Different configurations and materials are used to build scraped surface heat exchangers, so that final assemblies meet the exact processing requirements for specific applications. Regardless of how devices are constructed, all pressure elements have been designed to meet the standards of current ASME codes. Exchangers can also be CE-PED certified.

Choosing the right components for devices ensures that machines run to their to optimal performance. Below, we will highlight some of the different parts that are built into heat exchangers.

Jackets: it is possible to jacket exchangers for steam, liquid, and direct expansion refrigeration.

Scraper blades: these blades are constructed on a shaft that has staggered rows. Blades are welded onto the shafts. With blades, there is no chance of build-up in threaded areas. This helps to keep the final products more sanitary. A variety of blade materials are on the market.

Heat transfer tubes: when picking these tubes, wall thickness and thermal conductivity is the most critical design consideration. The thickness of the wall is directly proportional to the heat transfer resistance. These tubes can help to maximize structural stability. Materials matter as well. Pure nickel versions have high thermal conductivity, whereas the stainless-steel type is used to enhance heat transfer.

Drives: the drive provides users optimal performance from each component. Drives help to ensure all applications are up to speed.

Seals: this component is used to make assembly and maintenance much more straightforward. It also gives users cleaner operations. Hardened surface seals offer high durability.

Shafts: A products time in a heat exchanger is controlled mainly by the volume of the unit. Smaller systems provide users with big annulus for extended residence time. Larger variants create smaller annulus and higher velocity and turbulence.
