Getting technology to work for you.

If you get the opportunity, think differently. Every now and then, an advance in technology opens new doors and ideas. When we first researched the current approach to cooler/fridge management, we became aware of concerns with the existing processes. The excessive paperwork, temperature logging inaccuracies and a lack of performance feedback. Plus non productive use of staff time.

But above all, what are we working with and what do we want to achieve?

So we started with a clean sheet, some good ideas and an eye on the latest Internet of Things developments.

We built prototypes and set about actually surveying the performance of food, medication, freezers, kitchens etc specifically in the healthcare sector.

The first presumption was basically this. If you never open a fridge or cooler unit, it will likely work perfectly until the wheels fall off.

However healthcare medication, food prep and storage is not like that. It’s a 24hr moving target with medication deliveries, dispensing, food stocking and more. Constant demands on the coolers and fridges. Human error comes into play. Maybe fridges are low quality and inadequate.

We ran continuous plots for weeks which showed what the temperature patterns were. Sometimes erratic and sometimes going off chart.

What was very apparent was that sticking a thermometer in the fridge randomly twice a day was not going to catch the action. At a seriously high level, we recorded cooler limits going north and taking four hours or more to recover. Damage done maybe but likely never recorded, known about or logged.

We noted variations from compressor failure (see above) through to overstocking.

Most frequent cause of temperature breakouts? Doors not being closed properly. Just 10mm open is enough for temperatures to rise. Even if discovered, it’s too late.

You need to know before it gets worse.

The industry’s mea culpa is that you really need to have someone checking fridges continually. But that is not humanly practical. So the present twice a day dip of a thermometer, until now, was the only feasible compromise.

But Technology moves on..


The result was MimoCool.

By exploiting this new IoT technology, we were able to think outside the box and bring some novel new approaches to the management and reporting of Cold Chain Storage. (See RegTech)

The Challenges we needed to meet

  • Record profiles every few minutes. A lot can start to happen in six minutes.

  • Get the message out quick. And if temps still climbing north call out again.

  • Record for post-mortem. Detailed breakdowns, times and logs of each exception

  • Be able to replay and display the circumstance of any failure.

  • Monthly summary report on worst failing coolers. Enable drill down to individual days, hours and minutes of poor performance

  • Must be 24/7 monitoring.

  • Must be out of box user install. No expertise needed. Up and running in no time. No white van man. Sensors in fridge and shut the door.

  • Cold storage units can be spread over long distances. So no infrastructure or cabling work.

  • To improve the quality of reports for monthly audits. Clear report analysis of poor performing cold store units.
