Base for custom coolant loops

PrimoChill Base High Purity Deionized Water is a neutral foundation for DIY liquid-cooling builds. It contains no inhibitors or biocides, so you control the exact additive package. The fluid is safe for acrylic, rubber and common gasket materials.

32 fluid ounce bottle

Each container holds 32 fluid ounces of multi-filtered, polished water. The deionised liquid arrives ready for dyes, corrosion inhibitors or antimicrobial agents that you source separately. Unopened bottles carry a two-year shelf life.

Low conductivity and non-corrosive

The high-purity water minimises electrical conductivity and will not attack loop components under normal temperatures. Pump noise and thermal performance depend on the additives you introduce. No heat is generated by the fluid itself.

Questions about this item

How much coolant will a 32 fl oz bottle fill in a typical custom loop?

A 32 fl oz bottle provides roughly one litre of fluid, which is usually enough to fill a standard CPU and GPU loop with a single radiator and reservoir.

Does this deionized water contain any corrosion inhibitors or biocides?

No, it is a pure base fluid without any inhibiting ingredients, so you must add your own corrosion inhibitors and biocides before use.

Is the fluid safe for acrylic reservoirs and rubber gaskets in the loop?

Yes, the fluid is safe on all plastics, rubbers and gasket materials, including acrylic components.
