As far as Koolant Koolers go, my experience has been great. I have had the opportunity to meet the Engineering Team at Koolant Koolers and was impressed with the depth in thermodynamics and heat transfer knowledge. Since the systems were installed, I haven't had any troubles. Koolant Koolers seemed to dial everything in at the initial system startup.
