Carrier Transicold has launched a new temperature sensor calibration function for its PrimeLINE container refrigeration units, in an effort to comply with Good Distribution Practice (GDP) guidelines for pharmaceutical transport.
Reefer container shipping has lately tried to compete with airfreight over handling temperature-controlled pharmaceuticals, offering lower costs although over a long travel time.
The calibration capability will be included in software loaded into every new PrimeLINE unit, including those with Edge technology, which aims to save energy.
The calibration update involves both the Micro-Link 3 controller software and DataLINE software, which helps to retrieve unit data.
Suresh Duraisamy, senior product manager, global container refrigeration at Carrier Transicold, said: “European Commission GDP guidelines, which are used worldwide, call for the equipment to control or monitor environments where medicinal products are stored and transported to be calibrated at defined intervals, including recordkeeping of calibration activities.
“Adding calibration functionality to the refrigeration unit means temperature control sensors may now be calibrated in accordance with pharmaceutical shipper specifications, typically every six months or annually.”
In practice, service technicians will use the new software to check and automatically calibrate the refrigeration unit’s two supply-air and return-air temperature sensors.
Calibration can be done by shipping line service depots or through Carrier Transicold authorised service providers.
Carrier Transicold authorised service providers can also upgrade PrimeLINE units already in service with the latest software – Micro-Link 3 controller software, version 5368, and DataLINE software, version 3.1.
A future software revision will add the calibration capability for Carrier Transicold’s natural refrigerant NaturaLINE units.
