Where it started — 2024
The eTRU began as a simple question on a workbench: could stored electrical energy run a refrigeration system reliably enough to stand in for a diesel transport refrigeration unit? In 2024 we set out to answer it — first with a bench prototype, then with the first unit on a trailer.
We started small and deliberately. A LiFePO₄ battery bank, an inverter, and a standard cooling unit were wired together on a bench so we could measure how the system behaved under real load — energy draw, run time, and stability — without committing to a full vehicle build.
This early rig is where the core architecture of the eTRU was validated: battery, power electronics, and refrigeration working together as one coherent electric standby system.
With the bench results in hand, the next step was a real, self-contained unit. The first eTRU trailer was built and fitted out in the workshop — taking the proven battery, inverter, and refrigeration architecture and packaging it into a mobile body that could be tested on the road.
It is the direct ancestor of every eTRU we deploy today: the same engineering-first approach, now scaled into complete systems with fleet telemetry and performance reporting.
