Technical Specifications
Installment required measures
Accessory designed to isolate electrical currents in metal pipes,
while offering a large flow rate and resistance to high pressures.
In industrial plants it is desirable to protect measuring and control
instruments, isolating them from electrical currents generated byapplication of cathodic protection, statics current, etc.
The device is specially designed for use in CNG facilities, installed
between the compressor and the storage, transport units and
dispensers.
