Part II Ultrasonic Enhanced Generator |
System Features
|
2.4MHz Ultrasonic Enhanced Generator
304 Stainless Steel 1.5" sanitary TEE fitting with 1/4'' tube fittings enable the use of carrier gas
Fluoropolymer coated liquid container with fluoropolymer seals
Microprocessor based control allows the user program operating parameters (time and the rate at which particles are being generated) into the unit, handling a wide variety of applications for accurate particle generation.
Fluoropolymer optical sensor and Fluoropolymer valve for keeping the liquid level to the correct height and preventing damage to the nebulizing element, should the unit run dry.
The use of quick clamps allows easy removal of components for cleaning or adapting the device with simple connections to gas supply |
Input Voltage |
220VAC |
Ultrasonic Power Setting |
0 to 100% of the full output capability, in 5% increments |
Part III Nanopowder Collection |
High Voltage Supply
|
AC 220V 50/60Hz, 50 W Max. power consumption
Digital Voltmeter and Current meter, 30 kV, 1 mA max.
Output voltage and current can be set on the front panel and read from the digital display
Constant current/Constant Voltage mode of operation
Built-in Arc protection circuit |
Electrostatic Precipitator |
Up to 30 kV and 1 mA.
The use of KF25 enables the quick coupling to the furnace processing tube; |
Part IV Mass flow meter system |
Mass Flow Meter
(touch screen is optional)
|
Three precision mass flow meters :
MFC 1: Gas flow range from 0~500 sccm H2
MFC 2: Gas flow range from 0~1000 sccm N2
MFC 3: Gas flow range from 0~1000 sccm N2
One gas mixing tank is installed on bottom case with liquid release valve
3 stainless steel needle valves is installed on left side of bottom case to control 3 type gases mixing manually. |
Part V Liquid Vaporization System |
Heater & Temperature Controller |
Liquid and carrying gas go through an SS316 coil, which is heated by a built in small furnace up to 550ºC
The heating tube could be generate as secondary heating to prevent the liquid or gas cool down while passing through the tube. |
Gas Flow Control |
Carrying gas (inert gas) is controlled by a precision float flow-meter (200 - 2000 mL/min adjustable).
Pressure gauge built in front panel
Two SS needle valves are installed to control gas in and out .
Vapor Gas outlet tube size: 1/4"OD SS316 |
