As the Canadian representative for IOP Marine our core business comprises the development, manufacturing, sale, marketing and maintenance of pneumatic/hydraulic fuel-injection valve test equipment and hydraulic power units for 2- and 4-stroke diesel engines. IOP Marine started manufacturing high pressure products in 1969 and has been developing, improving and enlarging their product range ever since. This is why IOP Marine today is one of the leading suppliers of high pressure products. Engineering and manufacturing of all products is performed in-house at our facilities in Brondby, Denmark, which secures the high product quality for which IOP Marine A/S is known.
When you buy an IOP Marine product, you buy quality equipment that keeps performing for several decades.
Fuel injector test rigs
Our VPU series
For larger 2- and 4-stroke diesel engines it is necessary to test the fuel injectors after a specified amount of running time, to determine the performance of the injector. This includes tests like:
- Verification of Opening Pressure - determine the pressure needed to initiate injection through injector nozzle
- Calibration of Opening Pressure - calibrate/adjust the opening pressure while the injector is under pressure (4-stroke engine injectors only)
- Nozzle Leakage test - make sure nozzle is tight during idle time
- Injector Spray Pattern - inspect direction of jets as well as quality of atomising
- Non-return Valve Functionality
- Tightness of o-rings and seals
- Correct operation of safety valves
And other pressure-related tests for diesel engine fuel injectors and safety valves.

Windows / Mac / Linux connectivity: The test results can be transferred to any type of PC using the built-in USB port and the information can be used electronically as documentation. Test results are transferred as MS Excel files.
VPA Injector Compatibility
The VPA 1100 series is compatible with almost all traditional 2- and 4-stroke fuel injectors (excl. RT-flex, where a VPU 500 is required), and we do today have injector valve holders for more than 150 different injector types. In case you are working with injectors which we do not have in our programme, we will forward our standard questionnaire and make one for you, if needed.
As of 2010 all existing and new VPA's can be upgraded with the capability to test electronic injectors as well. As of the VPA 1100-5, this functionality can be built-in from the beginning as an option.

PPMI 1000 adaptor - for correct testing of MAN Diesel Slide Valve Fuel Injectors
The PPMI 1000 is an upgrade designed for IOP Marine / Ib Obel Pedersen VPU 1100 test rigs, allowing a traditional analog test rig to test MAN Diesel slide-valve fuel injectors correctly.
The IOP SafeTest Technology (Patent Pending) is the only way to make sure that MAN Diesel slide-valve fuel injectors cannot be damaged during testing and overhaul.
Compatibility
The PPMI 1000 unit can be fitted on traditional air-powered test rigs from IOP Marine - Obel-P-Products, Ib Obel Pedersen, HANMI Hydraulic, Daixin, Woo Am, Nagao, Lushi and other Asian manufacturers supplying traditional test rig solutions. The manual covers basic installation for any kind of air-powered fuel injector test rig.
PPMI 1000 - retrofit for exisng installations
The PPMI 1000 is the only solution available for the testing of slide fuel valves with a traditional Obel-P or 3rd party test rig, while it features an automatic Slide Valve Fuel Injector protection system (Patent Pending). The unit has numerous features:
- Atomisation test cannot be executed by mistake.
- Opening pressure test performed correctly.
- Precise digital read-out (± 1 bar).
- Separate display for data collection (opening/venting pressure).
- Can be mounted on all test rigs.
The PPMI 1000 is supplied with a detailed installation guide and all parts needed for installation. Installation takes less than 20 minutes and can be done by the onboard crew.
Test Rig Air Purification - Oil mist separator (for use with VPU / VPUD test rig)
An aerosol of oil mist is produced when injectors are tested. And no matter the test medium, such aerosols are not desirable in the air that you breathe and work in.
The oil mist separator completely replaces the need for traditional air suction systems and can be installed onboard newbuildings as well as retrofitted for existing IOP installations. The Oil Mist Separator is attached directly to the IOP fuel injector valve holder and is powered by the same air that powers your test rig, making installation a very simple task.
The air extracted from the test chamber on a VPU unit is condensed in the filter, making it possible to re-use the condensed oil mist for future testing. The purified air is clean enought to fulfill the strict requirements set forth by the Danish Maritime Authority (DMA) among others, and can be ejected to the surrounding air without further cleaning. It is also possible to attach a pipe and lead the purified air outside, if desired. Oil mist separator solutions are available for both ships and workshops, and compared to traditional ventilation systems, the IOP Oil Mist Separator is both inexpensive and small, and it does not require any special skills to install.
The solution has been tested and approved by the Danish Maritime Authority (DMA), and is installed onboard more than 150 vessels under danish flag.
