How does an screw air compressor operate reliably?
First of all, there must be a strong heart to provide power energy (air end + motor). We adopt the German twin-screw air end technology design to ensure good sealing and stable air volume. At the same time, it is paired with a high-quality motor (the factory qualification rate of the motor is as high as 98%) to ensure a long design life for 10 years,
Then there must be good lungs to produce pure air (air intake system) using Ingersoll Randong-designed air inlet and outlet ducts to separate the incoming air from the incoming air to ensure that the oil content is low and reaches food-grade air.
Secondly, we also need a smart brain (controller) with a high-definition touch screen panel that allows you to easily control all the details of the air compressor. Everything is clear and easy to use.
Finally, if you want to upgrade your air compressor, then take a look at our variable frequency rotary screw air compressor.
It can save electricity for you while running smoothly, (permanent magnet motor + inverter). We all know that if you want to save electricity, you need to adjust the motor speed. Hengchaowin quotes the stable input of international frequency converters to save you more than 20% -30%of energy, which is the best choice for sustainable development.
Screw compressor Saving energy is making money
Hengchaowin rotary screw air compressor used germany technology screw(air end ) ,
The same intake valve designed by Ingersoll Rand,high Efficient IP54 rated motor,And quoted the high-efficiency inverter fromDenmark.
The air compressor can maintain a stable motor efficiency at any speed, so it is more energy-saving and power-saving.
