What is PCO?

Titanium Dioxide has to be coated on a carrier before it can be used in the ventilation system. Choosing the right carrier for TiO2 is a critical task in developing a world's class Photocatalytic Oxidation (PCO) system. Many PCO systems are still using perforated metal sheet as their carrier but they all have very small contact area. Phototroph uses a three dimensional extruded ceramic filter as the carrier.
We use the progressive thermal dip-coating method to bind our TiO2 sol-gel and the ceramic filter. An anatase Titanium Dioxide layer forms evenly on the ceramic filter surface under a temperature of 500°C. This coated ceramic filter is washable and maintenance friendly that has excellent adsorption, decomposition and sterilization properties.
