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 45°F. 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
protection—draining promotes corrosion inside the coil tubes. Drain-
ing is acceptable in an emergency if the coil is not protected by an
antifreeze solution.
It is recommended that you discuss your freeze prevention options with
your local Marley sales representative.
