Mayhem XT-1 Coolant is a High Efficiency, Non-Toxic, Low Viscosity coolant based on Ethylene Glycol. This is our first foray into Glycol cooling and comes as a concentrate that needs to be mixed with water to create a premix. Only a small amount is needed per system and Mayhems XT-1 has the ability to be used with water chillers down to a staggering -50c (dependant on mixing ratios).

Once opened Mayhems XT-1 will only be useable for up to 3 years. Keep in a dark, cool, dry place else the life time of the concentrate will be reduced.



  • More efficient heat transfer then vegetable extract
  • Easier to pump, especially at low temperatures.
  • Less volume for the same freeze protection.
  • Has been tested and classified as Non-Toxic by an EPA certified laboratory.
  • Additive has very little effect on heat transfer or antifreeze performance.
  • Readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.
  • Synergistic corrosion inhibitors to protect metals commonly found in such systems that contain mild & stainless steel, aluminium, copper, brass and cast iron and plated products.
  • Contains scale and biological inhibitors to help prevent fouling – thus promoting long operational life and high thermal efficiency.
  • Exhibits super-cooling characteristics and mixtures containing in excess of 50% by volume and they do not freeze solid.
  • Safe to use with Mayhems Dyes
  • Child Safty Cap fitted as standard
