I have a customer with 2 30RB and 2 30XA chillers that go thru heater pads continuosly. The 30RB chillers have 2 bundle heater pads per machine that have all been replaced at least twice in 3 years.
The 30XA oil seperator pads also have been changes multiple times. When looking at failed ones they typically have burn marks where it looks like they shorted against the barrel.
I suspect moisture causes these failures and am trying to come up with alternative solutions as these are high dollar pads and the cust is very frustrated.
Carrier insists they replace very few but the number of failures on these 4 machines makes me think there must be another option.
Has anybody else had this experience. Thanks
