Custom Request

As engineers continue to push the boundaries of what can be done, we’re in step right beside them, building the process equipment our customers need to remain at the forefront of innovation.

Our new product development is typically driven by custom requests, so we encourage you to contact us online or by calling 1-888-937-3637 (US toll free) or 1-925-373-8353 (worldwide).

Our goal is to provide our customers with improved processes, not just tools. We have a complete staff of process, design, mechanical, electrical, software and service engineers ready to assist with your process needs. All our work is done in house—we do not outsource. This keeps our resources close at hand when you need us.

For over 30 years, listening to our customers has driven our new product development. Responding to the needs of innovative process engineers is more than our business model--it's our passion.

We look forward to speaking with you.
