Technológia Engineering Ltd produces heat economizers from finned iron-cast-tubes, finned stainless
steel tubes and finned carbon steel tubes with dip galvanization.
The tubes are convenient for recovering heat from high temperature corrosive and erosive smoke and
exhaust gas. They also can be applicable on a temperature beyond dew point, for exhaust gas of
destructor or refuse burner.
Ribbed casting tube is quadrangular and is made of parts of a length of 200 and 250 mm. After surface
finishing the parts are beaded on a core tube, then the core tube undergo a 1000 bar inside hydraulic
pressure load. The consequence is a cold creep which ensures a metal-through connection between core
tube and cast iron.
The heat economizer made of that kind of tubes has a large outside surface because of the great number
of ribs and that is the reason for good thermal and laminar conditions. They have little space demand and
life expectance is very high.
Our company designs and produces heat economizers and converts ECO's made from naked tubes. Efficient
and long life heat economizers are an important device for improving efficiency of boilers.
