Fouling costs include cost borne from energy inefficiency, loss of production capacity and the cost related to the cleaning interruptions. The total fouling costs will be minimized when Eqobrush is applied as fouling does not get a chance to affect the tubes in the equipment.
You will get efficient and thoughtful service from FUYI BRUSH.
Eliminate scheduled downtime for tube cleaning with the automatic and online cleaning system. As tube corrosion does not get a chance, also unscheduled downtime for repair or blocking leaking tubes will be a problem of the past.
The unpleasant and environmental unfriendly cleanings are no longer necessary and translate in savings of time and money in labor or chemicals cost and fees for the discharge of cleaning chemicals.
In contrary to the alternative ball cleaning system, Eqobrush cleans ALL the tubes on each and every cleaning cycle. Also, there is no loss of effectivity over time as the brushes have a retention rate of 100%.
Read an extensive comparison of brush vs ball cleaning in the following article.
No more premature equipment replacement due to heat transfer efficiency loss caused by leaking tubes (from corrosion) that have been blocked.
Chiller compressors lifespan is extended as the compressor is running at a lower overall capacity level.
The unpleasant and environmental unfriendly cleanings are no longer necessary and translate in savings of time and money in labor or chemicals cost and fees for the discharge of cleaning chemicals.
Better heat transfer leads to a lower approach which can save up to 30% in energy efficiency. In building operations, this translates into double-digit savings on the total electricity bill! The savings on electricity allow translate into a typical payback time of less than a year on your Eqobrush investment and the accumulated savings over the lifespan of the chiller exceed the replacement value of your chiller by far.
A 10% reduction in flow surface (caused by 1mm scaling layer in a 25 mm tube) will increase pressure drop which in turn requires 30% more pump energy (cubic law) to overcome. Alternatively, this means a lower flow rate which adds to the speed of heat transfer and overall system performance.
The fouling factor that is commonly considered in system design (between 25-100% of added heat exchange surface) can be omitted since the fouling will no longer occur. Smaller units mean less CAPEX.
The discard of chemicals is a burden for the environment that should be minimized. Eqobrush makes further chemical cleanings obsolete, which means no more waste chemicals.
The scaling will no longer affect the tubes which means that the cycle of concentration (of minerals) in the cooling water can be increased and cooling tower blowdown may be reduced by approximately 25%.

Eqobrush tube cleaning system is recognized as an environmentally friendly technology by amongst others the Singapore Green Building Council who awarded it with its highest possible accreditation. This qualifies Eqobrush as a world-class leader in the field of energy-saving on chillers. Read more about the award.
EQOBRUSH now a Singapore Green Building ProductOnce EQOBRUSH system is installed and running smoothly every 4 hours there will be an automatic cleaning cycle. It doesn't require any maintenance other than an annual routine inspection. Brushes have a 100% retention rate and a lifespan of 3-5 years.
Reverse the water flow to the condenser via the patented reversal valve and propel the brushes up and down the tubes using the power of the water. The electric actuator runs but a few hours (accumulated) per year and does not wear and tear. The energy uptake of the Eqobrush system is just a few dozens of kWh annually.
The nylon brushes that go through the tube powered by the water flow are absolutely harmless to the tubes of the heat exchanger or condenser. Tough enough to remove the fouling and scaling (before crystallization sets in) but gentle enough to leave the (copper) tubes intact. Compare it to the effect of the toothbrush on the enamel of your teeth.
The robustly constructed valve will outlive your chiller or condenser and depending on the fouling level of the cooling tower water the brushes will last 3-5 years until replacement.

When removing light scale, a turbo brush may be the best solution. Available in several brush profiles, a turbo brush is unique due to the silicon carbide particles embedded in its bristles. When selecting a turbo brush, it is important to select a brush slightly larger in diameter than your tube ID in order to maximize the cleaning action. By sizing the brush slightly larger than the tube ID, it allows the silicon carbide particles in the bristles to fully come into contact with a larger surface area of the tube wall. This unique feature enhances the cleaning ability of the Turbo brush.
To remove medium scale deposits from a tube, we recommend the use of a descaler tool used in conjunction with a rotary brush. The descaler tool will remove a majority of the deposit from the tube, thus, allowing a brush to pass through afterwards. The brush will then remove the remaining light deposit particles, as well as, polish the inside of the tube. If you attempt to clean this type of deposit with a brush alone, it may encounter deposit obstructions and not be able to pass through the tube. It is important to first remove a heavy deposit with a descaler tool and follow it by a brush to ensure the tube achieves an optimal level of heat transfer performance.
In cases of light mud deposits, a nylon brush would be the best solution. Where the turbo brush needs to be sized larger than the tube ID, a nylon brush should be sized as close to the tube ID as possible. This is because the effectiveness of the nylon brush is in the action of the bristle tips passing across the tube ID. If the brush is oversized, the tips of the bristles will fold over, preventing the brush from cleaning the tube wall properly.
Overall, rotary tube cleaners are a good, economical method for cleaning chillers, condensers, and other types of heat exchangers. Determining the deposit type in your tubes is critical to achieving the maximum cleaning ability of the rotary brush. Once the deposit is determined, selection of the brushes required for the job will be easily achieved. Certain styles of brushes have specific requirements in order to achieve optimal results. Following these tips and tricks will help you regain 'like new' heat transfer efficiencies when using a rotary tube cleaner.
