The new dollies are called “Cool Box”. They enable temperature-sensitive products to be transported with pinpoint accuracy within a range of minus 20 to plus 30 degrees Celsius. Each transporter consists of two cabins that can be efficiently accessed from both sides. Each cabin is also equipped with an individual controllable cooling system. Even with the engine off and an outside temperature of 30 degrees Celsius, one cabin maintains the desired temperature for more than 60 minutes. The transporters continuously transmit up-to-date information on the load via an electronic temperature monitoring and tracking system.
