|
 Optical fiber preform gas systems:
Modularity, reliability and flexibility
To suit each specific requirement, our gas supply equipment has a modular structure, based on a set of detachable sealed compartments :
- MFC, LVC or other evaporation control systems.
- Manual or automatic refill system.
- Liquid storage.
|
Preform gas systems may be delivered for any type of power supply voltage, with CE certification or UL certification. The interface to process controller can meet any customer requirement, including standard I/O’s or many types of field buses.

Accuracy
Each compartment has its own heating and its own control system to accurately compensate for the ambient and liquid temperatures.
The use of Digital Technology allows for a precise control of the gas flow rates.
Maintenance
Qualiflow preform gas systems are designed for intensive industrial use. In addition, all components are easily accessible to allow rapid diagnosis. In-situ gas flow calibration increases up-time and enhances the quality and characteristics of the produced preform.
Mastering vaporization of liquid
Qualiflow has developed efficient solutions to handle liquids like SiCl4, GeCl4, POCl3 or BBr3.

Automated Gas Purifiers for Preform Gas Systems
 |
Impurities such as CH4, CO2 or H2 are found in oxygen and all process gases (freon, chlorine, argon or helium) when manufacturing Optical Fiber preforms. Levels can reach values of up to 10 ppm.
Qualiflow Automated Gas Purifiers purify process gases by reducing the amount of impurities down to 0.2 ppm.
Qualiflow offers very high quality Automated Gas Purifiers designed to dry and purify O2, He, Cl2, N2, Ar and Freon.
Qualiflow Automated Gas Purifiers, ancillary equipment to Qualiflow Gas Systems, will provide the best results regardless of the process used when manufacturing Optical Fiber Preform (MCVD, OVD, PCVD or VAD).
