Can you hear the silence?

Thermo King has prioritised noise attenuation across its product range for decades, and the A-500 Whisper Pro is the quietest unit in the Advancer range — at most 60 dB(A) at a 7 m radius, compliant with even the strictest urban noise regulations like PIEK. For reference, a singing bird measures around 50 dB and a normal conversation is about 65 dB.

Geofencing — peace of mind for the driver

Authorities and municipalities have mapped the quiet zones in their cities. Advancer Whisper Pro uses these maps and switches to low-noise mode automatically when the unit crosses the geofence — the driver doesn't need to intervene and can keep their eyes on the road.

Don't compromise on cooling capacity

The Advancer range is already among the quietest on the market, and the A-500 Whisper Pro takes it further: well below the 60 dB(A) PIEK threshold, the highest cooling capacity available in a unit cleared for night-time city deliveries, and a complete package with no additional installations or services required.
