Engineering & Systems
Need system-level work or diagnostics?
Beyond single units, we take on system-level work on site and at our shop: diagnostics, wiring, controls, refrigeration and assembly.
The SD in HSD stands for System Design.
Work like this
- A system fault that still needs tracing.
- Valve control relay modules and logic.
- Components that no longer communicate with each other.
- Wiring, repaired or redone.
- Vacuum plumbing and mechanical assembly.
- A system or cabinet to assemble to an existing design.
HSD Vacuum Furnace

We designed and built this furnace for vacuum brazing and degassing. It runs on a PLC, and PLC controls are part of the system work we take on.
If your system is missing a part, ask us to supply it. We will see what we can do.
Other work we do
We also repair and rebuild, calibrate and service lab equipment.
Tell us about your system
Email info@hsdengineering.com or call (510) 553-9132. Tell us who made it, the model and what it does wrong, and we will quote it.
For assembly work, tell us what needs putting together. We work out the scope with you on the call or by email.
