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 which are well known as market leading products, and widely recognized for outstanding performance in most applications and environments.
The PPS family of rotors has higher contents of active silica gel than any other rotor in its market segment. 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.
To protect the integrity of our customers, Proflute holds patents on the unique manufacturing process of PPS rotors. The well-defined and stable manufacturing conditions makes it possible to closely tailor the amount and characteristics of the silica gel used in the rotors. 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.
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.
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.
- Very high silica gel contents – 82%
- Low glass fiber contents– only 16%
- Acrylic surface coating – remaining 2%
- ASTME E-84 tested:
- Flame index – 0
- Smoke produced – 0
- 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)
- Dry material density – ~240 kg/m3
- Water vapour adsorption capacity >40%

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.
