Sample gas coolers condition the sample gas of an analyzing system by passing it through a heat exchanger and cooling it down. Removing any moisture from the gas is a critical step in sample gas conditioning, accomplished by using suitable coolers to lower the gas temperature below the dew point, allowing water to condense. The dew point must be as stable as possible for a repeatable analysis result even when the ambient temperature varies. Sample gas coolers have broad applicability in the cement, petrochemical, steel, power generation, and process industries.
The Perma Pure Baldwin Hybrid Sample Gas Cooler combines the superior performance of Perma Pure’s Nafion™ based drying technology with the functionality of a traditional thermoelectric cooler. Powered by compressed air, this nonelectric cooler achieves dew points lower than 0?C, helping to prevent problems associated with condensation. The patented mechanical design is ideal for locations with limited or no access to power or other areas where a nonelectric product may be desirable.
