Energy Saving Vertical Air Compressor / Screw Type Air Compressor 55KW

Vertical Air Compressor DETAILS

Vertical Air Compressor ADVANTAGES/FEATURES

• Advanced and energy saved spiral tooth type technology
• New-type 5:6 asymmetrical rotator tooth type
• German screw compressor with large rotator and low rotation speed
• Adopt top-level quality SKF taper-roller bearing imported with original packaging from Sweden

Integrated oil cooled pm synchronous motor

• Oil cooled permanent magnet motors adopt double layer design. The motors are cooled down by cycling lubrication oil of air compressors, so they can operate in low temperatures at all frequencies. Such motors have eliminated degaussing risks at high temperatures by breaking through traditional fan-cooling mode. They can reduce motor power and achieve energy efficiency in real sense.
• Permanent magnetic synchronous motor (PM motor) adopts high-performance NdFeB permanent magnet which will not lose magnetism under 200°C and its service life reaches as long as 15 years
• Stator coil uses dizzy-resistant enameled wire dedicated for frequency converter with outstanding insulating property and longer service life
• Coaxially integrated structural design, the motor has no bearing structure with high transmission efficiency
• Fill grease at regular intervals for free, and bearing replacement at regular intervals for free
• The motor has function of temperature protection (PTC/PT100)
• Oil cooled permanent magnet motors adopt sealed-up structure according to IP65 protection level. With waterproof and dust proof features, these motors hold lower requirements for environment. The motors well protected from dust and foreign matters present longer life span.

Permanent magnetic motor

• Reasonable structure and high power density
• Very small rotator inertia and very fast response speed
• Ultrahigh intrinsic coercive rare earth permanent magnetic material with strong anti demagnetizing capacity
• Possible constant torque output within scope of locked rotator and rated rotating speed
• Special asymmetrical magnetic circuit design, making low-rotating-speed torque ripple small
• High balancing precision, stable and high-speed operation, low noise and small vibration
• Full-sealed or high protection-grade appearance structural design

SKF-bearing

Compared with bearings of other brands, SKF bearing, it has good abrasive resistance, superior fatigue resistance, strong corrosion resistance and comfortable muting property, making longer service life, higher reliability and lower noise of permanent magnetic synchronous non-inductive motor.

Infinite volume control air inlet system

The compressor adopts infinite volume control air inlet system. It could operate without magnetic valve. Built-in function of the check valve can reduce malfunctions. The compressor is free from unloading process and shows higher energy efficiency. This compressor can operate at frequencies from 0-300HZ and realize high energy efficiency in real sense.

Industrial manager function

Wan Beardsley air compressor system can pre-set weekly work schedule according to your working hours in the factory, air compressor will punctually and automatically power on ana off accordinq to preset working schedule

Variable-frequency control range is broader with more energy conservation

It has advantages of low rotating speed high output torque, variable-freciuency control mode is broader than ordinary inductive variable-frequency motor, especially its 30%-80% air consumption in low-loaa working area saves by 15%-38% when compared with that of power-frequency compressor, and by 10% when compared with ordinary variable-frequency compressor. The lower load ratio, the more obvious the enerqv-savinq effect.

Leading constant pressure control

AVF permanent magnet variable frequency screw compressors can sustain the air supply at the pressure of 0.1 bar in any loading conditions. In case of larger demands for air supply, the compressor can increase its rotation speed without changing the pressure to guarantee the air volume. In case of lower demands for air supply, the compressor can reduce its rotation speed without changing the pressure to meet such demands. In case of no demands for air supply, the compressor will switch to sleep mode to save energy. When actual pressure achieves the wakening standard, the compressor will immediately start up with rapid response of frequency converters even in sleep mode.

High efficient centrifugal fan-cooling control system of double frequency (optional package)

• centrifugal fan-cooling permanent magnet motors adopt variable frequency control technology. They can save about 50% of the energy. Rotation speed of the cooling fan can be adjusted according to gas emission temperature, so as to reduce power consumption. Stable temperature of the overall system can improve durability of parts. In addition, variable frequency cooling fan can lower the noise.
• Centrifugal cooling fans are characterized by high efficiency, low noise, balanced pressure curve and other outstanding performances.

Reduce energy costs

• When the energy accounts for above 70% of the life cycle cost (LCC) of compressor, the energy consumption optimization becomes essential. In fact, the power consumption for the production of compressed air accounts for over 40% of the total power consumption of the plant, so the energy consumption optimization can even determine its success. Using the permanent-magnetism frequency-conversion technology of Dresdnerlan, we can provide partners for your cost saving. WZS series of products can truly reflect the demand for compressed air, making substantial energy saving become a reality
• Traditional compressors are operated between two set pressure points using the control methods of "full load and no load". The compressor turns into no load mode when the pressure reaches the maximum. When the air demand is medium or low, the no-load power will be consumed excessively, which will result in large amount of waste.
• Because no unnecessary power consumption will be generated, the energy cost reduced by the permanent-magnetism frequency-conversion can be up to 35% or more. The life cycle cost (LCC) of the compressor can be reduced by an average of 22%. In a word, compared with the compressor with invariable rotate speed, Wan Beardsley compressor can recover the extra cost within 1 or 2 years.

Steady Pressure

It tracks system gas volume changes automatically, and adjusts the revolving speed of compressor accurately with the use of PID (proportional, differential, integral), to keep the system pressure stable.

Start without stamping

• The variable frequency starting method reduces the impact of the start of the compressor on the power grid and mechanical parts greatly, thus extending the life of the machine.
• Eliminate invalid transitional period from full-load power to no-load power
• Avoid excessive no-load power consumption
• Maintain the net pressure section
• Reduce the overall average operating pressure
• System pressure is low, making the system leak declined to a minimum
• It accelerates with the use of soft-start motor gradually, to improve flexibility, thus avoiding the surge

Similarly, for two models with above rated power 37kw, when load rate is only 605, input power of power-frequency model under ordinary air inflow throttling control is 39.2kw_; while shaft power of permanent magnetic power-frequency motor is 23.6kw with electricity saving ratio being 37.5%. If we calculate according to 40,000 operating hours per year, annual electric charge of ordinary asynchronous power-frequency model is RMB 107,200, however, annual electric charge of permanent magnetic synchronous servo model is RMB 65,800, saving RMB 41,400 in each year.
