Vaporizers may be fabricated in carbon steel, nickel alloys, and stainless steel. They offer multiple advantages over other HEX equipment. Our vaporizer features:

  • Freeze protection: incoming steam or heating fluids continuously heat the outgoing condensation
  • Superheat: upon request, we can add integral superheat capabilities
  • Small footprint: a vertical system takes up substantially less plot space when compared to horizontal options
  • Unlimited turndown: our systems can comfortably operate at turndown approaching 100%
  • Holdup volumes: these vaporizers retain a minimal amount of liquid, unlike alternative designs
  • Removable bundle: maintenance, inspections, and replacements are easy
