Applications
Tri-Flex belts are frequently used in installations where food is cooled or heated in a controlled manner. Typical processes are:

Cooling
Freezing
Pasteurize
Smoking
Cooking

Thanks to their flexible construction, these belts are ideal for spiral tower installations, such as freezing and cooling towers. They also perform well in straight transport lines, for example when shock-freezing with liquid nitrogen.

Benefits

Cornering possible: flexible design allows turning in tight radii
Widely applicable: suitable for both spiral and straight systems
Hygienic design: optimal for food processing
Precision production: constant finish for reliable running and long life
Maintenance advantage: belts can be reversed for longer life‍
Customization: fully tailored to your installation, including strength calculation and stress measurement by means of a data logger

Options

Spiral deck with variable pitch and wire thickness
Unilateral weaving with a small pitch (< 4.25 mm)
Various stainless steel material combinations
Raised side links for specific product guidance
Various support systems: radius strips (spiral) or herringbone pattern (straight)
Custom welding and finishing options for optimal performance in your installation

Drives
Tri-Flex tires are powered by a combination of drum friction and specially developed drive wheels.

Drive wheels: in-house produced, fully customized
- Recommended number of teeth: 12 — 24
- Width: usually 45 — 55 mm (customer-specific possible)
- Materials: POM, PE1000, 1.4305, 1.0503
- With or without keyway/mortise
Optimal run: wide wrap angle (±180°) for maximum grip
Placement: on the drive shaft and possibly on axles for direction correction‍
Coordination is crucial: right balance between drum speed and gear drive (overdrive) for trouble-free operation

FAQs

What is a Tri-Flex conveyor belt and what is it suitable for?

The Tri-Flex conveyor belt from Tribelt is specially designed for industrial processes with curves and height differences. This stainless steel belt is widely used in freezing and cooling towers, pasteurizers, smoke systems and cooking lines in the food industry.

What temperatures can a Tri-Flex conveyor belt handle?

Depending on the version, the Tri-Flex conveyor belt operates from -50 °C to +400 °C, making it suitable for cryogenic processes such as shock freezing with liquid nitrogen, but also for high-temperature applications such as baking or smoking.

What materials does the Tri-Flex conveyor belt come in?

Tribelt supplies the Tri-Flex conveyor belt in durable stainless steel materials, such as 1.4301, 1.4310, 1.4404 and 1.4401. These materials offer optimal corrosion resistance, hygiene and longevity.

What are the benefits of a Tri-Flex conveyor belt?

The Tri-Flex conveyor belt offers:

Design freedom: straight and curved lines in one
High load-bearing capacity
Hygienic construction without protruding wire ends
Temperature resistance up to 400 °C
Reversible strap for longer life

In addition, Tribelt offers engineering advice and built-in support on location.

‍

Is a Tri-Flex conveyor belt customized for my production line?

Yes. Each Tri-Flex conveyor belt is custom-made, including bandwidth, wire thickness, spiral pitch, material and drive system. This way, the stainless steel belt fits perfectly to your freezing, cooling or thermal installation.
