OK sorry for the very newbie and perhaps rediculous suggestion of wanting to use a regeration system to cool water in a tank.

The tank holds approx 20 litres of water ...

The problem comes from the fact that the water can reach tempratures of I would guess 40-50deg C.... from time to time.

The idea I had is getting a Danfoss DB35 compressor unit and fit a fin evaporator submerged in the fluid (the tank will have a internal pump to stir the fluid)....

The system has the following spec

Cooling capacity (max w/ normal refrig. w/ direct evaporator) (l) 250
Cooling capacity (max. deep-freezing) (l) 70

Question is will this work given the potentially high temp the fluid can reach?

Can I imerse the evaporator?

Does this compromise the efficiency?

How long would the system take to get the fluid to sat 10degc from 50degc?

Any other suggestions?

Thanks in advance and please indulge my ignorance here!
