  • TypeCPU Block

  • Safe on acrylic, rubber and all gasket materials
  • Two-year shelf life when kept sealed

Pure coolant foundation

PrimoChill Base High Purity Deionized Water arrives as a clean, 128oz starting point for custom liquid-cooling loops. The multi-filtered, polished water contains no inhibitors, dyes or antimicrobial agents. It is safe for acrylic, rubber and common gasket materials. The bottle provides a blank canvas for DIY builders who prefer to dose their own additive package.

For DIY loop builders

This product suits enthusiasts who want full control over corrosion protection, biocide strength and colour. It is not for users who need a ready-to-pour fluid with pre-mixed inhibitors. Builders lacking separate antimicrobial or corrosion-inhibitor supplies should look elsewhere. The fluid also does not address thermal-conductivity additives or specialised surfactants.

One-gallon capacity headroom

The 128oz volume fills most single-loop configurations with enough reserve for a flush and top-off. Large multi-radiator builds or dual-loop systems may require additional bottles. Once opened, the two-year shelf life applies only to the sealed container; plan additive dosing and loop assembly promptly to avoid contamination.

Questions about this item

What cooling components must already be in my loop before I add this 128oz deionized water?

You need a pump, reservoir, radiator, water blocks and tubing already installed; this fluid is the coolant that fills the completed loop.

Will this water work safely with the acrylic reservoirs and rubber gaskets I already use?

Yes, the fluid is safe on all plastics, rubbers and gasket materials including acrylic, so existing components can stay in place.

How can I confirm the loop is running correctly after I fill it with this water?

Power the pump, watch for steady flow through the reservoir, check that temperatures stabilise and inspect every fitting for leaks.
