SDR custom size desiccant drying and storage rooms control and trace moisture sensitive components, boards and assemblies. Modular enclosures accommodate feeder trolleys, WIP carts and PCB racks. Employ energy-efficient, dual wall insulated steel construction; enable rapid, oxidation-free drying at 40°-60°C and safe storage per J-STD-033C. U5000 Series Dry Unit is said to deliver 0.5% RH and closed-loop regeneration that responds to the atmosphere in the cabinet. Relevant process data are obtained with use of a 0.8% digital sensor. Data can be logged directly through RS232 with available software links.
