[Product Introduction]

DY-SLD80，The dew point generator in this system realizes dew point adjustment based on the principle of shunt method. Gases with different dew point temperatures can be obtained through different ratios of dry and wet air flows. This method can use multi-stage split matching according to actual needs to generate the desired dew point value gas source. Our company provides a super dryer that can reduce the dew point to below -60°C (-80°C) and provide a drying air source, so the dew point value can be adjusted arbitrarily between -60°C (-80°C) and 20°C. , and can achieve fully automatic and rapid control.
