Atlas Copco’s GHS VSD+ vacuum pump range offer Industry 4.0 functionalities

Atlas Copco’s (Stockholm, Sweden) GHS 1402-2002 VSD+ variable speed-driven, oil-injected screw vacuum pumps series offer intelligent networking of vacuum pump and process. In addition to optimal oil separation, the GHS VSD+ range is also well suited for the composites industry, especially for vacuum bagging and hold/clamping. Used for central vacuum installations rather than a point-of-use machine, the series of pumps are said to feature a new “forward-looking” design for better performance, a smaller footprint and HEX@TM, a new controller to enhance Industry 4.0 capabilities.

The new model is offered in three pumping speed classes. In rough vacuum applications, the oil-injected pumps deliver a continuously high pumping speed — from atmospheric pressure to ultimate pressure — proving them ideal for use in central vacuum systems, for vacuum cooling, the production of food packaging and thermoformed plastic components, as well as for vacuum chambers for altitude simulation. 

Compared to previous models, the GHS 1402, GHS 1602 and GHS 2002 VSD+ are reported to result in better vacuum performance, a 15% smaller footprint— the GHS 1402-2002 VSD+ is smaller than 2 m², due to the vertical drivetrain design — and longer maintenance intervals. 

The GHS VSD+ screw pump also contributes significantly to saving energy costs, Atlas Copco notes. This is based on the combination of the Neos inverter with a setpoint control. This means that the GHS 1402-2002 VSD+ deliver the exact pumping speed required for the respective process. Moreover, an energy recovery system helps recover up to 80% of the power in the form of hot water, which also results in lower CO₂ emissions.

A permanent magnet motor also contributes to increased efficiency. In its IE5 efficiency class, the company says the pump produces an increase in efficiency of about 2% over the entire speed range. Oil cooling maintains the optimal motor temperature at all speeds. The motor bearings are also lubricated by oil, which eliminates the need for regular relubrication. The motor is enclosed in a housing with IP66 protection, increasing its resistance to rough and dusty application environments. 

Integration of an intelligent functionality, the HEX@TM controller, ensures high vacuum performance and user friendliness, Atlas Copco adds. HEX@ has a configurable user interface that can be tailored to a user’s own needs and priorities. Via the controller, users can visualize and set the parameters of the pumps from any smartphone, laptop, PC or tablet via a web browser, regardless of location. Other smart functionalities vary from intelligent scheduling over pump down optimization to leak detection.
