Compact and modular air filtration system
Nodora CAT™

The ultimate solution for efficient H2S removal

The Nodora CAT™ are modular, compact air treatment systems and solutions specifically designed to remove high and medium loads of H2S (hydrogen sulfide), taking into account airflow, pollution load, while retaining extremely low pressure drops compared to other air treatment units. The H2S removal system shares the same unique features as the Nodora ADS™ product series, including exchangeable cassettes and compatibility with ductwork.

The compact design and industrial-grade, high-performance odor treatment capabilities of the Nodora CAT™ open up new possibilities for planners and consultants.

Nodora CAT™ series

The Nodora ADS™ & CAT series can be configured in a variety of combinations. Units can be installed in parallel or in-line. The Nodora CAT™ series is specially designed for catalytic conversion of high hydrogen sulfide concentrations and is based on the same unique characteristics of Nodora ADS™. Nodora CAT’s™ H₂S conversion efficiency is superior to other solutions on the market and can be combined with Ozonetech turn-key ozone systems for H₂S removal if concentrations and air flows are high. Its robust stainless steel construction makes it suitable for a variety of on-site conditions.

The Nodora CAT™ series multi-unit installations can be configured in series or in parallel, depending on pressure drop or air flow capacity requirements. It can handle both continuous or intermittent flows with sustained performance. Our qualified engineers are always there to help you determine your requirements, appropriate placement, and the final selection of units or systems with the right capacity that will provide you the best cost of ownership.
