Meet the Most Advanced Carbon Cleaning Technology by H2E

H2E Apex decarbonisation machines lineup is our standard one, but is in no means inferior - it simply works great. Apex machines clean the engine while it’s running - hydrogen and oxygen gas (H2E) is mixed with the air in the intake manifold of the engine. Once the vehicle parameters are entered, the app itself calculates the exact amount of gas necessary and the duration of the entire procedure. Simply put, our machine does all the “heavy lifting”, while the operator is present to make sure everything is running smoothly.

Complete Intelligent Cleaning Platform - H2E Ultra!

H2E Ultra is our final, production-ready engine decarbonisation machine for all engines up to 16000ccm, or up to 32000ccm with HD option. The machine is designed for every engine – from the smallest, in motorcycles, to those of heavy-duty trucks, power generators, heavy machinery, and biogas plants. But this is not only the most advanced machine lineup in our offer, we can safely say, it’s the most advanced one in the entire world! And we have a ton of studies, real-world data, and first-hand experience to back it up.

Our Ultra machines feature:
  • Ultrasound technology within the electrolyzer itself - H2E Ultra decarbonisation machines use ultrasound within the electrolyzers to enhance the quality and quantity of H2 gas.
  • Comprehensive external components cleaning - our lineup will soon include ultrasonic baths, "H2E UltraSonic," which were in development for the past 30 years, specifically designed to clean critical components such as EGR valve, intake manifold, DPF module, Turbochargers and injectors.
  • Smart mobile integration - our seamless technology means the machines are able to “communicate” directly with the operator via a mobile app, offering self-diagnostics, calibration tools, and, before long, AI-powered alerts for optimal performance and maintenance.

H2E Ultra lineup is an evolution – but evolution in a different direction. We did not develop these machines to compete with our starting lineup – Apex machines. Quite the contrary – H2E Apex machines perform regular preventative decarbonisation treatments for road vehicle engines; while the H2E Ultra (HD) provides professional decarbonisation, but not only for the road vehicles, but all engines up to 16000 (32000) ccm, while the H2E UltraSonic cleans everything that the engine itself, with the help of H2E gas, cannot clean.

H2E Engine Decarbonization
Benefits

H2E engine decarbonization is the simplest and most effective service for cleaning the compression chamber and exhaust manifold. Restore your engine’s performance by injecting the precise amount of H2E® gas into the engine's air intake. The recovery of engine performance and efficiency to near factory condition has been confirmed through extensive measurements of power output and exhaust gases, conducted before and after the H2E treatment.
  • Restores Engine Performance
  • Reduces Fuel Consumption
  • Lowers Exhaust Emissions
  • Cleans Engine Components
  • Prevents Carbon Buildup
  • Chemical-Free Process
