Gas dryer

Application example 2: When all volume of sample gas is usable for purge gas;

1) The purge outlet must always be open to the atmo-

sphere.

2) Ahighersamplepressureisadvantageous.Thepres-

sureshouldnormallybe0.1MPaatmaximumand0.05

MPaatminimum.Ifthepressureislow,anadequate

dehumidificationeffectmaynotbeobtainable.

3) The pressure gauge, when provided, is helpful for

monitoringtheoperationalstatus.

4) If drain occurs due to pressurization by the pump, it

shouldpartiallybebypassedwiththedrainseparator.

2.Dust should be removed by installing a filter of filtra-

tion accuracy 5µm or less before the dryer.Oil mist

3.If water drops enters the semi-permeable membrane

tube,onlythewaterpermeatesthemembraneandthe

salts dissolved in the water are precipitated to cause

clogging.Therefore,theflowpathshouldbedesigned

4.This dryer has a large drying capacity and can reduce

humidity, but cannot maintain humidity at a constant

levelbytheordinaryusage.

Forusingthisdryerasahumidityconditioner,theflow

rate, pressure and temperature need to be kept con-

stant.

5.This dryer is unusable for gases of alcohol, ketone,
