Project Background
A year-round greenhouse enterprise growing vegetables in controlled environments requested an effective UV disinfection system for its cold storage chamber to preserve product quality.
Cold Room Specifications:
- Volume: 450 m³
- Area: 150 m²
- Ceiling height: 3 m
- Temperature: +13 °C
The goal was to suppress mold growth, eliminate airborne microbes, and prevent bacterial contamination of fresh vegetables, all without using chemical agents. The equipment needed to meet food safety standards since it would be positioned directly above the stored produce.
Proposed Solution
We recommended installing two open-type UVL-Aero 100 UV irradiators with shatterproof protective film. This film retains glass fragments in case of breakage while maintaining ultraviolet transmission for effective disinfection. Internal testing confirmed minimal UV loss through the film, ensuring consistent bactericidal performance.
Technical Specifications
- Type: Open UV irradiator for air and surface disinfection.
- Lamp Type: Ozone-free amalgam UV lamp UVL 19310-144 VOSUV.
- Lamp Power: 320 W.
- UV Output: 105 W.
- Wavelength: 254 nm (germicidal spectrum).
- Housing: Stainless steel AISI 304.
- Lamp Life: Up to 16,000 hours.
- Unit Capacity: Up to 300 m³.
- Safety: Shatterproof film to retain glass in emergencies.
Delivery and Installation
After approval of the technical proposal, a contract and invoice were prepared, covering equipment and delivery. Shipping was completed within 10 business days.
Delivery Package Included:
- Two UVL-Aero 100 units with shatterproof protection.
- UV lamps UVL 19310-144 VOSUV.
- Electronic ballasts (EPRA).
- Certificates, manuals, packaging, and delivery service.
The equipment was installed and is now operational in the cold room. Initial operation confirmed stable performance and high disinfection efficiency. The client is considering adding four more UVL-Aero 100 units for other storage zones.
