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 50/50 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 50/50 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
