Grenof’s ozone products helping councils and businesses disinfect against COVID-19 Mar 30, 2020


Sunshine Coast based business Grenof has developed a proven technology that can help remove the COVID-19 virus from public and private indoor and outdoor spaces. The Cityscape Ozone Outdoor Disinfection System and Ozone Generator Indoor Gas System are designed to use ozone disinfection to kill the virus.

The COVID-19 virus can live up to three days on surfaces such as plastic and stainless steel including public areas such as bus stops, park benches, hand rails, and internally on door handles, table tops, light switches, floors, ceilings, walls and blinds. The virus can also live in the air for up to 3 hours. 

The Cityscape Ozone Disinfection System works by infusing the ozone in water and using Grenof’s mobile ozone technology to spray outdoor areas on a daily basis, helping to keep outdoor spaces clean, safe and virus free. 

For indoor spaces like office buildings, day care centres, shopping centres, retail outlets and homes, the Indoor Ozone Generator Gas System is a DIY system that businesses and home owners can hire and use to disinfect indoors spaces over a 5 hour period using ozone distributed through the gas system, removing the virus from surfaces. 

Ozone is a safe and environmentally friendly solution that was proven to kill the SARS coronavirus, it is 3000 times more efficient in killing viruses and bacteria than traditional bleaches and chlorine, ensuring a safer environment for people and waterways. 

Managing Director of Grenof Scott Barnes says “ozone is the strongest, fastest, commercially available disinfectant and oxidant in the world, we have been able to use our existing technology to develop an Australian first, possibly world first method in applying it safely. 

“Grenof are experts in ozonation disinfection. We currently use our mobile ozonation technology to disinfect water and sewer pipes daily, throughout Australia. We’ve adapted our pipeline disinfection technology to be distributed airborne for both outdoor and indoor environments to kills viruses in particular the coronavirus. 

“The ozone disinfection systems have huge application benefits for so much of our community. We are working with local councils and outdoor event venues throughout Australia to start implementing the citywide ozone system as quickly as possible so that they can ensure safe and virus free spaces for people to be in whilst outside. 

“Over the coming months government authorities and business owners providing essential services like Centrelink, supermarkets and schools will need to regularly disinfect their premises to ensure a safe environment for everyone. Our indoor ozone generator system will help these businesses deal with this while the virus is at its peak, as well as providing long term disinfectant options as other businesses go back to work.”
