¡á The Senter for exhaust gas! An answer to the best waste heat recovering equipment

 

Having spearheaded the development of waste heat recovering equipments, Hitecec has succeeded in putting to the practical use of the Senter, the best waste heat recovering system using exhaust gases. The development success became only attained through the multi-year efforts based on Hitecec's the accumulated high technologies in the past. With the Senter equipment, we are ready to serve your energy saving efforts.

 

<Principle and design concept>

 

¢ÀAll the exhaust air and feed air that are emitted from the drying machines or similar equipments, is designed to flow through the elements completely, achieving the best heat exchanges.
¢À With the adoption of corrosion-resistant and heat-resistant special materials, it enables you to maximize the heat transfer areas with the least volume available. The elements are designed optimized relative to the exhaust air quality and temperature.
¢À The introduction of the latest technology in consideration of the special design requirements of the high-temperature heat exchangers.

<Characteristics>
¢À Able to install in the existing facilities without giving the business interruptions.
¢À Commercializing elements in the appropriate manner and perfect design according to the installation place and its usages.
¢À Superior economics
¢À No noise, vibration and dangers.

< Applications>
¢À The exhaust heat recovered from thermal treating facilities and drying machines are reused directly as feed air.
¢À The high-temperature exhaust air heat recovered from the thermal medium boilers and other similar equipments is used for drying machines or heating purposes.
¢À The exhaust steam heat is recovered and used for heating feed water.
¢À The high-temperature exhaust air heat is recovered from the heating machines, and used for bathtub water supply.
