How It Works

Inside our Photocatalytic Air Purifier

What is a Photocatalytic Air Purifier and what can it do for me?

A photocatalytic air purifier is a device that uses photocatalytic oxidation (PCO) to convert fine particles and toxic gases into safer compounds. PCO is an approved method for reducing bacteria and removing pesticides from fruit and veg stores. High-intensity ultraviolet light of the germicidal (254 nm) wavelength is the first part of the process that acts on the air coming into the machine and starts to degrade toxic organic compounds. The filters arranged inside the machine are at right angles to the air flow and are positioned between pairs of UV light tubes along the body of the machine. The filters are coated with a Photocatalyst which reacts to the UV light and produces Hydroxyl radicals which breakdown organic compounds thus reducing fungal, bacterial and viral microorganisms.

Technology of our Machines

What makes White Air Solutions PCO`s the choice for your application over other PCO`s on the market. The configuration of our machine with the UV tube and filter arrangement is enhanced more than other machines. The type of Photocatalsyt and its dopant partner make an enhanced catalyst which increases the rate of attack on organic compounds. The light chamber where the PCO process occurs is superior as we have increased the reflective value in the chamber increasing the reaction with the Photocatalyst and the light from the UV tubes is more effectively used to react with the passing air.

Stage One

Ultra-violet Light

High-intensity ultraviolet light of the germicidal  (254nm) wavelength is the first part of the process that acts on the air coming into the machine this starts to degrade toxic organic compounds.

Stage Two

Filters

The filters arranged inside the machine at right angles to the air flow, are positioned between pairs of UV light tubes along the body of the machine.

Stage Three

Photocatalyst

The filters are coated with a Photocatalyst which reacts to the UV light and produces Hydroxyl radicals which breakdown organic compounds thus reducing fungal, bacterial and viral microorganisms.

Testimonials

By our valued clients

  • I most certainly would recommend the White air system in the retention of quality and of market management of the product.

    Neil Chambers Technical Manager, Commercial Flower Company
  • After a very short while we observed better air quality and the pigs were most certainly performing better.

    N Smith Pig Farmer
  • We have now been using the PCO technology for 3 years to remove ethylene gas and other fungal and bacterial pathogens from brassica crops in our cold storage rooms with positive results in terms of improved storage life and quality.
