HTW IX21E Technologies
| AI ECO+ Predictive | An artificial intelligence system that continuously analyzes environmental conditions and user preferences to automatically optimize operation, reducing consumption by up to 40%. |
| Self-cleaning 56°C | The equipment heats the evaporator to 56°C to eliminate mold, dust, mites, and grease, keeping the unit sanitized without the need for frequent manual intervention. |
| Golden Fin | Special anti-corrosion coating on the heat exchanger fins increases resistance to moisture, salt and pollution, significantly extending the equipment's lifespan. |
| 3D airflow | An air distribution system that combines horizontal and vertical movement to ensure uniform climate control throughout the room, eliminating hot or cold zones. |
| Multilayer filters | Three layers of filtration: catalyst (decomposition of organic compounds), activated carbon (odor absorption), and silver ions (bacteriostatic action) for cleaner air. |
| I-Feel | A temperature sensor incorporated into the remote control measures the temperature near the user (not near the unit), ensuring more precise and comfortable climate control. |
| Removable PCB | The printed circuit board is easily removable, allowing for the replacement of electronic components without the need to disassemble the entire internal unit. |
