Problem
In both centers, the food courts host several types of cuisines that release high concentrations of grease in their exhaust air, such as hamburger and Asian restaurants. The grease causes serious risk of fire in the duct system and emissions disturbing odors in the surrounding neighborhood since it tends to stick to the duct walls in the ventilation system if not treated continuously.
Besides a sustainable solution for treating fatty compounds, aligned with the company’s environmental goals, Ingka Centres also required a single air treatment unit to manage exhaust air from several restaurants.

Solution
In order to treat the high grease loads from the food courts, we delivered an Ozonetech RENA 80 ozone system to each shopping center. Safety was also important for Ingka Centers, so they ordered solutions equipped with our online monitoring and control system, O3Eye™, which was also integrated to their internal property management systems.
Evaluation
The Ozonetech RENA 80 ozone systems, with a capacity of 7,000 l/s, are currently treating exhaust air from multiple restaurants at the same time, preventing fat from depositing on the duct walls. What has previously been a serious challenge for the property owner is now handled efficiently, sustainably and safely. Our O3Eye™ control system is continuously online and monitored by our technicians to prevent malfunctioning.
