PPS Silicone Gel Rotor

The third generation Silica rotors are intended for use in dehumidifiers and desiccant cooling systems. The design is of third generation Proflute silica gel rotors and widely recognized for outstanding performance in most applications and environments.


The silica gel is produced in situ during the manufacturing process, and the PPS formula ensures improved dehumidification performance and energy efficiency. As a result, a dehumidifier with a PPS rotor offers more dehumidification for less running cost than a unit equipped with another rotor of the same dimensions. This is an important factor when LCC aspects (Life Cycle Cost) for a dehumidifier plant are evaluated.


Proflute holds unique manufacturing techniques of PPS rotors, well-defined and stable manufacturing conditions. This ensures and maintains a high level of repeatability in the process which in the long run guaranties a stable and high quality production output of world class rotors. The capacity, pressure drop and other process characteristics of the PPS rotors are easily calculated using our projecting software, which is available for all regular customers.

Apart from delivering rotors with standard dimensions and properties as outlined overleaf, Proflute can produce replacement rotors in sizes to fit most existing dehumidifiers.

Our offer to you is to provide rotors to fit your needs, with world class performance and dimensioned to your specific demands.

  • Highest desiccant content

    The PPS rotor has a very high, 82%, active Silica Gel content. It can be used for most environment and applications.

  • 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.

  • Unique moisture adsorption

    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.

  • Water washable

    The rotor can be washed in the water when the rotor is saturated in humid environment. The PPS rotor should be washed with weak non-alkaline detergent.

  • High surface strength

    The surface compression strength of the rotor is more than 200kpa.

  • 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.

Dimensions, standard rators

Diameter, mm Available depth, mm Shaft diameter, mm Delivered knock-down
100~350 50, 100 or 200 20 No
450~550 100,200 or 400 20 No
600~1050 200 or 400 20 No
1150~1950 200 or 400 30 Can
2000~3000 200 or 400 40 Yes

So many sizes of rotors can meet dehumidifier manufacturers’ demand and replacement demand for most existing dehumidifiers. The selection software provided by ProFlute can calculate the rotor’s dehumidification capacity, resistance and other characteristic parameter to assist customers to select suitable rotors according to different dehumidification demand.

  • Material composition

    • Very high silica gel contents – 82%
    • Low glass fiber contents– only 16%
    • Acrylic surface coating – remaining 2%
  • Fire resistance

    • ASTME E-84 tested:
    • Flame index – 0
    • Smoke produced – 0
  • Technical properties

    • No limit on high relative humidity (as long as no droplets are introduced in rotor during operation)
    • Rotor can be washed in water (with weak non-alkaline detergent after saturation in humid air)
  • Physical properties

    • Dry material density – ~240 kg/m3
    • Water vapour adsorption capacity >40%
    • Surface compression strength – >200 kPa

To part of customers we can supply the rotor cassette also. Our rotor cassettes have the following advantages:

  • The welded frame provides a rigid construction
  • Laser cut for maximum accuracy
  • The imported VITON seal has lower friction and longer working lift
  • The imported motors and driving belts enable rotors to run reliably. The chain driving system has stable running speed and non-maintenance for a long period.
