Profile: Environmental Growth Chambers designs & manufactures plant growth chambers and controlled environment rooms. Standard sizes range from 17 cu.ft. reach-ins to 2500 sq.ft. walk-ins. In addition to our broad range of standard offerings, we specialize in custom applications to meet the unique needs of the scientific and industrial communities. We have developed a gas-tight chamber with numerous applications. The gas exchange chamber is an environmentally sealed chamber originally designed for monitoring plant performance in closed systems. The plant physiological processes that are monitored include photosynthesis, respiration, photorespiration, transpiration, translocation of photosythates & metabolites, and organic volatile emissions. We can provide a high performance environmental room to meet the most exacting specifications. With products ranging from small test chambers to 2500 ft² laboratories, and a wide range of control options, we can provide just the right environment for the work. The M series are precision research chambers, designed for optimum performance and value in the most demanding applications. They are guaranteed to provide optimum uniformity throughout the growing area, even with a full plant load. Its features include microprocessor control, aspirated sensor element modules, two phase direct expansion refrigeration system, specular interiors and barriered light caps. M series plant growth chambers come in a variety of standard sizes. Special size walk-in rooms can be designed to meet the particular requirements. We provide entomological research chambers specially designed for the propagation and study of insects. In this unique design, air is drawn across the shelves assuring uniform flow, temperature, and relative humidity on the shelves, where it is needed the most. These chambers are comprehensively engineered systems, providing precise control of a wide range of environmental climate conditions, each within close limits.
