ADVANTAGES

  • Operates in true counter current flow permitting extreme temperature cross.
  • Economically adaptable to service differentials.
  • Ideal for wide temperature ranges and differentials.
  • Standard double pipe or multi-tube design reduces engineering, thermal design,
    drafting and shop fabrication costs.
  • Provides shorter deliveries than shell and tube due to standardization of design and construction.
  • Resistance welded longitudinal fintubes utilized for high heat transfer efficiency.
  • Available in a wide range of sizes to meet most process requirements.
  • Multiple sections shipped completely assembled and ready for process piping connection.
  • Can custom engineer equipment to meet any process or piping requirement.
  • All hairpin heat exchangers are A.S.M.E. inspected and Code stamped.

The Holland Petrofin Patented Closure

  • The most efficient seal on the market.
  • Guaranteed against interstream leakage.
  • Allows for more tubes in a given shell size
    resulting in more heat exchanger for the same competitive dollar.

The Holland Petrofin Patented Closure

  • Contains separate flanges and bolting for each
    sealing surface.
  • Can handle all applications in severe service.
  • Recommended for pressures above 2000 psig,
    cyclic service, low temperature service, extreme temperature differentials and hard to hold fluids.
