World Cargo News: Rethinking the cold box
Dutch company BoTemp continues to develop technology to support passive refrigerated transport systems that do not require continuous electrical power from a mains supply or a genset.
BoTemp has over 30 years experience in “passive refrigeration” technology utilising the thermal energy storage capacity of phase change materials (PCM). Its new dynamic “Cold Battery” system uses stored thermal energy to remove heat by circulating a cold transfer fluid from the Cold Battery through a liquid/air heat exchanger in the cargo space to control the temperature anywhere from -20 to +4 deg C. A Cold Battery can be mounted on or under a truck, trailer or container, or can be used in stationary applications, like cold stores, as a contingency back-up refrigeration source, or as part of an energy demand management system.
