Custom Heat Exchangers

Where Art Meets Science

Heat exchangers have a broad range of sanitary and industrial applications. At Enerquip, our design experts and engineers have experience designing for even the toughest of applications in a wide variety of industries, from water to highly viscous fluids such as asphalt.

When your production process doesn’t require a custom solution, we stock a variety of standard sanitary U-tube exchangers and bundles for fast turnaround.

Custom Shell and Tube Heat Exchanger Designs

When custom is required, you can count on the Enerquip experts to bring you the 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.

Shell and Tube Heat Exchanger Specs

Enerquip’s shell and tube designs are manufactured to TEMA guidelines with straight tubes or U-tubes, and can be built from 2” to 48” in diameter.

Our custom heat exchangers can be built in a variety of materials, including carbon steel, 304L and 316L stainless steel, and more corrosion-resistant alloys such as Hastelloy, Alloy 20, Monel 600, AL-6XN, and Titanium.

To ensure the integrity of our sanitary and pharma grade exchangers, and to help prevent any kind of cross contamination, our carbon and stainless products are manufactured in two different facilities. Our stainless equipment is manufactured in Medford, WI, while our carbon production takes place in Beggs, OK.

Enerquip has been working with stainless steel for decades, allowing us the buying power 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.

Shell and Tube Heat Exchanger Options

Enerquip listens to our customers and anticipates their special needs for operating and maintaining their shell and tube heat exchangers. We strive to minimize maintenance downtime, while providing safe features that help your maintenance team quickly and efficiently inspect, clean and service your exchangers.

We may suggest davit arm assemblies or hinge assemblies for removing heavy bonnets, or channel covers. Other options that we provide:

    • Insulation jacket, non-asbestos and chloride free
    • Horizontal saddles or vertical mounting supports
    • Vacuum breakers, sight glasses
    • ANSI flanged, lapjoint, NPT threaded, or sanitary Tri-clamp connections
    • Upgrades to 3-A or double tubesheet design for high purity applications
    • Jaygo clamps for frequent head removal
    • Twisted tape turbulators for flow enhancement and improved heat transfer
    • Floating tube sheets or expansion joints for thermal expansion protection
    • Enhanced surface finishes, up to 15Ra Electropolished
    • Passivation
    • Davit arms (used with heavy bonnet designs)

Safety Code Compliance

You can be assured that Enerquip has your safety and the security of your facility in mind. All of our shell and tube heat exchangers are designed to TEMA (Tubular Exchanger Manufacturers Association), the standard for best practices in designing and fabricating shell and tube heat exchangers.  Depending on your needs, Enerquip can design to TEMA C for general use, TEMA B for chemical use, and TEMA R for refining use.

After thorough inspection and hydro-testing under the supervision of a 3rd party inspector, Enerquip’s heat exchangers are code stamped to ASME Section VIII, Div 1 for pressure vessels.

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

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.
