The Bühler Technologies PEAC 12-57 Peltier Sample Gas Cooler is an advanced gas conditioning instrument engineered by Bühler Technologies GmbH (Germany)—a global authority in industrial gas analysis solutions. Utilizing state-of-the-art Peltier semiconductor cooling technology, the PEAC 12-57 rapidly condenses and removes moisture from sample gas streams, maintaining a precise and stable exit dew point (+3°C to +5°C) prior to entering sensitive gas analyzers.

Designed with a compact footprint, the Bühler PEAC 12-57 optimizes space utilization inside analyzer cabinets and sample gas conditioning panels. Operating on the thermoelectric Peltier principle without CFC/HCFC refrigerants, the cooler is environmentally friendly, operates with ultra-low vibration, and ensures high reliability for continuous 24/7 industrial duty.

The integrated heat exchanger in the PEAC 12-57 is fabricated from highly corrosion-resistant materials such as 316Ti Stainless Steel (1.4571), Borosilicate Glass, or PVDF, making it ideally suited for handling aggressive sample gas components including SO2, NOx, HCl, and H2S. An intelligent electronic controller maintains a consistent output dew point regardless of fluctuations in ambient temperature and inlet sample gas flow rates.
