needs

WOrldWide MAnuFActuring cApAbilities

AirFin derives maximum advantage from its interna-

tional manufacturing and service

organization. As a result of this worldwide sourcing,

customers derive economic benefits from advanced

product design and cost

optimization.

SPX Cooling Technologies offers products manufac-

tured at our own facilities in Germany, South Africa

and China. Additionally, our alliance partners in

North America, South America and other

countries provide a "competitive edge" and a unique

flexibility in meeting our clients' requirements.

AdvAnced reseArch And technOlOgy

AirFin benefits from the advanced research facility

at SPX Cooling Technologies in Germany. Ongoing,

aggressive research and development assures the

division’s position as a market leader in technology.

The primary marketing objective is to identify new

QuAlity AssurAnce And QuAlity cOntrOl

Quality Assurance and Quality Control programs

are certified to ISO 9001, TUV, and others. The

testing and verification process is rigorous, while

our certified inspection programs meet or exceed

industry standards. Testing includes hydrostatic,

pneumatic, and/or submerged underwater leak

testing, as well as nondestructive and specific

testing per project specifications.

In addition, all materials are inspected upon

receipt, in-process, and at final assembly stage.

Additionally, AirFin quality programs include third-

party independent inspections when necessary.

heAt exchAngers

SPX Cooling Technologies has over 40 years

of experience in the design and manufac-

turing of air-cooled heat exchangers. Our

thermal designs are based on SPX Cooling

Technologies’ proprietary computer programs,

and are, as standard procedure, verified to the

latest version of widely accepted HTRI ther-

mal design software.

The AirFin air-cooled heat exchanger is designed

and manufactured as a forced draft or induced

draft type. Each tube bundle is constructed,

tested, and stamped in strict accordance with

the following rigid standards

• ASME Section VIII, Division I, with

"U" stamp

• API 661, when applicable (recommended

design practice for Refinery Application)

• TEMA, when applicable

• Additional world standards: DIN, British, JIS,

AD-Merkblatt, REGELS

• Chinese standards: GB-150, BR1, GB/

T15386, JB-4730

Project planning and implementation

processes utilize ultramodern computer software

for engineering, design and

manufacturing.

AirFin designs can be completely shop-

assembled, or pre-assembled in modular

pieces for easy on-site field erection, the choice

contingent upon optimum transportation cost

benefit to the customer. For export projects, to

ensure that your shipment arrives in perfect

condition, we offer seaworthy packing, with

nitrogen fill for long-term storage.
