Environmental Rooms, Test Rooms

  • Environmental Rooms, Humidity Rooms, Stability Rooms

    Russells environmental rooms incorporate modular designed prefabricated panels for an economical solution for steady state testing. We have incorporated many years of designing custom industrial test systems and have incorporated the latest technologies into this product.

    We’ll provide a turnkey installation of your room with equipment designed to meet your exact needs. Our rooms are engineered to handle your steady state temperature and humidity requirements.

    Since 1972, Russells has utilized its expertise in refrigeration and air conditioning technologies to manufacture environmental rooms which can maintain -40° F cold on a continuous basis or chambers which can reach as high as 185° F heat. These simulation test systems can be supplied with temperature and humidity PID controls or with computerized data acquisition and control systems. They allow customers to undertake long-term stability testing, accelerated testing, humidity testing, comparative stability testing, forced long-term stability testing and stability of active pharmaceutical ingredients. Our environmental rooms are designed to meet FDA and ICH guidelines for stability testing and storage. They’re installed in facilities around the world where technicians can reach-in, walk-in or even drive-in to conduct a wide variety of simulation testing. We use the highest quality components in fabrication to ensure that our environmental rooms continue at top performance for many years.

    A Russells application engineer can assist you in selecting the environmental room configuration and size that’s best for you or we can custom design from our standard configurations.
