TEMA Advantage

Choosing the right supplier is an important and difficult decision. Users need to be absolutely sure that their manufacturer is reliable, producing heat transfer equipment that is safe, effective, and economical. Considerable time and money are spent having a heat exchanger designed and built to exact specifications, design codes and requirements. Why not go with a manufacturer you know you can trust?

These days, the term "quality" is so often used that it can be more a buzzword than a reality. It's comforting to know that there actually are ways to gauge quality assurance. In the tubular exchanger industry, TEMA® is the measure of quality and integrity.


The Tubular Exchanger Manufacturers Association, or TEMA, is a group of leading manufacturers who have pioneered the research and development of heat exchangers for over sixty years.

Founded in 1939, TEMA has grown to include a select group of member companies.

If you're not familiar with TEMA, perhaps you should be. In an opinion survey of purchasers and engineers, almost 70% of respondents found it "important" to do business with a TEMA manufacturer, and an over-whelming majority feel more confident in dealing with a TEMA member.

Although it may be easy to choose a TEMA member as a supplier, it is not easy for manufacturers to become a TEMA member. It takes more than just purchasing a standards manual. Many people are unaware that member companies must meet stringent criteria to even qualify for TEMA membership. Members adhere to strict specifications that may even surpass your own requirements.

When you go with a TEMA company, you can rely on quality thinking as well as quality equipment.

TEMA members develop and update today's standards, they don't just abide by them. When you select a TEMA manufacturer, you work with confidence.

TEMA Standards and Software have achieved worldwide acceptance as the authority on shell and tube heat exchanger mechanical design. These tools give engineers a valuable edge when designing and manufacturing all types of heat exchangers.

TEMA Name Plate

Nine editions of TEMA Standards have been published, each on updating the industry on the latest developments in technology. In an opinion survey of TEMA Standards purchasers, ninety-seven percent rated TEMA Standards as "good to excellent".

TEMA has also developed engineering software that complements the TEMA Standards in the areas of flexible shell elements (expansion joints) analysis, flow induced vibration analysis and fixed tubesheet design and analysis. This state-of-the-art software features a materials data-bank of 38 materials, as well as user-friendly, interactive input and output screens. The programs handle many complex calculations, so users can focus on the final results.

Being the best is never easy. In fact, before a company can even become a member of TEMA, it must have a minimum of 5 years of continuous service in the manufacture, design and marketing of shell and tube heat exchangers. All TEMA companies must have in-house thermal and mechanical design capabilities, and thoroughly understand current code requirements and initiate strict quality control procedures.

Additionally, all welding must be done by the company's own personnel, and the company must have its own quality control inspectors. These criteria ensure the highest level of technical expertise, which gives TEMA members a meaningful advantage when designing or fabricating heat exchangers.
