Stability Rooms

Stability chambers and stability rooms are temperature- and humidity-controlled environmental units that provide stable conditions for storage and testing purposes.

These specialized environmental chambers, which can exceed 5,000 square feet and are designed for specific loading conditions, provide a precise, elevated temperature and/or humidity to determine if there is long-term, intermediate, or accelerated degradation of a product or its packaging over time.

Environmental Specialties stability rooms are suited for a number of walk-in test chamber uses, including:

• Long term stability studies
• Accelerated stability studies
• Freeze / thaw and thermal cycling
• Extended range testing
• Packaging studies

Standard Features

• Modular metal skinned panels with urethane insulated tongue and groove construction for chamber enclosure
• “Cam-locking” construction with vinyl gasketed seams fitted on the interior and exterior of each panel to provide moisture and vapor-tight seal
• Internal low height stainless steel or aluminum ceiling plenum housing to include low wall return for efficient even air distribution throughout the space
• Totally accessible hinged drain pan for maintenance and cleaning of all interior plenum components from within the space
• ECM fan motors for energy efficiency, which are rated for operating temperatures and remoted from chamber interior when necessary
• Semi-hermetic compressors continually operating for extended equipment life and increased temperature & humidity control & uniformity
• Uniform air distribution via a pressurized plenum space through a lay-in perforated ceiling air distribution system with anodized aluminum T-bar grid support
• Fully accessible control panel to efficiently and securely house all controls, alarms, and recording devices
• Conformance to FDA 21 CFR11 requirements for data recording, audit trails of controller settings modification, alarm history logs, operator event logs and secure file transfers
• Touchscreen system control of chamber parameters to include intuitive control screens and menus, easily programmed process alarms, and highly configurable circuit switching with 0.1ºC resolution for temperature and 0.1% resolution for RH
• Control Panel certification built to MET, UL 508A
• Electrical wiring to National Electric Code (NEC)
• Vapor proof & energy efficient LED light fixtures
• Factory leak testing standards: Helium mass spectrometer to 1E-5, Nitrogen leak testing unit coolers to 300 pounds, condensing units to 175 pounds, evacuations minimum 200 microns
• QA/QC bench testing of complete control panel and electrical devices prior to shipment
