Printing 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 Printing chiller tank is full and pumps are 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 Printing industry chillers have different fluids for different areas.  Some are just water, some are glycol and others are dampening solutions that keep the inks from sticking.  Be sure that these fluids are clean and well maintained.

5.  Most Printing press chillers are split system units to keep the blowing hot air away from the printing presses.  This air movement can ruin the finished product.  Be sure to clean the remote condensers especially during the hot season.

6. Printing chillers are very elaborate because they have multiple zones with different temperatures.  If one area is overheating, check the modulating valves in case one has failed to open and cool the area needed.
