API 661 Air Cooler

Our standard Air Coolers comply with the API 661 standard for Air-Cooled Heat Exchangers. Since this is our standard, we are used to handling specifications and regulations in the design of our equipment.

We design and implement customized Solid Block Header Air-Cooled Coolers for the petrochemical industry. This type of header is preferred in applications with high pressures and/or extreme temperatures and whenever API 661 compliance is required.


Our API Air Coolers are designed to fit the customer’s requirements

The API 661 standard is a design basis for customer-specific equipment. This can be combined with requirements such as high pressure, low noise or minimal pressure drop.

Pressure up to 1,000 bar

Conventional welded plug type header design leads to manufacturing challenges in high-pressure applications. Our Solid Block Plug Type Header is proven up to 1,000 bar.

Low-noise construction

As Air Coolers are located outside, sound requirements can be strict and limiting in the design. Our special low-noise design limits the noise without losing performance.

Minimal pressure drop

By minimizing the tube side pressure drop in our Air-Cooled Heat Exchangers, the power consumption of the pumps can be reduced on-site.

API 661 Air Coolers for the petrochemical industry

Petrochemical companies are constantly looking for solutions that help meet today’s challenges when it comes to high quality, high pressure and temperatures, and less corrosion.

Bronswerk Heat Transfer offers all types of API 661 Air Coolers that meet those challenges.

API 661 compliant & project specific

Bronswerk Heat Transfer knows the special demands of applications for API 661 Air Coolers in the oil & gas and the petrochemical industry: thermal equipment should not only withstand corrosive media and environments but also has to be extremely reliable.

Every order starts with a detailed analysis of the specific needs of the customer. This allows us to develop a proposal that offers alternative or improved innovative solutions for our customer’s original request.

For this reason, we developed Solid Block Headers for Air Coolers that can withstand high pressures and extreme temperatures. The Solid Block Header meets all API 661 requirements and can be used in the most extreme conditions. 

Furthermore, we optimized the thermal and hydraulic design to offer you the best solution at the best price, meeting compactness and maintenance requirements.

Since 1940, Bronswerk Heat Transfer has continued to develop innovative, customized new products and assists in improving the efficiency of existing plants.
