Overview
The Peltier Gas Cooler CS-5A is designed for 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 ensures that the gas entering the analyzer is dry, stable, and suitable for accurate measurement.
With its compact single-channel design and precise temperature control, the CS-5A is ideal for applications requiring reliable and continuous gas analysis.

- Ensure stable mounting to prevent vibration
- Keep sufficient space for airflow and heat dissipation
- Connect power supply correctly (220V AC)
- Ensure all gas connections are properly sealed
- Regularly check drainage system for proper operation
Applications
The Peltier Gas Cooler CS-5A is widely used in:
- CEMS (Continuous Emission Monitoring Systems)
- Power plants
- Chemical processing plants
- Cement production
- Steel and metallurgy industries
- Marine emission monitoring systems
- 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-5A 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-5A 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 via a built-in peristaltic pump
- Dry and stable gas exits to the analyzer
This physical condensation process ensures efficient moisture removal without the need for complex drying systems.
