PM VSD Screw Air Compressor ZLS-150Hi+

Permanent Magnet Variable Frequency Low-Speed Series

Selection of Low-Speed Screw Rotors.Through long-term testing and research on screw rotors, we have found that the specific power of screw rotors first decreases and then increases as the main engine speed increases. There exists an optimal main engine speed that enables the screw compressor to achieve the best energy efficiency. Therefore, when designing the ZLS Hi+ series main engines, we select high-quality motors to match the main engines operating at the optimal speed, ensuring that each of our rotors works at its corresponding speed and thus achieves an excellent energy efficiency ratio.

Optimized head proportioning creates large displacement.Through long-term rigorous theoretical research and a large number of type tests, a solid technical foundation has been laid for the optimization of head proportioning and design. The ZLS-Hi+ air compressor series products adopt optimized head proportioning and system design, with a displacement that is 10% higher than that of compressors with the same power.

1.Dual inverter control  Through long-term testing and research on screw rotors, we have discovered that the specific power of screw rotors decreases first and then increases as the main engine speed rises. There exists an optimal main engine speed that allows the screw compressor to achieve the best energy efficiency. Therefore, when designing the ZLS Hi+ series main engines, we select high-quality motors to match the main engines operating at the optimal speed, ensuring that each of our rotors works at its corresponding speed and thus attains an excellent energy efficiency ratio.

2.Jaguar's Special Extra-Large Intake Valve.  Normally closed, extra-large caliber, ultra-low pressure drop; Low failure rate, extremely long service life.

3.Heavy-duty air filter.Unique air intake box system to prevent dust from entering the system; It filters fine particles in the intake air, ensuring the air quality entering the machine head and extending the service life of the main engine.

4.Jaguar Liquid Cooler.Adopting a high-efficiency cooler, it achieves excellent cooling performance; Even in harsh operating environments such as high temperature and high humidity, it can ensure the normal operation of the air compressor.
