Freeze protection of ethylene glycol solutions
Glycol systems require specific inhibitors compatible with the materials of construction they come into
contact with. These inhibitors generally come pre-mixed with the glycol additive for the cooling circuit.
Ice due to subfreezing ambients

tanks that have been exposed to severe or sustained subfreezing ambient temperatures, should be
checked before initiating an ice build cycle. Ice created by subfreezing ambient temperatures which accumulates
at the top of the tank and around the walls must be melted out before initiating a build cycle. This ice can prevent
normal water displacement during the build cycle, possibly leading to physical damage to the coil and tank walls.
Ice melt can be confirmed visually, but it is recommended the temperature of the water in the tank be raised to
4,4°C to ensure all ice is melted.
