The CEMS-PRE100CC is a high-efficiency compressor condenser engineered for accurate gas sample pretreatment. It ensures stable dew point, rapid cooling, and reliable moisture removal—perfect for emission monitoring systems (CEMS), power plants, and industrial gas analysis environments.
The CEMS-PRE100CC is a high-efficiency compressor condenser designed to support Continuous Emission Monitoring Systems (CEMS). Built to withstand harsh conditions with high temperature and humidity, this unit ensures stable and precise gas sample conditioning. With fast cooling, compact design, and superior moisture removal, the CEMS-PRE100CC is ideal for industrial applications such as electric power, chemical, and metallurgy.
In this article, we explore the features, technical specifications, applications, and key benefits of the CEMS-PRE100CC.

The factory-set output gas temperature is +4°C ± 0.1°C, which is quickly achieved thanks to the advanced cooling system. This fast stabilization minimizes gas volume changes due to temperature fluctuation.
The system provides a dew point of ≤ 5.0°C (at ambient temperature of 25°C), effectively removing water vapor from the gas sample. Heat exchanger tubes are available in glass and SS316 stainless steel, offering high durability and corrosion resistance.
Designed with stainless steel housing, over-temperature alarms, and PVDF connections, the unit ensures safe operation and long service life.
