The GH Group offers an entire range of
modern, high frequency power supplies
and equipment for induction heating
applications, from MF IGBT inverters to HF
Mosfet inverters.
The high frequency power supply and
equipment is used for induction heating
applications, from 3-3,000kW output power
and 0.5 to 400kHz frequency.
In the area of tube induction welding,
which often requires frequencies up
to 500kHz, the natural, most reliable
and efficient component is the Mosfet
transistor. This technology is provided
by GH Group’s latest developments in
variable frequency and automatic load
adjustment.
The company has launched
TransithermicTM generator solid-state
welders, which can weld any tube
specifications, allowing for any tube
diameter, thickness and material.
GH Group serves a range of customers
including a large number of major car
manufacturers and global tier 1 suppliers.
Other applications include continuous pipe
welding, wire heating, home appliances,
and brazing.
