ALCO™, ALCO-TWIN™ Hairpin Heat Exchangers



ALCO Products™ has been a leader in the hairpin heat exchanger industry and has solved the industry's most demanding heat transfer problems. The ALCO™ designs -Double-Pipe & Multi-Tube - with either bare or longitudinally finned tubes, will provide you with the most economical solution for your heat transfer applications.

  • Design
    ALCO™ hairpin exchangers offer true counter-current flow and permit extreme temperature crossing and close temperature approach.

  • Pressure
    Design pressures in excess of 10,000 psi are available.

  • Temperature
    Most ALCO™ exchangers can handle extreme temperatures and wide temperature differentials without the use of expansion joints.

  • Serviceability
    ALCO™ exchangers have a separate shell and tube side seal configuration. This makes the tubes very easy to inspect, remove, clean, and replace. Minimal downtime because replacement parts and gaskets are in stock.

  • Flexibility
    Modular design allows additional sections to be added to meet increased process requirements, or the rearrangement of sections for new services.

  • Delivery
    Quick delivery due to standard, on-the-shelf components.

  • Economy
    Because budget is always a major consideration, we can fabricate standard units up to sixteen inches in diameter from economical stock components. ALCO™ hairpin exchangers offer high surface areas with small diameters, providing a more economical alternative to Shell and Tube Exchangers.


Ideal Applications For ALCO™ Hairpin Heat Exchangers:

  • Temperature Cross
  • High Tubeside Pressure

  • Complete Vaporization Requirements
  • Exchangers subject to Thermal Shock
  • High Terminal Temperature Differences



  • Multi-tube
  • Double pipe



  • Severe service (separated closure)
  • Heavy duty (separated closure)
  • Double pipe

Detachable U-bend cover for access to removable tubes.
