ALARM, WATER INGRESS

JOWA USA's MetriGuard Water Ingress Alarm System is intended for use on bulk carriers. MetriGuard operates with the unique Metritape sensor that provides reliability and accuracy, even in demanding cargo hold conditions.

Protected from damage in a stillpipe that runs from the weather deck down to the inner bottom of the hold, the Metritape sensor allows two alarm set points to be derived from one sensor. Liquid level indicators can be added to metriGuard, which makes it possible to monitor water levels and allow for additional alarm points.

With approved intrinsic safety barriers, MetriGuard may be operated in hazardous areas.

emulsion breaker unit available as an option, to solve the problems when there is an emulsion of oil and water in the bilge tank.
The 3 step separating system design (3 tanks) has been developed for this purpose. The JOWA 3 SEP OWS combines the advantages of easy instalment, durability and low maintenance demand, which brings down
the costs considerably.
The bilge alarm continuously measures the purified water, which is reduced to less 
than 15 ppm when discharged. 
Jowa 3 SEP OWS is available in 
capacities ranging from 0-10 m3/h.

EMULSIONS BREAKING UNITS

The EBU-8, Jowa Emulsion Breaker Unit is designed to separate water from oil emulsions. The EBU-8 unit removes up to 80% of the water in the emulsion.This water (called treated water) is then fed to the bilge water separator with bilge alarm, for checking that the discharge does not exceed 15 PPM. The residue is pumped to the concentrated sludge tank.

FUEL HOMOGENIZERS

With fuel oil often accounting for more than 40% of vessels operational costs,efficient combustion is of crucial 
importance for ship owners and operators. Furthermore, fuel oil quality can have serious long term implications for engine wear and its associates costs.With this in mind JOWA has drawn on its 
technical expertise and experience in the design of specialist ships equipment to 
develop a fuel homogenizer.
The JOWA HOMOGENIZER has been specifically designed to solve the uniformity problems ship owners an doperators face 
when running on fuel oil. the JOWA HOMOGENIZER incorporates a patented 
seal concept and special hard material combination, suitable for very high pressure and temperature applications. 
The unit is manufactured to the highest standard of quality.
There is no better chemical-free approach today for the treatment of heavy fuel oil and sludge than the JOWA HOMOGENIZER.
