Chart Core-In-Kettle heat exchangers look and operate like "kettle" type shell-and-tube heat exchangers but they operate more efficiently. In Chart's Core-In-Kettle design, tube-bundles are replaced with brazed aluminum plate-fin "cores" which are smaller, lighter, and pack in about ten times more heat transfer surface area than comparable sized shell-and-tube exchangers, and up to twenty times more "UA" because of higher heat transfer coefficients.

Improve Efficiency and Economy 3 Ways

High performance Chart Core-In-Kettle heat exchangers will greatly improve the efficiency and economy of chillers, vaporizers, reboilers, and condensers. In fact, the Chart Core-In-Kettle design is so efficient that tight approach temperatures down to 2.0ºF (1.1ºC) may be used. Using approach temperatures like these can increase plant capacity, reduce horsepower, or both, and save costs three ways:

• The tight approach temperatures permit designing a process remarkably low in horsepower, one that will substantially reduce energy operating costs.
  
• Reduced horsepower requirements allow smaller, less costly compressors for additional installed cost savings.
  
• And, Chart's Core-In-Kettle's small and lightweight package can be easily installed in less space, with less supporting structure, less insulation, a smaller plot plan, and with lower cost than any similar capacity shell-and-tube heat exchanger or multiple heat exchanger unit.

Retrofit and Increase Capacity at the Lowest Possible Cost

Increasing plant capacity is easy and economical with Chart Core-In-Kettle heat exchangers.

Increases to plant capacity can involve a trade-off between increased compression or increased heat exchange. Plant retrofits utilizing Chart's high efficiency Core-In-Kettle heat exchangers will often handle the necessary increases in plant capacity without additional compression. Existing plant compressors may then be used, thereby saving the substantial costs of additional compression.

Use Existing Shells

Shell-and-tube heat exchangers may be converted in the field to Core-in-Kettle designs with a minimal amount of effort. The time to remove existing old tube-bundles, rework existing shells, and install Chart's exchanger cores is very short. The use of existing shells means firsts costs, installation costs, and operating costs will be significantly reduced.

Clearly, for tube-bundle replacements in existing kettle type shell-and-tube heat exchangers, chart's Core-in-Kettle design may provide a very wise and cost-effective rationale for making a retrofit decision now
