Guardian Ozone Generators


Ozone is highly effective at destroying harmful pathogens as well as reducing ethylene build up in the cold storage environment. An ever increasing number of tree-fruit cold stores are incorporating ozone into their storage and washing operations to improve the storage-life, pack-out, product safety and quality.


Guardian Ozone has 20 years’ experience in manufacturing ozone generation equipment and have established themselves as technology leaders for CA storage Ozone.




Cold Storage:

Fruit cold store operations have found that storing fruit in atmospheres with a low concentration of gaseous ozone can significantly improve fruit quality and sanitation. Gaseous ozone controls pests, supresses ethylene production, controls bacteria and prevents mould sporulation and nesting – all leading to higher fruit pressure and increased packout.

Direct Product Sanitation:

Ozone sanitation is USDA, FDA and Organic Program certified to reduce and control listeria, salmonella, e.coli, and other pathogens.

Environmental Sanitation:

Aqueus ozone wash-down of equipment, belts and floors provides effective sanitation at your facility, improving product quality and safety.
