RH Temperature Stability Chamber
RH Temperature Stability Chamber acrylic cabinet is customized for storage of polycarbonate films used for high-precision screening of circuit boards. It maintains critical relative humidity and temperature levels to prevent dimensional aberrations that result from exposure to humidity and temperature fluctuations. Air circulates horizontally across the shelves that hold the film. As air exits the storage area, it passes through an air conditioning/heating module that conditions it to within ±2°F (-18.9°C to -16.7°C) of the temperature set point. In addition, the continuously operating A/C module removes moisture to keep the %RH level within ±3% of the set point. If humidity falls too low, an ultrasonic humidifier cycles on to add the proper amount of water vapor. If the temperature falls too low, the heater module cycles on. A water filtration system removes contaminants from the humidification feed water to eliminate the chance of mineral deposits or other vapor-borne contaminants.
