Gas Cooler Calculator

Many areas applying extractive Gas analysis or dry basis measurement systems such as air emission testing equipment, CEM monitoring and stack test equipment, EPA method test equipment, process gas analysis and others, the sample gas needs to be ‘dried’ before it is fed into the analyser.

The sample drying is achieved by cooling the gas down below dew point. Consequently, any moisture will be condensed and removed from the system.

It depends highly on the gas composition or gas compositions and the ambient conditions, as they may vary significantly in CEM sampling, source testing or for example engine emission test, requires application specific cooling equipment. Thermoelectric chillers have their own strength and weaknesses, so have compressor chillers using a fluidic coolant.

Bühler Technologies is applying both technologies. The coolers are equipped with a cooling block in which heat exchangers are inserted. These heat exchangers are avalible in materials like stainless steel, duran glass or PVDF, with one or two individual gas paths. The temperature of the cooling block is regulated by the Bühler constant control system providing a very stable dew point even under varying ambiend conditiones. The coolers are maintenance free.

The product range includes coolers for hazardous areas (Atex Zone 1 and 2) and water cooled heat exchangers.

For condensate removal either peristaltic pumps or automatic condensate drains are available. Further accessories are available upon request; see respective data sheets for options.

As high energy efficiency is a major concern, modern calculation methods and system design is an inevitable request.
