GE Compatible

AU200-C40+LMB

Heat Capacity: 7.0 MHU Equivalent

Key Liquid Metal Bearing (LMB) Benefits:

Zero Mechanical Wear: Eliminates ball-bearing friction for significantly extended tube lifespans.
Continuous Heat Dissipation: Liquid metal conducts heat rapidly away from the anode, minimizing cool-down wait times.
Near-Silent Operation: Dramatically reduces operational noise during high-speed rotation cycles.
