How does a Chiller Work? In most process cooling applications, a pumping system circulates cool water or a water/glycol solution from the chiller to the process. This cool fluid removes heat from the process and the warm fluid returns to the chiller. The process water is the means by which heat transfers from the process to the chiller.

Learn MoreA picket-fence analogy is often used to explain how this dual-filter demonstration works. A picket fence can act as a polarizer by transforming an unpolarized wave in a rope into a wave that vibrates in a single plane. The spaces between the pickets of the fence will allow vibrations that are parallel to the spacings to pass through while blocking any vibrations that are …
Learn More· A coalescing filter (or simply coalescer) is a filtration system consisting of several baffle walls or screens. A stream of fluid to be separated (, a gas-water mixture) is applied to the filter and the baffles screen out the various components by trapping them in different sections. Thus, the components of interest can be recovered in pure
