Overview
The Peltier Gas Cooler CS-7A is designed for dual-channel sample gas conditioning in gas analysis systems such as CEMS (Continuous Emission Monitoring Systems).
It cools high-temperature and high-humidity sample gas through semiconductor (Peltier) cooling technology, enabling efficient moisture condensation and removal. This helps ensure stable gas conditions for accurate and reliable analysis.
With its dual-channel configuration and robust performance, the CS-7A is ideal for applications requiring simultaneous gas sampling and continuous monitoring.

- Power plants
- Chemical processing plants
- Cement production
- Steel and metallurgy industries
- Environmental monitoring systems
Why Sample Gas Needs Cooling
In gas analysis systems, sample gas is often hot and saturated with moisture.
Without proper cooling and condensation:
- Moisture can damage analyzers and sensors
- Measurement accuracy can be significantly reduced
- Condensation may occur inside pipelines and instruments
- System stability and reliability are compromised
The Peltier Gas Cooler CS-7A removes moisture at the source by cooling the gas and condensing water vapor into liquid, ensuring optimal conditions for downstream analysis.
How It Works (Peltier Cooling Technology)
The CS-7A uses semiconductor (Peltier) cooling to rapidly reduce the temperature of incoming sample gas.
The process works as follows:
- Hot and humid sample gas enters the cooling chamber
- The Peltier module lowers the temperature of the chamber
- Water vapor condenses into liquid droplets
- Condensed water is removed through the drainage system
- Conditioned gas exits to the analyzer
This physical condensation process ensures efficient moisture removal without the need for complex drying systems.

Frequently Asked Questions
What does the CS-7A sample gas cooler do?
It cools sample gas so moisture condenses and can be removed before the gas reaches an analyzer.
What does dual-channel mean on the CS-7A?
The CS-7A is configured to condition two sample-gas channels in one compact unit, subject to the specified total operating limits.
What is the rated sample flow?
The rated sample-gas flow is 10 L/min total across both channels under specified operating conditions; it is not 10 L/min per channel.
What applications suit the CS-7A?
It suits continuous emissions monitoring, multi-stream gas analysis and laboratory sample conditioning. Browse the Peltier sample gas cooler range.
