We share our secrets

Studies have shown that restaurants are being built like never before and the number has increased by over 25 % in the past few years. There are over 10 million restaurants worldwide and almost all of them are energy hogs. They release hot and poorly purified exhaust air instead of cleaning it and recovering the energy.

Most people are unaware of the fact that every building releases unrecovered energy. By estimate, a restaurant with an exhaust flow of 5000 m3/h is letting out over 15 000 EUR worth of energy – much of which could have been recovered with correct air treatment.

A lot of knowledge and know-how is required in order to succeed in this field. Let us guide you! Read more about air treatment for kitchen exhaust and flue ducts

Examples of loss in Euros
Examples of loss in Euros based on flow and percentage efficiency of purification of the channels, calculated at 40°C exhaust temperature 24h/day, 300 days/year.

We have purified


Exhaust air since 1993

For over 20 years and in more than 50 countries offering Ozone Tech Systems efficient solutions for air treatment. Our ozone generators are developed and manufactured in Sweden, where we make use of ozone-depleting properties, sometimes alone and sometimes in combination with other purification techniques.
