Does your bus sometimes have trouble starting?

Does your coach emit excessive amounts of black smoke?

Have you noticed a decrease in your coach’s performance?

Lags in acceleration?

Is your bus getting poor gas mileage?

Are some of the indicator lights on your dashboard lit up?

Are you having (pollution-related) control technology issues?

What is the cause in 75% of cases? A carbon clogged engine. 


Why is descaling a must for buses and coaches ?

FlexFuel Energy Development has designed a descaling and cleaning station for bus and coach engines using hydrogen injection, for up to 9-liter engines: Hy-Calamine 2000S with EGR Pilot option.

The most common cases of clogged engines can be found in the buses and coaches that drive through our towns and spend their entire lives in backed-up traffic. Diesel engines need to reach a certain temperature to be able to achieve complete combustion, but do not always do so and become clogged as mileage increases, which can lead to engine failure, overheating and issues to do with carbon emission deposits on the most sensitive parts of the engine. The combustion that takes place at the heart of your bus or coach engine causes soot deposits inside the cylinders, the pistons, the DPF, the EGR valve and the turbo.

Who hasn’t experienced issues with their diesel exhaust system such as failure or malfunctioning which then affect the DPF causing it to crack?

Once parts are clogged they keep the engine from functioning properly. If carbon emissions (soot) are not eliminated on a regular basis, malfunctions start to occur and add up quickly. A truck full of your cargo could be stuck by the side of the road, not to mention how much parts like a clogged truck injector, a jammed turbo, etc. cost (the turbo will run you approximately 1,350 Euros, and the DPF up to 6,000 Euros).

How is a Hy-Calamine 2000S station relevant ?

Hy-Calamine technology offers a unique and patented solution for handling the clogged engines of buses and coaches in our towns and on our streets; this solution has been certified by the Ministry of Transportation and the Bureaux Veritas S.A.

Derived from the industrial sector and having received media recognition for being extremely reliable, Hy-Calamine 2000S thoroughly cleans engines with calamine build up by injecting hydrogen into the air intake.

Station de décalaminage 2000s

Allowing hydrogen to take its course in this manner will guarantee the regeneration of all of your engine’s components (clogged DPF, EGR valve, turbo and injector). Once regenerated, your engine will regain its drive torque, malfunctions will be fixed and toxic emissions will be reduced by over 50%.

The hydrogen injection descaling Hy-Calamine 2000S station will deep clean your engine including all parts affected by carbon emission build ups. If you have your coach descaled on a regular basis you will avoid the following:

  • Black smoke coming from your truck’s exhaust pipe.
  • Issues with your bus having a clogged DPF.
  • Issues related to poor vaporization on the part of your injectors.
  • Lit engine lights on your dashboard.
  • Loss of your coach’s engine power.

Feel free to visit our Hy-Service website or contact us for more information on how to make your vehicle fleet pollution-free thanks to our intervention teams who will come on-site to clean up your fleet at a time that is most convenient for you.

Our service van can clean up to 6 cars or 3 buses/coaches at a time.

Why opt for hydrogen descaling over the use of chemicals?

The hydrogen descaling process is based on the improvement of a natural phenomenon, that of enriching the air/fuel mixture in your combustion engine.

Descaling can be part of your effort to reduce the carbon footprint your business leaves behind.

Depolluting an engine with chemical products that are pollutants themselves does not make sense if the end goal is to be eco-friendly!

Our process is effective and non-aggressive as it does not use any chemical or corrosive products on your engine.

Carbon emissions in your engine are simply dissolved and naturally expelled along with the exhaust gases, and then effectively collected by a filter.

It is not a good idea to use a chemical product on a 4,000 Euro injection system if you don’t know it’s side effects […] Opt for professional descaling to get rid of buildup safely and cleanly.
