Chemical Chiller Technical Support-
Simple checks before you call.

  1. The first thing to check with your chiller and all chillers that are not working is to note what displays are listed on the main panel or note what the visual gauges show to you.  Do this before you reset anything.  This is the most valuable information for any service technician when you talk to them.

2. The chiller may not work because the incoming voltage is not correct or missing a phase.  Brownouts can cause poor incoming voltage or a dropped leg.  Check all fuses and incoming voltages to be sure that the main power is correct.

3. Confirm that the chiller tank is full and pump is circulating.  No chiller should run if the pump is not running first.  Flow related issues can occur.  Another issue to check would be any Y strainers or filters that slow or stop the flow when blocked with debris.

4. The Chemical industry chillers generally cool heat exchangers or jacketed vessels and do not come in contact direct contact with the chemical product itself. Its important to make sure that fluid is flowing through these exchangers and that they are not clogged.  

5.  Be sure that your chiller, if air cooled, can breathe and the area where it runs is not over 100F.  Most portable indoor chillers are not rated for overly high inlet air temperatures.  Outdoor chillers can handle the higher inlet air temperatures but need to be clean.

6. Chemical chillers can be dual purpose (both heating and cooling).  Be sure that the venting of hot or col water is not being lost down the drain during switchovers.  This can cause low flow and alarms due to low water levels.
