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.

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.
