Static Mixers promote composition and temperature uniformity by increasing turbulence while keeping pressure loss very low. The LPD Static Mixer consists of a series of baffles or “elements” discriminately positioned in series. Each element is comprised of a pair of semi-elliptical plates set 90 degrees to each other. The next element is rotated 90 degrees about the central axis with respect to the previous baffle set, so on and so forth. The LLPD Model, with plates oriented 120 degrees relative to each other, is designed for even lower pressure drop. As the fluid moves through each LPD or LLPD element, flow is continuously split into layers and rotated in alternating clockwise and counterclockwise directions. This method of subdividing the stream and generating striations leads to highly efficient and repeatable mixing with minimal pressure loss. During turbulent flow, the baffles enhance the random motion of molecules and formation of eddies. Component streams are pre-combined upstream of the Static Mixer; alternatively, the minor component(s) may be injected into the main flow through a port near the mixer inlet. The LPD and LLPD are simple-to-install, heavy-duty devices that can produce very uniform mixtures within a short length of pipe. When used in conjunction with automated instrumentation, these mixers deliver predictable quality control based on a virtually maintenance-free operation.
