NEW GAS BLENDER MIXES SHIELDING GASES ON SITE
Instrument Reduces Production Costs, Enhances Quality

November 18, 2007 Virginia Beach, VA CONCOA  has introduced a new, easy-to-use blender that enables users to create precise custom-blended gas mixtures on site for GMAW (MIG) industrial welding applications. A CONCOA gas blending system will increase productivity by eliminating time-consuming cylinder handling.

The BlendMaster™ 655 Series is designed to provide 0-10% blend adjustability for argon-oxygen gases. Utilizing pure argon and oxygen, the BlendMaster enhances quality by maintaining a +/- .5% accuracy eliminating the hassle of stratified high-pressure cylinders in storage.

EquiBlend™ technology allows for full flow regardless of the mix or blend ratio, a contrast to fixed-orifice technology.  Balanced stem seat inlet regulators minimize inlet pressure fluctuations to stabilize the mix. The BlendMaster 655 is also compatible with a wide variety of cryogenic supply sources, such as liquid cans, micro-bulk and bulk gas supply systems.  The low inlet pressure range allows for accurate mixing even while supply sources are filled.  Additionally, an optional low pressure remote alarm can be integrated with other building systems via contact interface to provide a higher level of systems integration.  

The BlendMaster 655, available as either a wall- or floor-mounted unit for installation and maintenance flexibility, provides up to 850 SCFH at delivery pressures from 10 to 45 PSIG.  A lockable enclosure assures process control, and an integral line regulator supports flowmeters, regulators, and flowmeter installations. Other options include a continuous binary analyzer for single or multiple gas types. Power requirements are 100 to 220 VAC, and ambient atmosphere and gas supply temperature requirements are 32°F to 100°F (0° to 38°C).
