Ensuring High-Purity Standards
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 shop in Medford, WI, is a stainless-steel shop only. All carbon steel manufacturing takes in our Beggs, OK, shop.
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.
Our experienced engineers can help you evaluate cost saving suggestions on higher alloy heat exchangers, like using explosion-bonded clad tubesheets and channel covers instead of solid plates, and using lap joint flanges where appropriate, instead of solid high alloy flanges.
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 C, B or R guidelines, following best practices for thermal design and construction.
We also evaluate every design using Compress codeware to ensure that your new exchanger will meet all of the safety requirements of ASME Code, along with any nozzle loadings, seismic considerations and other site conditions that can affect the stability of your equipment. Every exchanger design is reviewed and approved by a 3rd party inspector, who also provides oversight during fabrication, and witnesses the ASME hydro-test of every exchanger. We can also design and build exchangers to API-660 and other international codes where appropriate.

Industrial Applications for Shell & Tube Heat Exchangers
As one of the most vital and widely used pieces of process equipment, every industrial process will likely involve some type of temperature regulation requiring a heat exchanger.
Industrial heat exchangers are used as components of air conditioning and cooling systems, heating systems, and are used for safe temperature regulation of machinery, chemicals, water, gas, asphalt, and other substances in industrial plants.
Enerquip’s exchangers are also often used to capture and transfer steam or heat exhaust that is released as a byproduct of a process so that the steam or heat can be reused elsewhere. This process improves production efficiency, saving the industrial plant time, resources, and money.
One of the most common uses of shell and tube heat exchangers is for the production of hot water. Water heating is an integral part of any industrial operation, so it is important to make sure you employ the proper solution for your plant. Hot water is necessary to ensure safety, sanitation, and continued operations in any commercial facility.
Water heaters rely on heat exchangers to transfer thermal energy from a heating solution to increase the temperature of water. To do this, cold water is sent through the tube side of the exchanger while steam or hot thermal oil is sent through the shell side of the exchanger.
In any water heating application, it is important to have the right components for your system to keep the heating process efficient and not lose thermal energy.
Snow Melt Pit Coils
Enerquip supplies snow melters to many OEM’s that install ice skating rinks throughout North America. Our snow melt pit coils fit neatly down inside the trench where the zambonis drop the ice shavings after cleaning off the rinks.
A series of metal grates attached to the baffles on the melter protect the stainless steel tubes from damage when the snow gets dumped on them. Hot water or steam is used to circulate through the tubes, melting the snow, which is then carried off to a drain. Because the snow pit size varies from rink to rink, these coils can be custom designed to fit the shape of the pit.
Our snow melt pit coils are made from 100% stainless steel, making them corrosion resistant and robust enough to hold up to any chemicals that may be in the municipal water.
Oil Coolers and Heaters
Nearly every industry with fluid processes rely on oil heaters and coolers for production. Enerquip’s experienced sales engineers have worked with a wide variety of thermal fluids, brines, and lubricants and can assist you in selecting the perfect shell and tube exchanger for your application.
Where boiler steam or hot gases can’t be used to heat product directly, oil heaters act as the intermediary source of utility heat. Heat transfer oil typically enters the heater through the shell side of the heat exchanger. Heat from the burner gas or steam passing through through the tubes radiates into the thermal fluid circulating around the tubes in the shell. The hot oil can then be used to safely heat product, by being circulated through another heat exchanger or tank jacket.
Used in a variety of industries from chemical plants to water treatment systems, oil heaters (and coolers) are imperative for many industrial applications.
Shell and tube oil coolers are designed to efficiently reduce the high fluid temperatures encountered in today’s machines. Many industries rely on shell and tube oil coolers, including pulp & paper converting, mining, and industrial refrigeration systems. We frequently design oil coolers for customers needing a closed loop chiller system, where thermal oil is cooled down using a refrigerant, and then used in the shell of an exchanger to cool product flowing through the tubes.
We’ve also helped customers cool hydraulic oil on everything from plastic injection molding machines, to pump skids to U.S. Navy ships.
Keeping entire tanks of these types of liquids at pumping temperatures can be prohibitively expensive. Suction heaters heat only the liquid being pumped through them instead of heating an entire storage tank of products. As a result, suction heaters are an economical, cost-effective option for plants and facilities in a variety of industries.
