DUCT DISINFECTION SYSTEM BASED IN THERMAL FOGGING AND NANOSILVER TECHNOLOGY

Important results from the project

The goal of the project was to develop and comercialize a comprehensive duct disinfection system to control mould and other pathogens in hospitals and other public premises. The system is comprised by a piece of equipment for thermal fogging production and an innovative disinfectant from Prebona AB. The hardware and disinfectant works excellent separately. The disinfectant is very effective according to tests. The created value from the project is extensive! Among other things, Prebona has started using cold fog equipment also for other products such as Prebona OdorControl.

Expected long term effects

The hardware and disinfectant works excellent separately. However, the disinfectant needs to be applied with a fog based on cold fog. A fog with hot fog destabilizes the disinfectant. However, dimmers with cold fog are more efficient and simpler and safer from a user perspective. However, there is a reluctance of the Spanish party to use equipment based on cold fog.

Approach and implementation

The project was performed in two parts. One part intended to develop and optimise suitable equipment for distributing disinfectants in ventilation ducts, carried out by the coordinating partner, Teinova. The other part of the project consists of developing an optimal disinfectant for ventilation ducts and to adapt this to fogging equipment. This part was performed by Prebona. A variety of tests have been performed to optimize the disinfectant. Studies have been conducted with Karolinska Institutet and Uppsala University with very good results on bacteria, fungus and virus.
