PAC 3500 local air conditioner
Immediately creates pleasant feel-good climate, whenever and wherever you want!
Just switch it on and enjoy the refreshing breeze!
This powerful air handling unit in compact monobloc design unites reliable air-conditioning technology and convenient equipment features with a remarkable value-for-money ratio.
Thanks to 3.5 kW cooling capacity, automatic temperature control via a digital thermostat and energy efficiency category A, the air handling unit PAC 3500 is ideally suited for cost-efficient air conditioning in workshops, hotel rooms, offices, server rooms or in exhibition stand construction and many other fields of application.
With this air conditioner you can directly enter the desired temperature value instead of using unreferenced adjustment levels between minimum and maximum operation. An integrated thermostat implements this target fully automatically and adjusts the performance of the PAC 3500.
However, this air handling unit not only cools the room air, if required it also works as powerful dehumidifier. Hence, damp walls, musty smells, rust, condensation water and mould formation is prevented.
With this model warm air can be discharged directly through the window, suspended ceilings or other ducts to the open air via a hose of 1.2 m length.
Monobloc units such as the PAC 3500 are ideal spot coolers. All of the technology is accommodated in one compact housing. The sucked-in air is filtered and fed back to the room after dehumidification.
The warmth is led outside through a flexible exhaust air hose. The window or door only needs to be opened by a tiny crack. The humidity is collected in a collecting tank in form of condensate.
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.
Convenient and cool – high performance for large rooms
Comfortably control the PAC 3500 air conditioner from your seat. All functions and settings cannot only be made via the LCD display on the device but also by means of the remote control – without even leaving your seat.
An individual feel-good climate straight to the point: Use the 24-hour timer to programme the switch-on or switch-off time of the PAC 3500 in a way that coincides with your daily rhythm. For instance, you can start into your work day with agreeable temperatures. Or use the timer to ban the heat that has built up during the day from your bedroom in time before retiring to bed for a good night's rest. The device is equipped with recessed handles and low-friction rollers permitting the quick and easy transportation into other rooms equally in need of a fresh breeze.
Air filter for animal hair, fluff and dust
The air filter integrated on the rear reliably removes animal hair, fluff and dust that is raised from the room air. This makes especially allergy sufferers and people with a sensitive respiratory tract breathe freely and deeply. The removable filter can be easily cleaned by just wiping or rinsing it. If you like to position the air conditioner in another room, it can be conveniently moved from one location to another thanks to its smooth-running wheels.
Design and functional diversity
Every room design is different. The simple and modern air conditioner blends in beautifully with nearly any kind of interior design. Whether as fan, dehumidifier or for powerful cooling – the comfort air conditioner PAC 3500 allows you to enjoy a pleasant, in-style feel-good climate throughout the year!
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 46 m² of floor space and a room height of 2.5 m.
The resulting calculation reads as follows:
Room volume calculation:
45 m² of floor space x 2.5 m ceiling height = a room volume of 115 m³
Calculation of the cooling capacity required for the room volume:
115 m³ cubature x 30 watts of cooling capacity = required cooling capacity of 3,450 watts
Conversion from watt to kilowatt:
3,450 W = 3.5 kW
Result: In a room with 45 m2 of floor space and a height of 2.5 m you need an air conditioner with a cooling capacity of 3.5 kW – such as the PAC 3500.
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.

AirLock window and door seals
ACCESSORY TIP: AirLock window seals prevent warm air from streaming back into the room you are trying to cool.
The warm air is discharged through an air conditioner's exhaust air hose and thus through a window into the open air. In order to keep the warm air from streaming right back into the room through the window gap we recommend using AirLock window or door seals.
Suitable for windows with a maximum perimeter of up to 4 metres is the window seal AirLock 100. The hose can be attached to any type of window (casement, bottom-hung or skylight windows). With the Velcro® tape mounting between window and frame only takes a few steps. This ensures an optimal cooling efficiency in the room and substantially reduces the consumption costs of your air conditioner.
Also perfect for floor-to-ceiling windows or balcony and patio doors.
The convenient door and window seal AirLock 1000 was specifically designed for sealing floor-to-ceiling windows or balcony and patio doors – it is the only window seal on the market that has a perimeter of up to 5.6 metres. The AirLock 1000 can be used for both one- or two-hose devices. Further information on all available AirLock versions is provided here.

A boost of freshness: Enjoy maximum refreshment anywhere in the room!
Do you want to additionally support the effect your air conditioner has? In order to really distribute the cool air into every last corner of the room we recommend using the powerful fan TFH 2000 E with turbo spin technology. The extremely compressed turbulent air flow gushes out of the TFH 2000 E as tornado-like air column that revolves around itself and advances deep into the room. The air current breaks through warm and cold room air zones mixing it all up. The exiting air current encounters the opposite wall or the ceiling and from there is deflected to all sides.
In a constant circulation the air returns to the rear of the fan flowing along the side walls and the ceiling. It is sucked in once more to start a new cycle. This effective turbo spin method ensures maximum circulation and mixing of the room air. The temperature difference between cold air near the ground and warm air just beneath the ceiling is substantially reduced, instead the air temperature in the entire room is noticeably evened out.
