Elevate Indoor Air Quality with Photocatalytic Oxidation (PCO) Technology

Neutralize contaminants for a healthier indoor environment

Unleash the Power of PCO Technology for Superior Air Purification

Field Controls is Leading the Way with Advanced Air Cleaning Technology

Field Controls, founded in 1927, has been a pioneer in developing air purification technology utilizing innovative ultraviolet technology. We build products that that clean the air in both businesses and homes throughout North America and abroad. In conjunction with ultraviolet (UV) light, we also build products that harness the power of Photocatalytic Oxidation (PCO) technology to remove volatile organic compounds (VOCs), odors and microorganisms from the air. Our staff of engineers has been hard at work developing cutting-edge PCO products to serve the needs of both homeowners and businesses. We believe all businesses and homes should be free from harmful air, so we are dedicated to delivering best and most reliable PCO solutions available.

Understanding Volatile Organic Compounds (VOCs) and the Power of PCO Technology in Eliminating Them

Field Controls photocatalytic oxidation (PCO) technology offers a range of important benefits for air purification including neutralizing volatile organic compounds (VOCs) odors and even certain pathogens. We experience VOCs through our homes and businesses. VOCs may include:

  1. Formaldehyde: Found in building materials, furniture, and household products.
  2. Benzene: Present in tobacco smoke, gasoline, and industrial emissions.
  3. Toluene: Found in paints, solvents, and adhesives.
  4. Xylene: Present in paints, varnishes, and cleaning agents.
  5. Acetone: Found in nail polish remover, paint thinner, and adhesives.
  6. Ethanol: Present in alcoholic beverages, fuels, and personal care products.
  7. Methanol: Found in cleaning products, paints, and antifreeze.
  8. Trichloroethylene: Present in some cleaning agents and industrial solvents.
  9. Perchloroethylene: Found in dry cleaning solutions and spot removers.
  10. Formaldehyde: Present in some cosmetics, disinfectants, and pressed wood products.

Some homes and businesses experience lingering odors. PCO technology proves especially efficient in reducing stubborn and lingering odors, like those stemming from cooking, pets, or chemicals. Furthermore, PCO technology contributes to enhancing indoor air quality by reducing allergens, mold spores, and other airborne irritants. Our PCO technology is designed with energy efficiency in mind and requires minimal maintenance, offering a convenient and cost-effective solution to create cleaner and healthier indoor environments.

How does Photocatalytic oxidation (PCO) work?

Photocatalytic Oxidation Chart

Photocatalytic Oxidation (PCO) technology utilizes a combination of UV-C light and a specific catalyst. In Field Controls PRO-Cell (PCO) products we utilize titanium dioxide as the catalyst. When the titanium dioxide is exposed to our powerful ultraviolet light (UV-C) lamps, it creates a reaction which converts the odors, VOCs and more to odorless and harmless water vapor and carbon dioxide.

During the chemical reaction, the titanium dioxide absorbs the UVC light and becomes energized. This energy enables the titanium dioxide to interact with both oxygen and moisture in the air. As a result of this interaction, highly reactive oxygen compounds, hydroxyl radicals and superoxide ions, are created. These compounds are oxidizers which attack and break down the VOCs and pollutants in the air.
