LAKOS - Model eTCX -High Efficiency Tower Clean System
LAKOS Premium Efficiency eTCX Tower Clean 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.
- High efficiency centrifugal filtration, independently tested, rated to remove up to 98% of solids 44 microns and larger in a single pass, and up to 99% of solids 25 microns and larger in recirculating applications.
- eTCX Systems feature LAKOS eHTX Centrifugal Separator, Premium Efficiency pump, higher capacity (12 liters) Solids Recovery Vessel and/or Fail-Safe Automated Purge valve, and SmartStart Control Panel.
- 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: 50 – 910 U.S. GPM (11 – 206 m3/hr)
Side Stream Flow Range: 65 – 810 U.S. GPM (15 – 184 m3/hr)
Filtration level: removes fine solids 25 microns and larger
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
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.
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.
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
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
