Atlas Copco has launched three new intelligent VSD+ vacuum pumps in the U.S. market. The DZS 100 to 400 VSD+ series pumps are a range of air-cooled, oil-free claw pumps made for particularly harsh applications. They come with built-in variable speed drive (VSD) and can be controlled remotely by the new VSD+ App.

To better prepare the equipment for harsh application environments, Atlas Copco has also equipped its DZS 100, 200 and 400 VSD+ series with corrosion-resistant materials and a durable internal coating, while also reducing the environmental impact thanks to its low energy consumption, small space requirements, as well as handling of pollutants. The DZS pump range is perfect for conveying, clamping and drying processes.

No new synchronization is necessary during the subsequent assembly, resulting in shortened downtimes and lower service costs.

To control the pumps, a VSD+ inverter drive has been integrated into the motors. This allows for the optimum performance points of the claw pump to be specifically controlled and for power consumption to be reduced. This function ensures that energy is saved and that the pumps’ carbon dioxide footprint is reduced. Sustainability is further reinforced in the immediate process environment: Certified to ISO 8573-1 Class 0 standards, the completely oil-free DZS VSD+ pumps are 100% harmless to ambient air quality during operation. This eliminates the risk of oil-induced contamination and damage to sensitive applications and products in the environment, providing a guarantee that neither man nor the environment will be harmed by the use of the pumps.


New integrated app

The new DZS range, along with the current GVS A VSD+ range, are the first models to benefit from the advanced technology of the newly developed VSD+ App. The new app allows the vacuum pumps to be controlled and monitored in real time from a smartphone. Pumps can also be commissioned optionally by entering fewer set points. With just a few clicks, the performance of the pump can be precisely adjusted to the respective process requirements, this added functionality helps ensure greater user-friendliness and noticeably more energy-efficient operation.

In addition, users have quick access to numerous operation parameters, including values such as inlet pressure, rotor speed, running hours and service intervals can be monitored and controlled at a glance in real time. The new app also makes it easy to commission the connected pumps through the target pressure, start/stop delay and stop level parameters. When the pump is started, the app automatically connects via Bluetooth. Once the desired values have been entered, the innovative DZS 100 to 400 VSD+ series starts operation immediately.

The Atlas Copco VSD+ can be downloaded from relevant app stores. Minimum requirements are IOS 8.0 and Android 4.03. Atlas Copco plans to make the app available for other vacuum pump models in the future.
