The Tenney Environmental is an environmental test chamber line. The Tenney Environmental is used for temperature, humidity, altitude, vacuum, and related environmental testing. The Tenney Environmental includes walk-in chamber configurations.[1][2][3]
One Tenney walk-in environmental chamber provides a large interior volume of 234 cubic feet, with dimensions of 72 inches wide by 72 inches deep by 78 inches tall. The chamber is designed for testing equipment under simulated environmental conditions.[3]
The Tenney walk-in chamber is cooled by a two-stage refrigeration system and heated by electric resistance heaters. Platinum resistance thermometers and a Vaisala humidity sensor measure temperature and humidity. A VersaTenn V microprocessor control system with a proportional–integral–derivative (PID) algorithm manages temperature and humidity automatically. The system includes an internal log function that continuously records conditions and allows the user to preprogram temperature and humidity profiles. The chamber can also perform liquid, freezing, and precipitation tests.[3]
Tenney environmental chambers are used across a broad range of industries including aerospace, defense, automotive, medical, pharmaceutical, electronics, energy, and telecommunications. Typical applications include safety testing of lithium-ion batteries, stability and shelf-life testing of sensitive electronics and pharmaceuticals, and thermal-shock testing of military components.[2][1]
