LEMAG LEHMANN & MICHELS has manufactured performance measuring instruments for the marine industry since 1911. Today’s product range includes state-of-the-art systems to monitor engine efficiency.
The market-leading LEMAG PREMET® system enables measurement of the power produced inside the cylinder and the LEMAG Shaftpower® system permanently monitors the effective power transmitted to the propeller. The latest addition is the LEMAG SEEAmag® Ship Energy Efficiency Analyzer which measures, records and analyzes key data to help evaluate total ship performance.
LEMAG LEHMANN & MICHELS also specializes in fuel systems. These systems include LEMAG CONTROLmag®, automatic control in fuel change-over systems, the type-approved LEMAG®FQI homogenizer for fuel quality improvement and the LEMAG Slashpol® E water-in-fuel emulsifier for NOx reduction.
PREMET® electronic indicators are designed and manufactured for diesel and gas applications in the marine market and mobile / stationary power stations. These systems are designed for use with heavy fuel oil.
Real-time measurements are possible without stopping the engine to install sensors.
PREMET® C-XL MIPThe PREMET® C-XL MIP measuring system is an extremely robust and simple handheld instrument. This unit displays the course of pressure directly after a measurement has been taken and can store hundreds of measurements along with related engine data. The PREMET® product range includes online systems that enable 24/7 cylinder pressure monitoring.
LEMAG Shaftpower® is a permanently installed power measuring system that measures the actual power output of a ship’s propulsion engine.
LEMAG SEEAmag® monitors the shaftpower, fuel consumption and further key data to enable in-depth analysis and fleet comparisons. The system also constantly analyzes KPIs i.e. M/E, trim, hull or T/C efficiency and displays the results in green, yellow or red for a fast overview.
The LEMAG Slashpol® E can reduce NOx and particle emissions by adding water to the fuel oil. The emulsifier creates a homogeneous water-in-fuel emulsion with an average droplet size of approx. 5 µm, which enables emissions to be reduced across the engine’s operating range. To ensure the LEMAG Slashpol® E reaches its maximum potential, tests are run in the LEMAG laboratory using many different types of fuels and emulsions.
