Bahnson Environmental Specialties is now Environmental Specialties, LLC.

Clean Cold Rooms

Clean cold rooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporized particles, while maintaining temperature and relative humidity (RH) set points. They are often used for specialized production or scientific research, and manufacturing.

Our skilled engineers are ready to meet the demands of customers seeking high-quality cold, clean environments, including those meeting ISO 5, 6, 7, and 8 regulations. Our clean cold rooms are suitable for a wide range of applications including:

  • Testing
  • Production
  • Sanitary processes
  • Hazardous materials

Versatile Clean Cold Room Design

Our clean cold rooms combine maximum flexibility with advanced reliability features, providing precise control over temperature and RH in a pristine environment.

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.”
