RolaFrigo is an insulated curtain developed by Roland to control load temperature.  The system is normally supported by a refrigeration unit and air ducts.  It is usable for international vegetable, fruit and flower transport as well as for the distribution of pre-refrigerated beverages. 

The insulation layer consists of a rot- and fungus-resistant, non-woven construction and is installed on the inside of the side curtain.  The insulation is then protected by special PVC coated sheeting on the inside of the curtain.
