When choosing which low temperature heat transfer fluid to use for your process, data such as density, viscosity and pour point need to be taken into consideration. In Process Cooling’s annual Cooling Capabilities Chart on Low Temperature Heat Transfer Fluids, we have compiled all of the data you need to choose a fluid for low temperature heat transfer fluid processes.
Thirty years ago, heat transfer fluid (HTF) manufacturers would sell virgin fluids at inflated prices and dispose of the used thermal fluids without regard for the potential of remediating the used fluid. Times have changed.
A partnership between Goodway Technologies and Multistack, a manufacturer of chiller systems, is intended to simplify the selection of cleaning chemicals for ensuring heat transfer and efficiencies remain optimal. Owners of Multistack chillers can use an online tool from Goodway to identify the type and amount of cleaner to use as well as how long to circulate the cleaning fluids.
Freeze drying is a dehydration technique commonly used in food processing as well as biological, pharmaceutical and biomedical applications. In these technical scenarios, the application of heat for evaporative drying will either degrade the material to be dried or change its form and structure (Zhang et al., 2018).
Editor Linda Becker and Austin Memmo, an application engineer with API Heat Transfer, talk about tips for selecting industrial process heat exchangers, including shell-and-tube, plate-and-frame, and shell-and plate designs.
Shell-and-tube heat exchangers — first introduced in the 1900s — have long been used in all types of process applications because of their robust design. Shell-and-tube heat exchangers are able to withstand high pressures and temperatures, and these features are among the reasons for their wide use.
The RHD Series has a continuous scraping action to enhance the mixing of viscous products. Its sealing system allows for the removal of individual tubes for cleaning or maintenance while offering increased strength.
Goodway Technologies, Stamford, Conn., and SWEP have formed a partnership to offer descaling solutions for SWEP industrial heat exchangers to help processes maintain efficiency and optimal heat transfer.
Specifications for Calflo, Petro-Therm and Purity FG HTF heat transfer fluids, manufactured by Petro-Canada Lubricants Inc., have been added to aspenOne Engineering software. The companies expect the additions to the Aspen HYSYS and Aspen Plus modeling software to provide engineers with a range of solutions when designing a heat transfer system.
