THERMAL STORAGE SYSTEMS

Series "Trieste"

Thermal Storage Systems

Heat storage systems designed and specialized in hot/overheated water district heating networks made-up of 1 to 8 tanks in parallel. Up to 250 m³ capacity tanks are transportable, even if as special cargo. Beyond this limit they will be built on site. The system comes complete with shut-off valves, control and safety devices, as well as the electrical control panel, regulation, monitoring and data transmission, including provision for remote control and integration on the supervisory systems via existing free and unified protocols.
The most appropriate application, and above all most useful, happens to be in systems where it is advisable or even necessary to stabilize power peaks and use the energy produced in off-peak hours to be used during full peak ones.
