Freezer Chambers

Our freezer reach-in chambers offer exceptional volumetric temperature uniformity and a versatile array of features and capabilities. They are designed to store materials at temperatures as low as -25°C, but are also flexible enough to operate at warmer temperatures when required.

To reduce frost build up, we equip our freezer reach-ins with an automatic defrost cycle. For additional protection, we offer an optional dehumidification system that can help keep them entirely frost free.

Our freezer reach-ins are suitable for a wide range of storage applications in a variety of industries, including:

  • Accelerated stability assessment programs
  • Chromatography and analytical separations
  • Media, chemical, and reagent holding
  • Frozen temperature stability and shelf-life studies
  • Extended range testing
  • Package studies
  • Drug research
  • Biomedical, vaccine, and sample storage

    Project Engineer, Major Biotechnology Manufacturer

  • “During a recent external audit, an inspector requested the PM/Cal documents for the stability chambers. It was my pleasure to give him the nicely presented binders. I could tell he was impressed.

    Thanks for the great service you have provided for us over the years.”

    Teresa P, Taste Texture and Health, DSM-Firmenich

  • “Environmental Specialties has always provided me with great service. All the individuals I worked with were knowledgeable about ES products and services.  They were highly skilled. I relied on ES for pm, calibration, qualification, repair, chamber sourcing and consultations. I interacted with a lot of your employees.  The feedback was always spot on. They were always smiling and supportive even in the most difficult situations. ES is a great company with good people.”
