Waste heat to electricity solutions

Visorc Oy is a manufacturer for waste heat recovery solutions. Visorc’s almost maintenance free energy converter generates electricity from flue gases of diesel and gas engines and gas turbines with high conversion efficiency.

Visorc Oy 

Visorc Oy is technology development oriented company founded in 2014 for commercializing the Micro-ORC energy converter technology and introducing the technology in the markets.

The core group of Visorc Oy consist of the high-speed and ORC-technology professionals having a background in Lappeenranta University of Technology, FInland. The company is targeting to strong growht and global markets. 





Visorc’s from waste heat to electricity solutions are capable of efficiently converting waste heat into electricity. The technology is based on intensive research and product development for recognizing optimal solutions for heat recovery.

The company has established wide product development network and the company owns comprehensive IP rights over the technology. Our technology can provide significant fuel savings, reductions of CO2 emissions, and has a short payback time in various applications.

Visorc waste heat recovery solutions are based on the use of an organic fluid which enables to efficiently recover different types of waste heat streams.The electrical power range output range of Visorc’s commercial energy converters is 10 kW - 50 kW. 

The Visorc’s core technology is based on the use of high-speed turbogenerators which enables to achieve many benefits when compared to other waste heat recovery technologies:
