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 MH
Fluid Cooler model. MHF7111 and MHF7113 coil volumes are for both coils
added together.

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 7°C. Cycling of the recirculation pump
should not be used to control process temperatures.
