Achieve optimal and consistent ULD performance with CSafe Global

CSafe Global’s actively controlled mobile refrigeration units for biopharmaceutical and healthcare applicationsCSafe Global, a global producer of actively controlled mobile refrigeration units for biopharmaceutical and healthcare applications, has released a white paper highlighting the problems and risk associated with using poorly maintained container stock. As a partner in cold chain management, the company often shares its expertise and knowledge to help ensure successful shipments.

Overcoming performance issues

Entitled Maintenance of Active ULDs and its Positive Impact on Operational Performance and Longevity, the paper is authored by Jonathan Neeld, CSafe’s director of certification and regulatory compliance. He discusses the problem of inconsistent performance of ageing active containers and how important it is that units – both old and new – provide comparable performance.

Some older active containers in the market place are not only badly maintained but, when tested, fail to meet their specified performance levels. ‘Life science companies have indicated that they were experiencing over 30 per cent difference in the performance and direct outcomes of some older units when compared to newer containers,’ says Neeld. ‘This difference in performance becomes problematic for the quality and validation departments, which have to make difficult justification for the continued use of older containers, as the original qualification testing was performed on newer containers.’

Scheduled and preventative maintenance

The white paper examines CSafe’s unique two-stage approach to monitoring and maintaining its container range. This was developed to ensure container performance and sets out to pre-empt any problems before they occur.

The two components of the method, as detailed in the white paper, are scheduled maintenance and preventative maintenance rebuilds or PMR.

The PMR process consists of the following steps:

  1. disassembly of the unit
  2. visual inspection
  3. verification of installations attachment and security
  4. functional testing of major components and systems
  5. scheduled replacement of certain components
  6. rebuild of the unit
  7. performance testing and temperature validation
  8. QA final inspection and release.

Both components for an interceptive maintenance process, which is carried out by factory trained technicians at the company’s strategic global service centres. This ensures the maximum safety in use for its unit load devices (ULDs) which is a vital consideration for health products and life-saving drugs.
