eJCX Premium Efficiency System

Process Water Filtration for Industrial Applications

LAKOS eJCX Systems keep cooling tower basins free of suspended solids that cause scale, corrosion, fouling and biological activity. Controlling these factors leads to lower maintenance, improved chemical effectiveness, longer cooling tower and downstream equipment life, and a significant decrease in long-term water and energy costs.

  • Premium efficiency centrifugal filtration, independently tested, rated to remove up to 98% of solids 44 microns and larger in a single pass, and 99% of solids 25 microns and larger in recirculating applications.
  • eJCX Systems feature LAKOS eJPX Centrifugal Separator, Premium Efficiency pump, higher capacity (12 liters) Solids Recovery Vessel and/or Fail-Safe Automated Purge valve.
  • Minimize tower nozzle clogging, protect basin floor from under-deposit corrosion, eliminate risk of injury associated with manual basin cleaning, and greatly reduce heat transfer loss in downstream equipment

Basin Sweeping Flow Range: 110 – 1110 U.S. GPM (25 – 252 m3/hr)
Side Stream Flow Range: 140 – 1110 U.S. GPM (32 – 252 m3/hr)
Filtration level: removes fine solids 25 microns and larger

Why Does My Cooling Water Need Filtration?

Cooling Tower High Efficiency
Cooling Tower

Suspended solids clog tower nozzles and water distribution systems – resulting in loss of thermal capacity as well as scale and mineral buildup on tower fill and closed tower coils.

Condenser Tube TCX-TCI
Condenser Tube

Suspended solids reduce heat transfer areas and decrease flow inside tubes by accumulating on internal tube fins.

Heat Exchanger Plate

Solids in cooling tower water clog channels and create areas of low thermal conductivity.

Eliminate Basin Cleaning

High Efficiency Basin Sweeping

Traditional side stream filtration systems take a percentage of the flow (generally 10-25% or less) from the main line using a by-pass directly to the filtration system. The filtered water is then returned to the main line. Basin sweeping is simply relocating the traditional side stream filtration system from the main line directly to the cooling tower basin, thus increasing the percentage of side stream filtration to 20% or more.

Additional advantage is gained by recirculating the filtered water through a network of pipes and nozzles that sweep and direct other settled and suspended solids from the basin towards the filtration system – and away from the condenser water pump.

Basin sweeping capacity is determined by the volume of water in the basin rather than assigning a percentage of the full flow, as is commonly done with traditional side stream applications.

High Efficiency Basin Sweeping

Economical Side-Stream Filtration

High Efficiency Side Stream Cleaning

Using a LAKOS System in Side Stream applications helps reduce suspended solids in mainstream flow, there by reducing downstream heat transfer loss.

Features and benefits:

  • Economical filtration solution
  • Large or variable flow application where full flow is not an option and basins are not accessible
  • Reduce suspended solids in mainstream flow
  • Easy to retrofit
Maintain Closed Loop Efficiencies

High Efficiency Closed Loop Filtration

Using a LAKOS System for closed loop filtration provides 24/7 filtration with zero system downtime, consistent pressure loss and no backwash requirements. Removing dirt, scale, rust and other suspended solids from closed loop systems helps maintain system design efficiencies.

Features and benefits:

  • Remove solids generated in closed loops (chiller water/propylene/ethylene glycol) by using side stream filtration
  • Zero liquid loss when using a Solids Recovery Vessel (SRV)
  • Direct replacement for side stream bags or spiral wound cartridges

Frequently Asked Questions

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 98% of particles 74 microns (0.0029 inches) and larger. Appreciable quantities of particles finer than 74 microns 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.

Contact LAKOS for assistance determining performance expectations on your specific application.

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.
