pke42气体冷却器

Accurate measurement of gases requires samples with stable dew points even under harsh ambient conditions.The PKE 42 cooling system consists of semiconductor Peltiercooling elements with an aluminum cooling block. Fitted intothe block is a removable, high-efficiency heat exchanger

made of stainless steel, DURAN-glass or PVDF with 1 or 2gas paths.The unit maintains a constant outlet dew point of 40 °F withan electronic controller. The temperature of the cooling blockis shown on an LED-display. The status is indicated by aflashing LED which shows high or low temperature alarmsand operates together with relay to halt the flow of sample gasin fail-safe mode.The relay maybe used to control the sample gas pump when the cooler reaches the desired temperature range.
