eJCX High Efficiency System

Answer: As a rule of thumb, LAKOS uses a sizing factor of 1 GPM per square foot of basin area to determine the required size of a Tower Clean (TC) system. Using this factor, multiply the square footage of the cooling tower basin (L x W) by 1 GPM / sq. ft. This gives the basic flow rate for sizing the TC system. Tower Clean literature LS-710 can also be used as a reference for more information and equipment selections.

For industrial applications or very heavy solids loadings, consult LAKOS for recommended basin sweeping flow rates.

Answer: LAKOS factory-built purge controllers (ABV, ABV2, AKE, APP, AFS, EFS) do not have factory-set timings. The required purge frequency and durations vary depending on flow rates, solids concentrations, type of solids, etc. The controller time settings must be set at installation and LAKOS literature LS-608 can be used to help establish purge duration and frequency based on the application.

Answer: To determine the necessary purge frequency, purge often at first and calculate the proper rate based on the expected volume of separated solids. Purge duration should be long enough to evacuate the purge chamber AND clear the entire length of the purge piping of all solids. This is usually indicated by a change in the color of the purged liquid from dark to light.

The time between purges should never exceed the time it takes to fill 1/3 of the collection chamber volume, based on the expected solids load and the separator’s purge collection volume, as indicated in the separator’s literature. Refer to LS-608 for additional information on calculating purge frequency and duration.

Answer: While there are many LAKOS Separators still in service after 15-25 years, there are many variables to the longevity of a LAKOS Separator. It can generally be expected to last as long as any other materials of similar construction in that system. Environment, fluid chemical make-up, flow, the material of construction, type of solids, and maintenance purging are all important factors to the life of a separator. It is important to consider all these factors when purchasing a separator. Providing LAKOS with details about your application will ensure your separator meets or exceeds the life expected through your purchase. Consult your LAKOS factory representative to obtain the life expectancy in your specific application.

Answer: Solids-removal efficiency is affected by several factors, including the difference in specific gravity between the solids and the carrying liquid, the viscosity of the liquid, the particle shape, and any purging enhancement techniques. In general, with a specific gravity ratio of 2.6 (e.g. quartz sand in freshwater), liquids of 31 SSU viscosity, and generally round particles, a single pass through a separator predictably removes up to 98% of particles 74 microns (0.0029 inches) and larger. Up to 98% of particles 44 micron and larger for eSeries (eHTX and eJPX) Separators. Appreciable quantities of particles finer than 44 microns (for eSeries Separators) are also removed, as well as particles of lighter specific gravity. Higher specific gravities (like mill scale in water, where SG=5.7) result in much finer levels of filtration.

Recirculating systems (running the fluid through one or more separators continuously) can also result in appreciable removal of particles down as fine as 5 microns.

Answer: As a standard, most separators are available in mild carbon steel and 304L/316L-series stainless steels. Specially designed separators can also be constructed in most weldable metals, including, but not limited to: super duplex stainless steels, chrome-moly, titanium, Hastelloy, nickel alloys, and cupronickel. In special cases, separators can also be fabricated in plastic or fiberglass. For materials other than carbon and stainless steel, consult with LAKOS on the availability of your specific material requirements.

Answer: Yes, we can manufacture a separator with a Canadian Registration Number (CRN). We must know the Province or Territory the vessel is to be located so we can contact the registration controlling agency within that Province or Territory to determine the cost and lead time.
