District Heating and Cooling


One of the most energy-efficient methods of transporting hot potable water as well as heating or cooling water covering long distances is the application of underground piping. To achieve the necessary insulating characteristics for this type of application, aquatherm offers the factory made pre-insulated
Ti (Thermal Insulated) pipe system with different medium pipes and fittings.
