How a delivery works and how the locker is kept under control.

Fixed compartment assigned to each housing unit: no order, no delivery PIN.
The courier opens the door by tapping the resident's name on the display: no account, no integration.
Automatic closing; reopening within 3 minutes, once only, to finish loading.
Alarm if a door fails to close.
Delivery SMS triggered by the weight/presence sensor; the resident opens with a permanent personal code.
Video surveillance and 24/7 monitoring: temperature, power outage, connectivity loss.
Role-based access: technical team, property manager, resident.

Built to measure, ready to connect

Sized to the developer

Fresh Locker 20 is the standard configuration. The locker is built around the developer's needs and measurements, from a minimum of 4 doors up to several hundred.

Plug and play

Delivered plug and play: the developer only needs to provide the electrical connection and a LAN line. The optional 5G connection ensures communication over the mobile network in case of disconnections.
