Enerquip’s design experts and engineers have experience in custom heat exchanger design in a wide variety of industries.
Custom Shell and Tube Heat Exchanger Designs
When our off-the-shelf heat exchangers won’t work for you, you can count on Enerquip to bring you an optimal heat exchanger for your application. Our team of experienced thermal design engineers will work with you to determine the best type of heat exchanger for your application. By using state-of-the-art HTRI thermal design software, Compress code software, an extensive library of past designs, and a large database of product properties, you can be confident that your exchanger is designed to meet your specific process requirements and sizing.
Stainless Steel Shell and Tube Heat Exchanger Specs
Enerquip’s shell and tube designs are manufactured to TEMA guidelines with straight tubes or U-tubes in shells, and can be built from 2” to 48” in diameter. Our custom heat exchangers can be built in a variety of materials, including 304L and 316L stainless steel, and more corrosion-resistant alloys such as Hastelloy, Alloy 20, Monel 600, AL-6XN, and Titanium. Because we are a leading provider of sanitary and pharma grade exchangers, we do not work with carbon steel in our plant to help prevent cross contamination.
Instead, our stainless steel buying power allows us to offer 100% stainless steel exchangers at a competitive and comparable price to carbon steel. This gives you higher value and lower maintenance cost on your equipment, plus a more durable and sanitary exchanger.
Stainless Steel Shell and Tube Heat Exchanger Options
Whether a new or replacement unit, once your design is created, there are many options you can select for supports for your exchanger, for surface finish upgrades, for insulation jackets, and maintenance features like hinged channel covers.

New Custom Designed Heat Exchangers
When an off-the-shelf heat exchanger is not appropriate for your needs, Enerquip’s heat exchanger experts can work with you to design the perfect heat exchanger for your application. We’ll take your product and utility data, along with your preferences on size and exchanger type, and develop a thermal model in HTRI of an exchanger that will efficiently heat or cool your product.
Enerquip will also consider:
- the level of corrosion protection needed
- surface finish requirements
- connection types
- how you intend to clean and maintain the exchanger once it is in service
Your design will be in compliance with TEMA (Tubular Exchanger Manufacturers Association), the standard for best practices in designing and fabricating shell and tube heat exchangers. Enerquip can design to TEMA C for general use, TEMA B for chemical use, and TEMA R for refining use, depending on your needs.
Enerquip will also ensure that any industry standards and regulatory codes are met during the design process. This will give you the peace of mind that your equipment is safe, and will prevent any product contamination.
All of Enerquip’s heat exchangers are designed and code stamped to ASME Section VIII, Div 1 for pressure vessels, after thorough inspection and hydro-testing under the supervision of a 3rd party inspector.
Exchangers can also be designed to ASME-BPE for pharmaceutical applications, 3-A for sanitary dairy applications, API-660 for refining applications and a wide variety of international codes such as CRN for Canada, MOM for Singapore and PED for Europe.
Reverse Engineered Drop-in Replacement Exchangers
When a heat exchanger in your operation goes down, Enerquip understands the importance of getting your plant up and running again as quickly and efficiently as possible. We realize that there are cases where a new exchanger must fit in the exact spot of your old unit. We help take the worry out of this process, by assisting you in reverse-engineering a drop-in replacement exchanger.
We can work off of old drawings, U-1 data reports, TEMA data sheets and even photos and sketches to design an exchanger with sufficient surface area to replace your old exchanger. If you have suspicions about what caused your old exchanger to fail, we can design safety features and upgrades into your new exchanger to lengthen its lifespan. Many customers take this opportunity to upgrade materials to more corrosion resistant alloys like higher grades of stainless steel. They may also add an expansion joint to protect the new exchanger from thermal expansion damage from shock or sudden start-up conditions.
To simplify the installation of your new exchanger, and ensure that it will fit correctly, you will need to provide some dimensions such as nozzle tie points, and support locations. Some customers prefer to use lapjoint flanges on their exchanger to assist with lining up the bolts between their exchanger flanges and interconnecting piping.
A Custom Exchanger for Every Industry
Custom Sanitary Exchangers
As a leading supplier to many sanitary industries, we know the sanitary requirements, understand the process heating and cooling applications, and comply with the surface finish and cleanability standards you require. Our use of stainless steel materials minimizes corrosion and increases sanitary performance of our exchangers, making Enerquip’s sanitary exchangers the industry standard in dairy, brewing, pharmaceutical, and food applications.
Custom Pharmaceutical Grade Exchangers
Our reputation for high quality and fast lead-times has earned the trust of many top companies in the pharmaceutical, nutraceutical, fine chemical, biotech, animal health and personal care industries. Enerquip’s exchangers are highly polished and designed with double tubesheets to protect from cross-contamination, which is why our exchangers play vital roles in heating and cooling WFI, blood, plasma, and growth media, formulated pharmaceuticals, waste neutralization and more.
Custom Industrial Exchangers
Because of our stainless buying power, we are able to offer a 100% stainless steel exchanger at a competitive price and lead time compared to carbon steel. Our custom industrial heat exchangers are used by many leading companies in a wide variety industries such as chemical, biofuels, petroleum refining, waste water and more.
