Containerized Induction Heating Systems

TESI containerized induction heating system is the answer to the field needs related to welding and coating of field joints in the construction of Oil & Gas pipelines, mainly offshore.
The system consists of DNV 2.7-1 certified containers of 10 ft (3 m) or 20 ft (6 m) in which both operational and backup static generators (inverters), automatic solid state changeover switches for switching from operational to backup, cooling systems and all other components are installed.
To avoid production downtime due to breakdown or maintenance of the induction heating system, it is supplied with backup unit that, thanks to the redundant system, allows to switch from the operating unit to the backup unit quickly and easily.
The parallel output circuit also allows the installation of the induction heating station away from the generator. Special water-cooled or air-cooled coaxial cables, depending by the application, and the use of remote capacitor racks, guarantee the reduction of power transmission losses of the cables themselves and allow the installation of remote induction heating stations even at distances over 50 m.
