I do not know how your mechanical space is or if these are located in the same area, but if they are you may want to consider moving to a Centrifugal Chiller or Two, the kw/ton on a rotary are .75 on a centrifugal ASRAE 90.1 standard are .60. Lot's of energy savings can be achieved.
Agree...
The condensate pan is an issue but more important is the fin amount per inch and the flow of air. If you don't have those right the drain pan woill not see the water it will become airborne. If you provide me with the model and serial number of this unit I could run a selection and see if your ok.
