Flexibility to meet current air quality requirements. BRYAN BOILERS Originators of the Flexible Water Tube design

2 Bryan Triple-Flex TM Series Gas Fired Flexible Tube Boilers Efficient Water Tube Design The Bryan Flexible Water Tube provides for maximum heat transfer and the highest operating efficiency. No Thermal Shock The flexibility of the bent water tube design eliminates all possible damage from Thermal Shock and from stresses caused by poor or unequal internal circulation. This is particularly important with forced hot water heating systems designed for higher temperatures and greater temperature drops. Compact Minimum Floor Space Reverse construction option allows boilers to be installed with minimum floor space. Shipped completely assembled and wired. Tubes are easily removable and replaceable, requiring little service space.
