Industries are wasting heat in form of flue gases such as from various Industrial furnaces, turbines and
reciprocating electric generators, we can use waste flue gases and convert into hot water or hot thermic oil by waste heat recovery boilers.


Hot water can be use for any industrial or commercial application, such as:
-Hot water fired absorption air conditioning
- Textile dying and washing
- Boiler feeding
- Central heating
- Combustion air and fuel pre heating
- Drying
- Hotel’s kitchens, laundries and as domestic use


Boilers designs for individual client’s requirements, heat recovery boilers can be horizontal or vertical, fire tube or water tube and single or two pass.


Boilers are designed for easy maintenance and repair as per ASME codes.
Refractory lined where required and 80 to 160 Kg Rock wool jacketed with M.S. Color Sheet or S.S.
sheet where required.
