Dehumidifying Dryer
PET resin drying is the first step to have good quality bottles. Moisture must be taken out before injection. We always recommend to use dehumidifier which recycles heat to use energy wisely and to get PET dew point to -50°C or blow so that PET exhibits its optimum nature.
Most people choose one of the two options as shown below.
Option One - 3 in 1 Compact Unit
Features:
- Integration of dehumidifier drying and two-station conveying to form a compact design which is mobile and floor space saving.
- Microprocessor controller gives digital setting and display of drying temperature, loading time, 99-hour timer for auto start-up and fault alarm functions.
- Thermo expansion bypass valve balances the load to match specific processing. Two condensers installed to ensure low return air temperature as well as low dew-point.
- Insulated drying hopper to save energy.
- Closed loop convey design for dried material to avoid moisture re-absorption.

Note: The PET drying capacity on the table above is for reference only. The humidity of the certain area, the nature of specific PET resin, the working temperature and bottle application shall be considered to determine the actual capacity of each model.
Option Two - Pick up dehumidifier, hopper dryer and autoloaders individually
Following layouts are for different applications:
Layout A is for small capacity that the hopper dryer can be put on the injection machine. Layout B is for considerably big hopper dryer which is too heavy to be installed on the injection machine. Layout C is a central dryer system for large capacity production with multi-injection machines.
This option features free combination for variety applications. It mainly consists of three categories:

Principle of dual tower dehumidifier (click for larger image)
PET resin demands a steady low dew point dry air with constant drying temperature to achieve its residual moisture content to 0.02% or lower to exhibit its optimum physical performance and surface finish.

Note: Optional parts such as preheating timer, filters at the entry and/or air discharge, magnetic grill, floor stand and suction box can be selected upon request at extra charge.
Autoloader
Several types of autoloader, split or one-piece set, carbon brush or induction, 1 to 1 or 1 to 2 autoloader can be selected according to specific project. In some cases, both split and one-piece autoloaders will be required. For example, the Layout B, the first one-piece autoloader is for bringing material to the hopper dryer and the second split autoloader is for delivering dried material to the injection molding machine. The table below shows some models to selection.
