Automatic PLC Silica Gel Desiccant Dehumidifier , Microwave Drying Equipment


Quick Detail:


Microwave Drying Equipment ,  Silica Gel Air Purifier and Dehumidifier

  1. High moisture removal.
  2. Suitable for low temperature and RH process.
  3. Could be usded together with air conditioner.
  4. Start with domestic first rotor dehumidifier,
  5. With 30 years professional theoretical and practical experience in dehumidifier field
  6. Draw up the  national military standard and industry standard of dehumidification equipment



Except the desiccant wheel, ZLB series low humidity dehumidifier also equipped with pre and after cooling coils. It process with and dehumidify normal temperature air, it is specialized dehumidifier for normal temperature and low humidity process environment. As follow are their major characteristics:

  1. Main components: desiccant wheel, reactivation fan, reactivation heater, reactivation filter, , pre-cooling, post-cooling,heating coil,pre-filter ,medium filter and HEPA and cabinet.
  2. The cabinet is made of aluminum alloy, it is strong, compact, anti-corrosion, and it is anti-“cold bridge” which can help avoid condensation.
  3. The cabinet is double insulation panel structure with high density polyurethane insulation material inside(The inner plate of HEPA select 304Stainless wire drawing board), it is insulation, anti-corrosion, sound proof, fire proof and strong.
  4. The dehumidifier select PROFLUTE silica gel desiccant wheel from Sweden.
  5. Select SHANGHAI GENERAL centrifugal fan, its impeller and vent was plated with anti-corrosion coating, it’s strong and anti-corrosion. Select three-phase asynchronous motor, imported bearing, and level IP55 protection and level F insulation.
  6. Cooling coils select copper pipe and hydrophilic membrane corrugated aluminum fins, thickness of the copper pipe no less than 0.5 mm. Copper pipe thickness of heater no less than 0.75 mm, heating by vapor.
  7. G4 pre- filter, F8 medium effect air filter and H13 high grade filter to assure the air purity.
  8. Use control instrument,and humidity probe to control temperature and humidity. It is convenient to operate.
  9. Functions of electric controller:Parameter setting, operating status displaying and controlling, historical datarecording, wheel stop switch alarm, temperature and humidity limit alarm, reprocessing temperature limit alarm, filter clogging alarm, multi protection for temperature limit and over current and unbalance of phase.It can add proportional control valve for reprocess heating and former and latter surface cooler. To improve dehumidifier efficiency by optimizing function of each components.
  10. Main electrical components are Siemens, Siemens enjoy high high reputation for good quality, reliable operation.


  1. Intake air filter, silica gel desiccant wheel, double cold-water heat exchanger;
  2. Chain drive;
  3. Electric heating by stainless steel tube, or by copper tube aluminum fin;
  4. Efficient centrifugal fans, aluminum alloy frame, high pressure polyurethane and double foam layer cabinet, anti-cold bridge, electric multi-protection operation;
  5. Reliable PLC control system.
