GermAwayUV Horticulture Disinfection Chamber

Select the Ultraviolet Wavelength for Your Application

Each chamber is supplied with one complete lamp configuration selected at the time of purchase. The chamber design, quartz shelf, double-sided exposure, controls, coverage area, and safety features remain the same; the installed lamp type determines the ultraviolet wavelength range produced by the system.

Designed for Horticultural Treatment and Disinfection

Fungal contamination, including Botrytis cinerea, gray mold, storage rot, and powdery mildew, can damage flowers, plant material, fruits, herbs, vegetables, and finished horticultural products if it is not properly controlled. Many conventional treatment methods rely on fungicides or other chemical agents that may be unsuitable for sensitive products or certain production processes.

The UV-C configuration provides a nonchemical method of exposing specimens to germicidal ultraviolet energy. UV-A and UV-B configurations are available for applications requiring their respective wavelength ranges while preserving the chamber’s controlled enclosure, programmable operation, and double-sided exposure design.

Double-Sided Exposure Through a Quartz Shelf

Standard glass, plastic, fabric, and many other common materials block or substantially reduce ultraviolet transmission. The chamber therefore uses a quartz plate shelf designed to allow ultraviolet energy from the lower lamp bank to reach the underside of the specimen while the upper lamp bank exposes the top surface. This double-sided design helps deliver more thorough and repeatable coverage than a single-direction light source.

Built for Production Environments

In addition to its horticultural treatment capabilities, the chamber is designed for repeated use in production, laboratory, greenhouse, and processing environments. Its core construction is based on GermAwayUV ultraviolet laboratory chambers used by universities and research facilities throughout the world.

Designed, engineered, and manufactured in the United States, the chamber provides a controlled and repeatable ultraviolet process without requiring operators to manually hold or reposition a UV source during treatment.

Features

• Choice of UV-A, UV-B, or UV-C Lamps: Select the wavelength range appropriate for your application when ordering the chamber.
• Double-Sided UV Exposure: Upper and lower lamp banks expose specimens from both directions to reduce shadows and untreated areas.
• Sixteen High-Intensity Lamps: The chamber surrounds the treatment area with high-output ultraviolet energy. The exact wavelength depends on the selected UV-A, UV-B, or UV-C lamp configuration.
• Programmable Timer: Treatment cycles can be programmed from 1 second to more than 2 hours in one-second increments. The chamber automatically stops when the programmed cycle is complete, improving repeatability and reducing the risk of overexposure or underexposure.
• Removable Shelf: The shelf can be removed to simplify loading and unloading. Additional shelves may be ordered so that one batch can be prepared while another batch is being treated.
• Quartz Glass Shelf Insert: The quartz plate permits ultraviolet energy from the lower lamp bank to pass through the shelf and reach the underside of the specimen.
• UV-Filtered Safety Glass: The viewing window allows operators to observe the specimen and treatment cycle while helping block hazardous ultraviolet radiation.
• Automatic Door Interlock: Opening the chamber during a treatment cycle automatically turns off the ultraviolet lamps to help prevent accidental exposure.
• Production-Grade Construction: Designed for frequent operation in horticultural, processing, research, and laboratory environments.

Determining the Appropriate Treatment Time

Required treatment time varies according to the selected wavelength, lamp intensity, organism, specimen type, product density, distance from the lamps, surface orientation, contamination level, and shadowing. Because real-world conditions vary, a single treatment time cannot be guaranteed for every application.

The dosage calculator below may be used as a starting point when developing and validating a repeatable process. For example, the previous UV-C dosage calculation for Botrytis cinerea indicated a minimum exposure time of approximately 36 seconds under the specified test conditions. Actual production processes should be tested and validated for the material and conditions being treated.
