NOTES:
If operation of the chiller at less than 48°F is required, an inhibited propylene glycol solution
is required.
Consult factory for chiller operation below 20°F.
Ambient conditions affect air cooled chiller operation and capacity. Standard rating is at 95°F
entering air temperature. For ambient air conditions greater than 95°F, chiller derating will
occur. For ambients over 95°F consult factory.
Standard chiller rating is at 50°F. For all other temperature settings, output
tonnage is altered as follows:
8.3 INHIBITED PROPYLENE GLYCOL
A. To operate liquid chillers below 48°F, it is necessary to add
inhibited propylene glycol to the circulating system to lower the
freeze point and prevent damage to the cooling system. Inhibited
propylene glycol contains corrosion inhibitors which are compatible
with most industrial heat transfer surfaces. Inhibited propylene glycol
is manufactured by:
• Dow Chemical - “DowFrost” (1-800-258-2436)
• Monsanto “Therminol FS” (1-800-459-2665)
•AdvantageEngineering“Thermouid”(1-317-887-0729)
B. Automotive anti-freeze must never be used in industrial heat transfer
applications. Automotive anti-freeze contains silicate type corrosion
inhibitors designed to be compatible with automotive components.
In an industrial application, the silicates will form a gel on the heat
transfer surface which will result in substantial reduction in cooling
capacity and is virtually impossible to remove.
