The AIM-traded firm said the equipment, based on its induction heating technology, was originally provided following a contract announced in March 2014.

It said the contract followed an initial £50,000 design and scoping phase carried out in recent months.

The majority of the revenue from the upgrade was expected to be recognised in 2025, with the deal not affecting the board's financial expectations for that year.
