Vacuum Gauge & Controller Selection Guide

To help customers quickly identify the best VACUUBRAND gauge or controller for their needs, we’ve created a new selection guide.  Answer 4 simple questions and you’ll get a product recommendation to meet your specs.  You can request a quote directly through the selection guide.  Or if you’d like to talk with us to discuss your ...


VAC 24seven - dry, chemical resistant process vacuum

VACUUBRAND’s modular VAC 24seven pumping systems provide a dry, chemical resistant vacuum source for industrial and process applications. Watch the video below or visit www.vacuubrand-process.com to learn more. ...


Local Vacuum Networks - the Reliable Alternative to Central Systems

In addition to VACUUBRAND’s pumps, gauges, and controls, our VACUU·LAN® local vacuum networks are a lab-by-lab alternative to central vacuum systems.  VACUU·LAN networks provide deep, stable vacuum in new labs and in renovation projects.  Built on VACUUBRAND’s durable, chemical-resistant diaphragm pump technology, these local vacuum networks offer a reliable, low-maintenance solution for vacuum in research ...


Respirable Crystalline Silica - Nol-Tec Offers Compliance Solution

Early in 2016, OSHA (the Occupational Health and Safety Administration) announced its “final rule” regarding respirable crystalline silica. This rule has been under consideration since 2013. The final ruling reduces the permissible exposure limit (or PEL) for workers in businesses where workers are frequently exposed to respirable crystalline silica. A Decades-Late Update Crystalline silica is a common ...


Fine Vacuum Control

Many important research and industrial processes require vacuum in what is referred to as the ”fine vacuum” range, which is between 0.1 and 0.001 Torr. In a prior post, we talked about the fact that the Pirani style gauge is often the best option in the fine vacuum range. VACUUBRAND offers fine vacuum control packages in ...


Vacuum Pump Sizing - Evacuating a Chamber

We’ve previously talked about some of the tools we’ve made available to help select the right vacuum pump for your work.  Our pump selection guide is a great choice if you have a strong sense of your operating parameters.  And for drying processes, we’ve put together tools that help estimate the process time or pumping speed (flow ...


Advanced Vacuum Control

Our most recent post addressed the benefits of proportional-only vacuum process control.  Though this approach is well suited to many processes, in some cases more accurate (or precise) control of the pressure level is necessary.  Under such circumstances, employing a PI (proportional-integral), PD (proportional-derivative), or full PID (proportional-integral-derivative) control algorithms are appropriate solutions. If a P-only ...


NEW YEAR + NEW LOCATION = STREAMLINED OPERATIONS

We are officially settled into our new headquarters building located at 2009 Renaissance Boulevard, King of Prussia, PA. We briefly touched on the move in our end of year blog posted Dec. 30th and are excited to report that the move went smoothly… We haven’t missed a beat! 2009 Renaissance Blvd., King of Prussia PA — ...


Proportional (2 Point) Vacuum Control

In our prior post, we talked about using variants of classic PID algorithm in order to control vacuum processes.  In the simplest form, the PID control loop can be reduced to a P-only, or 2-point, algorithm.  For example, by using a PLC or other control module to read an accurate vacuum sensor and actuate an ...


Approaches to Vacuum Control

Establishing good control over vacuum processes has numerous benefits, such as helping to improve process yields, achieve more repeatable results, and reduce process times.  And there are several options for controlling vacuum processes to achieve these various benefits.  This post will briefly review some of the more common approaches to vacuum control.  Subsequent posts will ...
