Selecting brine
When using brine, refer to the following list and select
a product that will not damage the product.
Effective freeze prevention
Will not corrode metal
Will not permeate into material
Will not generate scale
Will not damage mechanical seal of the water pump
No risk of fire
Long duration of freezing prevent effect
Effective heat exchange performance
Less toxic
Usage and precaution of brine
Drain water inside the water system and wash it
thoroughly.
Put clean water in undiluted brine, and then put
brine to rated concentration. If concentration is too
high, performance of pump may decrease due to
viscosity and proportion. The concentration of brine
is measured and maintained by a densitometer.
Be careful of leakage, and add more brine if leakage
occurred.
Brine should be maintained or exchanged periodically
(before winter time every year) considering corrosion
resistance decrease and water contamination.
Do not use brine such as ethylene glycol for hot-
water supply or food.
Check the concentration before the winter time to
prevent freezing.
Type and specification of brine
For low temperature CHILLER, use glycol type brine
such as ethylene glycol and propylene glycol. If using
other types of brine (chloride type or alcohol type),
consult with brine manufacturer and check if it is
usable. Maintain the concentration periodically by using
densitometer to prevent freezing.
Glycol type brine
Glycol type brine has less corrosiveness like alcohol
type, and also it is less explosive, flammable, and
toxic.
Chloride type brine
Chloride type brine such as calcium chloride and
magnesium chloride is corrosive to metal. If using
chloride type brine, countermeasure for corrosion
is necessary. Take appropriate countermeasure
such as adding anti-corrosive, maintaining pH and
concentration, and closing brine system.
Alcohol type brine
Alcohol type brine is less corrosive to metal but
volatile, and the vapor is explosive and flammable.
