Maritime diagnosis & service

MARIDIS products provide specific recommendations for technical and economical optimization. Easy use, self-explanatory software, precise measurement results and all relevant data at a single glance: Intelligent simplification that enables high performance at reduced costs, maximum optimization with minimal effort!
Protecting engines, reducing fuel consumption and therefore costs is the ultimate objective of the remote diagnostics based on databanks and of the assessment of the engine status implemented by MARIDIS.


A new generation of cylinder pressure handheld devices.
The MarPrime system is a simple, userfriendly device for measuring cylinder pressure. It is designed to measure and analyse the combustion process of 2 and 4-stroke marine diesel engines and for stationary power plants. It offers the potential to gauge all the engines in your machine room and draw up well-founded diagnostic reports quickly with a high degree of accuracy.

The MarPrime system uses a “high performance electric pressure transducer of well proven design” which allows the cylinder pressure to be measured very accurately. With the MarPrime handheld device you have a “one-hand / one-person” tool which quickly and easily collects and records the full range of engine performance data. An additional feature in the MarPrime Ultra version is the ultrasonic sound sensor. It enables the engine timing such as the start and finish of the injection process and the engine valve timing to be determined very precisely. However, its main function is to determine the leak tightness of the valve unit, which it does by analysing and displaying the sound of the fluid flow at points where leakages occur.
Fast data transfer via a network connection and automatic hand-held device recognition guarantee easy operation when reading out and displaying data.

Using the software supplied the measured pressure sequences can be displayed accurately as a function of the crank angle (no flywheel pick-up or other sensors are necessary).

The measurement information provided can be used to:

- Calibrate engines
- Monitor the load equalisation
- Monitor the timing
- Reduce fuel consumption and emissions
- Determine condition of the cylinder head (and indirectly of piston rings)
- Reduce costs of replacement parts
