ZFR is a shell boiler that consists of a three-pass provision along with two independent flame tubes and smoke gas passages with a dependable steam and heat resource in the increased output range.

This dual flame/smoke boiler is ideal for one burner operations along with three- pass provision attached with a backward chamber that was patented in 1952. The economizer and super-heater can be attached using the angular base while the direction of flame and smoke tubes along with water and steam chambers are enhanced with regards to thermodynamics.

Use of one flame tube can lead to a bright and convection heating base by transforming the heat into steam and making sure the materials are intact due to the fittings inserted on the water side.
