In the plastics processing industry, dehumidifiers are key equipment to ensure product quality and production efficiency. During operation, various problems may be encountered. In order to help you get the most out of your drying equipment, here are four common problems and solutions.

Problem 1: The dehumidifier cannot operate normally

Throughout the plastic processing operation, the inability of the dehumidifier to be turned on or off can lead to production interruptions. The interruptions lead to inconsistent drying process, preventing plastic resins from evenly dried. Such problems are typically caused by electrical faults, incorrect control system settings, or faulty sensors. Solutions include checking the power supply for proper operation, ensuring the control panel is correctly set up, and regularly inspecting sensors and electrical connections to verify they are secure and functioning properly.

Problem 2: The dehumidifying effect is not optimal

Inconsistent airflow leads to uneven drying of plastic resins.

1. Check whether the filter screen of the dehumidifier is blocked or clogged, and regularly clean or replace the filter screen can improve air circulation.

2. Confirm whether the setting parameters of the machine are correct and ensure that the humidity adjustment function is normal.

3. Check whether there are any obstacles at the air inlet and outlet to ensure smooth airflow.

Problem 3: The dew point could not be reached

1. Check whether the return air temperature is too high (the normal return air temperature is below 40 degrees), check the cooling water regularly, and clean the Y-shaped net.

2. Check whether the filter is clogged and clean the filter regularly.

3. Check whether the hot air pipe is leaking and check the hot air pipe.

Problem 4: Temperature fluctuations

1. Check whether the temperature is set too high, it is recommended to set the temperature below 180 degrees.

2. Check whether the electric heating contactor is damaged, and the contactor can be replaced.

3. It may be that the electric heating pipe is damaged, it is recommended to replace the electric heating pipe.

4. It may be that the electric couple is bad, it is recommended to replace the electric couple.

Source Reliable Drying Equipment

Resin dryers and dehumidifiers are essential auxiliary equipment in plastic processing. Drying equipment ensures proper moisture removal from plastic resin before injection molding or extrusion. This process is crucial for maintaining high-quality finished products. While operational downtime from equipment errors is inevitable, investing in reliable drying equipment can significantly minimize these disruptions. By choosing dependable resin dryers and dehumidifiers, you can safeguard against production delays and maintain consistent product quality.
