HT-HC Hydraulic Pressure Cycling System — High Pressure with Thermal Chamber
Pressure cycling and temperature cycling in one bench: 1 – 40 MPa hydraulic pulses inside a −70 to +180 °C chamber, run from a single program.
The HT-HC puts the pressure source and the temperature chamber in one cabinet. Pressure pulses and chamber temperature are programmed together and run on the same time base, so a part can be cycled hot, cold, and through a ramp while the pressure profile continues — the combination that most automotive validation profiles actually demand.

What it does
- Runs the pressure profile and the temperature profile from one program, on one clock.
- Holds the part at temperature while pressure continues to cycle, instead of testing the two separately.
- Records pressure and time across the whole run, so the sequence can be shown in a validation report.
- Keeps the hydraulic circuit outside the chamber, with only the pressure line entering it.
Typical use
- Automotive component validation where the specification combines pressure cycling with thermal exposure.
- Pressure sensors and transmitters qualified over their operating temperature range.
- Seal, hose and joint testing where cold makes the difference between passing and failing.
- Design-limit investigation: raising temperature and pressure together until the part gives.
How a unit is specified
Part count, cavity volume, frequency, and the temperature range and ramp rate. The chamber volume has to be chosen with the fixture in it — a fixture that fills the chamber removes the air movement the chamber needs to change temperature quickly.
Standard and custom
The hydraulic power unit and the chamber are the standard platform. The fixture station inside the chamber, its feed-through, and the port arrangement are built to the part.
