Axh Air Coolers

The most respected and prevalent engine driven cooler design in the gas compression industry. A superior design proven in tens of thousands of installations worldwide.

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
• High vertical discharge air velocity results in the cooler being less affected by wind direction or adjacent equipment
• Sloped sections result in greater cooling capacity in a smaller footprint or plot area
• Elimination of “top-heaviness?means greater safety, stability, and ease of handling
• Superior air-flow minimizes hot air recirculation
• Enhanced safety with excellent visual inspection and access to critical moving parts

Efficent Forced Draft Design

The advantage of AXH air-coolers EF forced draft, vertical discharge design is that fan handles cool, denser ambient air. As a result, the fan is inherently more efficient requiring less fan horsepower than induced draft coolers handling hot discharge air. Superior air flow further minimizes the recirculation of discharge hot air making it virtually unaffected by variations in wind direction or the location of adjacent equipment. 

Sloped Sections with Superior Weight Distribution

The Type EF's design offers combined engine and compressor cooling with multiple stage gas services in a single structure. A primary advantage of the cooler's sloped section arrangement is that it provides greater cooling capacity within a given frame size with a compact “footprint?which in turn reduces the required skid or pad space. The "top (front) heaviness" of an induced draft cooler is also eliminated with the center of gravity located close to the physical center or the cooler, resulting in greater safety and stability in handling. 

Drive Options

Normally V-belt driven from the engine or compressor the EF can also be provided with an internal electric motor or other type drives. 

Integral Shutters

Adjustable aluminum shutters are a standard feature on most Type EF coolers. Shutters provide superior air-flow characteristics and improved operating efficiency. Individual manual operators with remote linkage or optional air motors provide added temperature control by allowing independent louver adjustment over individual services. 

Improved Safety And Maintanence

A forced draft design is generally 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 cooler ambient air and are easily visible for inspection and easy access for maintenance of all moving components. 

Options

Auxiliary louvers, located on the air Inlet side, can provide greater control of fluid outlet temperatures and can be automated. "Soft" quickly removable bug screens, discharge or personnel guards, access ladders and warm air recirculation systems are common optional features.

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

Advantage Summary

• Combined engine, compressor, and multiple-stage gas cooling in a single multiple fan unit
• Forced draft design is inherently more efficient
• Narrow width and lower profile
• Section design facilitates piping
• Single, fan-shaft drive
• Improved 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. 

Efficient Forced Draft Design

The FF is a forced draft, vertical discharge, multiple-fan design is that it is inherently more efficient in which the fan handles cool, dense ambient air. As a result, the fan requires less fan horsepower than an induced draft cooler. 

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. 

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. 

Options 

Adjustable aluminum shutters are an option on all Type FF coolers. Shutters with remote linkage provide superior air flow characteristics and improved operating efficiency. Individual manual operators or optional air motors provide temperature control by allowing independent louver adjustment over separate services. Bug screens, hail or discharge/personnel guards, access ladders and warm air recirculation systems are common options.

Advantage Summary

• Offers combined engine, compressor, and multiple-stage gas cooling in a single unit
• High vertical discharge air velocity results in the cooler being less affected by wind direction or adjacent equipment
• Greater accessibility to sections
• Superior air-flow control improves process operation

Vertical Discharge Design 

The induce draft Type VI design offers combined engine and compressor cooling with multiple stage gas services in a single structure. It minimizes hot air recirculation due to its vertical discharge design and is virtually unaffected by variations in wind direction or the location of adjacent equipment in applications requiring induced draft cooling. 

Section Accessibility 

The Type VI's design provides greater section accessibility in applications requiring section replacement or change out. All sections are equipped with integral core guards for maximum protection of the exposed sections. 

Superior Temperature Control 

Adjustable aluminum shutters are an optional feature on all Type VI coolers and are located on the air inlet side of the sections for improved control of fluid outlet temperatures. Manual or automated shutters with remote linkage provide superior air-flow control and improved operating efficiency by allowing independent louver adjustment over separate services. 

Drive Options 

Normally V-belt driven from the engine or compressor the VI can be provided with an internal electric motor or hydraulic drive. 

Inspection And Maintenance

Forced or Induced Draft Design 

Type VV coolers are available in either a forced (VVF) or induced draft (VVI) configuration with horizontal air flow and can be configured to meet individual installation requirements. Propeller type air-foil fans with either fixed or adjustable pitch result in higher efficiency and lower fan horsepower.
