRDUC®
(incl. TIMBERDUC® 533 – 534)

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.

1. 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
2. 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
3. Optimized design
High axial stiffness
Very flexible
Folds evenly
4. 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
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!

PROTAPE®
PROTAPE®
(incl. TIMBERDUC® 531 – 532)

NORRES PROTAPE® film hoses have a spring steel wire embedded in the wall and are welded from spiral tape material. They are extremely flexible, compressible and lightweight.

1. Welding
Optimal quality due to a patented welding procedure
Coherent, secure bonding
Gas and liquid tight
Can be partially or completely coloured to meet customer specifications
2. Extruded film tape
Optimized for flow
Possible to reinforce at the primary points of wear
3. Optimized design

Extremely light and flexible
Folds evenly
4. Steel wire
No PVC-coated wires used
No softening of the reinforcement at high temperatures (in contrast to full plastic hoses)
Electrically dischargeable by grounding the wire
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!

PROTAPE®
Construction PROTAPE®
PROTAPE® MEMORY
NORRES PROTAPE® MEMORY hoses have a special reinforcement on the outside of the hose wall and are welded from spiral tape material. They are extremely flexible and lightweight. Depending on the type, the entire construction is semi-crush resistant or crush resistant.

1. Welding
Coherent, secure bonding
Gas and liquid tight
2. Optimized design
High vacuum performance due to special outer folding
Extremely light and flexible
3. Special reinforcement
Special design provides limited or long-lasting resistance to crushing
Optional partial colouring to meet customer specifications
External protection against abrasion

NORPLAST®
NORPLAST® without inliner
NORRES NORPLAST® full plastic hoses have a hard plastic spiral firmly embedded in the wall and are welded from spiral material. They have very smooth interior surfaces and are usually lighter than hoses reinforced with steel wire, though at the same time less flexible.

1. Welding
Coherent, secure bonding
Gas and liquid-tight
Optional partial or complete colouring to meet customer specifications
2. Hard plastic spiral
Hard plastic spiral firmly embedded in the wall
Spiral is securely and uniformly positioned in the hose wall
3. Stranded earthing wire (if provided)
Limitedly capable of discharge by earthing the stranded wire
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!

CP
Clamp Profile
NORRES CP clamp profile hoses (CP = “clamp profile”) are based on a design that offers numerous product benefits particularly under high stress. Single-layered, double-layered or multi-layered strip materials are combined in a clamping profile, with an embedded wire to prevent slippage. These hoses are flexible, compressible, have high external abrasion resistance and can also be extremely resistant to chemicals and/or heat.

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!

CP
Single-layer
Abrasion resistance due to the external clamping profile

Especially stable clamping profile
The drop-shaped form ensures a high geometrical moment of inertia
→ high compression strength
→ high vacuum load capacity
Round clamping profile
→ good, even distribution of the clamping force
→ no spot stress peaks
→ increased impermeability
Rounded clamping profile ends
Protective baffling of the webbing/film materials
High dynamic load capacity
High overpressure load capacity
Construction CP Single-layer
Multi-layer
Multi-layered wall design can be selected
Selective adjustment of the product properties
Improved impermeability
Thermal insulation
Sound insulation
Construction CP Multi-layer
CP HYP 450 PROTECT, CP ARAMID 461 PROTECT
External protective profile
Made of elastic material
Provides impact and abrasion resistance
Available in any colour
Specially developed, protected geometry
Firm clamping protects against slippage
Beading at the end of the section offers additional protection against slippage

BARDUC®
