Product in its environment

Making an order; your app will determine required temperature for each item according to its barcode and creates a unique code to send to supplier.

When delivery man starts entering this code you will be notified and the external camera will be turned ON sending a live stream video to your mobile.

Product views

Entering code opens external fridge door, locks the internal and turns internal camera on.

Depositing order and pushing END button closes external door, unlocks internal and turns both cameras OFF.

In multi chambers versions; an electro mechanical lift replaces the used chamber with an empty one.

Product in use

When a multi item order arrives, with different temperature for each item, the solution is the heterogeneous distribution of temperature.

This electronically controlled system pumps cold air in a regulated manner across several nozzles, providing each item with the required temperature accurately.

Additional info

When there is no enough space next to front door, you can hang a wall mounted type near the stairs or in the Lobby.

You have the choice between different sizes (40 - 200 liters).. The standard (microwave size) and multi chambers (up to 5) with the same outdoor shape and different indoor heights.
