Recently, the after-sales engineering team of Shanghai Yuzhen successfully completed the installation and commissioning of a Taiwan Hanbell 75KW two-stage permanent magnet variable frequency screw air compressor system at a packaging container factory of United Arab Emirates. The system passed acceptance testing on the first attempt, winning high praise from the customer.

The customer's blow-molding, spraying, and other processes demand extremely high standards of compressed air stability, cleanliness, and energy efficiency. The old equipment was inefficient and often delivered air containing moisture and oil, affecting product quality. For this upgrade, they chose our Hanbell 75KW two-stage permanent magnet variable frequency air compressor, which saves over 30% energy. The post-treatment system includes an air receiver tank, a refrigerated air dryer, and three stages of precision filters, all strictly complying with ISO 8573-1 standards.

Now let's take a look at the advantages of Hanbell's two-stage permanent magnet variable frequency screw air compressor.

Parameter	Hanbell Two-Stage Permanent Magnet VFD Screw Air Compressor	Conventional Air Compressor (Fixed Speed / Single-Stage VFD)
Energy Efficiency Level	Entire series exceeds national Grade 1 standard by 10%–15%	Mostly Grade 2 or Grade 3; older units may be below Grade 3
Energy Saving	30%–45% energy saving compared to traditional fixed-speed units; about 10% more saving than ordinary VFD motors	Fixed-speed units waste significant energy during unloading; ordinary VFD units have limited efficiency improvement
Starting Current	Soft start, no inrush current, no special grid requirement	Fixed-speed direct start: high inrush current (5–7 times rated current)
Noise Level	Two-stage compression, low-speed operation, optimized rotor profile – significantly lower noise than single-stage	Single-stage compression, high-speed operation – generally higher noise
Maintenance Cost	No belts or other wearing parts; leak-proof hard-piped oil circuit – long-term maintenance-free	Regular replacement of belts, coupling rubber elements; piping joints prone to oil leakage
Application	Best for fluctuating air demand (e.g., multi-shift, seasonal production) – significant energy saving advantage	Suitable for stable air demand; high energy waste when demand fluctuates

On site, the engineers verified power supply, ventilation, and foundation conditions, optimized the cooling air duct, and used stainless steel piping to eliminate leaks. They strictly followed pressure vessel regulations to confirm the effectiveness of safety accessories. The commissioning process was carried out in three phases: no-load operation, loaded operation, and continuous running.

One week after the system went into operation, the customer reported lower noise levels, reduced electricity bills, and no more oil spots or water stains on sprayed products, with a decrease in reject rates. The Yuzhen engineers were not only highly skilled but also trained the customer's operators and left the site clean and tidy. The customer said they feel "very reassured."

The success of this project highlights Shanghai Yuzhen's professional capabilities in "compliant design, standard installation, and full-service closed-loop support.
