Customer Frequently Asked Questions (FAQ)

Q: How much electricity can the PLS low-pressure permanent magnet compressor save compared to the SLV low-pressure variable speed compressor?

A: In typical variable low-pressure load applications, due to the ultra-high efficiency of the permanent magnet motor under partial loads, the PLS can achieve an additional 8%-15% energy savings compared to the same specification SLV (induction variable speed). The larger the electricity consumption, the more substantial the additional cost savings.

Q: Are there any heat dissipation issues for the permanent magnet motor under low-pressure, high-volume conditions?

A: Absolutely not. The PLS series features a specifically optimized cooling duct and heat dissipation system for low-pressure, high-volume characteristics. Permanent magnet motors inherently generate less heat due to their high efficiency. Coupled with an efficient forced cooling design, this ensures the motor operates safely, efficiently, and stably over the long term.
