ARTEMIS Dual-Fuel Systems are based on HEINZMANN’s proven gas engine components and powerful actuation and governing units. They ensure a perfect gas-air mixture quality and high conversion ratios. Operating dual-fuel engines with up to 2 MW output, the gas controlled and gas mixer based systems are suitable for stationary applications as well as heavy-duty vehicles.
Gas Admission Valves
MEGASOL is HEINZMANN’s series of electrically actuated gas admission valves. They are intended for gas and dual-fuel operation on industrial turbo charged four-stroke engines. Each cylinder requires one MEGASOL valve. MEGASOL valves ensure proper gas quantity or each cylinder and allow gas flow compensation cylinder for cylinder.
EGASOL Gas Admission Valves
MEGASOL valves are designed to operate with a comparatively high differential pressure of supplying air and gas. They are characterized by excellent load response, precise dosage and individual adjustment of gas quantity for each cylinder. MEGASOL valves have a very low leakage when closed and are easy maintain.
- Precise metering of gas quantity for each cylinder individually
- Fast response and excellent load behaviour of engine
- Suitable for new engines as well as for retrofit solutions
- Available for alternative fuels such as hydrogen or ammonia
- No risk of backfires
