Chiller Replacement is a Tight Fit

IMG_1908

We recently were asked to replace a 10 ton chiller unit (air to water) that was rusting away in the salt air.  Our concern was that the failure of the chiller’s case would lead to fractured refrigerant or chilled water lines which would result in a total loss of cooling for the residence.  The entire base pan of the unit had rotted away so we carefully drained the water, evacuated the refrigerant from both 5 ton compressor circuits, and cut the unit up so that we could remove it.

We knew that the new unit would be a very tight fit through the existing garden gate.  The new unit was also 1,100 pounds so it would be challenging to move.  Here the skilled delivery by Cape Cod Express positions the new chiller on a sheet of plywood.  The new chiller is still bolted to its pallet.

We followed the efforts of the pyramid builders in Ancient Egypt and lay out over 20 short rollers made of 1-1/2″ PVC pipe.  We then unbolted the chiller from the pallet and very carefully slid it through the garden gate. We had 1/2″ clearance on either side.

The chiller slid very nicely on the 1-1/2″ PVC pipe and we were able to carefully slide it around the support posts into position on the existing pad.  Thank you Ancient Egypt for the roller concept!
