Through multiple patented innovations, our PowerFlex family of boilers offers energy efficiency above the competition, and allows our customers to save on operating costs while reducing flue gas emissions and meeting present and future limits on exhaust emissions. Starting from a proven design with many thousands of units currently in operation, our engineers have made numerous improvements using modern tools such as design 3D modelling and computational fluid dynamics (CFD).

Every boiler is covered by a comprehensive warranty and full technical support is provided 24/7 through our network of service companies.

Our modern, innovative equipment is designed and manufactured to the highest quality standards while remaining competitively priced to respond to the new economic and environmental realities facing our clients.

The Novatherm's firetube boiler eVoTube is the next generation of this well-known firetube design. It contains several improvements such as over-sized furnace located as close as possible to the centre of the tubesheet.  The firetubes are located concentrically about the furnace creating a gradual temperature gradient across the surface of the tubesheet.  

A patented integral steaming economiser can also be added to increase the efficiency of the firetube boiler.

The eVoTube firetube boiler is offered in multiple configurations.  It comes with a semi-wet back or a complete wet back in 2, 3 or 4 gas passes and the package can be supplied with the latest burner technology to achieve the most restricting emissions and the best performances.
