Atlas Copco's tradition of driving industrial innovation has
allowed us to design the DWS VSD⁺ dry screw pump, an important
addition to our innovative range of industrial dry pumps.The DWS
VSD⁺ dry screw pump is an important addition to our range of
innovative industrial dry pumps.
The DWS VSD⁺ range features a smart, simple design that is durable
and delivers performance, utilising the concept of the concept of
simple control and reduce maintenance costs.
1.Higher operating performance and stable vacuum level
Increased productivity and shorter evacuation times due to higher
roughing speeds and lower ultimate pressures down to <10⁻².
2.Rugged design for harsh industrial applicationsThe DWS VSD⁺ series features a rugged design for extended
uptime.longer maintenance intervals,low maintenance costs.
3.Low running costsVariable Speed Drive (VSD) technology optimises energy consumption,
resulting in significant energy savings. In addition, the compact
design reduces the amount of space occupied in the production hall
or machine room.
4.Environmentally friendlyThe dry screw technology of the DWS VSD⁺ means that there are no
emissions of oily oil mist. It has a minimal impact on the
environment and reduces recurring maintenance costs.
Innovation from the heart, intelligence from the mind
Screw vacuum technology is the ideal solution for many applications
such as packaging, drying, electronics, plasma processes, LED
manufacturing and solar energy, to name just a few applications. It is clean, efficient and
offers a great deal of convenience.
1.Pre-wired and systemised
- Rugged, compact enclosure meets IP54 requirements
- Electrical connections connected, wired and assembled
- Plug and play, easy to install
2.Robust construction and cleverly designed components- Reliable constant flow cooling system
- Reliable new purge system including manual gas ballast
- Non-contact, long-life seals for efficient sealing
3.Intelligent Technology
- With Elektronikon® for advanced remote monitoring of the pump,
e.g. status, run/shutdown times,programmable timers and setpoint
control, etc.
- Gearbox and vacuum chamber are isolated from contamination and
remain oil-free from overflow
- State-of-the-art high quality bearings and low volatile
speciality lubricants
- The non-cantilevered design provides excellent rotor support,
ensuring fast start-up and low vibration.
- Pneumatic air inlet valves are included as standard equipment.
The air inlet valve is operated by the Mk5 computerised
controller.Automatic warm-up and shutdown purge cycles are
possible, with automatic isolation from the vacuum network.
