12High-efficiency
Scroll
The special low-pressure loss and large flow area design,
compared with traditional centrifugal compressors:
• The volute runner of the traditional compressor is square or
semicircle design. The airflow turns more than 90 degrees
when the high-speed airflow impacts, and the enormous
aerodynamic loss
• UCS compressor's volute airflow passage section is a circular
design, airflow spiral flow without rapid turn, less pressure
loss, three compression stage total energy-saving can
improve 1%-2%

90% maintenance time saved;
• No consumption parts and low maintenance cost;
• Larger design, high heat exchange efficiency, low water
consumption and low-pressure loss, about 1-2% energy
saving;
• Variable cross-section design, perfect air-liquid separation
effect;
• Stainless steel backing core design, eliminating corrosion
risk;
• No fastening parts, no risk of damaging the impellor by
fallen pieces;
• Supported by both side, eliminating the damage risk from
resonance;
• Long life span drainer, no rusty, enormous draining and zero
air consumption.
• Standard equipped with two intercoolers;
• The final exhaust temperature in winter greater than 120℃;
• Perfect match with zero air consumption compression-heat
regeneration dryer (no electric heating required)
14Patented Compact
Design For
Air & Oil Cooler
• Compact structure short passes, save installation space, easy
installation;
• Constant pressure water supply for oil and air cooling
reduces the risk of water contend.
15Smart Energy-saving
Control Mode
The Advantages Of IGV Over The Butterfly Valve
• Compressors with IGVs are 7-9% more efficient than those
with butterfly valves because the IGV has a pre-spin effect on
the intake so that the air enters the impeller at the same
Angle as the impeller. The IGV can also provide a broader
regulation range, allowing minor airflow disturbance and
smooth regulation.
0-100% Flow Adjustment Instructions IGV
• The compressor's working flow range can be 0-100% by high-
reliability BOCV, which can load/unload 200000 times per
year.
16The Advanced Local
Control System
SIEMENS PLC
• The advanced Siemens PLC system +7” touch screen, user-
friendly interface and easy operation;
• Options for auto dual, constant pressure control and self-
balance control mode;
• All operating parameters can be displayed and set;
• Features for various alarm and trip conditions;
• Features anti-surge and surge prediction functions;
• Communication to DCS by DH+, Modbus, Profibus or
Ethernet.
