Dehumidifier questions

[m0tion]

Is there any problem with running -40C liquid through a regular Eheim 1250? Anything special that need to be done to it? Will it shorten the life-span?

Also, is a 15-pint dehumidifier strong enough to run a chilled water system with?

i would check the pumps specs
they do list what temps the pumps do/can operate at....
but i dont think your average pump will work at -40C
