Tan Delta Systems PLC (AIM:TAND) shares soared 40% to 35p on Thursday after the sensor technology firm announced the start of a paid second-phase trial with one of the world’s largest online retailers.
The customer, which operates a vast network of automated distribution centres, is testing Tan Delta’s oil condition monitoring technology to help prevent gearbox failures and reduce costly downtime.
Following a successful first phase, which monitored five gearboxes at a single site, the new trial will expand to multiple distribution centres across Europe and the US.
It will also integrate Tan Delta’s real-time data analytics into the customer’s maintenance systems. The company has already received an initial purchase order, with the trial expected to begin early in 2026.
Chief executive Chris Greenwood said the customer’s estate includes “tens of thousands” of gearboxes that could benefit from continuous monitoring.
“Phase 2 seeks to validate practical deployment and integration into their existing systems,” he said, adding that the paid nature of the trial marked a significant step forward.
Although there is no timeline for a full rollout, investors welcomed the development as a potential gateway to a major global contract, underlining Tan Delta’s growing traction in industrial predictive maintenance technology.
