CTS Fuel Recirculation Unit
Keep your fuel diesel bug sludge free with the CTS Fuel Recirculation Unit, as part of your fuel maintenance programme.
Due to the hygroscopic nature of diesel, water contamination and diesel bug sludge is becoming more and more a problem for the fuel industry.
Conventional fuel tank filters play a role in removing some of the water, but fuel filters alone do not provide a full solution, particularly for fuel that remains in a fuel tank for long periods of times. With our leading industry knowledge, we developed the CTS Fuel Recirculation Unit to effectively address this issue and provide a fuel maintenance solution to prevent the dreaded sludge!
Preventing stagnant fuel in low usage tanks
Fuel that remains in a tank for extended periods can develop diesel bug, which can lead to expensive machinery downtime. To avoid fuel stagnation, storage tanks need proper upkeep, such as regular fuel turnover and filtration to mitigate the risks of water contamination.
Our CTS Fuel Recirculation Unit effectively addresses this issue, keeping the diesel bugs at bay. Make it a key part of your fuel maintenance programme to filter fuel, stop diesel bug and protect equipment, on your generator back up tanks, seasonal refuelling tanks and emergency fuel tanks.
How does the CTS Fuel Recirculation Unit work?
The CTS Fuel Recirculation Unit is engineered to keep fuel from becoming stagnant and to prevent fuel contaminants like diesel bug from forming by circulating 1.5x the contents of the tank every 28 days which is the time it takes diesel bug to grow. It pulls fuel from the tank through a magnetic conditioner, which neutralises the diesel bug, breaking them down into smaller particles that can fit through traditional fuel tank filters.
These particles then pass through a two-stage filtration process that removes water and impurities. The purified fuel is then recirculated back into the storage tank, preventing the formation of harmful sludge that can damage equipment and cause generator or engine failures.

What are the benefits of the CTS Fuel Recirculation Unit?
- Magnetic fuel conditioner and two-stage filtration: 30 micron water & 5 micron particle filter
- Flow switch detects when a filters get full and fuel cannot pass through it, turning off the pump until the filter is replaced.
- Control panel has large, coloured lights for diagnosing a filter blockage, low level or fault scenario, with two output connections for remote warning.
- Fuel tank alarm and fuel gauge input, so that if connected the device can turn the pump off when there is a low fuel level detected to prevent dry running damage.
- Input for probe for a drip tray to indicate leaks.
- Versions for 40,000l & 70,000l tanks
