How does a desiccant wheel dehumidifier work?
A desiccant wheel with a grid of small air passages, similar to a large bundle of coffee straws, is impregnated with silica gel (the same silica that is used in the packets that keep shoes dry). The desiccant wheel rotates slowly through the different airflow zones of the desiccant, as it works to remove moisture.
When should you use a desiccant dehumidifier?
When you're faced with drying in cool temperatures or drying dense materials like hardwoods, brick, or plaster-and-lath construction, nothing beats the efficiency and power of desiccant dehumidifiers.
Description:
The Dehumidifier is specialized for normal temperature and low humidity process environment. Its major characteristics are as follow:
1. Main components: pre-filter, desiccant rotor, process fan, electric controller and cabinet.
2. The cabinet is made of aluminum alloy, and double insulation panel structure with high density polyurethane insulation material inside, strong, compact, anti-corrosion, and it is anti-“cold bridge” which can help avoid condensating.
3. The dehumidifier select PROFLUTE silica gel desiccant wheel from Sweden.
4. Select centrifugal fan, its impeller and vent was plated with anti-corrosion coating, it’s strong and anti-corrosion.
5. G4 rough effect air filters to assure air purity.
6. Use text display, temperature and humidity probe to control temperature and humidity. It is convenient to operate.

1. Air flow above 4000 without process fan, users can select.Note:
2. If regeneration heating type select steam, P=0.35~0.45MPa.
3. Larger airflow dehumidifiers can be customized.
Competitive Advantage:
1. 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.
2. 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.
3. 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.
4. 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 remote service.
5. Peritek dehumidifiers adopt steel structure with plastic-sprayed surface (Peritek self-owned patent, patent number: ZL 2008 0163177.3 2).
Work Principle:
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.
Typical Application Fields:
1. Warehouse, Library and Archives:
In low humidity environment, the goods, books and files will not be damaged for a long time.
2. Pharmaceutical Industry:
Widely used in processes need to control humidity in parametrical industries, for example, soft gelatin capsule, fluidized bed, tablet press, coating machine, tumble dryer, tray dryer and so on.
3. Electronics Industry, Lithium Battery
It is widely used for precision instrument manufacture such as electronic components, astronavigation component, lithium battery etc which needs strict control of moisture.
4. Chemical Fiber Industry:
Used with chiller, it can make the dew point below -40℃ to meet the drying environment for PET chip in the chemical fibre factory.
5. Food Processing Industry:
Used in dehydrated vegetables, chocolate, candy, chewing gum manufacturing, cube
sugar store,flour processing, fermentation, drying and other processes.
