Phase 2 trial to start with global online retailer

Tan Delta (AIM:TAND), a leading provider of intelligent real time sensor-based monitoring and maintenance systems for commercial and industrial equipment, is pleased to announce the commencement of a paid for Phase 2 trial by one of the world's largest multi-national online retailers (the "Customer") to evaluate Tan Delta's real time oil condition analysis and monitoring systems.

The Customer is seeking to monitor critical gearboxes used on conveyor systems inside their distribution centres in order to prevent unplanned downtime and optimise maintenance practices based upon need rather than fixed time schedules. 

Phase 1 saw the installation and operation of sensor systems on five of their gearboxes in one distribution hub and proved the capability of the Tan Delta solution to detect and track changes in oil and gearbox condition. Phase 2, will see this expanded to more gearboxes in multiple distribution centres, both in Europe and USA along with some data analytic integration. The first purchase order for Phase 2 was received in this month and the actual trial is expected to commence early in the 2026.  

Chris Greenwood, Tan Delta CEO said:

"This customer has tens of thousands of critical gearboxes across its distribution estate, all of which rely upon oil for lubrication and reliable operation. Continuous monitoring will enable them to plan and co-ordinate maintenance to minimise distribution centre disruption. Phase 1 proved to them that our sensor system does what it says and Phase 2 is seeking to validate this further as well as targeting the evaluation of the practicalities of a wider deployment and integration into their existing maintenance systems which are already very significant. Whilst the timing of this opportunity progressing into a wider rollout is currently unknown it is progressing steadily, is another very significant future opportunity for us and it is notable that the customer is paying us for the Phase 2 trial."
