  • Optimum Heat Exchanger Performance Depends on Clean Tubes
    Optimum Heat Exchanger Performance Depends on Clean Tubes

    by Jennifer Larson – JetNews magazine, October 2015. This article discusses the correlation between heat exchanger tube condition and unit performance, types of deposits and the procedures to mitigate the fouling.

  • Conco U-Tube Cleaning System
    Conco U-Tube Cleaning System

    The fouling of U-Tube Heat Exchanger ID’s not only has a negative impact on heat transfer efficiency, but also may restrict the output or production capacity of the facility and data acquisition for non destructive testing of the unit. Traditional tube ID cleaning methods include the use of high pressure water and or chemicals. However, this can not only be dangerous, it also does not completely remove the majority of the deposit from the unit. As a result, Conco has developed and facilitated a mechanical cleaning method that can completely remove the deposit from the unit that is safe, efficient and cost effective.
