PAC 4100 E local air conditioner

Maximum cooling capacity for spacious living environments

When summer days are as hot as never, the mobile PAC 4100 E air conditioner is running at its best. With a cooling capacity of 4.1 kW, which is surprisingly high for a monoblock, it refreshes rooms near the 40-degree mark in no time.

Powerful cooling for large rooms with the PAC 4100 E

High performance, fast cooling, pleasant room climate

Energy-saving cooling of rooms using the PAC 4100 E

At first sight, you would not expect the PAC 4100 E to be so powerful. But the elegant air conditioner of energy efficiency class A is a mobile power pack. It is perfectly suitable for air conditioning spacious flats, clinics and offices. However, power consumption is still low and the functions are energy-saving.

Within no time, it cools down hot rooms sized up to 54 m² to considerably fresher temperatures. However, the PAC 4100 E air conditioner also has a fully automatic dehumidification and ventilation function to create an overall feel-good climate.

You can use the long-range IR remote control or the user-friendly control panel on the air conditioner to control the operating modes (cooling, dehumidification, ventilation), the room temperature as well as the three-speed fan.

During continuous operation, the hygrostat-controlled automatic mode of the PAC 4100 E always selects the optimum operating mode required for the intended room climate. On the other hand, if you wish to use the device at specific times, as for example during the evenings, you can use the timer function for time-controlled switch-on and -off.

Tip: If you wish to air condition rooms sized up to 42 m², we recommend the little brother of the PAC 4100 E. The identically constructed PAC 3200 E A+ air conditioner fulfils all requirements for energy efficiency class A+. Power consumption is particularly low, while the cooling capacity is high (3.2 kW).

What is your required cooling capacity? An insufficient or excessive cooling capacity causes unnecessary energy costs. Just quickly calculate the required cooling capacity for your living and office spaces. Click here for more information about the calculation...

Installation and maintenance of the PAC 4100 E

The air conditioner is set up and ready for use in just a few steps.

The pre-installed air filter cleans the room air from fluff, dust and animal hair. The filters are easy to remove and clean. The condensate from dehumidification and air conditioning is collected in the built-in collecting tank. Optionally, a permanent condensate drain can be connected on the rear of the device.

A few practical benefits:

  • Three operating modes: cooling, dehumidification, ventilation
  • Significant increase of the cooling efficiency thanks to water cooling
  • Turbo cooling without more energy input
  • Low power consumption, energy efficiency class A
  • 4.1 kW cooling capacity
  • Timer function (power saving function)
  • Easy-to-clean membrane keypad
  • IR remote control
  • Three fan speeds
  • Removable air filter
