The Bühler RC Series Sample Gas Cooler lineup is a state-of-the-art thermoelectric gas conditioning solution developed by Bühler Technologies (Germany). Unlike conventional compressor-driven gas coolers, the Bühler RC Series utilizes advanced solid-state Peltier element technology. This provides distinct advantages including ultra-compact dimensions, silent operation, complete elimination of chemical refrigerants, and virtually maintenance-free operation due to the absence of mechanical moving cooling parts.

The Bühler RC Series encompasses two primary model lines to address varying gas analysis system scales:

1. Bühler RC 1.x Series (Compact Footprint):
   • Bühler RC 1.1: Standard single heat exchanger model for 1 independent sample gas stream, ideal for space-constrained CEMS analyzer cabinets.
   • Bühler RC 1.2: Dual heat exchanger configuration supporting 2 independent sample gas paths or dual-stage cooling.
   • Bühler RC 1.2+: Enhanced variant of the RC 1.2 equipped with an intelligent electronic controller, digital status display, and visual dew point alarm indicators.

2. Bühler RC 3.x Series (Higher Cooling Capacity & Multi-Path):
   • Bühler RC 3.1: Higher cooling capacity design for 1 sample gas stream with elevated flow rates.
   • Bühler RC 3.2: High-capacity dual heat exchanger version offering reliable operation under elevated ambient temperatures.
   • Bühler RC 3.3: Top-tier multi-path variant featuring 3 independent heat exchangers (3 gas streams), tailored for complex multi-point sampling networks.

All Bühler RC Series models reliably maintain a constant sample gas outlet dew point at +5°C, effectively protecting sensitive downstream gas analyzers (NDIR, UV, CLD, Paramagnetic) from moisture damage.
