A method of treating a device to resist formation and build-up of scale deposits at the device is provided. The device is located in a fluid-containing conduit. The method comprises feeding a radio frequency (RF) signal into a line connected to a device located in a fluid-containing conduit; and propagating the RF signal along the line to the device to resist formation and/or build-up of scale deposits at the device. A system for treating a device to resist formation and build-up of scale deposits at the device is also provided. A signal generator operable to generate an RF signal for treating a device to resist formation and build-up of scale deposits at the device is also provided. The signal generator is operable to feed the RF signal into a line connected to the device and to propagate the RF signal along the line to the device to resist formation and/or build-up of scale deposits at the device.

Method, system and signal generator for treating a device to resist formation and build-up of scale deposits

A fluid treatment apparatus includes a ferrite assembly, a driver, and an oscillator circuit. The ferrite assembly is arranged in use to be capable of surrounding a conduit containing fluid to be acted on. The driver is arranged to generate a pulsed current to which the ferrite assembly is subjected whereby the driver is electromagnetically coupled to the ferrite assembly. The oscillator circuit is electromagnetically coupled to the ferrite assembly, and in response to the pulse generated by the driver, causes an oscillating signal to be generated which gives rise to an electromagnetic field which acts on the fluid in the conduit.

Fluid treatment apparatus

A method and system for injecting a pulsed radio frequency signal into a fluid-containing system in order to create and propagate an electromagnetic field throughout the fluid-containing system. The electromagnetic field may be used to prevent the formation and build-up of scale in the fluid-containing system and/or to prevent the proliferation of bacteria within the fluid-containing system. The method and system may also be used to inject a pulsed radio frequency signal at a number of points in a fluid-containing system, or to inject a pulsed radio frequency signal to a number of independent fluid-containing systems.
