New Gas Blender Designed for On-Site Mixing



CONCOA has introduced its new blender that is built to enable users to create precise custom-blended gas mixtures on-site for GTAW (TIG) and GMAW (MIG) industrial welding applications.

Designed to increase productivity by eliminating time-consuming cylinder handling, the BlendMaster 657 Series provides 0 to 25% blend adjustability for two-component gases. "Blending pure argon and carbon dioxide gases, the BlendMaster 657 enhances quality by maintaining a +/- 1.5% accuracy and eliminates the hassle of stratified high-pressure cylinders in storage," said a company spokesperson.

According to the company, EquiBlend technology allows for full flow regardless of the mix or blend ratio, a contrast to fixed-orifice technology. A pressure equalization system minimizes inlet pressure fluctuations to stabilize the mix, broadening the inlet pressure range difference between the major and minor component gases. The BlendMaster 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," said a company spokesperson. "Additionally, an optional low-pressure remote alarm can be integrated with other building systems via contact interface to provide a higher level of system integration."

The BlendMaster 657, available as either a wall- or floor-mounted unit for installation and maintenance flexibility, provides up to 1,750 SCFH at delivery pressures from 10 to 50 PSIG. A lockable enclosure is designed to assure 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 110 or 220 VAC, and ambient atmosphere and gas supply temperature requirements are 32 °F to 100 °F (0 °C to 38 °C).
