Thermal Spray Chiller
Simple checks before you call.
- 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 Thermal Spray industry chillers have very hot areas to cool and the Thermal Spray machines have alerts for water flow and pressure before they can start and run. Be sure there is good flow and pressure if you are getting machine alarms.
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. Thermal Spray chillers generally have 2 separate pumps. One for just the chiller and another (higher pressure pump) for the cooling of the nozzles. Be sure that both pumps are running. You could have the chiller pump running and the fluid cool but not going to the nozzles.
