Desiccant Dehumidification Rotors


Desiccant Dehumidification Rotors
  Jiangyin SAT Air Treatment Equipment Co., Ltd, a joint venture company jointed with Chinese, Swedish and Thai partners, is a professional manufacturer to produce desiccant dehumidification rotors and cassettes. The rotor media is directly imported from the Swedish partner, Proflute AB. The rotors and cassettes will perform well in most environments and applications.

Desiccant rotor properties:

1. Highest desiccant content
  The PPS rotor has a very high, 82%, active Silica Gel content. It can be used for most environments and applications.
The PPM rotor has a very high, 37%, Molecular Sieve content and 45% Silica Gel content. It will perform well when the entering air is dry and/or hot or when the environment is alkaline. It is also suitable when the application calls for a low dew point.
The PPH rotor has a very high, 81%, active Silica Gel content, 2% Lithium Chloride, <0.1% additive to restrain microbiological growth. It is designed for use in the environments where enhanced bacteria resistance properties are required.

2. Excellent fire resistance
  The rotor media provided by Proflute AB has been tested according to ASTME test E-84 and achieved a flame-spread index of 0 and a smoke index 0.

3. Unique moisture absorption
  The density of dry media is approximately 240 kg/m3. The media can pick up approximately 40% of its dry weight as moisture in humid environment.
There is no limit for how high relative humidity the rotor can stand as long as the droplets are not introduced into the rotor during operation. The PPH rotor should not be exposed to a relative humidity exceeding 95% when not in operation.

4. Water washable
  The PPS and PPH rotors can be washed in the water with weak non-alkaline detergent. The PPM rotor should be washed with weak alkaline detergent.

5. High surface strength
  The surface compression strength of the rotor is more than 200 kPa.

6. Variety in construction
  The various kind of rotor construction could be made according to the customers’ requirement, such as selection of raw material of the metal parts and with or without flange etc. For the large rotors, the knockdown construction will be very convenience for transportation and assembly on site.

  On request, SAT can produce replacement rotors in different sizes to fit most existing dehumidifiers.
  The capacity, pressure drop and other characteristics of the SAT rotors can be easily calculated using Proflute computer software program which could be distributed to all regular customers.
The rotor cassettes have the following advantages:
1. The welded frame provides a rigid construction.
2. Laser cut for maximum accuracy.
3. The imported VITON seal has lower friction and longer working life.
4. The imported mini-motors and driving belts enable rotors reliably run. The chain driving system has stable run speed and non-maintenance for a long period.
