What is the origin of advanced diagnostics in refrigerated vans?
Adoption of diagnostics in refrigerated transport emerged as a response to increasing risk management needs within temperature-sensitive logistics. Early solutions employed manual checks and rudimentary alarms, insufficient for a market shaped by mass distribution and global movement of perishables. Detection of failures often lagged behind events, resulting in spoiled cargo and uncertain audit trails. The food safety movement and pharmaceutical integrity protocols, such as Hazard Analysis and Critical Control Points (HACCP) and Good Distribution Practice (GDP), highlighted the inadequacy of traditional methods and spurred development of automated, data-driven diagnostics.
How did regulatory and technological changes drive development?
The evolution of digital sensors, microprocessors, and secure communication protocols coincided with expanded governmental regulation of cold chain logistics. Regulations demanded not only temperature control but also robust digital evidence, tamper prevention, and traceable event records. The appearance of electronic refrigeration controls enabled continuous data capture, while legal mandates, such as the European Union’s GDP and widespread adoption of HACCP, transformed diagnostics from a competitive edge to a compliance expectation. Innovators such as Glacier Vehicles responded by integrating digital platforms and partnering across technology, manufacturing, and compliance sectors, establishing blueprints for responsive, standardised diagnostics.
What technical architecture underpins GAH Connect diagnostics?
