I was wondering if any of you would be able to help me with a problem.

For my university course I have to complete a project for an undisclosable company, where I need to design or specify a secondary refrigeration system.

The primary system which needs to be cooled has a working fluid of demineralised water at 45 deg C, this demineralised water then needs to be cooled to 30 deg C.

I was wondering if there was an off the shelf self contained refrigeration solution to this problem, instead of having to design and specify each individual part of the new system myself.

Any help would be much appreciated.
