Key benefits

1
Stable Energy Costs
Solar thermal boiler represents a significant cost reduction in any industrial scale production. In comparison to fossil-fuel based boilers, manufacturers are saving up to 75% in their boiler systems.
2
Energy Security
Solar hot water boiler provides uninterrupted and always- dispatchable energy at an affordable cost. Solar thermal boilers mean that industrial customers are no longer dependant on fossil fuels.
3
Sustainable Technology
Solar energy is green and produces zero CO2 emissions. Our technologies help our customers to become climate neutral, helping to put a value on their negative CO2 emissions through the internal carbon tax mechanism.

In 2020, we added Protarget’s vacuum tube collectors along with the thermal energy storage to our fruit juice production plant in Cyprus. The CPC collectors have been mounted on the roof of our factory and the system operates fully automatically, harvesting Cyprus’s plentiful solar resources. Not only do we have a constant 24/7 dispatchable hot water, most notably, we have saved significant amount in fossil fuel consumption and reduced our CO2 emissions.
