The SCD series "All-in-One" compact dryers combine drying, dehumidifying, and two-stage conveying functions in a single unit. They are suitable for drying hygroscopic engineering plastics, such as PA, PC, PBT, PET, etc. A honeycomb rotor is used in the dehumidifying section.
Features
- SCD series compact dryers are equipped with honeycomb rotor for dehumidifying. They have two kinds of design: fully integral and semi-integral, depending on the size.
- Suitable for drying hygroscopic engineering plastics such as PA, PC, PBT, PET, etc. Either H4 or H5 honeycomb-rotor can be specified according to requirement.
- Integration of dehumidifying, drying, and two-stage conveying functions in a single unit. Three-stage conveying is also available as an option.
- Material processing is controlled via microprocessor as standard with touch screen PLC control as an option for centralised and automatic operation.
- Dew-point monitor can be fitted to monitor and display dry air dew-point.
- Insulated drying hopper features dry air down-blowing and cyclone exhaust design. This improves drying efficiency and reduces energy consumption whilst maintaining a steady drying effect.
- Compact in size for ease of movement and space saving.
- Closed-loop conveying system eliminates the possibility of moisture re-absorption during material conveying.
- Equipped with pneumatic shut-off valve to ensure no material remains in the material line after each loading cycle.
- The dehumidifying section of SCD series features two condensers to ensure a low return air temperature and low dew-point.

Applications
This "All-in-One" Compact Dryers has integrated drying, dehumidifying, and two-stage conveying fuctions in a single unit. It is suitable for drying hygroscopic engineering plastics, such as PA, PC, PBT, PET, etc. A honeycomb rotor is used in the dehumidifying section, with a choice of two types of rotor:
- Models H4, under ideal conditions, can supply dehumidified dry air with a dew-point of -40°C.
- Models H5, under ideal conditions, can supply dehumidified dry air with a dew-point of -50°C.
