Flexible fluoropolymer bundles and fused honeycomb tube sheets, in sizes for demanding process duties.
PV4 Series Shell and Tube Heat Exchangers (3 inch Shell) are small, up to 6 feet in length, affordable heat exchangers suitable for low flow applications. Their design maximizes the heat transfer performance of FEP or PFA, as well as "Q" Series fluoropolymer tubing.
Shell-and-Tube Heat Exchangers 30-Series Mid-Size (4 inch shell) are available in lengths up to 11 feet. This series uses a single-pass, typically counter-current flow design. Tube bundles are joined together to create honeycomb tube sheets. Heads are fluoropolymer-lined, and the flexible tube bundle is easily removable for maintenance.
Carbon steel shells are standard; other shell materials are available on request. Metal shells are ASME coded and feature TEMA/ANSI end nozzle connections.
Shell and Tube Heat Exchangers 30-Series Model 218, 525 and 1000 are single pass, typically counter-current-flow units designed for heating, cooling and condensing.
Flexible fluoropolymer tube bundles are joined together to form unique honeycomb tube sheets that add physical robustness.
Material choices include FEP or Q-Series tubing with PTFE-lined heads. Standard shell construction is carbon steel, with other shell materials available on request. Products are ASME coded and equipped with TEMA/ANSI end nozzle connections.
The difference between models 218, 525 and 1000 is the number of tubes per bundle, which increases the heat transfer area. Users should select the model that is right for the application based on length and heat transfer requirements.
Niche's largest heat exchangers, Shell & Tube Heat Exchangers 30 Series Large Capacity Model 900 feature 14-inch diameter shells and many fluoropolymer tubes, providing high flow capacity and low pressure drop.
Shells are available in a variety of materials, including carbon steel, fluoropolymer-lined carbon steel and stainless steel. Tube lengths are available up to 24 feet.
