Note
The limits in the diagrams for the PTG, PTV respectively MTV are for a dew point of 40°C.
Heat exchanger
The energy content of the sample gas and, as a result, the required cooling capacity of the cooling system is determined by 3
parameters: gas temperature
The outlet dew point raises with increasing energy content (heat) of the gas. The required cooling capacity is determined by the
mximum acceptable level of the outlet dew point.
The following table shows cooler performance assuming the following conditions: =40°C and
Nl/h cooled air (i.e. after the moisture has condensed). With other dew points and gas inlet temperatures the values may differ.
Please contact one of Buhler's application specialists for assistance and further information.
