Accurate measurements of gases require gas samples withstable dew points even under harsh ambient conditions.The EGK models provide a compressor-type cooling systemconnected to a cooling block. The cooling block evenlydissipates the heat thus supporting the highly efficient heatexchangers. The temperature of the cooling block isregulated by the .This system allows smooth regulation and eliminates thedisadvantages of the traditional on-off operating mode.The cooling block accommodates either a single stream or adual stream heat exchanger hence the cooler may serve twoseparate sample gas streams.Condensate is removed either by peristaltic pumps, by automatic condensate drains or condensate vessels.

The energy content of the sample gas and, as a result, the required cooling capacity of the gas cooler is determined by 3 parameters: gastemperature , dewpoint (moisture content) and flow v.
