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.

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-performance vector frequency converter

reduces magnetic field interference outside high-frequency machine
generated by frequency converter;

starting;

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.
Energy Saving
- Traditional compressors (standard machine) usually use ON / OFF or
proportional regulation system, which adjusts the opening amount of
the air inlet of compressor. The adjustment method can also meet
the actual requirements of the actual gas consumption, but the
revolving speed of the compressor maintains at the rated speed in
the entire adjustment process, the frictional work and cooling
fluid agitation work will not be reduced, so although the gas
consumption is lowered, the actual power consumption is not limited
substantially. The variable frequency regulation can make the
actual power consumption of the variable frequency compressor
decline in the same proportion, and the energy is effectively used
into the air compression.
- In the market environment with fierce competition, it is an
important matter as to whether the cost can be reduced. With the
use of PM frequency conversion technology, you can save energy,
thereby decreasing electricity expenditure sharply. It adjusts the
compressor production capacity automatically according
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.
Difference of servo permanent magnetic variable-frequency
technology and non-variable frequency technology in energy
conservation
Non variable-frequency unit regulates demand for air discharqe with
modulatinq capacity valve, while servo permanent magnetic
variable-frequency unit regulates demand for air discharge in way
of motor frequency conversion, and comparison of energy
conservation between the two is as following:
