So I had a dilemma, I live in aridzona, and I previously had a HY watercooled spindle that did me proud. I wanted to use the redline VFD, and yes it runs the HY 2.2KW watercooled spindle flawlessly, no issues. I did see that Redline is now offering a watercooled spindle option, but this hybrid works for me, and so if mine ever peters out, I’ll just get that spindle. I paired this with finally a good watercooler so my spindle is nice and cool and no more ice baths for my ugly water tank.
Just a heads up if you have the odd situation like me.
