Drying chamber type “H-Dry”, type “K-Dry” and type “U-Dry”
The conventional drying chamber or the “H-Dry” drying cabinet or laboratory drying cabinet variant works according to the standard principle.
K-Dry is a drying cabinet for relatively high humidity with moderate temperature and energy requirements. The K-Dry is used for drying dripping wet parts. The “K-Dry” has a drying air generator, but works with a cold trap and heat pump, so that a lot of water can be separated in an energy-saving way and at the lowest moisture level.
We have optimised this type in the segment between conventional drying chamber and ultra-dryer and thus created an ideal all-round drying chamber. This is because conventional drying chambers require a minimum temperature and can remove large amounts of moisture. Ultra-drying chambers operate almost at room temperature and allow a low humidity level at a dew point of around -20 degrees Celsius. In the intermediate range at high humidity and low temperature, the “K-Dry” has now been developed. It reaches a dew point of around 0 degrees Celsius and can thus be used at moderate drying temperatures and high humidity levels.
The warm exhaust air from the drying air generator is used to preheat the supply air to the drying cabinet. This heat recovery results in energy savings of more than 50% for the entire system.
The “U-Dry” is one of the ultra-drying chambers and produces a minimum moisture level with moderate temperature and energy requirements: Ultra-drying chambers or ultra-drying ovens work independently of the ambient air and its humidity. That is why the “U-Dry” is the right choice for high-quality drying of electronic components (IPC / JEDEC 033 A) and high-quality plastics that are not suitable for a hot-air dryer.
The drying cabinet works like a granulate dryer with a drying air generator: it can be used for material-friendly and energy-saving drying regardless of the season and the corresponding air humidity.
