1.6. Insulation
A. Chillers are built with factory installed insulation on any
surface that may be subject to temperatures below the
room dew point.
1.7. Brine Applications
A. Applications where the leaving fl uid temperature goes
below 40°F a suitable brine solution must be used.
Failure to do so can cause immediate damage to the
system. The brine must be approved for use with heat
exchangers. Automotive antifreeze solutions are not
suitable for use in brazed plate heat exchangers.
B. The freeze detection must be adjusted appropriately
for brine applications. The brine solution
concentration should be at least 15°F below the
lowest leaving fl uid temperature.
