I am repairing a cascade tuned to hold 225 watts at -78c using r23 in second and using 1/2hp compressors on both the first and second. The customer needs the unit to hold 350 watts possibly even 400 watts. Im going to need to upgrade both those compressors right?
Sorry if this is a silly question but I have never used small compressors in a 2 stage before.
