Dantherm Air Handling and Dantherm Power have developed the integrated outdoor cabinet solution, which has been chosen for Denmark’s new public safety network - SINE.
The communications system used today by the police, the fire-fighting service and the ambulance service is on average 15 years old. The oldest have been in action for 25 years, and have long ago been overtaken on the inside by new techniques. That is one of the reasons why the Danish Parliament in 2007 agreed on a change of the Danish Preparedness Act which commits all parties of the Danish preparedness to using a completely new common radio communications system.
Another important reason is the peak load problems in connection with terrorism and other emergencies that the international community has experienced in recent years. It appears that the known networks such as the GSM network fail because of stress and too heavy load. Consequently SINE, the Danish public safety network, is based on the newest digital Tetra technology, where the signals always find a way, although some radio stations may be overloaded or inoperative.
450 radio stations with cooling and fuel cell based backup power
Dantherm Air Handling and Dantherm Power have developed an integrated outdoor cabinet solution for the approximately 450 radio stations established all over Denmark in connection with the SINE network being rolled out during 2009. The cabinets contain ventilation and cooling for the advanced radio-electronics, and a hydrogen-based backup power system that instantly takes over if the electricity fails or becomes unstable.
At Dantherm we are proud to deliver the solution to an area which is so important for the society. In Denmark the SINE network will be used by government authorities such as the police as well as regional emergency services such as the ambulance service, fire-fighting service and rescue preparedness. It will be used in everyday work, and it will especially show its advantages when many emergency services work together to save lives in case of major accidents, natural disasters, pollution or in connection with the escape from fire and explosion accidents.
Although the fuel cell based backup power provides significant environmental benefits compared to conventional backup technologies like batteries and diesel generators the decision to use fuel cells is based on purely commercial and technical arguments without any public funding. It provides the SINE-Network with very high reliability and significant lower maintenance and it can ensure the network uptime for a very long undisclosed period.
As far as Dantherm Power is aware this is the first nationwide network in the World with critical sites backed up by fuel cell technology.
Dantherm Air Handling and Dantherm Power expect that the order from the Danish Sine/Tetra network will result in more attention from other countries, who are planning or enlarging similar Tetranetworks, and who are looking for a supplier of such integrated cabinet solutions.
