Hot Oil Heat Transfer Systems

At their core, Hot Oil Heat Transfer Systems work by circulating a heat transfer fluid (hot oil, thermal fluid, etc.) through a closed-loop piping circuit. This circulating fluid allows for the transfer of energy from a source to a product or process (heating), and also sometimes for transferring that energy away (cooling).  Hot Oil Transfer Systems give you precise control of temperatures in a batch or continuous process and can operate at temperatures higher than steam (up to 750°F) with lower pressures, meaning no boiler attendant is needed.

HEAT is an industry expert with more than 100 years of combined experience designing Hot Oil Heat Transfer Systems—our Sales Engineers will help you choose the hot oil transfer system that is best for you. Depending on your needs, one of our Pre-Engineered Hot Oil Systems could help meet your time-sensitive demands, or a fully custom hot oil system that incorporates the additional control and safety features your process requires will be the best solution. Custom designs can incorporate your available utilities (electric, natural gas, steam, central plant hot oil loops, etc.) and are offered at 4 different levels of our custom design process, all with a dedicated project manager.

One common misconception is that hot oil heat transfer systems are unsafe–in reality, hot oil systems are much safer than other types of heat transfer systems at elevated temperatures because they can operate at much lower pressures and with higher flow rates. As long as proper considerations are made in the design and implementation of the system and the thermal fluid is properly cared for, a hot oil system is a low-maintenance solution that will perform safely and reliably for many years.

Safety is HEAT's highest priority: all our designs are built to exacting codes and standards. Piping connections are all-welded or flanged and insulated with non-wicking cellular glass insulation. Every system is rigorously tested during our Factory Acceptance Test process, which you can witness in person or virtually. Our Service and Aftermarket teams are dedicated to providing you on-site equipment start-up assistance, training, troubleshooting, and spare parts support. We also offer preventative maintenance and fluid care help to keep your hot oil system running safely and at peak performance.

We divide our hot oil system designs into categories based on the heat source. Learn more below!
