This is a concentrate product designed to be diluted down with distilled water before being used as a coolant. We recommend using Mayhems Ultra Pure H2O for this purpose.

Mayhems XT-1 is our thermal performance focused coolant. It is therefore recommended for use in systems where a ‘thermal performance’ product is preferred.

It combines this with the longest operational lifetime of any of our coolants.

XT-1 is based on a proprietary blend of glycols that offer a combination of excellent thermal performance, long term stability and long operational lifetime.

XT-1 also contains advanced metal corrosion inhibitors specially formulated to protect your water cooling equipment from corrosion and scale build up, prolonging your equipment life and thermal cooling efficiency.
