The turbulent flow created by the economizer part results in:
o Reduced soot deposition – giving a self-cleaning effect
o Increased heat transfer
The Ecolencer requires less space in the casing/funnel compared to the standalone
economizer and silencer.
Approximately 30% shorter and 40-50% weight reduction of economizer part compared to
As a result, this also reduces the amount of steel outfitting in the casing.
Custom-made to meet the Customers` requirements.
The improved design of the economizer part will utilize more exhaust heat at a lower volume.
Designed to reduce thermal stress for the complete unit.
DNV approved integrated spark arrestor.
Control system with touch panel HMI.
Focus on noise attenuation at both high and low frequencies, especially with a focus on a low
frequency contrary to a traditional silencer.
The Ecolencer will help meet the coming strict harbour noise requirements.
- DNV Quiet notation which focus on assessing airborne noise emitted from vessels when
berthed. The Quiet notation gives firm definitions of low frequency noise, distance
corrections and environmental noise correction.
- ESI (Environmental Shipping Index). Vessels can get incentives for the use of ESI noise.
The total air noise score emitted by the ship is the weighted sum of:
o The found sound power level of the broadband noise in dB(A)
o The sound power level in the frequencies lower or equal to 160Hz in dB(A)
o The presence of a noise measurement report.
