PAC 3500 E local air conditioner

3-in-1 air conditioner: Fast air conditioning, refreshing ventilation, powerful dehumidification

Cooling, ventilation and dehumidification with only one device

The PAC 3500 E 3-in-1 air conditioner sets new standards for design and functional diversity! On a hot summer day, hot rooms cannot be refreshed fast enough. Then you are lucky to have the PAC 3500 E with its high-performance compressor (3.5 kW). Within no time, it air-conditions rooms up to a size of 46 m² to pleasant temperatures. It is so fast you can feel it.

Since a healthy feel-good climate does not only mean to achieve the right room temperature, but also to optimally distribute the air throughout the room, the PAC 3500 E is equipped with a three-speed fan with swing function that can be switched on in addition. Fan power and air flow direction can be easily set using the provided remote control. The user-friendly timer function can be used to switch the device on and off automatically. That means saving money in times of rising energy costs!

Provides cooling at home, in the office or a hotel room – with a low power consumption

Using the flexible air conditioning system PAC 3500 E you can ban the searing heat from the house even during hot spells with record temperatures. Owing to energy efficiency category A, the ongoing consumption costs are kept at a reasonable level. In order to reduce the energy demand the device automatically ensures that the refrigerating compressor will be switched off upon reaching the preset target temperature. The device will only resume cooling when the desired temperature value is exceeded.

Fresh breeze – with and without cooling function

In addition, the elegant all-rounder comes with an adjustable three-stage fan blower with a flow rate of up to 420 m³/h. Even with the refrigerating compressor inactivated, the device provides a fresh breeze and effective air circulation in the room. With additionally activated, optional swing function, cold air will be evenly distributed in the room. In order to also filter out fluff, dust and animal hair from the breathing air, an easy-to-clean air filter is integrated on the back of the device.

Dehumidification against muggy and oppressive room air

The dehumidification performance of 1.2 l per hour allows the device to actively extract humidity from oppressive and muggy air. The result is a noticeably more agreeable room climate. Moreover, dehumidification prevents unhealthy mould growth. Due to internal condensate recycling the collection container only rarely needs to be emptied: The condensed water is reused for cooling the condenser by means of an intelligent recycling system. Consequently, the majority of water simply evaporates.

The three functions cooling, ventilation and dehumidification can be used independently which allows you to operate the stylish device in both summer time and throughout the year.

Environmentally friendly refrigerant R290

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 S 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.

Timer function

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 E 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.  

Night mode

Using the night mode function allows you to relax and drift off to sleep in a cooled bedroom. Over time the temperature is gradually increased by 2 °C and then maintained. An automatic fan stage ensures a soothing air circulation. With merely 56 dB the cooling operation of the PAC 3500 E is fairly quiet and the light of the LCD display can be switched off altogether.

Swing function

The optional on-demand swing function provides even cooling throughout the room. The air outlet automatically swings from the bottom to the top in order for the cold air distributing in an optimal way.

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 E allows you to enjoy a pleasant, in-style feel-good climate throughout the year!

Calculation of the required cooling capacity

Quick calculation of the required cooling capacity for living and office spaces

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 50 m² of floor space and a room height of 2.5 m.
The resulting calculation reads as follows:

Room volume calculation:
46 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 = 3.45 kW

Result: In a room with 46 m² of floor space and a height of 2.5 m you need an air conditioner with a cooling capacity of approx. 3.5 kW – such as the PAC 3500 E.

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.

AirLock 100 window seal

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.

AirLock 1000 door and window seal

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.
