Humidifiers for Museums & Archives
Professional climate control to protect valuable collections
Why is precise humidity control crucial in museums?
Air that is too dry causes wood to shrink, makes paper brittle, and can cause cracks in paintings. Air that is too humid promotes mold growth and accelerates chemical degradation processes. The recommended range is 45–55% relative humidity—maintained at a constant level with minimal fluctuations.
- Protection Against Cracks in Paintings and Wooden Sculptures
- Preservation of Historical Documents and Books
- A stable environment for loaned items and permanent exhibits
- Compliance with climate control standards for conservation (DIN EN 15757)
Precise control ±2% RH
The combination of intelligent control and the natural evaporation principle ensures stable humidity levels—for safe operation and optimal protection of valuable exhibits.
Naturally safe evaporation principle
The evaporation principle virtually prevents over-humidification on its own. This makes our humidifiers a proven solution for sensitive environments such as museums, archives, and storage facilities.
Hygienic & mineral-free
During evaporation, only water molecules are released into the room air. Minerals and limescale remain inside the unit, preventing the formation of deposits. The result is hygienic humidification for demanding applications.

Humidifier B 260: robust, durable, easy to use The disc evaporator B 260 convinces with its robust outer housing made of painted sheet steel and the high-qualityplastic elements, which additionally enhance the humidifier and give the product a high durability. Simply cleanIn the B 260 humidifier, the ambient air is drawn in from the room via a special air filter. This pre-cleans it, which helps to reduce pollution of the air and the inside of the unit and thus supports clean operation. The air is then passed through a rotating, moist evaporative filter disc, which is very robust against dirt due to the special material. At the same time,the surface structure of the evaporation filter disc ensures a particularly large evaporation surface (3 m²) due to its special design and thus produces a high, uniform and energy-efficient evaporation according to the cold evaporation principle. In the process, the moisture is released into the room air in gaseous form and foreign substances such as limescale ordirt remain in the unit. Comfortable The structured design of the unit makes maintenance work child’s play. The front grille can be easily removed to the front, thus providing quick access to the evaporative filter disc and the water tank, which can then be pulled out to the front. This allows the tank and the filter to be transported to a sink for cleaning without much effort. The air filter can also beeasily removed and replaced by removing the rear grille. This allows you to carry out maintenance work on the unit quickly and without the use of tools, which supports hygienic and long-lasting operation. Overview The control panel of the B 260 provides quick and clear information about the current humidity in the room, the set fan speed and the fill level of the water tank. If there is no more water in the tank, the unit switches off automatically and signals this to the user by a flashing LED. Convinving Arguments Fast commissioning without installation effort Operation with normal tap water Humidification without precipitation and no limescale on furnishings and fittings high evaporative capacity Electronic control with percentage-accurate humidity measurement and automatic switch-offwith empty water tank Simple operation with the option of setting the target humidity and the fan speed Robust filter due to special filter foam Pre-cleaning of the air by separate filter in the intake area Optional accessories Radio humidity transmitter Optionally, the B 260 can be equippedwith a Radio humidity transmitter.

