Product Description
Drying chambers are used whenever a particularly low level of humidity is required, whether it is for storing food or dehumidifying test objects. Alongside drying and storage, modern drying chambers also enable more complex applications, such as simulating aging processes and carrying out general material testing.
Whereas conventional units generally only allow you to adjust the temperature - in a similar way to a traditional electric oven - drying chambers also offer active humidity regulation. This makes it possible, for example, to dehumidify objects even at an ambient temperature of +5°C, which is a crucial advantage in the case of electronic components in particular.
The temperature range of drying chambers is therefore generally between an ambient temperature of +5°C as the lower limit and around 300°C as the upper limit. In fact, there are already units which can go beyond that and enable temperatures below 0°C.
The sizes of drying chambers vary significantly between applications. The smallest units hold around 30 liters while the largest can hold several hundred liters. For even larger applications, for example in the field of vehicle construction, facilities known as dry rooms are used.
Product Parameters
Whether they are employed in quality assurance, industrial applications, or scientific laboratories, thermal processes often make use of a drying chamber. As it is usually operated on a daily basis, it is vital that the unit is reliable in order to guarantee high quality standards and process stability.
Drying chambers can be used in a variety of different applications. You can find them in all drying or sterilization tasks, including curing, tempering, heating, burning in, and even long-term heating. They are also used in temperature stress tests or accelerated aging tests as part of material testing processes. In order to ensure the best drying results, completely homogeneous temperature distribution is crucial. A drying chamber must be suitable for a wide range of tasks and easy to integrate into the relevant test processes without any problems.

Types
1. Drying chamber type "H-Dry": conventional, but efficient
The conventional drying chamber or the "H-Dry" drying cabinet or laboratory drying cabinet variant works according to the standard principle:
Ambient air is drawn in, heated and fed into the drying chamber so that the product moisture can be absorbed and removed via the exhaust air. This is inexpensive to purchase, but often somewhat more demanding in terms of energy consumption. H-Dry is therefore energy-optimised and offers high performance with manageable energy requirements.
2. K-Dry drying cabinet: for high requirements and lower energy consumption
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.
3. Drying cabinet type "U-Dry": gentle drying with drying air
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 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.
FAQ
1. What are the applicable guidelines when working with drying chambers?
When buying your drying chamber, the most important thing to bear in mind is the recovery time after the door is opened. This is governed by a specific standard in the context of standardized material testing.
In order to check the reference values, the door of the drying chamber is opened for 30 seconds at the highest test temperature once the steady state has been reached. The temperature is then measured in the center of the usable space until it falls to the corresponding value. The time it takes to reach the specified limit deviation is determined.
Determining heating up time and cooling down time
When purchasing your drying chamber, pay attention to the technical data and manufacturer information regarding temperature homogeneity and temperature stability.

2. What else should you bear in mind when choosing your drying chamber?
In the majority of applications, from industrial use to medical research, the drying chamber is in operation every day, virtually round the clock. The unit therefore needs to be highly reliable. A small number of manufacturers have proven themselves over the long term in practical applications. The more demanding your application, the more you need to prioritize quality when it comes to buying your drying chamber.
In the case of temperature and aging tests in particular, homogeneous temperature distribution is of paramount importance. This can be ensured both with free convection and with forced-convection systems.
A factor that is often underestimated when buying laboratory equipment is practical handling. Drying chambers are used on a daily basis and should be easy to load and as mobile as possible. Drying chambers on casters can be moved around quickly, which can be particularly helpful if you need to make room during long test series.
The drying chamber should feature a viewing window and, ideally, interior lighting so the visual inspection of the material can take place during the drying process rather than having to wait until it has finished.
You should also consider the noise level of the fans. The noise can quickly become a nuisance, especially when several drying chambers are placed in one room.
