Our History

Olvondo Technology was established in 2016 as the two main owners, Olvondo Industries and LOS Gruppen acquired the assets and operation from former Single-Phase Power.
The company Single-Phase Power had over a period of ten years developed the Stirling based renewable energy technology known as SPP HighLift heatpump and SPP HeatPower engine. At the takeover the SPP technology was mature with more than 30.000 operational hours from commercial services.

The SPP technology are unique in its ability to provide high temperature lifts i.e., above 100oC, meaning it can recycle low temperature energy sources to high value process heat. Likewise the SPP technology may deliver steam up at temperatures up to 200oC. To our knowledge there are no other commercial available technologies that can provide similar uniqueness.


The customers for this technology are typically industrial players within food, aquaculture, chemical, and pharmaceutical industries as well as other industries with high steam consumption. Common for all are their interest in reducing emissions by making their energy green.
The two main owners are both partners of the industrial cluster at Bømlo on the West Coast of Norway sharing industrial traditions for decades.
Olvondo Industries was established 6th of December 2012 as a result of a so-called management buyout of the production facilities of the Wärtsilä gear and propeller factory at Rubbestadneset, Bømlo and continues a 110 year long production history in Rubbestadneset. The industry adventure started with the engine production from M. Haldorsen & Son Motorfabrikk in 1903 and which during the years grew to be the most significant engine factory in Norway.
LOS-Gruppen comprises LOS Elektro, LOS Marine and LOS Eiendom. The company was established in 1983 and is today the largest privately held electromechanical contractor on the Norwegian West Coast, providing services to maritime, offshore as well as land based industries. In 2014 LOS-Gruppen acquired the marine service unit of Wärtsilä at Rubbestadneset, now a fully integrated part of the LOS Marine operation.


Both Olvondo Industries and LOS-Gruppen are actively pursuing opportunities within renewable energy as part of their strategies. They both share a common interest in becoming manufacturers of Green Shift technology. With their severe competence and industrial heritage Olvondo Industries and LOS-Gruppen the manufacturing of Olvondo Technology’s product portfolio is in the best possible hands.
