Bahnson Environmental Specialties is now Environmental Specialties, LLC.

Cold Rooms

A stable cold room environment is necessary for most types of product storage. Minute fluctuations in temperature and humidity can adversely affect product viability, making properly designed cold rooms critically important.

Environmental Specialties has extensive experience designing and installing cold rooms with single-point or variable set-point temperature control, volumetric uniformity, and advanced dehumidification equipment to help maintain precise relative humidity (RH).

Our cold rooms are suitable for a wide range of storage applications in a variety of industries, including:

  • Bulk raw material and finished product
  • Media, chemical, and reagent holding
  • Depressed temperature stability and shelf-life studies
  • Hazardous material
  • Vaccines and drug product
  • Chromatography and analytical separations
  • Plasma and blood product

REQUEST QUOTE

  • “Thanks again for the support in getting us to this stage eventually – finding an incubator that meets our temperature spec has been a challenge for us for the last few years and this is a significant milestone for the business. Hopefully we will have more good news to report in the new year.”

    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.”
