Plasma Freezing & Blood Plasma Cold Storage

What temperature is blood plasma frozen at?

Fresh frozen plasma is typically stored at or below -18°C, and many operations hold it at -25°C or colder to extend allowable storage time. Source plasma collected for further manufacturing is commonly stored at -20°C or colder, frozen promptly after collection. The faster and more consistently a system reaches its target, the better the product is protected.

S&R evaluates freezing set points, defrost cycles, and recovery times so your freezers reach and hold those targets under real production load — not just in an empty room.

Why redundancy protects plasma inventory

A plasma facility's frozen inventory represents significant value, and an unplanned outage can put all of it at risk at once. S&R designs cold storage with redundancy so a single fault does not cascade into a loss, and sizes systems to maximize the storage you actually get out of the footprint.

We also support the operational reliability your validation process depends on, so the system that passes validation is the system that keeps running.

Walk-in freezer installation and refurbishment for plasma facilities

S&R installs walk-in coolers and freezers for blood plasma production, coordinating panels, refrigeration, electrical, and insulation into a build aligned to manufacturer specifications. For facilities running aging equipment, we handle repair, refurbishment, and replacement planning — including floor replacement and enclosure restoration — so you can extend equipment life without gambling on reliability.
