The demands made on the components in combined heat and power plants (CHP) are increasing. They have to be efficient, long-lasting and, in case of an emergency, must at least fulfill the safety requirements set forth by the Medium Voltage Guideline. Thomas Marterer, Product Manager at RINGFEDER POWER TRANSMISSION, explains how operators of CHPs can find the correct coupling for their plant: The coupling should withstand high temperatures and be neither torsionally too stiff nor too soft.

Maintenance is a key factor determining manufacturers’ success since it ensures preferably smooth operation. At the same time service and repair are significant cost factors. We wanted to get a more detailed picture and started researching. Some of the most relevant findings:

"The challenge to develop a highly flexible coupling is to design a coupling which has a particularly soft characteristic curve", explains Norbert Telaar, Head of Strategic Product Management at RINGFEDER POWER TRANSMISSION, the main task of his team. In the end they developed an innovation in coupling design.
