01

Start with your cooling circuit

Buying coolant starts with the equipment requirement—not the glycol name. Identify the circuit, the approved formulation and the evidence your engineering team needs. Then compare the products below with that requirement.

Equipment & cold-plate loops

Start with the equipment model and manual revision. Confirm the required fluid, water quality and wetted materials before considering a grade or concentration.

Understand the loop boundaries →

Facility & HVAC loops

Record operating and shutdown temperatures, the protection objective and the existing fill. Request formulation-specific property data for the system review.

Specify more than glycol percentage →

Immersion systems

Treat immersion as a separate fluid-selection problem. Do not infer dielectric or immersion suitability from an aqueous coolant’s purity or grade.

Turn requirements into a purchasing specification

Keep the requirement, the product evidence and the approval decision separate. These are questions to resolve—not universal acceptance limits.

Requirement	Evidence to request	Continue the review
Fluid identity & concentration	Exact formulation, inhibitor status, mass/volume basis and specification revision.	Fluid specification guide →
Thermal & hydraulic performance	Temperature-dependent density, heat capacity, viscosity and other properties required by the designer.	Sensible heat-balance tool →
Protection & water quality	Named formulation’s freeze/burst data, dilution-water requirements and equipment limits.	Protection and formulation context →
Materials & compatibility	Wetted materials, test conditions and the responsible equipment authority’s approval.	Qualification questions →

04

Grade is one part of the requirement

Technical, ACS, USP and semiconductor labels describe different product specifications. They do not independently establish cooling-loop compatibility, an approved inhibitor package or suitability for a particular equipment model.

Compare the exact product specification and formulation with your approved requirement. A shared chemical name or nominal concentration is not enough to authorize substitution. A low-conductivity aqueous fluid is not thereby an immersion dielectric.

Distinguish product references from lot evidence → · Review materials and fluid qualification →

05

Keep safety and compliance tied to the exact product

Review the current SDS for the selected formulation and the site’s approved handling and environmental procedures. Ask the responsible team to confirm applicable storage, transport, exposure-control and spent-fluid requirements for the location and use.

A grade label, a product listing or a general industry guide does not establish regulatory compliance. This page does not set reporting thresholds, disposal permissions or equipment operating limits.

06

Resolve these questions before ordering

Is this the same formulation? Do not treat identical glycol percentages as proof of interchangeability.
What does the ratio mean? Confirm mass versus volume and the conditions attached to the data.
What is already installed? Record fill and replenishment history. Ask the equipment and fluid suppliers to review any proposed change.
Which water specification applies? Compare the actual water evidence with the governing requirements; do not assume that a generic water label is sufficient.
Who authorizes release? Separate receipt of a shipment from approval to add it to the system.

Use the receiving and replenishment guide →

Frequently Asked Questions

What is the difference between Ethylene Glycol and Propylene Glycol for data centers?

They are different base fluids, not interchangeable equipment approvals. Compare the exact inhibited formulation, concentration basis, temperature-dependent properties and handling requirements with the equipment specification. A change from EG to PG requires review of the actual system.

Why is inhibited glycol preferred over plain glycol?

An inhibited formulation includes a corrosion-control package. Whether it is appropriate depends on the equipment requirements, wetted materials and operating conditions. A base-glycol purity or grade label does not establish that an inhibitor package is present or approved.

Can I use tap water to dilute my cooling chemicals?

Use only dilution water that meets the selected fluid manufacturer and equipment requirements. Deionized water is not a universal approval: compare its actual specification and handling conditions with the required water quality. Do not dilute a ready-to-use product unless the governing instructions permit it.

What happens if the electrical conductivity of my coolant is too high?

Compare the measurement with the limits, temperature and method specified for that exact fluid and circuit. Conductivity alone does not establish fluid condition or leak safety, and a low-conductivity aqueous coolant is not an immersion dielectric. Ask the responsible equipment team to interpret an out-of-range result.

How often should I check the pH of my cooling loop?

Use the equipment and fluid supplier monitoring plan for the actual installation. Record the method, sampling point, service history and applicable limits. This page does not prescribe a universal pH range or testing interval.

What is the benefit of pre-mixed glycols like Ethylene Glycol 50/50?

A premix supplies a stated formulation and concentration, reducing the need for on-site blending. Confirm whether the ratio is by mass or volume and whether the exact formulation meets your equipment requirements. A 50/50 label is not a drop-in compatibility approval.

How do I get a Certificate of Analysis?

Need the Certificate of Analysis? Just ask. Tell us the product and lot number and we will send it over at no charge. The sample COAs on our documents site show the specification format; they are not the certificate for your delivered lot.

What packaging sizes are available for large data center projects?

Check the exact product listing for current packaged sizes and request a quote for the required quantity. Confirm container construction, closure, unloading connection, delivery access and preservation requirements with the supplier; a listed container volume does not establish compatibility or cleanliness.

Is Ethylene Glycol Semiconductor Grade necessary for all systems?

No. Select the fluid specified for the exact equipment and circuit. A semiconductor grade label alone does not establish coolant suitability. Immersion systems require an equipment-qualified dielectric fluid; do not infer immersion suitability from an ethylene glycol grade.

What is the freeze protection range of your glycols?

It depends on the exact formulation, concentration basis and protection objective. Freeze protection, burst protection and acceptable operating conditions are separate questions. Review current product data and the equipment requirements instead of applying one blend’s value to another.
