PRODUCT FEATURES
ENERGY SAVING
Ultra-low frequency speed control technology far surpasses standard VSD compressor systems. Capable of lower than 15Hz operation, this system is truly capable of constant variable pressure operation and significant energy saving.
HIGH RELIABILITY
USoft-start feature allows for little or no impact on the power supply system and marginalises mechanical wear and tear up on start-up Leakage is always present in any air system. At full pressure a good system can loose 0.2Mpa. Zerlion VSD machines can reduce that loss by up to 25% simply by supplying the air pressure that is required.
MUTE ENVIRONMENTAL PROTECTION
Advanced Vector variable frequency control reduces vibration and noise. The unit can be used without the requirement for a special room. This means saving of all resources required to install a machine in an external location such as pipe and power lines and land. Oil exhaust output is lower than 3ppm thus negating enviromantal impact.
ENERGY SAVING 30% & LONGER LIFE
Utilising frequency control for the cooling fan and drive motor allows for up to 30% energy savings. This translates into less frequent servicing of the screw compressor thus further significant savings are achieved over the life of the machine.
FEATURES
Intelligent Control System
Direct display of discharge temperature and pressure, operating requency, current, power, operating state. Real time monitoring of discharge temperature and pressure, current, frequency fluctuations.
The Latest Generation High Efficiency Permanent Motor
Insulation grade F, protective grade IP55, suitable for the bad working conditions. No gearbox design, motor and main rotor through the coupling directly connected, high transmission efficiency. Wide range of speed regulation, high precision, wide range of air flow regulation.
The Latest Generation Super Stable Inverter
Constant pressure air supply, air supply pressure is accurately controlled within 0.01Mpa. Constant temperature air supply, general constant temperature set at 85oC make the best oil lubrication effect and avoid high temperature to stop.
Wide Working Frequency Range To Save Energy
Frequency conversion ranges from 5% to 100%. When the user s gas fluctuation is large, the more obvious energy saving effect and the lower the low-frequency running noise, applicable to any place.
Small Start-up Impact
Use frequency conversion permanent magnet motor, start smooth and soft.When the motor starts, the current does not exceed the rated current, which does not affect the power grid and the mechanical wear of the main engine, greatly reduces the power failure and prolongs the service life of the main screw machine.
Low Noise
The inverter is a soft start device, the start-up impact very small, noise will be very low when start-up. At the same time, PM VSD compressor running frequency is less than the fixed speed compressor during stable operation, mechanical noise decreases very much.
