Welcome to Kentube Engineered Products
Kentube Engineered Products specializes in designing and manufacturing economizers (for packaged and waste heat boilers), tubular air heaters, and other high-temperature heat-recovery applications. Applications range from small 40 HP boilers to large field-assembled units (shipped as modules). Kentube has been setting design standards for this industry for more than 40 years.

Reduce fuel, reduce costs, and achieve fast payback
Reduce fuel and fuel costs. Economizers are fabricated assemblies of finned tubing that recycle heat produced by your boiler. They remove heat from the flue gases and return it to the boiler feedwater so less fuel is required by the boiler to generate a given amount of steam.

  • Indoor or outdoor installation
  • Orientations may be vertical or horizontal
  • Versatility equals lower installation costs
Decrease Thermal Pollution
By removing heat from the boiler's flue gases, an economizer lowers the temperature of these gases before they exit into the atmosphere.

Guaranteed Thermal Performance
All Kentube economizers are backed by a performance guarantee. Each individual unit is computer designed to match exactly the operating characteristics of the boiler on which it will be used. Boiler tubes are manufactured by our sister division TEKtube and finned tubes are produced by our other sister division KFP. Our units are fabricated in our 88,000 sq. ft. state-of-the-art facility by our own shop personnel and designs and drawings are generated by our employees in our Engineering department. We have control of every aspect of the process!

We have a Fintube Economizer for every application.
