Process shell-and-tube heat exchangers

About Alfa Laval Olmi

Having produced heat exchangers for high temperature and high-pressure applications for more than 80 years, we know how to design, manufacture, commission and service your next heat exchanger for maximum efficiency and reliability.

Each Alfa Laval Olmi heat exchanger is custom made and draws on the full body of application knowledge that we have built over the decades. We make sure your heat exchanger provides low costs, great performance and a long service life by optimizing it according to your specific requirements and operating conditions.

World-leading engineering expertise 

With a full team of thermal and mechanical design experts on board, our engineering department can take on your most complex heat exchanger design challenges. Working together with our welding and manufacturing experts, they push the design
boundaries and come up with new, smart solutions that result in higher reliability and lower investment costs.

Our engineers can advise you on the best materials to use based on your operating conditions and process media. They help you find the materials that offer an optimum balance between CAPEX and OPEX by performing a total cost-of-ownership analysis.

Welding – our core competence

The durability of a heat exchanger operating at extreme conditions is highly dependent on the quality of the welds. Even minor imperfections can cause breakdowns and costly service stops. 

Our welding engineers and welding coordinators are all EWE and EWT certified. Our welders are all EN and ASME certified and are experts in welding exotic materials and joining dissimilar materials. 

Testing

We perform rigorous pre-delivery testing on every heat exchanger that leaves our workshop. Our inspectors are certified to NDE Level II and III according to SNT TC1A and EN9712. We perform a range of non-destructive tests including ultrasonic NDE, X-ray and gamma ray tests, hydro tests, pressure tests using helium, and dye penetrant tests.

For the toughest applications

Alfa Laval Olmi heat exchangers are used in some of the most demanding positions in petrochemical plants, refineries, oil and gas production facilities, and power stations around the world. Year after year these process-critical units continue to deliver high performance and stable operation.
