Batch high-shear mixers equipped with the Solids/Liquid Injection Manifold (SLIM) Technology (photo) deliver powders in an efficient manner for quick wet-out and complete dispersion into low-viscosity liquids. In a conventional rotor/stator mixer, materials are continually drawn from below the mixing head and then expelled at high velocity through the stator openings. A SLIM mixer assembly with Progressive Spiral Porting creates a powerful vacuum that draws powders directly into the high shear zone and rapidly disperses individual solid particles into the liquid vehicle. This method of powder addition dramatically reduces the formation of lumps (fisheyes), prevents floating powders, eliminates dusting, and accelerates mixing time, says the manufacturer. The SLIM can also be used to introduce minor liquid components and create fine emulsions. To easily raise and lower the mixer in and out of the mix vessel, a floor-mounted design equipped with an air/oil hydraulic lift is available. Safety limit switches prevent operation of the mixer while in a raised position or without a mix vessel in place. — Charles Ross & Son Company, Hauppauge, N.Y.

The Titan (photo) is a specific fixed gas detector, based on photoionization detection (PID), designed only for the monitoring of benzene. This makes it the perfect choice for use in asphalt manufacturing plants, where benzene is likely to be the most prominent volatile organic compound (VOC) that requires management and monitoring. As a fixed unit, the Titan can be installed at regular distances around sites, and with its “plug and play” installation approach, the Titan can be left monitoring without the need for intervention. Two alarm systems can be set at the user’s convenience, and another two are pre-set relays for immediate warnings, so no exposure incident is ever missed. The Titan offers continuous real-time data feedback of VOC concentrations in the air, taking samples every minute to an accuracy of 0.1 parts per million (ppm) or +10%, whichever is greater. — Ion Science Ltd., Royston, U.K.
Drain valves comprise up to 20% of all valves in a typical processing plant. But cleaning them is costly, difficult and time-consuming due to long cleaning cycles and the risk of pressure shocks. The new ThinkTop pulse seat clean (photo) addresses all these issues, quickly and effectively cleaning drain valves while delivering savings of up to 95% in cleaning-in-place (CIP) liquid, says the company. Short bursts, or pulses, drive the valve cleaning process, activating the valve when shear forces peak. Each position-based pulse takes less than a second, preventing pressure shocks in the system. The pulse creates high turbulent flow as the liquid passes through the narrow gap between the valve house and valve seat, effectively removing all residuals for spotless drain valves. Intended for use with single-seat valves or butterfly valves used as drain valves, pulse seat clean is a standard feature of ThinkTop V50 and V70 sensing and control units with one solenoid valve. — Alfa Laval AB, Lund, Sweden
