Operation
Basin heaters systems will not prevent the coil from freezing.
Unless some means of freeze prevention is incorporated into your system, the tower basin and exposed pipework should be drained at the beginning of each wintertime shutdown period.
If fluid cooler basin is drained, verify that all basin heaters have been shut off either by automatic cutoff or disconnect switch.
Protection Against Coil Freezing:
Ethylene and propylene glycol solutions are the best means to protect the coil from freezing. The following table provides the coil volume for each MC Fluid Cooler model. When the use of industrial antifreeze solutions is not possible, the system must be operated to meet both of the following conditions.
1.Maintain sufficient flow rate through the coil.
2.Maintain sufficient heat load on the process fluid. Fluid exiting the coil must be maintained at or above 8°C. Cycling of the recirculation pump should not be used to control process temperatures.

Draining the coil is not acceptable as a normal method of freeze
It is recommended that you discuss your freeze prevention options with your local Marley sales representative.
