Can permanent magnet frequency air compressors save power?
Everyone knows that air compressors are high-energy-consuming equipment. Even in some industries, the power consumption of air compressors accounts for more than 30% of the total electricity consumption. In order to save power, many customers choose the slightly more expensive permanent magnet variable frequency air compressor. This is also the main reason why more and more customers choose permanent magnet frequency air compressor. Does the permanent magnet frequency air compressor really save power? What is the principle of permanent magnet frequency air compressor power saving?
To put it simply, Permanent magnet frequency air compressor is the use of permanent magnet motor and frequency changer to achieve one plus one greater than two energy saving effect. So how much electricity cost can the Permanent magnet frequency air compressor saving?
Let's take one set 250KW (350HP) permanent magnet frequency air compressor as an example, and calculate it roughly according to the annual operation of 5000 hours:
Ordinary screw air compressor annual power consumption needs: 250 * 5000 = 1250000 kWh / year
The electricity cost per kilowatt is calculated according to 1 RMB. One set 250KW ordinary screw air compressor needs 1.25 million RMB in electricity cost per year.
The permanent magnet frequency air compressor has 30% energy saving than the ordinary screw air compressor. Then the permanent magnet frequency conversion air compressor can save the electricity fee of 375,000RMB per year for users, about $57690usd！！
Although the permanent magnet frequency air compressor is more expensive than the ordinary air compressor, considering the future use cost, the permanent magnet frequency air compressor is definitely the most cost-effective choice!
