🔹 Emergency/stand-by for critical loads (IT, telecoms, pumps)
🔹 Temporary back-up during outages or scheduled maintenance
🔹 Events / temporary facilities with limited runtime
🔹 Emergency power supply for smaller buildings
🔹 Alternative to diesel gensets in back-up scenarios (not for continuous/prime use)
THE AQUASTROKE 35 kW EMERGENCY/STAND-BY
The AquaStroke® 35 kW is an emergency/stand-by generator that runs on a unique fuel mix of 70% water and 30% (bio)-ethanol. The model is SCIOS-classified (≤500 operating hours per year) and is designed to provide reliable back-up during outages or planned maintenance, with relatively low emissions and no diesel odour/soot.

Advantages Compared to Diesel
✅ Lower emissions compared to conventional diesel generators*
✅ No visible soot / no diesel smell*
✅ Relatively quiet (acoustically insulated enclosure)
✅ Lower operational load (maintenance, filters)
✅ Mobile deployment for back-up scenarios (stand-by)
* Based on manufacturer data; independent EU validation/report is forthcoming / available on request.
Advanced Technology – Tested in Practice
The technology behind AquaStroke® was developed in the United States and is being used there in leading pilot projects. In Europe, the technology is currently in the final validation and certification phase. For the 35 kW version, a CE Declaration of Conformity is available; additional European approvals and documentation will follow.
The 35 kW version described here is an emergency/stand-by model (SCIOS, ≤ 500 operating hours/year) and is not intended for prime power or peak-shaving. Technical specifications may be updated following this European validation..
Independent emission testing to European standards is being prepared. Based on internal U.S. test results, MayMaan has previously reported impressively low emission values—without visible soot and with combustion temperatures below the 900 °C NOx threshold. These values are currently being further evaluated.
