Planning for Liquid Nitrogen: Integrating LN2 Infrastructure into Laboratory Design
Liquid nitrogen (LN2) is an essential utility in many pharmaceutical and biotechnology laboratories, supporting applications ranging from cryogenic sample storage and research to equipment cooling and specialized laboratory processes. Yet, LN2 is sometimes addressed only after major architectural and engineering decisions have been made.
In an article for Lab Design News, Kylie Grubb and Ivan Atencio explore strategies for planning and designing LN2 storage, siting, distribution, and safeguards. Early coordination preserves viable storage locations, efficient distribution routes, space for protective measures, and expansion opportunities, helping avoid costly change orders, redesigns, and schedule delays.
Effective planning connects storage to each point of use, addressing safety, operations, maintenance, and future needs together. Key considerations include:
- Align storage capacity and siting with laboratory needs. Match storage to demand, handling requirements, boil-off losses, delivery frequency, and reserve capacity, while accounting for structural needs, access, and life safety.
- Plan distribution piping with space and flexibility. Coordinate vacuum-jacketed piping routing, clearances, and connection points to support performance, constructability, safety, and future modifications.
- Manage LN2 risks with layered safeguards. Use applicable codes, standards, and hazard assessments to guide coordinated monitoring, ventilation, notification, and isolation measures that protect personnel from uncontrolled releases.
Early planning helps teams design safe, maintainable LN2 systems with the capacity to meet today’s demand and the flexibility to accommodate future laboratory and research needs.
