The Bühler PKE Series Sample Gas Cooler lineup is an advanced gas conditioning solution engineered with solid-state Peltier (Thermoelectric) cooling technology by Bühler Technologies (Germany). The PKE Series is specifically optimized to deliver high cooling performance within a compact physical footprint, making it ideal for integration into space-constrained CEMS analyzer cabinets or portable gas sampling systems.

The Bühler PKE Series offers flexible configuration variants tailored to specific gas conditioning demands:

1. Bühler PKE 42: Standard compact variant designed for standard gas flow rates, featuring high-quality heat exchangers for rapid moisture condensation and stable dew point output.
2. Bühler PKE 52: Enhanced cooling capacity model engineered for sample gas streams with high inlet moisture content or operating under fluctuating ambient temperatures.
3. Bühler PKE 62: High-capacity multi-stream model supporting dual gas paths (or two-stage cooling), capable of conditioning multiple independent sample gas lines simultaneously while maintaining pinpoint dew point stability.

All models in the Bühler PKE Series operate without mechanical compressors or chemical refrigerants, ensuring silent operation, zero mechanical vibration, and virtually maintenance-free longevity. The coolers maintain a constant outlet dew point at +5°C, featuring integrated temperature deviation status contacts to protect downstream gas analyzers from moisture damage.
