Ozone Sterilization Oven

The Ozone Sterilization Oven (LEGOS series) disinfects tools, packaging, garments, containers and other heat-sensitive items with ozone at low temperature, in place of UV, steam or dry-heat cycles. Five cabinet volumes are listed, from 300 L (LEGOS-300) to 6500 L (LEGOS-6500). Listed users span pharmaceutical, hospital, chemical, food and archive work.

How it works

An ozone generator inside the cabinet raises the ozone concentration in the chamber air to 50 ppm or more. Ozone is a strong oxidant; at sufficient humidity it reacts with microorganisms in the air and on exposed surfaces, breaking down enzymes, cell membranes and genetic material. Sterilization takes 35 to 60 min at a chamber temperature of 10 to 40 °C, so items that would be damaged by heat can be treated. Ozone leaves no residue.

The cabinet is built entirely from stainless steel. Single-door and double-door models are offered. A front and rear door interlock can be fitted, and the cabinet can be built into a wall so that loading and unloading take place on opposite sides of a partition, or a delivery window can be substituted. Table values are given for type selection only.

What is included

• Stainless steel cabinet, single or double door
• Ozone generator
• Optional: front and rear door interlock; wall-mounted pass-through arrangement or delivery window

Specify for your project

• Chamber volume, 300 to 6500 L, or a custom inner size
• Single-door or double-door, and whether a pass-through installation is required
• Items to be treated and the required ozone concentration and exposure time
• Ambient temperature and humidity at the installation site
• Power supply: stated in the project datasheet

This description defines the product family. Guaranteed performance, included hardware, exclusions, interfaces and acceptance criteria are stated only in the project-specific technical proposal and approved datasheet.

Generally, the sterilization principles are as follows:

1. The ozone inactivates and kills the bacteria through oxygenolysis of enzyme required by the glucose of the bacteria.
2. The ozone has direct reaction with bacteria and virus to damage their organelle, DNA and RNA, as well as metabolism of bacteria, thus to kill the bacteria.
3. The ozone invades in the cell through membrane organization and acts on the lipoprotein of outer membrane and inside lipopolysaccharide to cause permeabilitydistortion of bacteria, thus to dissolve and kill the bacteria.

The ozone is featured by strong sterilization without residue, and is applicable to sterilization of mold, raw and auxiliary materials, packing materials, work clothes, containers and appliances of pharmacy, biological product, hospital, and chemicalindustry; it can be used to replace the UV radiator and high temperature & pressure sterilization.What’s more, it is free of secondary pollution. The ozone is widely applied in.

Sterilization of medical treatment and public health industry, food and drinks industry, preschool education system, financial system, and system of library books and archives, such as disinfection and storage of drug ware, surgical instruments and clothes; disinfection and mold control of books, archives and paper moneys; refreshment of fruits, vegetables and other items to be disinfected and stored at normal temperature.

Features

1. It is manufactured with stainless steel in whole and designed with mechatronics.
2. The ozone sterilization is adopted to produce rapid and thorough sterilization without secondary pollution.
3. The high-quality device with reasonable structure is used as ozone generator to produce long service life and stable ozone output.
4. There are several options for customers, including single-door and double-door models.
5. The front/rear door interlocking mechanism may be adopted. The whole cabinet may be inserted in the wall, and the both sides of partition may be used for placing or picking materials or replacing the delivery window, so as to meet special requirement of the customers.