The B 280 at a glance Healthy living and working in optimum air humidity: warm air can hold more moisture than cold air. Therefore, the percentage of moisture in ambient air is expressed as the % of relative humidity – a relative humidity of approx. 50-60% is considered to be optimal. In living spaces a temperature of 20-23°C is considered to be ideal, while the ideal room temperature in the bedroom is max. 18°C and for the workplace it is 18-23°C. Particularly in wintertime, a constantly comfortable humidity can be reached by humidification of the indoor air. Key benefits: • electronic control • ready for use – stationary or mobile – without installation • clear control panel with display of the water level, fan speeds, ionization operation and the actual and desired humidity in 1% steps • durable, corrosion free and easy-to-clean plastic housing • adjustable air vents on top • hinged control panel • low power consumption • high reliability through 24-volt operation • low noise emissions • air-cleansing through separate pre-filter and ionization • 8-stage fan with additional automatic function • high evaporation performance through large filter surface • suitable for tap water and purified water • humidification without precipitation and scale deposits in the room Typical examples: • Living rooms • Offices • Music rooms • Libraries • Museums • Galleries • Data processing rooms • Call centers • Laboratories • Archives • Print shops • Hospitals Functionality The humidifier B 280 works on the principle of cold evaporation. It is generally recognized that this manner of operation is best suited for humidifiers. The air is sucked in through a special dust filter at the rear panel and thereby pre-cleaned. Then it passes through the humidification filter, where it is being enriched with plenty of moisture due to the large evaporation surface. Finally, the humidified air exits through the exhaust opening at the front, back into the room. In addition, various other exhaust openings on top of the unit can be opened, providing a more directed distribution of moist air. Fan The B 280 has nine - eight manual and one automatic - air fan levels available. In automatic mode, the unit adjusts the speed – and thus the humidification – automatically to the current needs: the larger the difference between the actual and desired humidity, the faster the fan will work. If the actual humidity approaches the set value, the automatic mode reduces its performance accordingly. Alternatively, eight manual speed settings can be used; these offer the user the opportunity to adapt the performance and the noise level of the B 280 to your individual needs. Operation The control panel of the B 280 offers you fast access to the functions of the unit and informs at a glance about the current situation: humidity value, fan mode, water level (full or empty) and ionization (on or off) are displayed and can be set. In addition, the very clearly designed control panel can be positioned in such a way, that controlling the display becomes even more comfortable. Moisture Control The B 280 has an internal moisture sensor, which constantly measures the current humidity and then displays the value percent accurately on the display. After adjusting the desired nominal humidity value, the device adopts the control autonomously and ensures that the desired value is reached. In the event that particularly accurate humidity values are required, the B 280 is optionally available with a separate humidistat. Ionization The concentration of ions as well as the ratio between positively and negatively charged ions in the ambient air contributes to the air quality. With the ionization of the B 280 you can therefore enhance the quality of the air and thus the wellbeing. Since dust particles accumulate at the ions, the ionization also cleans the air. Water level indicator The unit monitors the filling level of the water tank. Once it is empty, the unit switches off automatically and informs by an indicator on the control panel that water must be refilled. Keyboard lock The B 280 has a keypad lock, which can be activated by means of a hotkey and disables input on the control panel. This way, intentional or accidental changes of the set parameters by unauthorised persons can be prevented. Filters The evaporation filters of the B 280 are made of special filter foam, which has a particularly large evaporative surface due to its porous structure. This ensures the significantly high evaporation performance of the B 280. Options Optionally, the B 280 is available with an automatic water supply, which enables connection of the unit to a water pipe. This eliminates having to manually fill the unit with water. For safety reasons, we recommend the use of appropriate safety accessories as well (water monitor, safety pressure hose and safety collection reservoir). For high-precision humidity value measurements in the room, the B 280 is also available with a wireless sensor system. The humidistat can be placed anywhere in the room and transmits the moisture readings to the unit. Moreover, this system allows a combined operation of the B 280 and the HP 50 dehumidifier. As another option, the B 280 humidifier is available with a UV-C lamp for disinfection. The central position of the lamp makes that the water in the tank, the secondary air, and the inner evaporative filter are subjected to UV-C rays, creating a germ-reducing effect. NOTE: Some discoloration may occur around the UV lamp. This does in no way impair the function or the structure of the unit, and thus does not constitute a fault. Notice:· Regular cleaning and filter changes in accordance with the operating instructions are necessary to ensure hygienic use. · The usual precautionary measures must be taken when handling electrical appliances in order to avoid damage to persons and material. Further information can also be found in the operating manual.· Warning against UV radiation. The optional UV lamp may be visible from the outside; direct view of the UV light should be avoided.

