The Bühler EGK Series Sample Gas Cooler lineup represents a premium industrial-grade gas conditioning solution engineered and manufactured by Bühler Technologies (Germany). Designed as a vital component in Continuous Emission Monitoring Systems (CEMS) and process gas analysis setups, the EGK series lowers sample gas temperatures to a constant dew point, effectively condensing and separating moisture to protect sensitive downstream gas analyzers from water damage.

The Bühler EGK Series offers comprehensive configurations tailored to various industrial requirements:

1. Classification by Gas Paths:
   • Bühler EGK 1 / EGK 1 Ex: Single heat exchanger design for 1 independent sample gas path.
   • Bühler EGK 2 / EGK 2 Ex: Dual heat exchanger design for handling 2 independent gas streams simultaneously.
   • Bühler EGK 4 / EGK 4 Ex: Multi-path configuration supporting up to 4 independent heat exchangers for complex multi-point analyzer systems.

2. Classification by Environmental Safety Certification:
   • Standard Series (EGK 1, EGK 2, EGK 4): Designed for general industrial areas, laboratories, and safe CEMS shelters.
   • Explosion-Proof Series (EGK 1 Ex, EGK 2 Ex, EGK 4 Ex): Fully certified under international explosion protection standards ATEX / IECEx (Zone 1, Zone 2), specifically engineered for hazardous environments such as oil refineries, petrochemical plants, gas processing facilities, and chemical industries.

All Bühler EGK Series models feature high-performance compressor cooling systems combined with premium heat exchangers (BORO 3.3 Glass, Stainless Steel, or PVDF) to maintain an extremely stable dew point (+3°C to +5°C).
