Energy can represent over 70% of a compressor's lifecycle costs. Generating compressed air can account for more than 40% of a plant's total electricity bill. Most production environments have a fluctuating air demand depending on the time of day, week, or even months per year. With Adekom's VSD technology monitoring compressed air requirements, fluctuating demand no longer equals high energy costs.
ADEKOM's latest technology of Variable Speed Drive (VSD) Screw Compressor which adopts permanent magnet motor and controlled by frequency inverter is having the following features:VSD compressor precisely follows the varying air demand by adjusting motor rotation speed, this prevents unnecessary full load high current operation and energy consumed during unload operation of standard base load compressor;By adopting modern High Efficiency Interior Permanent Magnet (IPM) Motor Drive, Adekom LM series VSD compressor is having 6-7% more energy efficient than standard VSD screw compressor available in the market.;Especially under low loading running, optimal control range of IPM motor plays a significant role of superior energy saving effect.Thanks to the high energy efficiency of IPM motor under wide operating range, this inverter controlled variable speed drive screw compressor can achieve energy saving of 35% in comparing with standard base load compressor.
Feature
One Common Shaft Structure
Interior Permanent Magnet (IPM) motor is designed to be direct-couple connected with compressor airend male rotor internally with one common shaft structure without gear box or driving v-belts to guarantee 100% transmission efficiency without any loss.
High Efficiency Rare Earth Permanent Magnet Synchronous Motor
a. IPM motor constructed with neodymium iron boron permanent magnet materials can guarantee excitation loss will not happen even under high operating temperature up to 200oC. Services life is up to 15 years!
b. The specialized corona-resistance enameled cable with remarkable insulation performance is applied to stator coil for long service life.
c. One common shaft structure design, motor without bearing structure to guarantee 100% transmission efficiency.
d. No more greasing and replacement of bearings at regular interval.
e. High temperature protection via PTC/PT100 is available.
f. Wide adjustable speed range and high precision which lead to wider range of air capacity modulation.
g. Compact size, low noise level, low vibration and stable operation.
h. Special motor housing design, a choice of IP23 / IP54 / IP65 protection classes as option.
High Efficiency Oil Cooled Rare Earth Permanent Magnet Synchronous Motor As Option
Oil-cooled permanent magnet motor is double layer design which circulates lubricating oil from compressor oil circuit for cooling to realize low temperature operation under complete frequency range. This effectively prevents excitation loss due to high operating temperature and minimize power consumption of motor itself with traditional fan cooled design.
Oil-cooled permanent magnet motor is designed and produced in totally enclosed structure with IP65 protection class. Waterproof, dustproof and independent of operating environment to safeguard ingress of any dust and foreign particle to extend life span of motor dramatically.
Intelligent Control System
Multi-protection design with one (1) general fault reminder and ten (10) major faults protection. Choice of three (3) pressure value units (Mpa / Bar / Psi). Intelligent auto standby and auto sleep awaking function is available. Target pressure can be set for precise pressure control. Reserve of adequate dry contacts for air dryer on/off control and pre-heating function.
Specialized Frequency Inverter For IPM Motor
a. High frequency line reactor is equipped as standard to reduce high frequency output and prevent external magnetic field interference.
b. Peak current during start-up is minimized to achieve soft starting stably.
c. Saving the cost of power supply equipment.
d. Special ventilation design to avoid the risk of high e. Filtration mat is fitted as standard with surface coating treatment on circuit board to realize dust and dirt resistance and anti-moisture effect.
f. Follow CAN standard protocol and strictly comply with cable specification for hardware, good anti-noise interference capability.
g. Fast-tracking on pressure changes, pressure fluctuation is controlled within ± 0.01Mpa, to match precisely with the system air demand by outputting the optimal frequency/speed.
