How to solve the difficulty of oil-free air compressor starting at low temperature

Difficulty in starting oil-free air compressors in low temperature environments is a common problem. This is mainly due to the low temperature causing the lubricating oil inside the machine (for water-lubricated oil-free air compressors, the "lubricating oil" here actually refers to water or Water-based lubricants) become viscous, and possible battery performance degradation, slow response of electrical components and other factors. The following is a solution to the difficulty of starting the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group in a low temperature environment:

preheating: Before starting, you can use electric heating belts or heaters to preheat the air compressor to increase the temperature inside the machine. This helps to reduce the viscosity of the lubricant, making it easier to flow.

Improve lubrication: For water-lubricated oil-free air compressors, ensure that water or water-based lubricants suitable for low-temperature environments are used. In extreme low temperature conditions, you can consider adding antifreeze or using a preheating system to maintain the fluidity of the lubricant.

Check the battery and electrical system: Make sure the battery is fully charged and in good condition. Low temperature will affect the discharge performance of the battery, so it may be necessary to use a battery more suitable for low temperature environment. At the same time, check whether the connection and response of the electrical system are normal.

Use of starting aids: In extreme cold conditions, consider using starting aids, such as a starter motor heater or a starter capacitor, to provide additional starting torque.

Adjust the control system: For the variable frequency screw air compressor, the start-up process can be optimized by adjusting the parameters of the control system. For example, the frequency or voltage at startup may be increased to provide a greater startup torque.

Follow the manufacturer's recommendations: refer to the user manual and operating guide provided by the Shanghai Grankering Group for specific recommendations and precautions for cold start-up.
