Advantages
Checking the dew point
Reliable gas analysis depends crucially on controlling the dew point. The Gas Cooler RCI 100 ensures long-term stability of the gas samples, regardless of the ambient conditions. This gives you the consistently accurate measurement results that your systems depend on.
Maximum moisture reduction
Our expertise guarantees maximum moisture reduction while minimizing the washout effect to ensure precise and reliable measurement results.
Versatile use in various industries
Whether in the pharmaceutical industry, recycling plants or refineries - gas coolers such as the RCI 100 are indispensable wherever precise measurement results are required with a high moisture content in the sample gas flow. With its robust construction and modular design, it simplifies maintenance and ensures that your processes run smoothly.
Optimized performance and lower maintenance costs
Thanks to the minimization of residual moisture to just 0.86% by volume, the RCI 100 protects your sensors and analysis devices from contamination and damage. This leads to a longer service life of the devices, lower maintenance costs and minimized production downtime - which significantly increases the productivity of your operation.
Frequently asked questions
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.
- Components can be washed out when moisture is removed.
- 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 the 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. There is also a peristaltic pump for condensate drainage, which is also easy to maintain. This guarantees a long service life and reliable operation.
How high is the residual moisture after cooling?
The residual moisture of the RCI 100, 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.
