Why Desiccant Rotor is Widely Used in Plastic Industry

During the manufacturing of plastic products, the ambient humidity has a direct impact on their quality. If the ambient humidity is relatively high, the plastic will not be easy to mold and is unlikely to meet the standard, which will affect not only the product quality but also the manufacturer's profit. Therefore, it is necessary to strictly control the humidity in the plastic manufacturing process. However, the characteristics of plastics make it rather difficult for general industrial dehumidifiers to control the humidity.

The less vapor in the air, the lower the dew point temperature. The research has shown that the quality of finished plastic products can be improved when the dew point is below -40°C. In such low-temperature environment, the moisture on industrial dehumidifiers or in workshops will frost and the machine will fail to dehumidify.

In the plastic manufacturing process, the engineers come up with more scientific and efficient humidity control solution for a rotary dehumidifier to control the dew point of environment and to reduce substandard products.

The common industrial dehumidifier is a refrigeration dehumidifier that cools the air, liquefies the moisture, and centralizes the condensed water. During this process, the equipment can easily freeze and unable to run. However, a rotary dehumidifier has a continuously rotating desiccant rotor to absorb moisture. The desiccant rotor is made of special heat-resistant composite materials. As the air passing by, the moisture can be easily to be absorbed. Compared to industrial refrigeration dehumidifiers, rotary dehumidifiers do not freeze and can run continuously without affecting the ambient  temperature.

Rotary dehumidifiers are the best choice.

To deal with the hydrophilicity of plastic polymer materials, Puresci collects and analyzes the original physical parameters based on the water absorption and dehydration curves of different plastic particles.

Then we use the results to optimize our production process to meet the specific requirements for different industrial senarios and to achieve energy saving. That’s how Puresci figure out customized solutions for our clients.

Puresci rotors are suitable for drying various types of plastic pellets.

We have desiccant rotors suitable for plastic dehumidification and other industrial applications. Please click to check our website www.purescirotor.com or you can send an email to ankie@puresci.com, wewill never disappoint you.
