Hofeimer Retention System for Plastic Granulate – 70 µm Complete Set
Pinpoint Protection for Yard Drains According to EU Regulation 2025/2365
Wherever plastic granulate is processed or stored, yard drains are critical interfaces with the environment. Our Hofeimer set with 70 µm filter fineness was specially developed for pinpoint drainage on industrial sites. It actively supports industrial companies in meeting the strict requirements of EU Regulation 2025/2365 and stopping granulate emissions (microplastics) directly at the source. As a specialized retention system for plastic granulate, this set offers a legally compliant solution for modern industrial standards.
This ready-to-install set is the ideal technical solution for companies that need to demonstrate, as part of Operation Clean Sweep audits, that their drainage systems are secured against granulate losses. While standard slotted buckets only catch coarse dirt, our specialized fabric reliably retains even the finest abrasion.
Optimized for production-adjacent drainage
The Hofeimer is preferably used where maximum safety is required in a confined space. It is a central component for a clean infrastructure in industries such as Energy & Environment as well as Chemistry & Raw Materials:
- Pinpoint drainage in production halls and storage areas
- Yard drains near grinding material plants
- Cleaning areas for logistics equipment (industry focus: Transport & Logistics)
- Securing secondary drains on industrial sites in Civil Engineering & Landscaping
Technology without Compromise: The Winkler Sealing System
A retention system is only as good as its seal. The "rushing through" of particles past the bucket wall is prevented in our system by a mechanical forced guidance:
- Precisely fitting collar: The 70 µm filter has an integrated collar that is placed flush over the edge of the Hofeimer.
- Robust drawstring: It is fixed by a reinforced drawstring that presses the filter firmly against the bucket body.
- Full filter performance: Since we deliberately do without a bypass (overflow), all surface water must pass through the high-performance fabric – granulate losses are thus technically excluded.
