Spilling steam engine in an African sawmill.

Spilling is active globally – and so also as part of a project funded by the EU, for which Spilling delivered a steam engine to Africa. The engine was integrated into the existing steam and heat supply system of a sawmill and since then it satisfies the major part of the operational electricity supply. 

Beforehand, the company depended on the very unreliable public power supply or their own, expensive to operate emergency power diesel generator set – afterwards the supply was sustainably secured with inexpensive energy.
