2. See Figure 8.1A.
G. Once all safety provisions are made, the temperature control set
point may now be lowered to the desired operating temperature.
H. WARNING: do not use any type or brand of automotive antifreeze.
Automotive antifreeze contains corrosion inhibitors - silicates -
designed for compatibility with the materials in automotive engines.
Unfortunately, silicates can gel and cause deposits to foul and
insulate heat exchanger surfaces. In your chilling system that
can mean higher energy costs, high pumping costs, and possibly
even shut downs for system cleaning. We recommend the use of
DowFrost or Monsanto DFS-1.
