Tenney TC Series Cycling Test Chambers

The TC Series of environmental cycling reach-in test chambers include both temperature-only chambers and temperature / humidity chambers. The Tenney TC Series Cycling Test Chambers offer design features for optimal performance such as a high volume horizontal-down air circulation system with an electric heating system and a mechanical refrigeration system. If the humidity option is selected, a vapor injection type humidification system is used to condition the product. A wide range of options can be added to enhance the equipment. Since 1932, Tenney engineering continues to incorporate the latest technologies in heating, cooling, and humidification to meet the most stringent demands in the industry.
