Thermico CPF2 powder feeder. -

The Thermico CPF2-Powder Feeder can dose and convey different types of powder with high levels of precision.

_- typical standard powder >15µm – plasma-spheroidized carbide powder <15µm and <6µm – plasma-spheroidized oxide-ceramic powder <5µm- _

Enclosed in a cabinet to ensure a dust free environment it can be delivered in different versions for plasma, powder flame and HVOF coating processes.

The CPF2 Powder Feeder works volumetrically with a feeder wheel which measures out the powder precisely into the carrier gas stream and transports it to the spray gun. Together with the integrated weighing unit it becomes a gravimetric conveyor which doses the powder at extremely high levels of precision (±2%).

Minimal dosage amounts for the standard feeder are 5.0 g/min and for the Low Amount Feeder: 0.5 g/min.

The powder containers can be exchanged easily for cleaning and can be fitted with two standard and two special feeder wheels. Four different container volumes can be selected – 0.5 – 3.5 – 5 – 10l -. The powder containers are fitted with one or two vibration units to overcome the poor flow properties of microfine powders <10 μm.

Container and carrier gas heating and vacuum systems protect the powder from becoming damp and avoid any undesirable powder agglomerations. These are available as optional equipment.

The flow of carrier gas is controlled by means of a mass flow regulator to within ±2% of the set values. Deploying the gravimetric regulator by means of feedback control between the weighing unit and wheel feeder also provides for a particularly constant supply of carrier gas and achieves even higher levels of precision.

The CPF2-Powder Feeder from Thermico is available in two versions: as a remote device which is set up for integration in a higher level control system – linked to a PLC or PC via an analog interface or data-bus. Or as a standalone version which has its own control and operating panel with a 7.4” touch screen.