The Air Humidifier B 300 doesn’t only provide a comfortable and healthful indoor climate in living spaces, but also protects valuable fixtures and furniture against possible damage from excessively dry air. The FanThe fan with auto function – easy switch-offYou can opt between two functions - "manual” or "automatic”. At the manual setting the fan’s performance is adjusted by choosing "high” or "low" or selecting the auto mode. In the latter, the output is controlled electronically; generating a higher or lower output, depending on the requirements of the surrounding air quality. Air and water purification with germicidal UV-C raysA clean jobUV-C rays have a sterilizing effect which is highly effective. Consequently, they are already being used extensively in the process of water treatment. The clever configuration of the germicidal UVC lamp in the B 300 allows water in the water reservoir, the drawn-in air, as well as the filter medium to be "UV-C-rayed". The UV-C lamp provides for optimum germicidal intensity, producing healthier indoor air. This procedure is completely ozone-free and imposes no health risks. Air cleaningClean all around An additional air filter in the air intake duct of the fan filters out dust and other particles. Afterwards the air is passed through water and exhausted back into the room through the evaporator filter, which ensures additional air cleaning. In combination with the intensive disinfecting through the UV-C-lamp, an efficient air treatment has been made possible that ensures even cleaner air. The Water level indicatorThe reservoir doesn´t have to be removed. The control panel informs you about the humidifier’s water level. If the reservoir is empty, the humidifier will shut off automatically and a flashing light will signal that the reservoir must be refilled. Humidity controlNo more worriesYou can leave it to the control system. You can set the humidity level by pressing "+” or "-". The humidifier operates until the selected level is reached and then shuts off automatically. If the humidity level falls below the one originally selected, the humidifier unit switches back on.

Humidifier B 600 professional: Mobile professional large-capacity humidifier for the highest demands. Its structured design, the use of high-quality materials and high performance make the B 600 humidifier a reference in the mobile humidification segment. Its extensive range of accessories makes it flexible, easy to use and ready for immediate use without any major installation effort. The further development of the B 500, appreciated by customers all over the world, also effortlessly meets professional requirements and supports them in maintaining constant climate conditions. Via the WLAN/Wifi system built in as standard, the units can additionally be controlled and operated remotely via the Brune Control App using a smartphone. With the app, you can switch the humidifier on and off, set the humidity and fan levels, receive error messages and much more. The app is available free of charge in the App Store and Google Play Store. The use of the radio humidity measurement system makes the B 600 a true team player. It can be operated together with other humidifiers and dehumidifiers from Brune via a common radio humidity transmitter. The devices thus receive the identical measured value. Due to this overlap-free interaction of the devices, a humidity control system can be created by combining humidifiers and dehumidifiers. This allows a desired humidity corridor to be created in the room. In addition, the devices can be monitored and controlled remotely via the standard built-in Wlan/Wifi system. UV disinfection and lime conversion: UV technology produces a short-wave light that destroys the cell structures of most microorganisms and germs, killing them. In the B 600, the humidifier water is permanently pumped through a stainless steel body in which a UV low-pressure lamp, protected by a quartz glass, has been installed. This creates a thin layer of water between the quartz glass and the stainless steel body, which is irradiated and sterilized very intensively and effectively due to the short distance to the lamp. The purified water is then returned to the water circuit and fed directly to the evaporation filter via the lime conversion cartridge. The lime conversion cartridge uses permanent magnets to generate a magnetic field that changes the molecular structure of the lime in such a way that it is less likely to be deposited on surfaces in the unit. In this way, the evaporation filter is permanently supplied with clean, decalcified water with reduced germs. Hygienic operation through air filtration: Before the air is fed into the unit, it is pre-cleaned by filtering out dust and particles already in the intake area. Different filter types (coarse dust, F 7 and H 10) are available for this purpose. In addition to the general air improvement, the pre-cleaning supports the hygienic operation of the humidifier. During the evaporation process itself, minerals and lime from the water remain in the evaporation filter of the unit.This prevents lime deposits on furnishings. Regular replacement of the filters supports the function and trouble-free operation of the device. The adjustable filter change