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 applications The DWS VSD⁺ series features a rugged design for extended uptime.longer maintenance intervals,low maintenance costs.
3.Low running costs Variable 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 friendly The 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.
