Ecotherm: solar steam generation

Cluster-News: July 2018

Ecotherm offers a complete solar steam generation system for industry that permits a reduction of up to 30 % of the oil and gas consumption of existing steam boilers. Moving mirrors concentrate the incoming solar radiation on to the receiver. Motors allow the mirrors to track the movement of the sun. The water in the receiver vaporises. Steam of up to 250 °C can be generated and integrated into existing steam systems. In addition, Ecotherm also offers a new high-performance flat-plate heat exchanger with high peak capacity and a large heat exchange surface.
