Low Noise Screw Air Compressor With Touch Screen PLC Controller
64dB(A)
Screw Air Compressor Advantage
1) 100% OIL-FREE :
TUV Class 0 Oil-free Certificate
Clean air:purified by water,without dust
2) At Least 30% Energy-saving :
Single screw air compressor theoretically doesn’t have any
clearance volume
The water used as a lubricating medium also seals gap inside the
compression chamber,and enables high efficient operation at low
speeds(about 3000r/min)
Using water as a cooling method keep compressor Ideal isothermal
compressio
Variable frequency inverter
Two-stage compression medium pressure screw air compressor:domestic
initiative patent product(application number:ZL 2016 2 0206277.4)
3) Environment protection :
No discharge of three wastes; Low vibration and less noise
Screw Air Compressor Features
SEPARATED COOLING SYSTEM
The centrifugal fan is activated automatically by the thermostatic
control through the controller. This allows the machine to quickly
reach
and precisely maintain the ideal operating temperature.
THERMOSTATIC VALVE
The thermostatic valve regulates the oil temperature, preventing
the formation
of condensate inside the oil-separator vessel.
EASE Of ACCESS TO ALL COMPONENTS
All main components can be readily accessed from the large front
access door. This allows convenient inspection with fast
and simple maintenance.
COMPACT, SPACE SAVING DESIGN
The compact design is ideal for installation when space is
restricted or in situations when the compressor needs to be
installed near the production activity.
BELT-DRIVEN TRANSMISSION
The POLY-V belt-drive ensures significantly lower power losses and
three times the service life compared to standard range “V” type
belts fitted to other compressors on the market.
Belt tensioning is carried out through a slider system.
LOW NOISE LEVEL
The centrifugal fan design along with the careful arrangement of
all other components within the machine added to extensive sound
insulation results in the LGSD, offering very low operating noise
levels.
ELECTRONIC CONTROLLER
(installed on models from 4 to 22 kW)
The complete functioning of the compressor is precisely monitored
by the advanced controller. This highly developed system allows the
machine’s operation to be fully programmed in several languages and
also allows remote control, access to the maintenance schedule,
etc.
The backlight display shows: working pressure, working/load hours,
load/idle running, oil temperature.
The controller stores a fault log for easier troubleshooting.
Start/stop and safety operation controls are easily accessible. It
includes a phase sequence relay to check motor direction of
rotation.
