- Delivering full climate control where traditional AC is not possible
Cooling, heating, and ventilation are often a challenge in places where traditional air-conditioning with external condensers is banned, impractical or unsafe. Protected historic buildings or container-based accommodation also require reliable indoor comfort but are often under architectural, technical, or economical constraints prohibiting external units, pipe work, large footprints or specialist installation.
Being designed for fast deployment, the PAC-W 2650 SH solves these exact problems through its key capabilities:
- No external condenser unit
- Only two small wall penetrations (Ø180 mm) required for air intake and exhaust plus a 20 mm drainage for the dehumidifier
- Indoor module just 20 cm deep fits high or low on the wall
- Quiet operation: 48 dB(A) suitable for offices and sleeping quarters
- App-based remote control allows facility management to adjust climate settings from anywhere
- Installs in minutes without AC technicians

Small footprints, wide range of applications
The unit installs entirely indoors, requiring only two small external air grilles and a 20 mm drainage duct which unlocks climate control in cases where conventional AC systems simply can’t be used.
The multiple cases for the PAC-W 2650 SH:
Historic and heritage buildings. The absence of an outdoor condenser leaves the facade intact with no visible changes and minimal impact on protected architecture.
City-centre offices. Again, the fully indoor installation of the AC complies with restrictions on external units and avoids disputes about the building’s appearance.
Containers and modular buildings. No bulky outside hardware makes the AC perfect for stacked worksite containers, guard cabins, IT rooms and portable offices.
Temporary accommodation and rented property. No complex piping, easy redeployment, and inexpensive installation makes the PAC-W 2650 SH a very landlord-friendly AC solution.
Private one-family houses. Single residential buildings can also take advantage of the easy installation and clever design where a clean exterior is preferred.
The slim and stylish appearance of the indoor unit allows it to fit easily into any indoor environment.
One unit serves a room of 15-34 m2.

4-in-1 climate performance
In addition to its unobtrusive design, the PAC-W 2650 SH stands out as a four-season-all-weather climate solution. As a single compact wall-mounted appliance it provides year-round indoor comfort:
- Cooling with inverter technology (energy class A)
- Heating via heat-pump system (energy class A)
- Ventilation with 3 airflow levels
- Dehumidification rate: 1.2 l/h
The compressor adapts intelligently to conditions, delivering up to 30% lower energy consumption than non-inverter AC units. The power consumption is merely 1 kW.

Quick comparison of AC solutions
PAC-W 2650 SH | Conventional split AC | Portable AC |
No external condenser required | External condenser required | External condenser required |
Clean façade, indoor-only installation | Prohibited or visually disruptive | Requires open windows or other opening |
48 dB | 50-70 dB | 50-70 dB |
No AC technician required | Professional AC technician required | No training or installation work needed |
Overall, the PAC-W 2650 SH provides comfort you can install where AC seemed impossible, enabling preservation of historic facades or delivering climate-ready workspaces in stacked containers.
