Citrus Warehouse PCO Study Results

Not only is Airocide in operation for thousands of customers in North America, our technology can be found all over the globe. For example, a study conducted in the refrigerated citrus warehouse of a produce wholesaler in Valencia, Spain revealed the effectiveness of the Airocide system in reducing mold spores. Two Airocide ACS-100 units were used to purify the air in a 43,400 ft3 warehouse containing oranges. Air samples were taken twice over a seven day period, once at the beginning to establish a baseline for the airborne mold in the facility without Airocide, and once after 7 days with the two units active and on.

After 7 days at a temperature of 54°F, the Airocide PCO air purification system had eliminated 79% of the airborne mold in the refrigerated warehouse. More details on this study are available here on our website, and along with a variety of other studies on our PCO technology, it shows that Airocide effectively reduces those pathogenic threats that contribute to premature spoilage and mold in food storage.

Design of Cold Storage for Perishables: Protect the Air with PCO!When designing a cold storage facility, whether for fruits and vegetables, flowers, meat, dairy, or any other perishable product, there’s one key element that can set your facility apart from the rest. The quality of the air, and the effectiveness of your air purification system could mean the difference between storage and spoilage.

Food safety, facility sanitation, and operating costs depend on a system that efficiently and effectively scrubs the air of mold, bacteria, and ethylene gas and other gaseous organic compounds. Airocide is the solution that will let you perfect the design of your cold storage facility, with all the effectiveness of Developed for Nasa photocatalytic oxidation (or PCO).

More Effective Air Purification with PCO Technology

Because of airborne threats like ethylene gas, mold spores, and bacteria, air purification is paramount in cold storage. But, when it comes to items like fruits and vegetables, products can bring in their own contaminants: ethylene gas, mold, and bacteria spores. Even if they’re thoroughly sterilized, ripe fruits and vegetables put off a gas called ethylene, which speeds ripening and can cause certain plants to overripen or spoil. This  volatile organic compound, or VOC, collects in enclosed spaces, affecting other produce items prematurely as more collects.

But there’s a solution, developed for NASA for the space station and perfected for use on earth by the scientists and engineers at KesAir.

Photocatalytic oxidation, otherwise known as PCO, was developed to help astronauts eliminate ethylene from the space station. The VOC was being produced by an experiment on growing food plants in space. Ethylene was ripening the plants too quickly – but after install, the PCO technology eliminated it, and it was found to destroy bacteria and viruses in the air as well.

Designing Cold Storage With Photocatalytic Oxidation

Today, that same PCO air purification technology is available, and it’s the ideal air purification system for the design of your cold storage facility. That’s because, from the very beginning, we’ve been developing PCO air purifiers to fit a wide variety of spaces – developing systems that can effectively and efficiently scrub the air no matter how large or small the space.

With a PCO air purifier installed, you’re killing airborne threats in your refrigerators or coolers. That means bacteria and mold has less of a chance of landing and spoiling delicate produce, and VOCs that would normally circulate in the air are removed completely – converted to harmless trace elements of carbon dioxide and water vapor. With Airocide air purifiers, you can also be sure your entire space is protected – we can use the measurements of your facility to create a custom Airocide system.

It’s easy to use and operate, and low-maintenance as well – and you can even protect your back offices and common areas with the same proven technology, thanks to our AiroPro line of purifiers.
