Handling High Temperature Issues in Screw Air Compressors

Handling High Temperature Issues in Screw Air Compressors
October 24, 2023

Screw air compressors are widely used in various industries for their efficient and reliable performance. However, excessive temperature can sometimes pose a challenge, affecting the compressor's efficiency and lifespan. In this article, we will explore the causes of high temperature in screw air compressors and discuss effective solutions to mitigate this issue.

Causes of High Temperature:

1. Inadequate Lubrication: Insufficient or improper lubrication can lead to increased friction, resulting in elevated temperatures within the compressor.

2. Dirty Air Filters: Clogged or dirty air filters restrict the flow of air, causing the compressor to work harder and generate more heat.

3. Overloading: Overloading the compressor beyond its capacity can strain the system, leading to excessive heat build-up.

4. Malfunctioning Thermostat: A faulty thermostat may fail to regulate the compressor's temperature properly, causing it to overheat.


Effective Solutions:

1. Regular Maintenance: Implement a comprehensive maintenance schedule to ensure proper lubrication, timely filter cleaning/replacement, and overall system inspection. This will prevent the accumulation of dirt and debris and maintain optimal working conditions.

2. Correct Lubrication: Use high-quality lubricants recommended by the manufacturer to minimize friction and dissipate heat effectively. Follow the manufacturer's guidelines for lubrication frequency and quantity.

3. Proper Ventilation: Ensure adequate ventilation around the compressor to prevent heat accumulation. Clear any obstructions and ensure airflow is unrestricted, allowing heat to dissipate efficiently.

4. Load Management: Avoid overloading the air compressor ndustrial by carefully monitoring and adjusting the workload as per the manufacturer's specifications. This will prevent excessive strain and minimize temperature issues.

5. Thermostat Calibration: Regularly check and calibrate the thermostat to ensure it accurately regulates the compressor's temperature. If a malfunction is detected, repair or replace the thermostat promptly.



Maintaining optimal operating temperatures in screw air compressors is crucial for their efficient performance and longevity. By addressing the underlying causes and adopting appropriate solutions, operators can effectively manage high temperature issues. Regular maintenance, correct lubrication, proper ventilation, load management, and thermostat calibration are key steps to mitigate excessive heat generation. Remember, a well-maintained compressor will not only improve productivity but also reduce the risk of costly repairs and downtime.
