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.
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
How it works
Three simple steps
With ACHE model G, you are only three simple steps away from plugging the unit into your system. This simple procedure not only reduces the time and cost of on-site erection, but also makes installation safer.
Install and fix the module on the supporting structure
Cable motor and check belt
Match module process flanges to piping
Selected main applications
Compressing gas is demanding. ACHE model G enables robust, cost-effective solutions adapted to the pressures, gas composition and maintenance needs of the specific application. Compression skids, which are often used at the wellhead to bring natural gas to the required pipeline pressure, require purpose-built cooling solutions that withstand harsh operating conditions. Unmanned compression stations that secure pressure in a gas pipeline must operate reliably with minimal maintenance.
Refrigeration units and industrial gas compression
Refrigeration units (refrigerant condensers) and compression of industrial gas (N2 and air) has many applications in all fields; the fluids, gas or vapor involved work in cycles in a well-proven standardized package. ACHE model G meets requirements for very stable operations, contributing to the compactness of the whole system.
Synthetic oil cooling
Synthetic oils are utilized in lubricated systems and in the transfer of heat when other auxiliary fluids fail. ACHE model G, with or without inserts inside the tubes, can minimize the surface area even where fluid viscosity plays an important role, enabling safe operation and simple constructability.
Fuel gas compression
Fuel gas compression applications are often sited in remote areas where water supply is either restricted or unavailable. ACHE model G is designed to provide both interstage and discharge cooling in the compressor package.
