A successful prototype can demonstrate that ultraviolet treatment is suitable for a production process. However, converting an experimental device into reliable industrial equipment requires more than copying its external shape.
The manufacturer must verify the treatment-zone geometry, housing dimensions, lamp arrangement, mounting structure, electrical controls, service access, and compatibility with the existing conveyor.
This project involved converting a customer’s working prototype into two custom UVL AERO VOSUV 2-85 conveyor irradiators for a confectionery packaging line in Moscow.
Project Background
A Moscow-based confectionery manufacturer contacted UVL after testing an experimental UV irradiator at its packaging section.
The prototype had produced satisfactory results, so the customer wanted to preserve the original treatment concept. The next step was to reproduce it as complete industrial equipment with properly manufactured housings, standard germicidal lamps, accurately positioned supports, and dedicated control cabinets.
The initial project requirements were:
industry: confectionery production;
application: packaging conveyor;
required quantity: two irradiators;
selected model: UVL AERO VOSUV 2-85;
lamp arrangement: two lamps in each unit;
equipment dimensions: customized for the customer’s conveyor;
electrical configuration: a separate control cabinet for each irradiator;
delivery format: complete production-ready equipment.
The customer required finished systems that could be installed over the existing conveyor—not another prototype or a collection of separate components.
Converting the Prototype into Industrial Equipment
An experimental UV unit is generally built to verify an idea as quickly as possible. It may confirm that the selected treatment position is practical, but it does not necessarily account for continuous operation, service access, electrical safety, or repeatable manufacturing.
UVL therefore used the customer’s prototype as a functional reference rather than as a finished design.
The production version had to account for:
the width of the conveyor;
the height of the treatment zone;
the dimensions of the stainless-steel housing;
the distance between the supports;
clearance for packaged products;
the position of both lamps;
access for lamp replacement and cleaning;
safe cable routing;
placement of the control cabinet;
integration without obstructing product movement.
These dimensions were coordinated with the customer before manufacturing began.
Why Custom Geometry Was Necessary
A standard conveyor UV irradiator would not necessarily fit the available section of the packaging line.
The housing width, support spacing, and installation height had to correspond to the actual conveyor. Even a small mismatch could obstruct the packaged products, interfere with adjacent equipment, or make lamp servicing unnecessarily difficult.
For this reason, the UVL AERO VOSUV 2-85 units were manufactured according to the agreed dimensions of the customer’s line.
The objective was to preserve the operating concept already tested by the confectionery manufacturer while converting it into a mechanically accurate and maintainable industrial design.
Selected Equipment
UVL manufactured two UVL AERO VOSUV 2-85 conveyor irradiators.
Each unit included:
a stainless-steel industrial housing;
two germicidal UV lamps;
a support structure adapted to the conveyor;
electrical connection components;
a separate control cabinet;
service access for scheduled lamp replacement and maintenance.
The two-lamp configuration created a defined UV treatment zone above the packaging conveyor. The housings and supports were manufactured to fit the available installation area without changing the operating principle of the line.
Each irradiator received its own control cabinet, making the units electrically independent and simplifying their operation and maintenance.
Preserving the Proven Treatment Concept
The customer’s prototype had already confirmed that the proposed installation point and general irradiation arrangement were suitable for further development.
This allowed the engineering team to focus on industrializing the design rather than changing its underlying concept.
Compared with the experimental unit, the finished equipment provided:
accurately manufactured and repeatable dimensions;
stainless-steel protective housings;
standard two-lamp assemblies;
stable supports designed for the conveyor;
organized electrical connections;
separate control cabinets;
practical access for servicing;
a cleaner and more professional installation.
The project retained the successful idea while eliminating the limitations of an improvised prototype.
Commercial Requirements
The project also had to pass the customer’s internal budget approval.
UVL reviewed the configuration to preserve the required custom geometry, two-lamp design, and separate control cabinets without adding unnecessary components. An additional discount was approved for the order, allowing the customer to retain the required industrial configuration within the available budget.
The resulting solution remained a complete system rather than being reduced to loose lamps, power supplies, and unfinished housings.
Manufacturing and Delivery
After the dimensions, configuration, and commercial terms had been approved, both UVL AERO VOSUV 2-85 units entered production.
The manufacturing process included:
fabrication of two custom stainless-steel housings;
production of supports according to the conveyor dimensions;
installation of two germicidal lamps in each unit;
assembly of two separate control cabinets;
preparation of electrical connections;
final assembly and inspection.
The customer received two complete conveyor irradiators ready for installation at the Moscow production site.
No additional housing development or assembly of separate UV components was required at the facility.
Benefits for the Customer
The project provided the confectionery manufacturer with several practical advantages:
equipment manufactured for the actual conveyor dimensions;
preservation of a UV treatment concept already tested by the customer;
two complete industrial UVL AERO VOSUV 2-85 irradiators;
two-lamp configuration in each treatment zone;
a separate control cabinet for every unit;
integration without rebuilding the complete packaging line;
predictable access for cleaning and maintenance;
a configuration adjusted to the approved project budget.
Process Validation
Positive results from a prototype provide a useful starting point, but the final industrial installation should still be validated under normal production conditions.
The effectiveness of UV treatment on a packaging conveyor depends on:
conveyor speed;
treatment-zone length;
exposure time;
lamp output;
distance between the lamps and packaging;
product orientation;
shadows created by the packaging geometry;
cleanliness of the lamps and internal surfaces;
target microorganisms;
required microbial reduction.
If parts of the packaging remain shaded, they may receive a lower UV dose. Microbiological testing should therefore be performed using the actual products, conveyor speed, and operating conditions.
The fact that the lamps are operating does not by itself confirm the required disinfection result.
UVC Safety
Direct germicidal UVC radiation is hazardous to the eyes and skin. Industrial conveyor irradiators must be installed so that direct and reflected radiation cannot reach personnel working near the line.
Depending on the final installation, appropriate protective measures may include:
shielding around the treatment openings;
protective curtains or light barriers;
access interlocks;
emergency stopping devices;
warning labels;
controlled maintenance procedures;
verification of UVC leakage after installation.
The irradiators should be de-energized before the housings are opened for cleaning or servicing.
Conclusion
This project transformed a successful experimental device into two production-ready UVL AERO VOSUV 2-85 conveyor irradiators.
The original treatment concept was preserved, while the mechanical structure, lamp arrangement, supports, electrical connections, and control system were redesigned for industrial operation.
The confectionery manufacturer received two complete units manufactured to the real dimensions of its packaging line. This allowed UV treatment to be introduced without reconstructing the complete conveyor and demonstrated how a tested prototype can be developed into reliable production equipment.
