Predictive Maintenance

Checking: Compressor



Do you want to have a realtime dashboard and tracking of all wagons? 

Do you want to know if a train has to reduce its speed in relation to its load?

Do you want to have automated temperature documentation in all passenger wagons?

Do you want to plan maintenance and be warned in advance if a AC is about to fail?


We offer automatic data capture of all relevant data as well as intelligent predictive maintenance. 

We provide a real time dashboard, with prioritised maintenance notifications and send you alerts and create status reports.

The TrainGuard system Analyse passing trains calculating optimal speeds and send Instant alerts if a train is straining the railroad over its limit in relation to its speed or load. 


TrainGuard - Intelligent Monitoring

for Train Air Conditioning Systems 

TrainGuard is Synap IoT's platform for real-time tracking of passenger wagons and trains, documentation of the temperature in the wagons and monitoring of  the air conditioning systems.

Thanks to Predictive Maintenance and Machine Learning, you will receive an immediate notification if there is a risk that one of your cooling units should fail within the next 2-4 weeks depending on the diagnosis. TrainGuard can detect compressor failures or even coolant leakage at a very early stage.

   Precision range

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

    Optional: + 100°C to -100°C)

Temperature Compliance

Do you want to eliminate manual temperature logging while increasing your compliance?

We automate the logging process and create reports. Your documentation and all compliance documentation is stored completely, securely and GxP compliant in the cloud.

Optimal relation between Load & Speed

Using real-time sensor data, machine learning and artificial intelligence, the state of the rails, the load and environmental conditions are put into relation and speed recommendations for each individual train are determined. 


Automatic Temperature documentation

FDA, CFR 21 Part 11 & GxP compliant

Notification of temperature deviations

Patented predictive maintenance algorithm

NB-IoT, 4G, 3G and GPRS transmission



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 Azure 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

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.



One dashboard that shows the data and the status of all AC-systems regardless of the supplier.


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

Temperature deviation alarm (static and dynamic thresholds)

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. 



Plug & Play Connection: Narrowband-IoT

The application areas of IoT (Internet of Things) are almost unlimited. The requirements pose great challenges for the underlying mobile communication technology. The new transmission technology NarrowBand-IoT (NB-IoT) is ideal for IoT applications that exchange only small amounts of data. We have decided to deploy and use this technology for the following reasons.


Internationally standardised and reliable technology


3GPP LTE security mechanisms, offering a very high security level 


Network coverage over a very long distance possible


Designed for optimized energy consumption


No maintenance and reliable

Azure SynCore IoT Central
SynapIoT offers with SynCore a stable infrastructure, which enables us together with our customers and partners to connect all sensors and to aggregate the information with algorithms, display it in the dashboard and derive direct recommendations for action.

Easy integration 
SynLab IoT connects devices and sensors across multiple protocols, OEMs and standards, we merge data streams, optimize captured data for relevance and context - and we display them intuitively - just as you wish.

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. 

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 monthly for the service and a setup fee.
