The material to be dried is kept on the tray. The hot air is continuously circulated and forced convection heating takes place to remove the moisture from the material. And simultaneously the warm air is ducted off.
- WEIBER Tray Dryers are double walled convection heated and cooled units. Outer body are constructed out of thick PCRC, pre coated corrosion resistant GI sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated. The inner construction is of stainless steel sheet of SS-304 grade). The gap between the walls is filled high grade mineral glass wool, which ensures maximum thermal efficiency in our ovens.
- Temperature control:
The temperature up to 200°C is maintained in the oven which is controlled by nanotechnology based microprocessor controller (HMI+PLC as an option).
- Air circulation:Triple walled back of unit is fitted with circulation fans for maintaining temperature uniformly throughout the ovens.
Features of Coaxial Circulation Fan:
- Vacuum impregnated stator winding with dr. back varnish under red baktol
- Non-hygroscopic.
- Best IR value
- Bright bar (EN - 8 class) shaft.
- Bush bearing of branded companies.
- Surge comparison testing in fans and pumps eliminates into turn short circulating of the stator.
- Pressure die-casted-rotor manufactured with zero error.
- Boats of high accuracy
- Temperature chart recorder/printer for printing graphs(optional)
These self-contained, easy-to-use recorders provide a permanent record of temperatures, using a precise, spiral-wound bi-metallic strip transducer. All models include an on/off switch, locking door and built-in slot for an optional tie-down cable and lock. All include one "AA" battery, pen, starter box of 60 charts and manual. All come standard with one-point NIST traceable Certificate of Calibration.
- Heating:
Indirect heating system is provided in our units, comprising of air heaters made of high grade Kanthal/Nichrome wires of suitable wattage. The warm air is evenly distributed throughout the oven through efficient motor fans ensuring very good temperature sensitivity.
