Anodizing & Plating Chiller Technical Support-
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 Anodizing industry chillers are in a very caustic environment. This is because of the many different acids and etches that are used to do the metal plating. The chillers age faster than most especially on the air cooled condensers. Keeping them clean is very important.
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. Anodizing chillers run through coils to cool the acid baths where heat is created. Some have modulating valves to not over-cool the acid baths. Be sure to have a water bypass so that pumps do not “deadhead” and overheat and fail.
