Low Temperature Desiccant Rotor Dehumidifier , Humidity Absorber
- High moisture removal.
- Suitable for low temperature and RH process.
- Could be usded together with air conditioner.
- Start with domestic first rotor dehumidifier,
- With 30 years professional theoretical and practical experience in
- Draw up the national military standard and industry standard of
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:
- Main components: desiccant wheel, reactivation fan, reactivation
heater, reactivation filter, , pre-cooling, post-cooling,heating
coil,pre-filter ,medium filter and HEPA and cabinet.
- The cabinet is made of aluminum alloy, it is strong, compact,
anti-corrosion, and it is anti-“cold bridge” which can help avoid
- 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.
- The dehumidifier select PROFLUTE silica gel desiccant wheel from
- 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.
- 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.
- G4 pre- filter, F8 medium effect air filter and H13 high grade
filter to assure the air purity.
- Use control instrument,and humidity probe to control temperature
and humidity. It is convenient to operate.
- 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.
- Main electrical components are Siemens, Siemens enjoy high high
reputation for good quality, reliable operation.
- Intake air filter, silica gel desiccant wheel, double cold-water
- Chain drive;
- Electric heating by stainless steel tube, or by copper tube
- Efficient centrifugal fans, aluminum alloy frame, high pressure
polyurethane and double foam layer cabinet, anti-cold bridge,
electric multi-protection operation;
- Reliable PLC control system.

- Peritek dehumidifiers are manufactured based on more than 30 years
of research and development. Have been used in space suit specific
cell production and become the most advanced satellite transmission
tower supporting equipment.
- Peritek dehumidifiers with R-DD optimal design, compared with the
general dehumidifier, can save energy more than 35%, and above 10%
with heat exchanger dehumidifiers.
- Dehumidification ability of Peritek dehumidifiers is great. Under
normal use, after closing down for 10 hours, system can restart and
reach the technical target in 30 to 60 minutes.
- We can provide users domestic initiative remote communication
interface according to your requirements, and the remote computer
operation and management system networking, superior to realize
- Peritek dehumidifiers adopt steel structure with plastic-sprayed
surface (Peritek self-owned patent, patent number: ZL 2008
Typical Application Fields:

The core component of rotary dehumidifier is the 8-16 hour spin in
turn densely cellular Conde desiccant wheel. The desiccant wheel on
both sides by high-performance silicon fluorine rubber seals along
the entire surface of the radial will be divided into 270 ° of the
treatment area and 90 ° of the regeneration zone, when the moist
air comes into the processing area, the air moisture in the
desiccant wheel was adsorbed into dry air, dry air meet the need of
dry place or gas production process
