Walk-in Deep Freezer

The Pharmaceutical & allied industries use Deep freezers for effective storage of drug products, life-saving vaccines and samples for diagnosis, but are also perfectly suited for temperature tests and aging subjected at sub-zero temperatures.

They can be used for storage of fresh and frozen blood supplies and vaccines, also for storage of enzymes for research.

Allyone Walk-In Deep freezers are available with “Ante Chamber” as a barrier between Ambient & Sub Zero, so as to cool down the samples from ambient temp to near zero, then shift them in the Deep Freezer so as to make the process more efficient & economical for your need for a precision-controlled storage equipment as low as -30°C. Allyone deep freezers have great safety features and are trustworthy & reliable.
