ReeferGuard: Full Container Monitoring

Platform for Reefer Containers

ReeferGuard is our plug & play solution for reefer container monitoring and Tracking. With hardware and software developed specifically for the specific needs of the demanding logistics, offshore and shipping industry. ReeferGuard monitors and documents the GPS-position and temperatures in the reefer container and generates automatic reports every two hours, which you can easily access from any device (PC, Mac, Android and IOS). 


If a refrigeration unit is about to malfunction, our predictive maintenance algorithm will notify you up to 2-4 weeks in advance depending on the diagnosis. This valuable tool allows you to better plan service calls.

    Precision range

    +50°C to -50°C (Factory Calibrated)

    Optional: + 100°C to -100°C (TÜV Calibrated)


Upgrade to Reefer 4.0

The SynapIoT ReeferGuard™ infrastructure is a 4.0 upgrade in the way reefer operators work and manage their reefer fleet. For example, if a container sends an alarm message at the end of a long voyage, you can send it to a service technician who will service the compressor or condenser immediately after arrival in port, so that onward transport can be continued without problems or delay. This ongoing self-diagnosis process eliminates the need for expensive PTI (Pre-Trip-Inspection).

You are always in control, you know the GPS position, the temperature in the container, the status of the coolant of each reefer and the live energy consumption.


Temperature Compliance

Do you want to save time and money and eliminate the manual temperature measurement of refrigerators and freezers while increasing your compliance?

We automate the logging, create the reports for the authorities - so that they are digitally available to you every day. Your documentation documents and all compliance documentation are stored completely and securely in the cloud, and always available for your next test visit and set up in accordance with GxP.

All data at a glance

In the intuitive dashboard you have a clear overview of all relevant data. Furthermore you can set different individual static tolerance limits for the sensors of each cooling unit - easily and intuitively - you can and also define the tolerance level of the dynamic thresholds. 


When a predictive maintenance, dynamic alarm is triggered, you will receive an immediate notification in the form of an e-mail and a text message.  


You can select any number of recipients as recipients.  We are currently working on offering you an automated call that reads the error message to you - this will follow in an automatic update soon. 


Predictive maintenance, dynamic and static temperature alerts are standard in our temperature products.

Predictive Maintenance

In the setup phase, we support you in setting the relevant parameters. Our SynCore™ platform, through machine learning and artificial intelligence, gets to know your cooling unit better and better, so that irregularities can be detected earlier and earlier so that a service technician can address the problem to prevent your cooling unit from being damaged or even failing.

We can predict the following possible errors in the cooling system with our predictive and preventive maintenance algorithm

Mechanical controller malfunction

Pressure drop from the refrigerant

Dusty or Clogged condenser

Compressor failure


Machine Learning

The pattern of your cooling unit is continuously analysed through machine learning and predictive maintenance. Irregularities, e.g. in the compressor, can be recognized very early and failures such as Damage to the cooling unit can be prevented by an additional service visit.


The temperature monitoring algorithm continuously checks whether the normal pattern changes in the interior of the cooling unit, e.g. whether the temperature is not properly regulated over a certain period of time and whether the temperature continues to rise and approaches a pre-set critical value.


The combinations of different sensors also enable warnings of the set static tolerance limits if the temperature rises over a longer period of time without the door being open, for example, or if the temperature regulates itself too slowly. We call this: dynamic tolerance. In the Dashboard you can easily and intuitively set different static tolerance limits for each cooling unit and also set the tolerance level of the dynamic threshold values.

Plug & Play

Installation time less than 5 minutes, without any previous knowledge. No need of wifi infrastructure, the unit uses a mobile  connection.


Instant Notifications

Alerts and notifications are send to any number of recipients (via SMS & email).


Lifelong Guarantee

Over-the-air updates, redundant self-diagnosis and lifelong product guarantee


Retrofit to 4.0

Retrofitting is possible on every cooling unit from every OEM. For many cooling units, a 4.0-retrofit can make more sense than a replacement. 


Secure NarrowBand IoT Transmission 

NB-IoT is particularly ideal for many sensors and IoT applications that exchange data only rarely or only sparingly. For these and the following reasons, we at SynapIoT have decided to take advantage of this technology and incorporate it into all of our products.


For most public and private IoT applications, the “narrow” or low bandwidth of Narrow Band IoT is more than sufficient. NB-IoT is also a perfect solution for IoT due to its optimal security of supply and nationwide presence - a much better solution than WLAN or LAN, since these networks are comparatively unstable and sometimes also insecure. The NB-IoT technology uses the secure 3GPP industry standard, it is an internationally recognized, standardized and reliable technology and architecture. 3GPP offers a multi-vendor connectivity, compatibility and secure international coverage.

In addition to the NB-IoT transmission unit, we have also equipped our products with GPRS, 3G and 4G transmission units to ensure that reception is possible everywhere. Furthermore we run automatic firmware updates over-the air.

In our opinion, IoT-Equipment-as-a-Service (IoT-EaaS) is the next step towards a simpler and more advanced usage model. You "rent" our products and services, thus protecting your balance sheet and only burdening your income statement in the correct period. Your accountant will no doubt be happy not to activate and not to write off a depreciation plan, but only to record an expense.

This also means a much more effective way of working, because if you no longer need the sensor, simply send it back to us and then others can benefit from it. This corresponds to the modern and sustainable thinking of our customers and fits our innovative products.

What does that mean for you?

It means that you have to rent the hardware and not buy it - you only pay for the service and a set-up fee.
