Laser 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.  This is unlikely because water used in a laser chiller is usually DI water and they have their own DI water filter system to add as needed.

4. The Laser cutting industry chillers can also use “Water cooled” chillers.  These chillers do not have fans and have a separate water source from a cooling tower or the like.  If this water source is not flowing the chiller will not work.  Check cooling tower for high temps and flow.

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. Laser cutting chillers have two zones (Optics and laser) each one needs a different flow, pressure and temperature.  If the temperatures vary too much the modulating valves could have failed.
