Inhibited Deionized Water, Glycol-Free is a ready-to-use deionized water coolant for indoor liquid-cooling loops. It is high-purity DI water pre-blended with 1.8-2.2 % of a nitrite-free closed-loop corrosion inhibitor (Formula 1500OP, sodium benzoate based), with zero glycol and no biocide. Fill it straight into data-center cold plates and CDUs, lab chillers, thermal test rigs and other closed loops that never see freezing temperatures. It ships from Taylor, Texas, in sizes from a 1-quart bottle to a 330-gallon IBC tote.

Why not plain deionized water?

Plain deionized or distilled water carries heat well but gives the metal in a loop no protection. In service it picks up carbon dioxide and oxygen and slowly attacks steel and copper, and the corrosion products foul cold plates and raise conductivity. This liquid cooling coolant adds a nitrite-free corrosion inhibitor to the same high-purity water, so you get the heat transfer of water with closed-loop corrosion protection, and nothing to mix on site.

Glycol-free vs PG/EG coolant: when to use which

  • Use glycol-free inhibited water when the whole loop is indoors and above freezing (data-center halls, labs, test rigs). Water carries more heat than any water-glycol mix and flows more easily.
  • Use an inhibited glycol coolant when any part of the loop can freeze, for example outdoor dry coolers. See Inhibited PG 25/75 or Inhibited EG 40/60, Nitrite-Free.
  • Use plain Deionized Water only if you add your own inhibitor package.

Where it is used

  • Data centers: direct-to-chip cold-plate loops and CDU secondary loops inside the white space
  • Labs and universities: recirculating chillers, thermal test systems and research cooling loops
  • Industrial process cooling: closed-loop equipment cooling indoors
  • Custom PC and workstation water cooling: closed indoor loops where you want water, not glycol

Sizes

  • 1 quart and 1 gallon: top-offs, bench tests and small loops
  • 5-gallon pails: test rigs and lab chillers (8 pails is about 150 L)
  • 15- and 55-gallon drums: small and mid-size loop fills
  • 275- and 330-gallon IBC totes: initial fills and bulk charging

Frequently Asked Questions About Inhibited Deionized Water, Glycol-Free — Data Center Coolant

What is Inhibited Deionized Water, Glycol-Free?
A ready-to-use liquid-cooling fluid: deionized water with 1.8-2.2 % by weight of Formula 1500OP, a nitrite-free closed-loop corrosion inhibitor based on sodium benzoate. It contains no glycol and no biocide.
Can you use deionized water as a coolant?
Yes, in a closed loop that never freezes, but not plain. Plain deionized or distilled water has no corrosion protection: it picks up carbon dioxide and oxygen and slowly attacks steel and copper. Inhibited Deionized Water, Glycol-Free is DI water pre-blended with a nitrite-free corrosion inhibitor, so it can go straight into the loop.
When should I use a glycol-free coolant instead of a PG or EG coolant?
When every part of the loop stays indoors above freezing. Water carries more heat per litre than any water-glycol mix and is thinner, so the same pump moves heat more easily. If any part of the loop can see freezing temperatures, use an inhibited propylene glycol (for example PG 25/75) or ethylene glycol coolant instead.
Distilled or deionized water: which is better for a cooling loop?
Both are low in minerals. Deionized water is purified by ion exchange and typically reaches lower conductivity than distilled water. Either one still needs a corrosion inhibitor in a closed metal loop, which is why this product is DI water with the inhibitor already added.
Can I use it in a custom PC water-cooling loop?
Yes, it suits closed indoor loops, including PC and workstation water cooling, and comes in 1-quart and 1-gallon sizes. It has no dye and no biocide, and the finished fluid has not been coupon-tested, so check your component maker's coolant guidance first.
Does it give any freeze protection?
No. It freezes at about 0 °C (32 °F), like water. It is for indoor loops only.
Does it contain a biocide?
No. It contains no biocide. If your system specification calls for one, it has to be added separately.
Is it nitrite-free?
Yes. The inhibitor is a sodium benzoate package with phosphate only as a trace (under 0.003 % of the finished fluid). It contains no nitrite and no glycol.
Is it compatible with aluminum or copper cold plates?
The finished fluid has not been coupon-tested, so check it against your equipment maker's coolant specification before filling a loop.
Is it hazardous or regulated for shipping?
No. It is not regulated for transport by DOT and is not classified as hazardous under OSHA HCS / GHS. The SDS and TDS are on docs.alliancechemical.com.
What sizes do you sell?
From 1 quart to a 330-gallon IBC tote. For example, a 150 L test loop takes 8 x 5-gallon pails (40 gallons).
