Ozone Active Atmosphere Protection for Higher Quality Arrivals

For years, growers and shippers tried to protect their cargo with traditional controlled or modified atmosphere systems, fungicides, and temperature recorders. But these systems lacked vital capabilities. They couldn't reduce decay, reduce pathogens, control ripening, and enhance food safety simultaneously. They couldn't be monitored in real time. And the reefer conditions couldn't be adjusted en route.

Purfresh solves these deficiencies with full transparency real-time monitoring and ozone response. Proven, cost effective, and chemical free, Purfresh is the ideal solution for cargo requiring strict ethylene, humidity, oxygen, and carbon dioxide adherence, and comprehensive post-voyage data. With Purfresh, everyone—from the exporter to the consumer—benefits from higher-quality products, reduced losses, and a more sustainable global supply chain.

Purfresh Works the Way Shipping Works

Purfresh active atmosphere technology is not only highly effective, it’s also easy to use. Designed to align with existing logistics processes, the Purfresh system offers shippers and carriers alike a number of benefits, including:

  • Global availability—Purfresh is broadly available from ocean carriers all over the world.
  • “Per-Trip Service” flexibility—Just ask for Purfresh when the cargo needs extra protection.
  • Compatibility—Purfresh works with entire fleet; it’s not limited to new or leak-proof containers.
  • Pre-trip simplicity—The portable unit simply mounts into the existing evaporator fan access panel and can be operational in as little as 15 minutes. No special pre-trip preparation is required (e.g., leak tests, curtains, etc.).
  • Non-intrusiveness—Purfresh does not take up valuable cargo space inside the container.
The Power of Ozone

Purfresh is the only solution proven effective to minimize decay, control ripening, and enhance food safety without the use of chemicals, making it an ideal solution to protect decay-prone or ethylene-sensitive cargo. Scientifically engineered, the system enhances the atmosphere inside the container with an active form of oxygen—commonly referred to as ozone—to control molds, yeasts, ethylene, Salmonella, E. coli, Listeria and other contaminants in the air and on surfaces. Because it uses oxygen from the air, Purfresh is able to continuously generate ozone throughout the voyage.

Certified for use with organic produce and approved by the USDA and the FDA, ozone acts as a powerful, residue-free disinfectant that immediately reverts to oxygen, leaving the product’s natural taste, texture, and smell intact.

Purfresh ozone active atmosphere panels are easy to install, operate, and maintain. The panel simply mounts into the existing evaporator fan access panel and can be operational in as little as 15 minutes.

Much simpler than traditional CA/MA shipments, Purfresh does not require airtight environments or curtains, nor does it take up cargo space inside the container.

Equipped with the Intellipur monitoring and tracking software, the Purfresh system provides an unparalleled level of transparency by monitoring the temperature, relative humidity, carbon dioxide, oxygen, and ozone, as well as the location of the container via GPS tracking. This level of en route visibility can help shippers avoid catastrophic loss by being able to quickly identify problems (such as closed vents) and take the appropriate action before it’s too late to save the load.
