Page 9: Product Description
EGK 2A Ex 3 Product description 3.1 General description A sample gas cooler is used to lower the moisture content, thus the dew point of a sample gas. This is intended to on one hand lower measurement accuracies through volume influence, on the other to avoid for moisture to condense further along the measuring path and cause damage, particularly to the delicate measuring cell of the analyser. -
Page 10: Transport And Storage
EGK 2A Ex 4 Transport and storage The sample gas cooler must be transported in the original packaging or a suitable alternative. It must be transported upright. Never place it on its side during transport, as oil could otherwise leak from the compressor and enter the cooling circuit. This can result in cooler start-up problems or failure. -
