The air from the atmosphere is compressed by the main blower and transferred to a dehumidifier, then remove most moisture by water cooling and chilling, after then the air goes to silica gel for deep de-humidification, and finally gets dry air with dew point of -60℃. The flow rate of dry air (Nm3/h or kg/h) is controlled by the speed of the main blower (through the orifice flow meter and main blower VFD).
Features: The air cooling fin type heat exchanger uses SS304 as the fin plate and tube, the working life is much longer than the copper tube and aluminum plate.
