-
Remote Installation
The Type ZF are commonly used for large hp or process applications where remote “off skid” installation is required. Structural design ensures optimum sizing of end and center panels to support all dead loads of cooler sections and piping in accordance with API and are designed to withstand 125 mph wind loading. Structural analysis for high loads available upon request. The self-contained design eliminates the need for costly field assembly and reduces transportation costs while meeting the most severe installation requirements.
-
Forced or Induced Draft Design
Horizontal coolers are normally more efficient, forced draft designs but are alternately available in induced draft configurations with higher exit velocities. All are vertical air flow to minimize recirculation of hot discharge air. Models are available with single or multiple fans ranging in sizes from 24 to 192. Their design and size flexibility enables them to be used in a wide range of special applications.

Section Accessibility & Functional Design
- Section Accessibility & Temperature Control: The horizontal Type ZF design provides section accessibility in which all sections are equipped with lifting lugs and core guards for maximum protection of the exposed sections. Manual or automated aluminum shutters are an optional feature on all ZF models, offering improved control of fluid outlet temperatures and operating efficiency by allowing independent louver adjustment over separate services.
- Functional Design Cuts Piping Costs: Normal design procedures used in the rating process facilitate piping, resulting in nozzle arrangements that reduce piping costs. The design provides greater accessibility to piping, drive, bearings, and coils. The added open, drive-end space makes engine inspection and maintenance easier, accommodating the installation of other equipment and maximizing the 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 and Maintenance
- Drive Options: Fans are normally driven by integrally suspended electric motors using HTD or V-belts but can be adapted to a variety of alternate type drives. These include right angle gears in larger fan hp applications, internal, direct, engine jack shaft, or hydraulic drives. All drives are integrally mounted, aligned, and test run prior to shipment.
- Inspection and Maintenance: Type ZF coolers offer convenient accessibility to all components, with fan, drive, and bearings all located in cooler ambient air for increased operating life. For safety and easy maintenance, all units have individually removable fan and drive guards that meet all state and OSHA regulations. The coolers also include louvers and remote lubrication fittings.
When to Choose The ZF / ZI Models
Efficient Horizontal Air Coolers with vertical air flow
For industries such as oil and gas or power generation, the ZF and ZI Model air coolers provide exceptional cooling efficiency for a wide array of applications. These horizontal air-coolers are specifically designed for large horsepower (HP) or process applications where the cooler needs to be installed remotely, away from the main equipment (“off skid”). These air coolers are built to comply with API standards and capable of withstanding wind loads up to 125 mph, which means durability and reliability, especially in harsh and challenging environments. This design ensures that the air coolers can maintain structural integrity and continue performing optimally even under extreme weather conditions. Trust AXH Air-Coolers to keep your operations running smoothly with the superior capabilities of our ZF and ZI Models.
