Gas-Cooler-Series for Gas Analysis | Fresenius Umwelttechnik

Gas Cooler Series

#1 best gas sample cooling system for gas analysis processes on the market

The best price, the lowest weight, the best product

When it comes to reliable gas sample conditioning, the RCI gas cooler series offers you the best price-performance ratio on the market. With their low weight and compact design, they are easy to install. The RCI gas coolers reduce residual humidity to just 0.86% by volume and keep the dew point stable at 5 °C, reliably protecting your analytical equipment from corrosion and contamination. Our gas coolers are particularly efficient.

Thanks to the robust construction made of durable materials such as Duran glass or steel and PVDF, these gas coolers are easy to maintain and durable – ideal for use in a wide range of environmental conditions.

FAQ

What is the difference between the RCI 500, RCI 700 and RCI 100 gas coolers?

  • RCI 500: This gas cooler comes in a slide-in housing for a system cabinet and processes a sample gas flow. It is ideal for applications where effective cooling and drying of a gas flow is required.
  • RCI 700: The RCI 700 also comes in a slide-in housing and is designed to process two sample gas flows.
  • RCI 100: This compact gas cooler is designed for floor or wall mounting and is ideal if no system cabinet is required. It processes one gas flow.

All devices offer a maximum cooling capacity of 90 kJ/h and a volume flow of up to 260 l/h per sample gas flow.

What does the washout effect mean?

In measurement technology and gas conditioning, the washout effect refers to the undesirable washing out of gas components by moisture or liquids.

  • When removing moisture, water-soluble components can also be washed out.
  • This can falsify the concentration of certain gases in the measured sample because they are partially removed or attenuated.
  • This leads to inaccurate measurement results and can falsify the analysis.

Thanks to our expertise and effective drying of the gases, the washout effect can be minimized with our gas coolers so that the original gas composition remains as unchanged as possible and precise measurement results are achieved.

Which industries benefit from the RCI 500, RCI 700 and RCI 100 gas coolers?

These gas coolers are used in a variety of industries:

  • Process industry
  • Pharmaceutical industry
  • Refineries
  • Recycling plants
  • Environmental analysis
  • Laboratories

Gas coolers play a central role, especially in areas where precise measurements and gas conditioning are required.

How easy is it to maintain these gas coolers?

Maintenance of the gas coolers is simple and user-friendly. The heat exchanger is made of durable Duran glass and can be easily removed for cleaning purposes. Additionally, there is an optional peristaltic pump for condensate drainage, which can also be easily maintained. This ensures a long service life and reliable operation.

How high is the residual moisture after cooling?

The residual moisture of the RCI 500 and RCI 700 gas coolers is only 0.86 % by volume, which corresponds to a dew point of 5 °C.

What interfaces do the gas coolers offer?

The RCI 500, RCI 700 and RCI 100 models have various modern interfaces for easy integration into existing systems:

  • Standard: RS232 interface
  • Optional: Profibus DP, Modbus TCP, Profinet, Ethernet IP
  • Configurable analog outputs: 4-20 mA for a flexible application.

Is there a warranty on the gas coolers?

The gas coolers are "Made in Germany" and are subject to strict quality controls. You can rely on a long service life and reliable service. You can find out more about the warranty and after-sales service on our service page and via our contact form.
