This gas blender eliminates the need for cylinder handling
The BlendMaster 657 Series gas blender enables users to create custom-blended gas mixtures onsite. Designed to increase productivity by eliminating time-consuming cylinder handling, this blender provides 0–25% blend adjustability for two-component gases. Unlike fixed-orifice technology, this blender’s EquiBlend technology allows for full flow regardless of the mix or blend ratio. 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. 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. Ambient atmosphere and gas-supply temperature requirements are 32° to 100°F. — Controls Corp. of America (Concoa), Virginia Beach, Va.
