Hi,
can me somebody help:
We want to do retrofit on two cooling chillers with axial fans, 30 kw and 200 kw. Now works with R-22.
With which refrigerant we must do retrofit ? Which spare parts must we replace on chillers when we do retrofit?
Thank you for quick reply
Best regards

Re: retrofit
Why retrofit? If they run, let them run.

Re: retrofit
That are retrofitting refrigerant. You could also use DROP IN refrigerants.
