How to succeed?

Our in-house developed RENA-systems are tailored and manufactured in our own facilities in Sweden. Over 25 years of experience has allowed us to map the most common mistakes made during design and installation of ozone systems. Consequently, we have compiled 20 key factors that we believe should be taken into account in order to succeed with your ozone installation. The prerequisite for a successful and efficient air treatment is that the whole “kitchen exhaust air treatment“-chain is properly adapted to the local conditions.
