SCIENCE-BASED SOLUTION
Concerns about food-safety, control of decay and ripening, and extending shelf life without depending on harmful chemicals have driven increased demand for safe, proven food storage alternatives such as ozone. The patented, science-based solution from Purfresh generates ozone from oxygen in the air on-site and delivers defined, low-dose, specific concentrations of gaseous ozone into the atmosphere, for use as a powerful but safe disinfectant in controlled atmosphere (CA) and regular atmosphere (RA) storage rooms. Purfresh Cold Storage kills airborne and surface microorganisms, shuts down the sporulation process, and consumes ethylene produced by ripening. After oxidizing microorganisms, ozone immediately reverts to pure oxygen, leaving no residue and maintaining taste, texture and smell characteristics in the product’s natural state. Growers, packers, and processors are able to extend product life and marketability, as well as decrease decay losses of fresh produce naturally. Ozone can be used alone or as a complementary measure with various post-harvest preservation techniques.
Purfresh Cold Storage includes everything you need to have an effective and safe food storage solution without hidden or unexpected costs. Purfresh Cold Storage provides distributed ozone generation and control with a patented ozone generator, ozone monitors, and a local programmable logic controller (PLC). The integrated PLC and ozone monitors provide closed-loop control that ensures optimum safety and efficacy. Centralized monitoring is achieved through an integrated wireless network to a local monitoring station. Purfresh’s Intellipur informatics service provides powerful reporting, alarming, and remote troubleshooting anywhere you are, worldwide, via the Internet.
Installation of the Purfresh Cold Storage solution is simple and will get you up and running quickly. Generators are wall mounted and plug into a standard 120V outlet. Integrated wireless networking eliminates wires between generators and your local monitoring station. Generators are air cooled, eliminating plumbing and maintenance issues that come with water-cooled solutions. An air-preparation subsystem is included in the generator, so no extra plumbing necessary to connect to an external compressor or house air.
