Efficient air intake valve
B&D's efficient intake valves use hydraulicregulating mechanism instead of pneumaticregulating mechanism, which eliminatesperiodic replacement of pneumaticcomponents and reduces unnecessarydowntime and maintenance costs.
lt controls the loading and unloading througha combination of air intake and exhaust combination valve, which is simple andreliable.
Durable compression module
Efficient twin screw two-stage compressionmodule is with cast iron housing and is drivenby synchronous gear. B&D uses a pair ofthrust bearings to replace the balanced pistonsto withstand the axial force and improve theairend operating reliability.
Advanced intelligent control system
The intelligent control system is with perfect self-diagnosis,alarm,interlock shutdown andmonitoring functions, and able to save the fault cause and components in memory.
The compressor control panel is in backlight LED display and with touch button,with completefunction and simple operation. It could configure three controlling methods according to user'sdemand, i.e. local, remote and interlocking control. With the standard configuration of RS485interface to support MODBUS RTU communication.
Excellent rotor coating
The coating is to protect rotors againstcorrosion, reduce clearance between rotorsand improves efficiency.
Multiple layers of the composite coating withdifferent components are realized after severalsintering and running-in.
With rich experience in the development anduse of coating technology , the latest coatinghas been tested with a variety of chemicals,the temperature resistance is up to 270 degreeCelsius,which ensures the reliability anddurability of the rotors.
Permanent magnet motor + Inverter
The mechanical efficiency of efficient permanent magnet variable frequency motor is6%-8% higher than that of traditional asynchronous motor. B&D is the earliest manufacturer of using permanent magnet frequency conversion technology in the fieldof air compressor, which is with advanced technology and reliable performance. Withthe help of permanent magnet motor + Inverter, it makes the output pressure stable, andkeeps running in the high efficiency area, and the energy saving is even up to more than35%.
With the motor of protection grade of IP55 or above to prevent dust and other particlesfrom entering into the motor.
Always continuous and stable operation under harsh ambient temperature conditions.
Excellent and reliable coolingsystem
The operating environment of the compressoris designed according to the harsh high temperature and high humidity workingenvironment.
All the air or water cooling systems of B&Dcompressors are designed according to theambient temperature of 46 degree Celsius,they all can realize continuous and stable operation under harsh ambient temperatures toavoid high-temperature shutdown.
●Cooling module of air-cooled unit: It isconfigured with stainless steel pre-coolerwith high temperature resistance and
aluminum brazed plate fin heat exchangerwith good heat exchange effect, resistantto heat shock, and suitable for occasionswithout cooling water.
●Cooling module of water-cooled unit: It isconfigured with stainless steel shell-and-tube heat exchanger. The wateris in the tube pass and air is in the shellpass, which is good in cooling effect andeasy to clean.
