The MOD-U-FLOW Shell & Tube Heat Exchanger offers a wide range of benefits over conventional equipment with particular emphasis on Ease of Maintenance The tube bundle is held together with elastomeric seals which eliminate tube sheet welding and allows for complete dismantling for inspection, cleaning and individual tube replacement.High Thermal Efficiency Due to an optimum shell side velocity profile based on a baffle assembly which promotes uni-directional fluid flow with a reduced fouling effect.Fail Safe Operation A double seal arrangement eliminates cross contamination of primary and secondary fluids.Upgrade of Capacity The modular concept allows for the addition, reduction and/or re-arrangement of modules to satisfy future production variations and/or plant modifications.
