The Rio H68S from AHT takes a different approach from battery powered ice cream displays. Plug the unit in overnight and it freezes down large eutectic plates inside the walls of the cabinet (like huge freezer packs). The unit will stay frozen for approximately 10 hours depending on conditions. A highly effective and simple way to take the ice cream to the customer. The unit comes with small castors as standard. A trolley (with larger wheels) is available, the unit is also very popular mounted onto an ice cream Tricycle.
