Products & Services
Deckmaster Central & Remote
The DeckMaster Deck Unit is a liquid level display and alarm status unit intended for installation on the deck of a barge or tanker. Combined, several Deck Units and the DeckMaster Central Conditioning Unit meet the cargo gauging and alarm requirements of the USCG’s vapor emission regulations (46CFR39). The user may scan the level and alarm status of any tank in the system from any Deck Unit.
JOWA 3SEP OWS
The JOWA 3SEP OWS is a dual stage oily bilge water separation system utilizing differential specific gravity, coalescence plates and filtration to separate and remove free and emulsified oil. The system is designed as a skid assembly with all connection points collected for easy installation. To eliminate corrosion problems the tanks are made of stainless steel, AISI 316L. Spare parts are easily available from one of our offices or representatives worldwide.
Sterilizing drinking water with silver is a very old method and is even mentioned in ancient Egyptian writings. Disinfection of water by dosing silver ions into water is completely harmless to humans and animals. It does not change the water’s physical or chemical properties nor the taste, smell or color. The silver ions do kill bacteria, germs, and algae that are present. Since its introduction in 1970 thousands of ships have installed it and due to its simple design and high quality many of these first units are still in use today.
JOWA Emulsion Breaking Unit (EBU)
JOWA Emulsion Breaking Unit is designed to break apart water in oily water emulsions. The unit separates up to 80% of the water in the emulsion. The treated water is then fed to an IMO MEPC 107(49) approved filter type/bilge water separator such as the JOWA 3SEP. Use of the JOWA EBU combined with the JOWA 3SEP can reduce oil discharge levels to 2PPM or less.
The JOWA ODME 2005 Oil Discharge Monitor is approved as a “third generation” monitor, based on IMO resolution MEPC 108(49) and MEPC 240(5) for Biofuel blends. It is easy to operate and has a menu that is self-explanatory. The equipment is robust and easy to install and maintain. Its unique self-cleaning feature makes manual cleaning virtually unnecessary. The high quality JOWA ODME is designed to last many years, even in rough environments.
Metritape Level Sensors
With its innovative resistance-tape technology, JOWA USA provides reliable level gauging solutions for a diverse and demanding mix of applications. Commonly known as Metritape, this nonmechanical, continuous level sensor offers clear advantages over other level technologies, especially in thick, sticky liquids that cause mechanical level gauges to seize. With over 25,000 units installed throughout the world, the Metritape resistance-tape level sensor is a proven success with high user acceptance and customer loyalty. Applications include cargo, service, fuel, ballast and draft. Combined systems can monitor inert gas pressure to meet IMO regulations.
JOWA iPack Oil Maintenance Unit
Highly automated filtration system for maintenance of hydraulic and gear oils. Extends life-cycle of oils and equipment through removal of particle and water contaminants. The system is compact and easy to use with both “Fixed” and “Mobile” versions available.
JOWA Water in Fuel Emulsions (WFE)
The system will produce a stable emulsion of water in fuel oils. The emulsion is based on a variable percentage of water to the fuel oil flow rate. Results in: Reduction of NOx emissions Reduction of fuel oil sludge Improved combustion quality and reduced PM emissions Reduced wear on engine components and reduced operational costs
