Product Spotlight: Purfresh Extends Cold Storage Solution With New Multi-Room Control Box

Purfresh, a provider of clean technologies that purify, protect, and preserve food and water, has announced the release of its Purfresh Multi-Room Control Box (MRCB) technology. Integrated with Purfresh Cold Storage and Purfresh’s Intellipur software analytics, this innovation enables a single ozone generator to precisely distribute and control ozone in up to 16 cold storage rooms. Distributing the power and intelligence of Purfresh ozone generators across multiple locations ensures retailers, distributors, and international cold storage operators can cost effectively take advantage of ozone to enhance food safety, reduce decay, and control ripening throughout their facilities.


“Industrial-strength ozone solutions have traditionally been designed for facilities with rooms that are a few hundred thousand cubic feet in size, which makes those solutions impractical for facilities with banks of smaller rooms,” says Andy Smith, vice president of products for Purfresh. “This reality limited the ability for countless produce storage facilities around the world to leverage the natural purification powers of ozone. In response to increased demand from this industry segment, we developed the MRCB, a cost effective solution optimized for the unique needs of agricultural environments that monitors and delivers ozone to many rooms without compromising worker safety or reliability.”

Each MRCB is capable of monitoring and delivering ozone to four or eight rooms, and two MRCBs can be configured with a single Purfresh generator to deliver ozone to a total of 16 rooms. Each MRCB is equipped with a Programmable Logic Controller (PLC) that accurately controls and distributes low doses of ozone through specifically designed ozone resistant valves. The PLC also communicates directly with the main generator to execute 15 unique safety alarms to keep both workers and produce safe.

Specifically engineered for refrigerated storage environments, the Purfresh Cold Storage technology ensures food safety and quality by combining a scalable, plug-and-play ozone-based solution with Purfresh Intellipur online analytics, an information service that includes environmental sensing, Web-based monitoring, alerting, data reporting, and analysis along with remote control and diagnostics. These state-of-the-art technologies allow growers, produce distributors, and retailers to enhance their food safety measures and effectively maintain postharvest quality by regulating the ripening process and reducing decay all without the use of chemicals.
