UTR1 - U-Tube Recovery 1 Cogeneration Series

For Large Engine and Compact Design

Cain Industries UTR1 - U-Tube Recovery 1 Cogeneration Series

The UTR1 is applied primarily where confined area restrictions vs. heat transfer requirements must be considered as a priority to the combined features of the HRSR. Its compact industrial design allows for maximum BTU recovery relative to the space allotted for installation. Finned tube spacings range from bare tube heating surface up through 8 fins per inch, depending on the fouling factor requirements. Standard fin to tube attachment using the nickel braze/weld fin to tube process allows no fin to tube separation to 2,000°F.

The UTR1 can be located above the engine or on the floor for convenient installation. With over 170 standard configurations to choose from, the UTR1 can be designed to meet the closest pinch point requirements when installation space is not an issue. Easy access allows for quick removal of finned tube rows or core assemblies without disturbing the exhaust gas connections and allows for routine inspections and/or cleaning requirements.
