Concentric air / flue stainless steel chimney

Intended use:

This system is designed to discharge smoke from gas and oil devices with a hermetic combustion chamber, where the discharge of fumes is a result of pressure generated by the fans in the boiler.

The system is constructed of two coaxial pipes, where the internal pipe is used for smoke discharge and the external pipe for oxygen inflow to the combustion chamber. All elements are plasma-welded with a longitudinal seam weld, the ends of the elements’ are equipped with seals ensuring that system is hermetically sealed.
