How trioxygen is cleaning up on campus

A new generation of powerful deodorisers and sanitisers is helping clean up on campuses across the UK

The Gteck range from Oxford-based Greenteck Global is harnessing the power of trioxygen – an elemental force as old as the planet itself – to provide high-tech cleaning solutions for the 21st century.

Trioxygen, or ozone (O3), occurs naturally in our atmosphere, most noticeably in the ozone layer, and is produced by lightning over the oceans. People visiting the coast often say they can ‘smell the ozone’.

The Gteck units use UV light to produce trioxygen in carefully controlled amounts and rates. The extra electron in the oxygen ‘attacks’ odours, grease, mould spores and even smoke damage.

But at the end of the process the O3 simply decays back to normal oxygen (O2). So as well as providing significant cost-saving benefits compared with using traditional, aggressive, chemical cleaning methods, the Gteck system is safe, easy-to-use and environmentally friendly.

Greenteck Global produces a range of units from one small standard electrical socket to provide constant background deodorising to the powerful generator that can be used for ‘shock-treatment’ in a particularly badly affected location.

There is also a Gteck Destruct unit: fully compatible with the generators, it operates automatically at the end of a cleaning cycle to neutralise any unused trioxygen. In addition to the standard deodorising and sanitising, the units can be installed with – or retro-fitted to – extraction systems in commercial kitchens to degrease and remove cooking odours.

For universities and colleges one of the main uses for trioxygen is in student accommodation. This is especially true at this time of year when cold, wet weather means the heating is turned up, windows are kept closed, and dirty, wet clothing is often left piled in corners and so mould and odour are almost perennial problems.

Over the past year, Greenteck Global has installed units to universities up and down the country including Cardiff, Leeds, Manchester, Oxford Brookes, Royal Holloway University of London, Falmouth and Optivo Welkin Halls of Residence Eastbourne.

Cardiff uses the plug-in units to control malodour in student rooms. Leeds has now purchased wall-mounted Aura units for a number of stairwells where there were issues with malodour migrating between floors. It also bought the Airteck 1000pd for quick turnaround rooms where malodour is caused by students eating or smoking in rooms.

In Manchester, the Aura unit and an Airteck 5000p were installed in a corridor, directly opposite toilets, which led to management offices. Oxford Brookes purchased the AirTeck 10000pd for the main gymnasium, which houses around 30 rowing machines; the university now ozonates the gym overnight to remove malodour and freshen the air space for the following day.

Royal Holloway had a major mould issue in a five-bedroom student house. GTG deployed the AirTeck 1664 ozone shock system to remove the problem. Falmouth used a number of plug-in units used for odour control in specific student rooms. Optivo Welkin has a 5000p unit currently on trial for use in old accommodation with mould issues.

David Thurston, founder and head of Greenteck Global, said: “Following on from participating at the CUBO summer conference last July, we have had a fantastic response from a number of universities. Initial site trials have now concluded with our ozone units being deployed permanently.

“Ozone now plays a major part in day-to-day housekeeping regimes and we have proved that ozone is far more effective on all malodour issues from student lifestyle to mould and washroom-related odours.

“We are extremely pleased with the response so far and continue to get fresh enquiries from universities battling with the exact same issues. We continue to support the university sector with our products and services and welcome fresh enquiries to trial our systems.”
