ACHE model G

Ensuring efficient and reliable cooling of your processes is key to staying productive and profitable. With ACHE model G for well-defined cooling needs, project execution has never been easier or faster thanks to the modular design, which ensures rapid ordering and delivery. ACHE model G can be used for general cooling duties in gas compression, downstream refrigeration and fuel gas compression applications.

ACHE model G is a modular air-cooled heat exchanger that provides reliable and cost-effective cooling of natural gas, water and/or synthetic oils — cooling duties that can be found around a natural gas compressor, for example. A flexible modular design allows the cooling units to be easily customized to the needs and options within ACHE model G’s design limits. ACHE model G has been designed by experts in the field — Alfa Laval Olmi — a reliable and well-known supplier of air-cooled heat exchangers to industry.

Modular design

To meet tight budgets and schedules, Alfa Laval’s engineering team has developed a modular air-cooler design. The modular design provides the flexibility to adapt to different conditions and requirements, while the pre-defined key parameters common to all ACHE model G units ensure a rapid ordering and delivery process.

Designed for easy transport

Transporting air-cooled heat exchangers can be a timeconsuming and expensive exercise, especially if the units are oversized. All ACHE model G units can be transported on a normal truck or in a 40-ft container for convenient transport to the customer’s site by land or sea.


ACHE model G is a modular air-cooled heat exchanger that is fast and easy to:

  • Size and buy—pre-configured modules in flexible configurations
  • Manufacture and deliver—pre-engineered blocks in compact design for rapid transportation
  • Erect and install—bolt down the modules, plug in the power cables, connect the flanges and start
