Enerquip understands the distinct challenges and priorities behind designing shell and tube heat exchangers for the refining and gas processing industries. Rigorous safety standards and 24/7/365 operation requirements make it critical that heat exchangers are designed properly and comply with ASME Code, TEMA-R guidelines and API-660. We work with our customers to customize heat exchangers to their specifications, taking into consideration cost, space constraints and corrosion resistance.
Nearly all aspects of the shell and tube heat exchanger can be customized, from the number of tube passes to the size of the tubes themselves. We strive to design your exchangers to be easy to clean, inspect and maintain, and can suggest design features such as davit arms and hinge assemblies for safer removal of channels and covers. Sizes range from 2-inch to 54-inch diameters with tubes as long as 60 feet.
In addition to refining and petrochemical, Enerquip has many customers in the ethanol market. As original exchangers (often built from corrosive carbon steel) wear out, plant managers and their engineers turn to Enerquip to design replacement reboilers, evaporators, preheaters and condensers that have a more robust stainless steel design. As new processes are incorporated for recovering oils, using additional parts of the kernels and stalks for cellulosic ethanol, and additional distillation for valuable by-products take place, Enerquip often provides the pilot scale heat exchangers to help prove out these processes. Once the process is shown to add value, Enerquip helps the system OEM’s design the shell and tube exchangers for demonstration scale and commercial scale processes.
Another growing sector that values Enerquip’s expertise is the collection and processing of landfill gas. Enerquip has designed shell and tube heat exchangers for cooling and condensing the gas streams, and for vaporizing and heating gas through the various stages of compression and purification. Our exchangers typically have 316L stainless steel product contact surfaces to protect against trace corrosive elements in the gas. There is often a need for high pressure in parts of this process, and Enerquip’s ASME Code stamp enables us to provide exchangers rated up to 3000 psig. In addition, Enerquip has experience with designing exchangers for vacuum conditions, understanding the factors in heat exchanger design that impact pressure drop and boiling point.
Biodiesel processing utilizes many shell and tube heat exchangers for preheating, cooling and condensing product streams and waste vapors throughout the process. Fats, glycerines and oleolipids can be challenging to pump and to heat/cool without fouling. Enerquip’s experts have helped our customers in this industry optimize their heat exchanger designs to maximize thermal efficiency, while making the exchangers easier to maintain during periodic cleaning.
We can help you find or customize exactly what you need for your operation, with a lead time half that is typically better than the industry standard. There are many ways we can customize your equipment to make it more efficient to use and to maintain.

Shell & Tube Heat Exchangers used in Refining and Renewable Energy
Product preheaters are often used to capture heat from one part of the process to add heat to a product stream prior to evaporation or reboiling stage, in order to save on energy. Preheating is also easier on equipment, reducing the effects of shock from sudden temperature changes that can be damaging. Air Preheaters are mainly used in fossil …
Most reboilers are made with shell and tube heat exchangers and are typically used in distillation processes. Boiling liquid from of the bottom of industrial distillation columns, reboilers generate vapors that are returned to the columns, driving distillation separation. The same heat from the reboiler at the bottom of the column is …
Shell and tube coolers can be used in numerous applications throughout the refining process, and can be designed in many configurations. Products heated during processing often require cooling before they can be packaged or piped for distribution. Often waste streams also need to be cooled before entering sewer systems or rivers in …
Implementing heat recovery exchangers in your production process will help to increase plant efficiency, and decrease your energy costs and carbon footprint. Using recovery heat exchanger and transferring heat into other process area is a basic method to increase production of the plant, or decrease fuel consumption.
Enerquip Product Offerings to the Refining & Renewable Energy Markets
Custom Sanitary Shell & Tube Heat Exchangers
Enerquip’s design experts and engineers have experience in custom heat exchanger design in a wide variety of industries. 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 with the fastest lead times in the industry.
REPLACEMENT TUBE BUNDLES
Enerquip understands that a leaking heat exchanger tube bundle can result in contaminated product and costly down-time. That is why Enerquip stocks several sizes of replacement tube bundles and O-rings for immediate delivery. Enerquip can also supply replacement bundles for competitor’s heat exchangers, often faster than they can.
Commercial Grade Shell & Tube Heat Exchangers
Enerquip has a line of commercial grade shell and tube heat exchangers for when your heating and cooling applications do not require sanitary surface finishes.
Compact Shell & Tube Heat Exchangers
In certain situations, a typical shell and tube heat exchanger is too large or doesn’t support the type or volume of product you need heated or cooled. In these situations, a compact shell and tube heat exchanger can offer a tremendous advantage.
In addition to the many styles of shell and tube heat exchangers Enerquip offers, we also provide a line of bayonet heaters. Designed to efficiently heat entire tanks of fluid, our bayonet heaters efficiently transfer heat to large quantities of liquids, making them cost-effective for temperature regulation of process solutions, oils, and more.
