Triple power for extra freshness: cooling, ventilation, dehumidification
Refreshingly convenient. As flexible as possible.
With cooling technology of the latest generation as well as a comprehensive functional range the multifunctional air conditioner PAC 3900 X lives up to its reputation as genuine all-rounder. For cooling, ventilation or dehumidification: The ultra-compact air conditioner meets all requirements of an ideal room climate with flying colours. With a cooling capacity of 3.9 kW the air conditioner of the PAC series is especially well suited for large rooms of up to 130 m³. Apart from the reliable cooling on hot days the PAC 3900 X filters and dehumidifies the room air and generates a fresh breeze to top it all off. As desired in three fan stages and with swing function for an optimal distribution of the air in the room.
Functions of the PAC 3900 X
The PAC 3900 X comes equipped with a modern microprocessor control and a variety of individually programmable functions. Optionally, the device regulates the room climate autonomously. The smart air conditioner even automatically reduces the energy costs by switching off compressor and fan when reaching the predefined target temperature.
The operating modes ventilation and dehumidification can also be selected with deactivated cooling function. Therefore, the 3-in-1 air conditioner PAC 3900 X can be used throughout the year to create a healthy, agreeable indoor climate – whilst keeping the power consumption at a minimum. This further reduces the energy demand of the already economical device and renders the purchase of a separate fan or dehumidifier redundant.
The integrated timer function permits operation by the hour as well as automatic switch-on and -off. An agreeably silent night mode with adapted temperature control guarantees a good night's rest and the necessary physical regeneration.
Propane (R290) as environmentally friendly refrigerant in air conditioning systems
Every year, several million tons of harmful CO2 emissions (greenhouse gas) are emitted to the atmosphere due to synthetic refrigerants. For this reason, the utilization of alternative refrigerants has become one of our key objectives. By using propane (R290) as refrigerant this air conditioner makes a valuable contribution to protecting our climate.
The natural refrigerant propane (R290) is an organic compound belonging to the group of hydrocarbons. Unlike synthetic refrigerants the environmentally friendly propane (R290) comes with neither ozone depletion potential (ODP = 0) nor a noteworthy greenhouse effect (GWP = 3).
Additional bonus for the environment: Owing to its excellent thermodynamic properties, propane (R290) is a particularly energy-efficient refrigerant thereby additionally reducing your energy costs.
More time for the things that matter!
The set operating parameters such as mode, target temperature and fan stage will be saved when switching the device off and then automatically adopted for the next switch-on.
The monobloc air conditioner PAC 3900 X is optionally controlled via the supplied IR remote control or the neatly arranged control panel with membrane keys.
Installation and maintenance of the PAC 3900 X
Ready for use in a breath.
If required, the already preassembled air filter can be removed and cleaned unproblematically. The humidity is collected in a collecting tank in form of condensate. If required, a permanent condensate drain can be connected at the rear of the device.
Mobile, minimum space requirements, low in maintenance
Of manageable size, versatile, intelligent design.
The bedroom today, the living room tomorrow? That is no problem at all. On the low-friction rollers, the device can be easily moved from one location to another at the ergonomically shaped recessed handle. When storing the device at the end of the cooling season, the cable can be easily stored using the practical cable winder.
One air conditioner – manifold application options
With its three operation modes cooling, ventilation and dehumidification the powerful and flexible all-rounder PAC 3900 X is recommended for use at home or in the office.
Calculation of the required cooling capacity
Find out how to easily calculate the cooling capacity required for your living and office spaces.
How much power is required to cool a room? The rule of thumb: Every cubic metre of room volume requires a cooling capacity of 30 watts (1 m3 = 30 W).
Using this blanket value the required cooling capacity can be determined quickly and easily for every room size. Example: Assuming a room with 52 m² of floor space and a room height of 2.5 m.
The resulting calculation reads as follows:
Room volume calculation:
52 m² of floor space x 2.5 m ceiling height = a room volume of 130 m³
Calculation of the cooling capacity required for the room volume:
130 m³ cubature x 30 watts of cooling capacity = required cooling capacity of 3,900 watts
Conversion from watt to kilowatt:
3,900 W = 3.9 kW
Result: In a room with 52 m² of floor space and a height of 2.5 m you need an air conditioner with a cooling capacity of approx. 3.9 kW – such as the PAC 3900 X.
This is only a rough calculation formula for living and office spaces with modern insulation (passive house standard), though. The required cooling capacity further depends on the room's "thermal load": For selecting an appropriate air conditioner, the factors of insolation, insulation, window dimensions, the number of persons as well as the heat sources play an equally important role.
PAC 3900 X – special equipment features
The compact air conditioner clad in stylish black and white blends in perfectly with any living or working environment. With 3,9 kW / 13.300 Btu/h it brings a pleasant fresh breeze to rooms sized up to 52 m² or 130 m³.
The energy consumption of an air conditioner is an important factor. With energy efficiency category A you can be on the safe side that your electricity costs will keep within reasonable bounds. With functions for condensate recycling and timer-controlled switch-on/off, the device itself permits a rather efficient and economical cooling operation.
The swing function can be switched on if desired. The air outlet flap is automatically raised and lowered in order for the cooling air current to distribute evenly in the room.
The air filter integrated at the rear of the device cleans the room air from dust, fluff and animal hair. It can be removed without difficulty and cleaned without great effort. All in all the PAC 3900 X combines an uncomplicated, quick and easy installation, maintenance and servicing.
The stylish, neatly arranged LED display reveals all important setting options at one glance and so offers a very intuitive operation.
All functions and settings can also be carried out via infrared remote control. Whether at home or in the office – this allows you to adjust the air conditioner conveniently from your seat, according to your individual requirements.
The device comes equipped with wheels. The integrated recessed handles serve for the quick and easy transportation of the air conditioner from one room to another.
With the cable winder, there is no trip hazard and the cable is not lying around.
