Large Temperature & Humidity Chamber (FD Series)
These large format temperature & humidity chambers cater to heavy loads and large assemblies such as EV battery packs, drivetrains, dashboards, and motor assemblies. In addition the are popular with large avionics assemblies and aerospace systems before deployment to space. With a wide temperature range and huge load capacity they’re ideal for the biggest pieces of the puzzle.
Standards such as MIL, ISO, IEC, and LV 124 are all attainable with the FD series with configurations built to your specifications. Additional options are available including solar radiation, corrosive atmosphere and altitude combined with temperature.
