Environmental Rooms are ideal for steady state temperature & humidity testing, stability & shelf life testing, cold room labs and incubation. These can be designed to include heating, refrigeration, humidification, dehumidification, and lighting to accommodate a variety of applications. Flexible, interlocking panelized construction can easily accommodate any arrangement and a variety of heights. The strong, lightweight panels provide optimum insulation. The located control panel allows easy monitoring of all room functions, while state-of-the-art controls provide precise regulation of the simulated environment. Tongue-and-groove panel incorporates an inherent thermal break that eliminates the possibility of metal-to-metal transfer of heat from the interior to the exterior. Cam lock fasteners draw opposing panels tightly together for an impenetrable seal and permit quick assembly.
