FF Model

AXH air-coolers Type FF is a forced draft, multiple-fan, vertical discharge design with a lower profile that is ideal for large HP applications while providing bonus features at a cost that compares favorably to a large single fan vertical discharge cooler.

AXH air-coolers: FF Model

Advantage Summary

  • Inherently more efficient Forced draft design
  • Ideally suited for multiple services including engine utility cooling along with oil and multi-stages of gas compression
  • Narrow width and lower profile
  • Section design facilitates piping
  • Single, fan shaft design
  • Enhanced safety with excellent visual inspection and access to critical moving parts

Low-profile Design and Narrow Width

The Type FF design is ideal for large HP applications where a single fan cooler is unable to meet the application requirements due to physical size limitations. The lower profile and narrow width can simplify shipping and reduce transportation costs due to special routing or when compared to multiple coolers. Site plan area can often be reduced in multiple unit installations.

Multiple-Fan Design Provides Flexibility And Reliability

By using multiple fans with individual plenum chambers each fan bay can be isolated thus offering continued operation in the event of a fan or bearing failure. Fans can also be isolated during cold weather operation to reduce parasite fan HP and provide better air and temperature control. Models range in fan size from 48″ to 144″ incorporating up to five fans.

Functional Design Cuts Piping Costs

Normal design procedures used in the rating process facilitates piping. This results is nozzle arrangements that reduce piping costs. The design provides for greater accessibility to piping, drive, bearings and coils. The added open, drive-end space makes engine inspection and maintenance easier which can accommodate the installation of other equipment thus maximizing use of skid space. When installed on a common single skid it can eliminate the expense of a separate “T-skid” as well as the inconvenience and costly drive and piping disassembly and field reassembly in many applications.

 

  • Drive Options: Although normally V-belt driven from the engine or compressor the Type FF can be provided with an electric motors, hydraulic drives or even small gas engines
  • Efficiency in Cold Weather: Fans can be isolated during cold weather to reduce parasitic fan HP, enhancing air and temperature control for better performance.

Improved Safety And Maintenance

A forced draft design is considered to be safer with the fan working against a positive static head of pressure between the fan and coils. Both fan and bearings are located in cool ambient air and provide for visual inspection and easy access provided for maintenance of all moving components.

  • Warm air recirculation system

When to Choose the FF Model Heat Exchanger

Forced draft, multiple-fan, vertical discharge air cooler with a lower profile

Widely used in industries such as power generation, oil and gas, and chemical processing, where efficient heat dissipation is crucial, the FF model provides excellent cooling performance while maintaining a compact, low-profile structure. When deciding whether our FF Model heat exchanger is the right choice for your application, consider its strengths in handling large horsepower (HP) applications, particularly where a lower profile and multiple-fan, vertical discharge design are important. The FF vertical air cooler excels in environments that require efficient cooling with the added bonus of reduced height, making it the perfect choice for installations with space constraints. Its cost-effectiveness, especially when compared to large single-fan vertical coolers, makes it an attractive option for projects where both performance and budget are key considerations.
