Vacuum Coating 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 Vacuum Coating industry chillers generally are located outside if there is a large facility or portable ones indoors.  Either way, the flow rates and pressure are important because even the smallest stop in flow will stop the vacuum coating machines. If this occurs an entire day of production can be lost.

5.  Be sure that your chiller, if air cooled and inside, 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.  

6. Vacuum Coating chillers generally have very clean water because they have to go through the tooling of the specially designed vacuum chambers.  Clean water is a must or the tooling will get clogged.  Be sure to clean Y strainers often and have bag filters in place.
