For an accurate thermal design, please provide:

  • Process-fluid and any contaminants

  • Allowable pressure drop

  • Preferred tube or fin materials

Air-cooled Heat Exchangers

Fabsco air-cooled heat exchangers (ACHX) use ambient air to pull heat from a liquid or gas stream.  These exchangers can be either horizontally or vertically configured, with either forced or induced draft air.  ACHX requires no cooling water, and operational costs are lower than other types of exchangers.

Applications & Industries Served

Fabsco air cooled heat exchangers are primarily used in several applications, including

  • LNG pre‑treatment

  • Natural‑gas‑liquid (NGL) cryogenic processing

  • TEG dehydration & condensate re‑boil

  • Amine treating / H₂S removal

  • Gas‑compression after‑coolers (up‑stream)

  • Mid‑stream gas‑plant cooling

  • Refinery & petrochemical bundle retrofits (down‑stream)

  • Power generation & industrial refrigeration

Why Choose Air‑Cooled Heat Exchangers?

  • Zero water use – no chemical treatment or blow‑down.

  • Lower operating expenses compared with shell‑and‑tube or evaporative systems.

  • Quick‑turn spare parts and bundle replacements, supported by a dedicated aftermarket team.

  • Field‑friendly maintenance—fans, drives, bundles, and other components are designed for straightforward replacement.

Need a niche solution? Fabsco’s engineering team routinely re‑rates or re‑tubes bundles for geothermal, carbon‑capture and flare‑gas recovery projects.
