RENA Pro

The RENA Pro is Ozonetech’s premium ozone treatment solution for air treatment. The applications range is very broad, spacing from highly efficient removal of H2S in industrial plants to odor removal in commercial ventilation. The system includes high-performance ozone generation, together with optional features such as specialized oxygen concentrator for maximum efficiency, safety systems and high quality material tubing & piping; all packed and mounted on a compact skid.

The RENA Pro is a platform with exceptional modularity, adapting the ozone capacity to meet the customer's needs and requirements. Therefore, we offer five series of the RENA Pro solution, categorized depending on ozone capacity, from A to E. 

Overall benefits of the RENA Pro solution:

  • Highly efficient ozone generation reduces energy consumption and footprint
  • Stable and reliable ozone production over time:
  • High quality fed-gas used (concentrated, dried oxygen from oxygen generator)
  • Pure ozone output. No by-products such as NOx, no nitric acid (HNO3) nor salt formation; extending longevity of system
  • Efficient heat management (liquid cooling) for stable and reliable operation, also extending longevity of system
  • Minimized maintenance due to clever design; pure, dry oxygen fed-gas and liquid cooling
  • Teflon-hose ozone distribution
  • Rugged design for harsh environments
  • Option: remote control and monitoring with O3Eye™

In addition to the benefits above, the RENA Pro-solution offers specific advantages for H2S applications:

  • Great H2S reduction
  • Odor control
  • Lower risk of corrosion problems
Air Treatment Ozone System RENA Pro A-series

RENA Pro A-series

The A-series are the smallest capacity ozone systems, with capacities up to either 5 or 10 g O3/h. These systems are perfect to deliver high-quality ozone to applications such as microbial disinfection (e.g. salmonella) or high-intensity odor removal in venting applications.

RENA Pro B-series

The RENA Pro B-series is the most common package as it can reach ozone capacities up to 120 g/h, which is perfect for applications such as odor removal in venting applications (lower capacity B-series) and H2S removal in wastewater treatment plants (higher capacity B-series). The solution has a compact design, requiring only 80 x 60 x 180 cm. Cooling water varies between 1-6 l/min depending on model, which can be supplied on-site or with a custom-made closed cooling system. The power requirement varies as well, starting from 0.25 kW.

RENA Pro C-series

The C-series is used for applications where large air flows or pollutant concentrations are reached, such as industrial H2S removal e.g. methane upgrading.  Alternatively it can be used for when ozone is required in many different areas in lower concentrations. The unit can act as an “ozone central” where the ozone capacity is split depending on the customer’s needs. The capacity can reach up to 240 g O3/h, cooling water requirement of 12 l/min and power requirement starting from 1.5 kW.

RENA Pro D-series

The D-series is used for applications where the C-series does not cut it. These can be larger industrial applications such as VOC removal in paint & coating industries or heavily contaminated air streams with H2S & mercaptans e.g. wastewater or biogas

RENA Pro E-series

The most powerful RENA Pro ozone systems that we deliver for air applications. The ozone capacity reaches up to 480 g/h, which may be required in very intense and grand industrial applications with high flows and/or pollutant concentration.

RENA Pro X

The RENA Pro X is a custom-made solution that is suitable for especially demanding applications where more ozone capacity than the E-series is required. Based on the requirements, the ozone capacity can reach up to 3 kilograms per hour. As with the other series, it includes full customizability in terms of accessories such as monitoring, HMI and oxygen concentrators.

What is the right solution for you?

The RENA Pro can be utilized in many commercial or industrial applications requiring ozone treatment. The important part is to properly find the correct model and version for your application.

Below you can find our general sizing guidelines for the RENA Pro solutions.

[High amount of pollutants] [Low amount of pollutants]
ModelAir flow [m3/h]Air flow [m3/h] 
A-series0 - 5000 - 2,500
B-series500 - 6,0002,500 - 30,000
C-series6,000 - 12,00030,000 - 60,000
D-series12,000 - 18,00060,000 - 90,000
E-series18,000 - 24,00090,000 - 120,000

These guidelines were made under the assumptions of same pollutants and available contact time.

To ensure the optimal solution for a certain application, several parameters are required, such as:

  • Air flow (m3/h)
  • Type of pollutants (VOCs, sulfur, ammonia, microorganisms etc.)
  • Concentration of pollutants (ppm)
  • Available space on-site (floor area & possible height-restrictions)
  • Contact time (existing piping/ventilation)
  • Requirements from customer (odor reduction or similar demands)

For more stringent requirements and rigorous conditions, the RENA Pro can be complemented by other technologies such as UV-C Air 515 (AOP) or Nodora Odor Removal to reach your removal demands.
