Product Description

The Modular Conveyor-Mounted UV-C Sterilization Module is an easy-to-install, space-saving UV disinfection solution specifically developed for packaging lines where physical space is constrained but microbial control on transparent packaging surfaces is required. Unlike bulky, full-tunnel systems requiring dedicated floor space, this modular design mounts directly onto existing conveyor side rails using adjustable brackets, requiring zero modification to the original conveyor frame.

The system delivers high-intensity UV-C light at 253.7nm to sterilize packaging surfaces passing beneath (or between) the lamp heads. UV-C photons destroy the DNA of surface microorganisms including bacteria, viruses, and molds, achieving a 3–5 log reduction (99.9%–99.999% kill rate) for common food pathogens in seconds.

Specifically engineered for transparent packaging applications such as pre-formed trays, cups, bottles, jars, closures, flow packs, pouches, and thermoformed containers, this modular approach allows food processors to rapidly deploy UV disinfection to individual packaging lines without major capital investment. The system is available in single-bank, dual-bank, or multi-bank configurations (top-only, bottom-only, double-sided top+bottom, or top+bottom+side). The modular lamp cartridge design allows tool-free lamp replacement, keeping maintenance downtime to under 5 minutes per lamp.

With its compact footprint, bolt-on mounting system, and external control box that can be wall-mounted or floor-stand positioned nearby, this module occupies zero additional production floor space beyond the existing conveyor. It is ideal for automated filling lines for dairy, ready meals, sauces, produce, beverages, and pharmaceutical packaging requiring high hygiene standards with minimal line disruption. The system can be installed during a weekend shutdown and returned to full production by Monday morning.

FAQ

Q: How do I know if this module can fit on my existing conveyor?
A: Our application engineering team provides free assessment. We require only three measurements: conveyor belt/frame width, height clearance above conveyor, and distance from side rail to nearest obstruction. For complex installations, we offer site visits or video-call assisted measurements.

Q: Can I install the module myself, or is professional installation required?
A: The module is designed for straightforward DIY installation for qualified electrical and maintenance staff. We provide a step-by-step installation guide. However, our paid installation service ensures full safety verification, UV intensity mapping, and control system integration.

Q: How many lamp modules do I need for my conveyor width?
A: Each module covers 200–800mm of effective width. For a 600mm‑wide conveyor, one module typically suffices. For wider conveyors, multiple modules can be mounted side-by-side. Our free feasibility assessment will specify exact module count.

Q: Will the UV light damage my conveyor belt?
A: Most standard conveyor belts (PVC, PU, stainless steel mesh, modular plastic) have very high UV-C resistance. However, rubber belts and some specialized belts may experience surface degradation. We include belt material compatibility as part of our pre-installation assessment and provide shield plates for sensitive belts.

Q: What is the payback period for a modular UV system compared to chemical sanitizers?
A: ROI is typically achieved in 6–12 months due to immediate elimination of chemical purchase costs, elimination of chemical storage and handling requirements, elimination of rinse water and wastewater treatment costs, and reduction in spoilage-related product returns. The low capital cost of the modular system and minimal installation expense further shorten payback periods.

Q: How often do lamps need to be replaced?
A: High‑output amalgam lamps reach 12,000–16,000 hours (3–4 years of continuous operation on 12-hour daily shifts). The HMI displays remaining lamp life hours and triggers a replacement reminder. We recommend stocking a full set of replacement lamps to minimize downtime for lamp change.
