Air-Cooled heat exchangers

• 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

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.

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.

• 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

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.

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.

• Self-contained design eliminates field assembly and reduces transportation costs
• Ideally suited for multiple services including engine utility cooling along with oil and multi-stages of gas compression
• Forced or induced draft configurations
• Available with single or multiple fans
• Accommodates various type drive options
• Excellent access and inspection to component parts

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.

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. Right ange gears in larger fan hp applications, internal, direct, engine jack shaft, or hydraulic. All drives are integrally mounted, aligned, and test run prior to shipment.
