The Portuguese-based panel manufacturing group said an agreement had been signed with an as yet unnamed party for the purchase of the equipment at Knowsley.
It is not yet clear where the equipment will be headed, although speculation has centred on eastern Europe and China.
The closure of the Knowlsey plant was announced in September following consultation with employees and trade union representatives.
Sonae said the decision was the result of long delays to reconstruct parts of the factory due to a serious fire the previous summer. It blamed political and licensing difficulties, as well as the reduced and unsustainable capacity levels for the decision. However, Sonae is still hoping to supply the UK market from its other European plants.
