Java_avaJ ACS don’t do the powder coat in house, that sounds like a bad thing perhaps? However good a paint coat is it’s a coat of paint and on a metal that must expand and contract with the heat it’s surely bound to crack and peel after a year or two - anyone got any experience of that?
ACS will do what they do well, but They leave the powder coating to expert powder coaters…They Leave main board firmware programming to Gicar, the board manufacturers. Case laser cuttiing and, polishing to the sheet metal company.
e.g. You may not know but ACS make their own refrigeration systems for slushie machines etc.., seal them, use special copper tube as well, very smooth and clean inside, higher grade than standard stuff. That’s the same tubing in your machines. Probably doesn’t make any difference (meant to corrode less), but that’s the tube they have in stock.
I’m not an expert on powder coat, but it’s a slightly flexible coating, so shouldn’t crack or peel. They did have a few problems a long time ago at first when they didn’t powder coat directly onto stainless, but that was changed pretty quickly, they learn their lesson. Allow wheels on Cars are powder coated and they stand up remarkably well considering the very harsh environment they are in.
