OHMEGA Steel Tube Technology

Ohmega Resistors are resistors based on steel tube technology. They can be air cooled or water cooled.

Water cooled resistors can be supplied from a standard line from 5kW to 500kW having protection degree IP00 – IP65.

Air Cooled types can be used in aggressive environments and if high degree of protection is required.

 
OHMEGA OEM Resistor Elements

The Resistor Wire in these elements is mounted in a compressed steel tube and fixed by compressed MgO.
Applications are: Water cooled resistors, High Voltage Snubber Resistors, High Load High Temperature Load Resistors and Air Cooled Resistors in aggressive environments.
