Intelligent dry screw vacuum pump with VSD technology DWS 450-750 VSD+

The DWS VSD+ series of dry screw vacuum pumps, equipped with ElektronikonTM are designed for harsh industrial applications and offer lower lifecycle costs, higher productivity, less energy consumption, and low maintenance.

DWS 450-750 VSD+ – Intelligent dry screw vacuum pump with an IP rated canopy and remote monitoring features

The new Atlas Copco DWS VSD⁺ dry screw vacuum pump is a plug and play industrial vacuum pump. Intelligently engineered for long-life operations and designed for harsh applications, the DWS VSD⁺ dry screw vacuum pump series offers improved operational performance and stable vacuum. Screw vacuum technology is an ideal solution for many applications in packaging, drying, electronics, plasma processes, LED manufacturing, and solar.

The vacuum pump is friendly on the environment – the dry screw operations of the DWS VSD⁺ mean there is no contaminated or dirty oil to dispose of lowering recurring maintenance costs significantly.

In addition to lower maintenance costs, you can expect significantly lower energy and utility costs.

The Variable Speed Drive (VSD) technology built-in to the pump optimizes energy consumption leading to substantial energy savings. The robust and compact canopy offers your installation an economical footprint, saving you space on your production floor or in your vacuum utility room.
