We punch, edge, solder, weld, glue and screw in our factory in Zurich. With the aim of producing the best dehumidifier. Our intelligent condensation dehumidifiers and effective dehumidification systems control and monitor humidity and temperature in archives, museums, garages and wherever active climate management is required.
Technical specifications, instructions and details on all products, components, devices and systems can be found in the DOWNLOAD section.
We enable installation on brackets up to a maximum height of 2.40 m from the floor. This keeps the way clear and there is no risk of injury in the basement of apartment buildings, bicycle rooms, production halls and warehouses / archives. Our technicians also carry out core drillings through concrete and brick, guide the condensation water in Geberit PE to the nearest drain or install the condensation water pump.
Those who prefer to remain flexible can opt for the mobile version. Ideal for garages, production facilities, civil defense facilities and many other applications. Individually available with an overflow protection device or the prepared connection for drainage via a hose into a floor drain.
The control system developed by LUNOR is crucial for efficient operation. Whether in new or existing properties: We will find a solution for your dehumidification system. During our on-site survey, we record your requirements and offer you the entire installation. From core drilling to ventilation pipe installation, you receive everything from a single source.
Vaporous, liquid or solid.
Depending on its physical state, water is vaporous, liquid or solid. There is always a certain amount of moisture in our ambient air in the form of water vapor. The warmer the air is, the more moisture it can absorb. If the air cools down, the situation is reversed: the air can no longer hold the moisture and it condenses on cold surfaces.
Lunor L-series dehumidifiers work according to this principle. Refrigerant is evaporated in a heat exchanger by means of a compressor, which cools its surface considerably (the evaporation temperature depends on various conditions). The humidity flowing past it condenses, the air warms up again and is blown out at room temperature and dry.
Relative humidity = effective amount of water in g/kg air.
The term relative humidity means that the air is saturated to the specified percentage. When we talk about 60% relative humidity, this figure only means that one unit of air is 60% saturated with water. We do not know how much water this actually is in g/kg. We only know that the air is still able to absorb a further 40% before condensation occurs. We also need to know at what temperature - and, if we are precise, at what air pressure - the corresponding measurement was taken.
From the HX diagram we can read that air with 60% at 20°C at approx. 450 m above sea level contains an effective amount of water of 9.2g/kg air.
If we cool this air down to 16°C, the relative humidity rises to 80%. However, it still contains 9.2g of water per kg of air. If we now create a cold surface that we cool to below 12°C, the humidity rises to 100%. The water vapor begins to condense and we speak of the dew point being reached.
Bathroom mirror or cellar wall - the principle remains the same.
The theoretical approach is easy to understand when your own reflection is no longer visible after a shower due to tiny drops of water. The colder mirror acts as a natural dehumidifier and the shower vapor condenses on the cold surface. The phenomenon is most visible on the mirror, but the walls, ceiling and floor are also covered in very fine condensation.
These physical principles lead to enormous moisture damage, especially in uninsulated basements. If warm and humid outside air cools down in the basement, the relative humidity rises. Moisture damage to stored goods occurs from 65%-70%RH, depending of course on what is stored. If the humidity is constantly at 65-85%RH, mold can form and grow.
Outside air may therefore only enter the cellar if the effective amount of water in the incoming air is lower than the existing air in the basement. As a rule of thumb, this condition only applies in the cold winter months. Dehumidification via ventilation requires some know-how and may only take place with a well thought-out control system.
An efficient cooling unit requires a well thought-out control system to ensure that dehumidification runs efficiently. The most important factor here is the positioning of the hygrostat (the measuring point), which determines the operation of the system. All Lunor dehumidifiers are hygrostat-controlled. Simple on/off control or control via a timer is not recommended.
The aim is to monitor and, if necessary, dehumidify the room climate. The hygrostat must therefore also measure the room climate. The sales argument "internal hygrostat" suggests safety, but often leads to incorrect measurement results and thus to unnecessary running times and energy consumption. If the hygrostat is placed in or on the appliance, it must be ensured that it measures the room climate and not a microclimate created in the dehumidifier.
Internal hygrostat.
In Lunor dehumidifiers, the hygrostat is always located outside the appliance. As standard on the housing, an external hygrostat is available on request instead of the hygrostat on the appliance. With our dehumidification systems
External hygrostat.
The external hygrostat allows the measuring point to be moved by several meters and into other rooms. Specifically, measurements are not taken in or on the dehumidifier, but several meters away from it. The external humidistat therefore contributes to more precise regulation of the humidity in the entire room to be dehumidified.
Adjust the humidistat correctly.
The dehumidifier is adjusted over a longer period of time. A hygrostat with display in the room (available from specialist retailers or from Lunor) shows the measured relative humidity in the room as a percentage. If this value is too high, turn the hygrostat down. If the value is too low, the value can be corrected upwards.
Monitoring the dehumidification performance.
If no dehumidification takes place despite the signal from the hygrostat, the monitoring system sends a signal to the building management system via a potential-free contact.
Climate monitoring.
In contrast to dehumidification performance monitoring, climate monitoring sends a signal to the building management system if the relative humidity is above a defined maximum value. This prevents moisture damage caused by incorrect manipulation of the dehumidifier: If the humidity rises too high, either the hygrostat on the dehumidifier is set incorrectly, the dehumidifier has been unplugged or it is faulty.
