Remote Monitoring & Early Fault Diagnostics of equipment


One Smart Platform! 

Advantech & partner’s cloud-based solution, enables cooling tower manufacturer EWK to increase the lifespan of its equipment and considerably reduce service costs


Smart Care for Cooling Towers is one of the most advanced IoT solutions available on the market today. It allows for the remote monitoring and diagnostics of cooling tower assets as well as the measurement of its overall performance and the state of each of its components. Being a cloud-based solution it eliminates the need for numerous hardware devices. This is made possible through the combination of multiple technologies from the following contributors: Ericsson Cloud (IoT Accelerator), SmartLog (Dashboard Solution - AKURU), Advantech’s Smart Edge platform “ECU-& EdgeLink” and a leading telecommunications operator.

The Client 

Spanish based company EWK designs and manufactures cooling towers, evaporative condensers and adiabatic equipment, designed to obtain the highest energy efficiency. Over the years the company has produced and installed tens of thousands of cooling towers across the globe.   

The Challenge 

One of the most frequent challenges for owners of cooling towers is when the system fails, it stops without any warning. Many of EWK’s clients operate 24/7 production facilities and in the event that the system fails, the temperature of this critical process is no longer controlled and stops. This leads to customer dissatisfaction and financial loss due to the stoppage of the production process. Further costs to repair the equipment, as well as penalties from the authorities, may also be incurred. Up until now if a service maintenance contract was not in place, EWK and its service partner had no means of knowing the precise status of its installed equipment until it broke down.

The Solution 

Smart Care enables cooling tower owners and manufacturers to monitor the equipment performance remotely, allowing for the early detection of faulty hardware and in turn the provision of timely service. Through the user-friendly dashboard, the manufacturer can also learn more about the system, stay updated on its performance and in turn provide a highly reliable platform to its customers.   

 “At last, remote controlled cooling towers thanks to the EWK SMART CARE service powered by Advantech.”Javier Vaquero. EWK Equipos de Refrigeración, S.A.  

The Process 

 Advantech’s Smart Edge box “ECU-& EdgeLink” is easily installed to an electrical connection in the Smart Control Cabinet on the cooling tower, it is Modbus TCP. The ECU transmits the Modbus TCP data over the telco network to the Ericsson Cloud IoT Accelerator. The software converts that data from any control system such as data conversion – protocol conversion event handling and logging data which is then translated into user-friendly information that is broadcast on the SmartLog AKURU dashboard. The solution can connect to almost any industrial hardware device and cloud-based platform. In this case, EWK now has instant feedback on the health and performance of each of its towers.

The Outcome 

EWK’s customers can expect a significant uptime on each installed cooling tower with unplanned maintenance activities kept to a minimum. Before this solution, a cooling tower downtime usually led to an unexpected and unwelcome factory stoppage. Therefore, the system requirement is to connect the Cooling Tower information to a central monitoring point.   

“Prevent unplanned maintenance through condition monitoring and transform data into information”, says uptime-engineer Lise Vandeborne of Smartlog

Advantages to the end customer
