Case Study

Singapore is working towards being a smart nation with the help of Pfannenberg.

4 parties, 3 months of technical discussions, 6 months of testing and 9 months on installations, Pfannenberg takes advantage of our readily available & proven DTS 3000 cooling units.
Singapore is building the world’s first smart nation system by harnessing technology to the fullest with the aim of improving the lives of their citizens. The Singapore Land Transport Authority is now enhancing the network coverage of their electronic road management system with Pfannenberg, thermal management solution for their transmission stations island wide.


This project involved 4 parties, the consulting company, system integrator, panel builder and thermal management specialist (Pfannenberg). From 2012, we have the initial contact to this project, and to the installation of the last transmission station in 2015 (Q2). Much time were spent to finalise on the technical specification, set-up, trial stations and acceptance test on these outdoor transmission stations, located at the rooftops of residential and commercial buildings operating 24/7.
The prototype test station is essential because this new system is designed for new coverage locations with the plan to replace the existing 15 year old systems. Hence, robust and service friendliness is a must as these new systems as they are meant to last the next 20 years.

How product helped.

Singapore climate is generally characterised as hot (23 °C to 33 °C), high humidity (average is 95 %) and with abundant rainfall. So it is almost always warm and wet throughout the year.
Pfannenberg DTS 3000 series is particularly suitable for this application, with its high IP 56 protection system and low maintenance.
The earlier system supplied by competitors were heavily customised with specially designed cover to achieve the required high IP rating.

Results, return on investment and future plans.

September 1998, Singapore implemented the Electronic Road Pricing (ERP) system to better manage the road traffic situation. Progressively, 1,000 stations were in place for the past decades and more are in the pipelines.

Pfannenberg is now thermal managing the new designed transmission stations of the electronic road management system.

With the smart nation vision, Pfannenberg will not only be serving the nation infrastructure needs. We can be expecting more opportunities in contributing to the building of the smart nation.

This project has also enabled Pfannenberg to tie up with the Singapore government one-stop solution partner, system integrator and panel builder.

Next step.

The vision of Singapore towards being a smart nation has also increased the complexity, capabilities & function of these transmission stations. As these stations will not only be used for managing the Electronic Road Pricing (ERP) system, they will also be used to monitor & transmit information such as road traffic condition, traffic surveillance camera and speed camera etc. The old ERP transmission stations will progressively be replaced with the new system.

Pfannenberg is currently also providing the preventive maintenance to ensure these newly installed transmission stations are functioning effectively & reliably.


Singapore is marching towards being a smart nation and an electronic road management system will be one of the key initiatives to connect the country at all times. The collaboration with our competence partners, took us nearly 3 years, from the day of initial contact to the installation of the last transmission station.
Effective cooling of sensitive equipment in outdoor cabinets, located in a hot and humid environment like Singapore is a constant challenge. Pfannenberg is proud to be able to play a part in the building of a smart nation in Singapore with our DTS 3000 series.
