The majority of interest to date has been for barrel storage rooms. There are AiroCide PPT units operating in both caves and "above-ground" barrel warehouses or rooms. Virtually anywhere in the production process that is an enclosed space is a candidate, like bottling rooms, fermentation rooms and filter rooms. One winemaker has purchased AiroCide to operate in an office environment to protect employees from airborne contaminants that effect productivity and pose health risks.

 

What kind of testing has been done in a winery setting?

 

The AiroCide technology has been tested in a variety of different types of facilities. In a 130,000 cubic foot barrel storage room in Sonoma, CA (which is above ground and has air circulation in the form of a cooling system), the airborne mold/fungi was reduced by 57% in 23 days. The 90,000 cubic foot cave at Hartwell Vineyards in Napa, CA was also tested. Mold/fungi levels there were reduced by 72.3% in 23 days. (See Case Studies)

 

Feedback from wineries using AiroCide PPT is extremely positive. Andy Erickson at Hartwell Vineyards said that their caves "smelled much better" after just 48 hours of the units operating. Schweiger Vineyards winemaker Andrew Schweiger is pleased with the progress in his barrel room. Cameron Perry at Chateau Montelena said they are very happy and their barrel rooms smell a lot better.

Winemakers recognize the problems that airborne pathogen (microbe and gases) can pose to their production process and the overall business of the winery. Currently there are no good, chemical-free solutions to providing clean air in wineries. As more wine producers discontinue using Chlorine based cleaning solutions, mold is becoming more difficult to kill. AiroCide PPT provides winemakers with a way to kill mold and spoilage bacteria while offering added insurance against TCA contamination.

 What is AiroCide PPT?

 

A chemical-free technology that kills airborne molds, bacteria, fungi and viruses - as well as breaks down volatile organic gases (VOC's) like ethylene gas, formaldehyde and TCA in enclosed spaces. AiroCide does not produce ozone or any other by-products.

 

The technology was developed by NASA to enhance plant growth experiments in space. They needed an air purifier that did not emit any byproducts harmful to people or plants, that did not require filters to be changed or any regular maintenance, and would have low energy use.

 

KES was chosen to partner with NASA and the University of Wisconsin to commercialize the technology for the food & beverage industry.

 

How does it work?

 

There is a Photocatalytic Oxidation reactor inside the unit that uses a patented Titanium Dioxide formula for a catalyst. Ultraviolet lamps inside the reactor are what activate the catalyst. The fan draws air in and through the "killing field" and clean air is introduced back into the environment. No chemicals or light can escape from the enclosed unit.
