How Our Integrated Safety System Works:
High-Sensitivity Detection: The non-sparking, integrated sensor constantly monitors for R290 concentration.

Mainboard Command: Upon detecting R290 at a level significantly below the Lower Flammability Limit (LFL), the signal is immediately sent to the unit's main control board.

Automatic Mitigation: The mainboard initiates a dual, swift response:

System Shutdown: Power is immediately isolated from potential ignition sources (compressor, main contactors) and the refrigerant flow is contained.

Forced Ventilation: The exhaust fan is automatically activated, rapidly drawing the leaked refrigerant and diluting the concentration. This is a critical step for compliance (IEC 60335-2-40) and ensures the safe dispersion of the heavier-than-air R290 gas to the atmosphere.
