Prolink S15 – maximum airflow for small products

For cooling, drying and drainage processes – without compromising small-product conveying. Prolink S15 combines a low pitch of 12.7 mm with a large open area.
It delivers a balanced mix of airflow, product support and robust food conveying while tapping into new applications for small products.

Siegling Prolink S15

Series 15_47% open area
  • Overview
    Christian Reinhard

    “Prolink S15 is engineered for light-duty food applications with high cooling and airflow requirements. The S15-47 GRT has an open area of 47% and a large contact area at the same time. As a result, it supports and conveys even small products reliably. Its durable design also make it a go-to belt for long cooling sections.”

    Christian Reinhard, Global Segment Manager Food & Tobacco

    For cooling and drying processes

    • Prolink drainage

      Maximum airflow. Small openings.

      Uncompromising airflow during conveying

      A large open area boosts airflow during cooling and drying processes. But each opening is still small. Therefore, the belt handles small products well and cuts the risk of losing products in big gaps.

      As a result, the Grid Top surface blends two critical factors in cooling processes: Maximum airflow and dependable product handling.

    • Maximum hygiene with Siegling Prolink plastic modular belts

      Open, easy-to-clean design.

      Hygiene starts in the belt architecture

      Open hinges and eyelet designs facilitate belt cleaning. Fluids and contaminants are easier to remove from critical areas.

      Maintenance is also straightforward. The snap-in system makes inserting and removing the hinge pins simpler. The hard-wearing belt edge also protects sensitive edges.

    • Siegling Prolink plastic modular belts with high load capacity

      Stable on long conveyors

      Developed for non-stop cooling processes

      Prolink S15 pairs a robust design with outstanding belt strength and low elongation in the direction of travel. As a result, it runs smoothly, even on long cooling sections.

      The special underside design operates gently over returns of 12.7 mm in diameter. This feature allows for compact transfer sections within the process.

    Advantages of Prolink S15

    • Exceptional airflow: Open area of 47% helps make cooling and drying processes efficient.
    • Reliable conveying of small products: Small openings guarantee good product support.
    • For long cooling sections: Outstanding belt strength and little elongation encourage smooth tracking.
    • Compact transfers: Designed for returns of 12.7 mm in diameter.
    • Hygienic design: Open hinges and eyelets facilitate cleaning.

    • Straightforward maintenance: The snap-in system makes fitting and removing the hinge pins easier.
    • Flexible belt widths: Small width increments enable a precision fit to the conveyor.
    • RSA option: Small contact area encourages even more airflow to the product.

    What applications is the Prolink plastic modular belt series 15 suitable for?

    Prolink series 15 is a straight plastic modular belt for conveying light-duty products in food applications. Its generous open area really boosts cooling, drying and drainage processes. With a pitch of 12.7 mm, the series is also suitable for compact product transfers.

    Why is the Prolink series 15 ideal for cooling and drying processes?

    The S15-47 GRT and S15-47 RSA have an open area of 47%. This allows air to flow across a large area through the modular belt and reach the product. The open-type pattern also helps drain off fluids.

    Which modular belt is suitable for small items of food and sensitive products?

    The small pitch of 12.7 mm and comparatively small openings help convey small products securely. The biggest opening in the S15-47 GRT and S15-47 RSA is 8.5 mm in diameter. But a large open area of 47% is still maintained.

    What’s the difference between the S15-47 GRT and S15-47 RSA?

    Both belt types have an open area of 47%. The S15-47 GRT has a contact area of 31%. In the S15-47 RSA, the contact area is decreased to 20%. As a result, even less belt surface contacts the product in the RSA version.

    Why are large open areas in plastic modular belts beneficial?

    A large open area boosts airflow and drainage. Series 15 has an open area of 47% and a pattern built for reliable product handling. Which is particularly relevant in cooling and drying processes in the food industry.

    Is Prolink series 15 suitable for small knife edges and tight product transfers?

    Yes. Series 15 is designed for a knife edge with a 12.7 mm diameter. It features a concave belt underside for smooth and gentle product handling over knife edges. As a result, tight transfer points between conveyor segments are possible.

    How does Prolink series 15 enhance hygiene in the food industry?

    The open hinge design facilitates access during cleaning. At the same time, the headless hinge pin simplifies fitting and removal. Therefore, its design is geared to requirements in food applications.

    What materials and temperature ranges are available for Prolink series 15?

    Depending on the belt type, material options include PA, POM and PP. The temperature ranges documented vary depending on the material. In the case of S15-47 GRT in POM the range covers -45 to +90°C, in PA from -40 to +120°C and in PP from +5 to +100 °C. The material chosen depends on the requirements of the application concerned.
