Preparation and Startup of New Systems
This document is offered as a general guideline to starting a new or freshly filled system. Please follow proper safety procedures and consult your system manufacturer for specifics on your system and what steps need to be taken to ensure a smooth and safe startup.
Understanding Heat Transfer Fluids and Your Extruder
All hot oils (heat transfer fluids) have a limit to the time they can be utilized in an extruder. The key factor affecting service life is mainly the type of fluid being used. However, process temperatures and production rates are just a few of the more minor factors involved in determining the length of time between fluid changes.
Understanding Fluid Degradation
The scientific definition of oxidative degradation is the reaction of oxygen (in air) with the fluid by a free radical mechanism to form larger molecules which end up as polymers or solids. These thicken the fluid thereby increasing its viscosity.
Proper Fluid Maintenance and Change-Out Procedures
With literally thousands of uses for heat transfer fluids, it is nearly impossible for any heat transfer fluid manufacturer to recommend an exact oil change interval or maintenance schedule.
System Cleaners: Which One is Right for You?
Ideally you never need to clean your heat transfer system but should that time come it’s good to know you have options.
