Ozonetech ozone generators & systems

The very first fully automated disinfection and distribution system perfectly suited for large air volumes in public spaces. The ozone treatment prevent the spread of virus and bacteria, remove mold and unpleasant odor.

This is the ultimate guide to finding out how our turn-key RENA Vivo and RENA Tellus systems are designed. It also introduces the RENA Vitro concept for AOP, Advanced Oxidation Processes for complex wastewater treatment.

RENA Pro is state-of-the-art. For us, this means three things. The treatment capacity is extremely high. The component quality is consistently high in the smallest detail – which ensures long system lifetime with sustained performance. And last but not least, the system is user-friendly.

Read this brochure when you have decided to take a closer look at ozone air treatment in commercial kitchens. It presents the system parts, sizing guidelines and specifications.

The dairy industry is water intense enterprise. With high quality requirements to meet the best possible standards in dairy product quality, ozone can be used to reclaim massive amounts of water which is otherwise discarded. Along with CIP processes, cheese brine is a well-established method to control microbial growth.

A food or hygiene products plant uses ample water that needs to be sanitized or reused. There are also plenty of CIP applications where Ozonetech provides a multitude of solutions for your plant. Why not use the best sanitizing method available?

Mold spores not only cause stale and bad odor, but is also a source of ill health and allergies. In poorly ventilated areas with increased humidity, the mold can easily attach and cause inconvenience a long time before it is visible to the eye. Our ACT 3000 and ACT 5000 ozone generators can handle the problem.

Fat and bacterial formation in the grease trap can cause major odor problems. This brochure tells how the problems can be quickly reduced, and how to install the ozone system.

This is a basic introduction to why the kitchen duct air should be treated: making energy recovery possible, reducing odors, minimizing duct cleaning costs and close to eliminating the risk of fire.

The Part 2 explains differences between high- and low performance air treatment solutions. The guide also illustrates installation principles and lists 20 key factors to consider to ensure a successful installation.

For any size breweries and beverage production, we will help reach a more gentle environmental footprint, reduce chemical costs and handling, ensure best possible process water quality and improve your production uptime. Read more in the brochure what we can offer you.

Garbage rooms, garbage sorting and similar spaces naturally suffer from bad odora. But it doesn't have to be that way. Download the folder, it includes a comparison for the major solutions available on the market. Not surprisingly, ozone takes care of the odors at much lower costs than the alternatives.

The European standard for cleanliness of ventilation systems, EN 15780 has finally been revised after 14 years. The new edition, EN 15780:2025, introduces Annex J, which specifically addresses extract ventilation systems for commercial kitchens.

The EN 16282 standard for commercial kitchen ventilation was released in autumn 2017. This leaflet comments on the new regulations for the major duct air treatment methods. Before choosing treatment method, take a minute to read this.

Bacteria growth in wastewater can lead to unpleasant and malignant gases under acid-free conditions. Two examples are hydrogen sulfide in pump stations and treatment plants. The area surrounding a pump house or water treatment plant is also affected. It is not rare that people living nearby are affected by the odors.

Many shopping centers have chosen to install our systems and one much appreciated benefit is that multiple restaurants can be served by one RENA ozone system.

Do you want to maximize the energy recovery from your commercial kitchen? The trick is to continuously remove the fat from the duct air before it reaches the heat exchanger. This is the how-to-guide.

Then you must follow the new EU regulations, REACH and BPR. We put together some information to help you decide if you need or not need to take action. We also offer services to manage these processes.

Oxygen-fed or air-fed ozone generator? What’s the differences, and do they matter? (The EU thinks it matters and have acted accordingly).

Each process is unique and so are the emissions coming out of the stack. Meticulous in-house pilot tests are needed to find the optimal air treatment solution.

Virtually all industries and businesses release contaminated water. In many cases it consists of a unique composition of hard-to-break-down materials that can’t be broken down by biological processes.

One of the challenges of biogas plants is the strict requirement of H2S removal after the anaerobic digestion stage, before upgrading. Another constant source of concern is the odors emitted from the biogas plant. Today, both can be solved effectively, and green. Let us help you.

Actions are taken all over the world to handle the increasing health issues caused by pharmaceutical residues. Ozone treatment has the capacity to remove the residues emitted from hospitals and the pharma industry.

This six page article is about Ozonetech’s history, the Gilanpour brother’s strong entrepreneurial side, their innovative technique and the prize received for Entrepreneur of the Year from His Majesty King Carl XVI Gustaf at the Royal Castle in Stockholm.

Extensive four-page article by the journalist Dagmar Zitkova complete with photos.

The long-running Swedish campaign “Keep Sweden clean” was an early impression for the Gilanpour brothers when arriving to their new country.

A complete guide to our hoses and parts we use for our ozone systems.

This paper presents different methods using UV light for removing odors and grease emitted from kitchen exhausts and five common myths about UV treatment – still affecting today ‘s market – are presented.

This white paper presents a comparison between two technologies – adsorption and catalytic oxidation – with considerations relevant for choosing the most cost effective method.

Did you know our ozone technology is unique and offers the most compact ozone generators on the market? This white paper highlights the key features of what make our systems and products special.

Ozone water treatment is a growing market. However, many factors need to taken into consideration in order to truly succeed with implementation, reliable results and highest possible efficiency. Ozonetech delivers complete turn-key systems with all aspects of high performance considered. Read about how we do it in this fresh white paper.

The report is produced by Are Oy, a Finnish building and maintenance services company. It provides photos taken at four occasions of kitchen ducts without our ozone treatment, before and after manual cleaning by Are Oy. It also provides photos at the same four occasions of the ducts where our ozone treatment has been installed. The difference is obvious.

This report reviews the hazard posed by NOx air emissions, with particular attention on the potential contribution of air-fed ozone generators.

At the request of Ozonetech, Exponent International Ltd has performed a literature evaluation of the typical by-products produced following the generation of ozone by corona discharge.

Disinfection of drinking water world wide is performed at high stakes. This benchmarking report compares all currently available disinfection technologies today. It can be confirmed by these independent studies that ozone is the most efficient commercially available disinfection method today. The report quantifies the key performance indicators and gives an overview of technical challenges pertaining to all covered technologies.

This WHO report discusses factors for success for most effectively eliminating various pathogens in drinking water, which pose severe problems for populations world wide. Ozone is highlighted as a safe, proven and reliable method for eliminating the complete spectrum of pathogens.