indicator supports you in this. In winter operation, at the customer's request, the air filtration can be reduced by using the coarse dust filter in favor of the evaporation capacity. However, we recommend the use of the class F 7 filter in combination with the coarsewith the coarse dust prefilter. In summer operation, the humidification function in the operating display can then be deactivated and the B 600 used for air purification. In this case, the use of the higher pre-filter classes (coarse dust in combination with Hepa H 10) and the use of the activated charcoal filter as a replacement for the evaporative filter is recommended. The activated carbon filter additionally absorbs odorous and gaseous substances and thus additionally increases the quality of the air. Please note, however, that the activated carbon filter is not suitable for evaporative operation! Even more comfortable in connecting: The B 600 works with normal tap water or also with treated water. By using a new float technology, the water level measurement of the B 600 works independently of the water quality. Furthermore, the B 600 uses modern quick coupling systems for connection to the water or wastewater network, which allows easy installation or deinstallation without tools. These innovations promise reliable operation and easy handling of the direct water connection. Manual refilling is eliminated, making operation even more convenient. Water is supplied via an electronically controlled solenoid valve that opens when the minimum water level is reached and stops the water supply at a preset maximum level. An automatic flushing device is also available as an option for the B 600 Professional. This gives you the option of simply replacing the water in the tank, thereby reducing limescale and dirt deposits. The residual water is pumped out of the tank via a separate flushing pump and automatically replaced by fresh water using the direct water connection. You can trigger the rinsing process yourself via the touch display of the B 600 or program an automatic rinsing interval. The flushing pump can also be used as a safety pump. If the alarm level is exceeded, it pumps out the excess water until the normal level is reached again. In addition, a warning tone sounds and is shown on the display. Easy operation thanks to a modern display: The modern touch display informs you about the operating parameters such as current relative humidity, room temperature, fan level, maintenance indicators or warning messages. Due to the language selection options, there are several languages to choose from, which significantly increases the comfort. In addition, you can switch to further submenus and make various settings yourself (timer, radio coding, maintenance intervals, pin assignment, Wlan/Wifi settings). Thus you can program the B 600 according to your own ideas and adapt it to your circumstances. Notice: · Regular cleaning and filter changes in accordance with the operating instructions are necessary to ensure hygienic use. · The usual precautionary measures must be taken when handling electrical appliances in order to avoid damage to persons and material. Further information can also be found in the operating manual. · Warning against UV radiation. The optional UV lamp may be visible from the outside; direct view of the UV light should be avoided.

Precision Humidifiers for Museums, Galleries, and Collections
Precious exhibits made of paper, canvas, or wood are highly sensitive to fluctuations in indoor climate. In museums and galleries, a constant relative humidity between 45% and 55% is essential to prevent material stress, cracks, or brittleness. Our professional humidifiers operate on the safe principle of cold evaporation, which physically prevents over-humidification and leaves no limescale deposits on works of art. Ensure the long-term preservation of your collection’s value through reliable climate control that meets strict conservation requirements. If you have any questions about the optimal placement of these units in your exhibition spaces, we’d be happy to assist you.
Preservation through stable humidity levels in the air
In exhibition and storage spaces, dry heated air in the winter poses one of the greatest threats to cultural heritage. Organic materials are hygroscopic; they absorb or release moisture, which leads to permanent changes in volume. Especially in the case of valuable oil paintings, antique furniture, or historical documents, this process quickly leads to irreparable damage, such as paint flaking or warping of the paper.
A high-performance humidifier helps stabilize these dangerous fluctuations. Thanks to modern sensor technology, our devices maintain the humidity level exactly at the target value. The built-in wireless sensors enable precise monitoring without the need for complex wiring in historic buildings.
Another advantage of cold evaporation in museums is its purifying effect: As air flows through the moist filter mats, dust particles and pollutants are trapped. This reduces the amount of cleaning required for display cases and exhibits and also helps protect the surfaces. Our systems are designed for continuous operation and are so quiet that they do not disturb the peaceful atmosphere of the museum.
