energy-saving oil free screw air compressor for food processing
I. Technique Introduction:
The oil-free screw compressor adopts European water- lubricating
air end. Being resistant to corrosion, it’s free of deformation in
high and low temperature environments. A separate lubricating
watercourse is adopted inside to minimize abrasion of the air end,
reduce air pollution and increase the air flowing speed. It adopts
original water separation and softening systems imported from
Germany to increase the water separation effect and make sure the
water content in the exhaust air less than 2mg/m3.
It adopts the copper screw and imported DOS. DS sealing materials
so that the sealing and engagement of the screw are tighter and the
sealing materials are more wear-resisting.
It adopts imported SKF bearing , plus the separate internal
hermetic seal technology to guarantee absolutely zero contact
between lubricating water and bearings, reduce rustiness of
bearings caused by lubricating water and make sure of the service
life of bearings exceeding 50000 hours.
Its water system adopts the unique water filtration and lubrication
system of German DOS. DS to make the best use of lubrication,
sealing noise reduction and cooling functions. The full automatic
water control system ensures the reasonable water flow and reduces
the compressor’s power loss.
It adopts a design of double systems: air and water cooling to
ensure the easy use and installation for customers.
All adopt the direct connection transmission with the lowest power
It adopts water as the medium of cooling, compression and sealing
to make the cost lowest.

1.Enormous potentiality, long history
Shanghai Honest Compressor Co., Ltd. is one British wholly-owned
enterprise. Currently in China, OSG has set up three major
manufacturing bases (Shanghai Honest Compressor Co., Ltd, Zhejiang
Ulite Tools Co.,Ltd., Guangdong OSG welding), five Manufacturers.
Meanwhile we cooperate with the European world-advance air end
manufacturer. OSG shanghai possesses a complete production, sales
and after-sales service system. OSG has 40 offices and more than 80
after-sales service centers, and products are sold to more than 20
2. Advanced configuration, world-renowned components, abundant
The control system is the most advanced. The controller is designed
and manufactured by Schneider, France. It is equipped with the
large Chinese-English liquid crystal display screen. It can monitor
more than 20 main operating parameters, and has the functions of
fault recording, maintenance and alarm shutdown. It can achieve
efficient intelligent control, unattended.
Remote control: the computer processor can directly check the
user's real-time operating system. Combine the reliability, energy
saving, practicality in one. remote control can start, stop, load,
unload the compressor and also other local control can be carried
out. The operation, alarm and fault and relative local information
can be monitored. (detailed description followed)
Remote control function:
Multiple compressors remote centralized control: reduce system
pressure, reduce energy consumption, real-time monitoring.
Dual pressure setting: Two system pressure bands can be set
manually or automatically to optimize energy use and reduce
Delayed secondary shutdown: This function controls the motor to run
only when needed, allowing the motor to run less and minimize the
