Fresenius Umwelttechnik GmbH

Founded 30 years ago as Fresenius Umwelttechnik GmbH, we are a family business and former subsidiary of INSTITUT FRESENIUS, drawing on 175 years of company history and expertise in chemical analytics and services. Greentech Made in Germany for a sustainable future worldwide – we bring our innovative technologies from the heart of Germany to the world, ensuring precision and reliability for over three decades.

As a leading manufacturer of gas analyzers and process gas measurement systems, our engineers and scientists develop cutting-edge solutions tailored to a wide range of industrial applications. Whether you're monitoring biogas in renewable energy systems, controlling emissions in the cement industry, or ensuring safety in hydrogen production and pharmaceutical gas monitoring, our instruments deliver precise, reliable results. With long-term stability and continuously reliable operation, our products are used worldwide in critical applications like environmental gas monitoring, wastewater treatment plants, and biogas plant monitoring.

Our comprehensive portfolio includes multi-gas analyzers, designed for online gas analysis and gas composition monitoring, supporting industries in their pursuit of efficiency and sustainability. We employ advanced technologies such as NDIR (Non-Dispersive Infrared) technology, electrochemical sensors (EC), and Tunable Diode Laser Spectroscopy (TDLAS) to provide precise methane (CH4), hydrogen sulfide (H2S), carbon dioxide (CO2), and oxygen (O2) measurements. Our stationary gas analyzers offer reliable online measurements in industrial processes, while portable gas analyzers ensure flexibility for field applications.

To guarantee maximum safety and compliance, our systems are equipped with ATEX-certified flame arrestors for explosion safety monitoring (UEG) and include features like automatic zero-point correction, cross-sensitivity correction, and long-term stability. In addition, we offer gas cooling and conditioning solutions, including gas coolers, heated gas probes, and automatic condensate drains, ensuring accurate gas sampling even in challenging conditions such as high moisture environments.

Our solutions are fully integrated with modern data communication systems, offering digital communication interfaces such as RS232, Modbus TCP, and Ethernet, along with analog outputs (4-20 mA) for seamless integration into existing industrial systems. We provide remote monitoring, data logging, and process data visualization through OPC UA connections and our online service platform. These features ensure that your data is always available, secure, and easy to interpret, helping you maintain control and optimize your processes.

At Fresenius Umwelttechnik, we are committed to delivering cost-effective gas monitoring solutions that are easy to operate, feature modular designs, and require minimal maintenance. Our instruments are designed with Plug & Play functionality, ensuring quick setup, touchscreen interfaces for intuitive control, and a long service life, making them the go-to choice for industries that demand high accuracy and high precision in their gas detection systems.

At Fresenius Umwelttechnik, our foundation is built on quality, customer orientation, and innovation. We design and produce state-of-the-art gas analyzers and environmental monitoring systems that set benchmarks in precision and reliability. Every decision is driven by a dedication to sustainability and long-term client success. We listen closely to our customers, tailoring process gas measurement solutions to meet their exact needs while remaining at the forefront of technological advancements. Our focus on safety, efficiency, and continuous improvement ensures that we lead the market in gas composition monitoring and environmental safety.
