Detailed Product Description
Name: Two Stage Screw Air Compressor Power: 55kw
Pressure: 8bar Air Flow: 12.3m3/min

Advantages of two-stage screw air compressors:

∎This latest generation of energy efficient air compressors
can SAVE 15 – 20% on your power bills.Our ground-breaking range
of DD Series ‘2 Stage’ rotary screw air compressors offer outstanding
energy savings when compared to conventional single-stage compressors.
∎Our extensive range covers capacities from 15.8m³/min@6bar (55kW) up to
65m³/min@8bar (315kW) and with pressures ranging up to 13 barg.
∎This is by far the widest range of two-stage rotary screw air
compressors available!

 

How two-stage screw air compressor saveing energy:

Sample compressor 250kw 2-stage:
∎Air capacity: 250kw single stage compressor 40m3/min @8bar;
while 250kw two-stage compressor 50m3/min @8bar.
∎Power consumption: single stage compressor 250kw + 75kw can make
50m3/min @8bar, so that 250kw two-stage compressor can save power 75kw,
and one compressor can work for many years,75kw will save quite a lot.
∎Electric motor and inverter, 250kw two-stage compressor, with permanent
magnet motor, it's high frequency 150hz, it work quite good when compressor
not work at full load, and normally compressors will not work at full load all the
time, this way, permanent magnent motor will make no extra consumption as
fixed speed motors.
Price, 250kw two-stage PM & VSD compressor,
it's price is less than 250kw+75kw single stage
VSD compressors, while make 50m3/min @8bar.
