Supplier Qualification Packet
One zipped download containing the TDS, SDS, latest lot COA (when available), and a fresh Letter of Continuing Guaranty for Inhibited Propylene Glycol 25/75 with OAT Inhibitor — Data Center Coolant. Every file included is SHA-256 hashed and listed in a manifest your QA team can audit.
Application Guidance
Inhibited Propylene Glycol 25/75 with OAT Inhibitor — Data Center Coolant is a glycol-based heat-transfer and freeze-protection fluid. Concentration sets the freeze and burst protection; the inhibitor package sets how long the system stays protected from corrosion.
- Closed-loop heat transfer and process cooling
- Data-centre and chilled-water freeze protection
- HVAC hydronic loops and glycol makeup
- Freeze and burst protection for idle or seasonal systems
必要な凍結・破裂防止性能に対して濃度を確認し、使用温度におけるエラストマーおよび金属材料との適合性を確認してください。食品または飲料水への偶発的な接触が起こり得る用途には、USPグレードまたは食品グレードのプロピレングリコールのみが適しています。インヒビター入りグレードは密閉系の熱媒体用途専用です。
Storage & Handling
- Recommended Storage
- Cool, dry, well-ventilated area in tightly sealed original containers. Neat glycols are combustible liquids with high flash points (roughly 99–111 °C) and do not require a solvent store; aqueous blends will not sustain combustion. Protect inhibited coolants from contamination and from freezing below their stated protection point.Class-level guidance — not product-specific; the SDS controls.
- Handling Precautions
- 耐薬品性手袋および飛沫防護ゴーグルを着用してください。高温の表面や高温のプロセス機器との接触を避けてください。インヒビターは使用中に消耗します。やみくもに補充せず、監視してください。Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizers, strong acids and strong bases. Galvanized (zinc) surfaces are attacked by many inhibited coolant packages. Verify elastomer and gasket compatibility for the service temperature; EPDM is standard for glycol/water service.Class-level guidance — not product-specific; the SDS controls.
- Shelf Life
- Consult Technical Services for product-specific shelf life
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
