FEATURES of PET Drying Machine

1. P.I.D temperature controller to accurately control regenerative temperature.

2. Adopt Japan Nichias molecular sieve honeycomb rotor which ensures good stable dehumidifying effect.

3. Detachable cooler is equipped for over-sized model, easy for maintenance and keeps a low return air temperature.

4. High density return air filter ensures no contamination to the honeycomb.

5. Temperature indication function for dehumidified outlet air temperature.

6. Efficient oil filter is optional, 99% of oil can be removed, thus product quality can be greatly improved.

7. Dew point of air after dehumidified can be lower than -40^oC.

8. For Models below ORD-400H, air-cooling is optional ensures low energy consumption and high efficiency.

APPLICATION of PET Drying Machine

ORD-H series rotary honeycomb dehumidifiers are mainly used to dry hygroscopic engineering plastics or regrind materials. Under ideal conditions, the dew-point of dehumidified dry air can be lower than -40^oC, the largest of which can provide dry air up to a quantity of 4,000 m³/hr.

WHAT IS “HONEYCOMB ROTOR”?

The main part of honeycomb rotor is made by ceramic fiber and organic additives, sintered under high temperature with molecular sieve or silica gel as basic material to bond together with inside of honeycomb to form the honeycomb-like structure. Unlike common desiccant or rotary molecular sieve, then, when aging, will produce dust, followed by process air to drying hopper, to pollute plastic material. Honeycomb rotor offers unlimited long service life and can be cleaned and not like usual molecular sieve which is easy to get saturated or requiring regular replacement. The moisture of return air is quickly absorbed by molecular sieves when passing through numerous holes within honeycomb rotor. So when coming out of rotor, can form low dew-point air. Regenerating and dehumidifying have similar principle and run simultaneously. The only difference is that the two process winds are in opposite direction.

Notes:

“*” stands for drying heater is optional for working with “optical” hoppers.

Application Cases of PET Drying Machine

Honeycomb Rotor cleaning steps:

1) Use a vacuum-cleaner with brush to suck up the dust on rotor surface.

2) Blow off the dust in the rotor channels with compressed air.

3) If there is dirt sticking to the channel walls inside the rotor, cleaning steps as follows:

a. Saturate the rotor by blowing humid air (higher than 60% RH) through the rotor without having regeneration circuit on. This can be done by just turning the regeneration heater off and still have the process blower running if process air has high humidity. If the process air is too dry try, to put a humidifier in the air stream. Do this for one hour.

b. Depending on the character of the dirt, sink the rotor into water with cleaning agent in it (PH value 3~2 liquid is applied to silica gel, PH value 7~10 applied to molecular valve). Greasy dirt should be put into a detergent solution with xy lene. 15 minutes cleaning is suggested.

c. Take the rotor out of the liquid and let it rest with the channels vertically for 5 minutes so the liquid can run out.

d. Blow off the residual liquid in the channels with compressed air.

e. Put the rotor back into the dehumidifier and run the unit with regeneration circuit (the regeneration temperature between 50^oC and 60^oC) on for at least one hour.

Note:

1. Note that in the dry air and wet air outlets, there will be high concentrations liquid out for some time. If a solvent has been used, there will be a residual smell for several days.

2. For some dirt which is greasy and sticky in the rotor, 100% elimination is impossible. The only one thing you can do is to replace the rotor. For the cleaned rotor performance can only be recovered partly.
