SLXi-DRC units are equipped with TracKing ConnectedSuite communication device that when enabled allows remote access to unit data. Downloading the Thermo King Reefer mobile app, will allow you to monitor and manage temperature and reefer settings over the road, in the yard or in-cab via Bluetooth®.
This allows an entire fleet to be configured to match the customers’ needs. Contact your Thermo King dealer for information about programming OptiSet Plus.
FreshSet is included in OptiSet Plus. FreshSet is a demand base temperature control for fresh products. FreshSet modifies and adjusts unit airflow operation to control temperature and to maximize protection of cargo, while keeping operating costs to a minimum.
