Cold Chain Monitoring Case Study: IceConnect Plug & Play sensor

A third of the food produced globally is wasted, with much of that loss occurring along the global cold chain. Overall, that translates to 1.6 billion tons of food, worth about $1.2 trillion, down the chute. While low prices and frequent promotions drive consumers to the store, food quality and freshness is often their biggest concern, making temperature monitoring a critical operation for retailers.


Manage remotely, a large number of refrigerated furnitures throughout the country. Monitor the energy consumption of refrigerators and receive alerts in case of malfunction to ensure compliance with temperature requirements from regulatories.


A cost-efficient, low-power industrial-grade  tracker with a temperature sensor that lasts  for at least 2 years.


• 15% reduction in food waste. 
• New revenue from value-added services. 
• High-quality temperature control and  reporting that meets regulatory guidelines. 

Loca Service is a leading refrigerated furniture rental company headquartered in France that has been providing tailor-made rental service for large and medium-sized retail stores (supermarket and hypermarkets), and food manufacturers in Europe for the last 40 years.

With a network of 12 agencies throughout Europe, Loca Service has a catalogue of over 300 products  and over 38,000 refrigeration displays in circulation,  including the stores of Auchan, Carrefour, Monoprix,  Starbucks, Pepsico and Danone.

As an expert in refrigeration, Loca Service wants to  design a cost-effective and reliable reporting  solution for clients to maintain proper control of their  refrigerators without the need for time-consuming  and costly manual data collection.

Automated readings guarantee specific cooling  conditions, better food preservation and significant savings while complying with strict regulations. 


Refrigeration monitoring is not only a regulatory requirement but a crucial part of F&B operations with real consequences.
Those who have experienced a loss of inventory due to a broken refrigerator, or worse, sold food that was compromised unknowingly, causing food poisoning, can attest to how painful such an experience can be. While the loss of inventory and time (to repair the refrigerators) is temporary, negative publicity and the permanent loss of customers can affect businesses in the long run or even cause them to shut down.

Traditionally, retail stores have refrigerated display cases to keep food such as dairy products, fish, meat or drinks at specific cooling temperatures. The use of these display cases requires multiple daily visits to the fridges (minimum twice a day) to guarantee that the temperature conditions are well maintained. Temperature data are collected and reported manually in Excel sheets, and these data logs are kept in store for at least 12 months in accordance with HACCP standards.

This labour-intensive procedure is not only cumbersome and inefficient but also subjected to human errors. On top of that, they are not performed or accessible during store closing hours.

For retailers, food must be carefully monitored to ensure shelf life and food safety. However, the  quality control of an ever-expanding range of  produce and products are laborious and costly due  to different temperature and handling requirement. 


Hazard Analysis and Critical Control Point (HACCP) is used in the food industry to identify potential food safety hazards, so that key actions, known as Critical Control Points (CCPs) can be created to reduce or eliminate the risks.

HACCP helps F&B industry to put in place an effective integrated food safety management to ensure safety and traceability. The implementation of a Food Safety Management System based on HACCP principles is a legal requirement.


The solution is designed to send location and temperature change data to Loca Services so that their  customers can take swift measures to change fridges or move products if necessary. 

In the event, when the power of the fridge goes below the minimum threshold, a warning will be sent to the  customers by email and in push notification via mobile phone apps to inform their customers of a possible  breakdown. However, should the temperature returns to normal, a second alert will be sent.


Since the implementation of the IoT solution, Loca’s customers receive regular update on their refrigeration assets helping them to:

Reduce loss of perishables by 15%

Monitor energy consumption of equipment

Be alerted when temperature have veered out of their normal ebb and flow via the mobile application, email, or text messages

Improve the management of every rented fridge. e.g. to send malfunctioning refrigerators for repair or replacement

The idea of Ice-Connect came to fruition when we met UnaBiz and IoThink. In order to develop a  high-quality product, we need very high precision components such as the external antenna and  temperature probe. UnaBiz’s R&D team’s expertise in product design and manufacturing allowed us to achieve a highly  customised product within a short time span.
