Water in oil can cause costly breakdowns totaling hundreds of thousands of dollars in lost revenue. It is impossible to escape the problems of water contamination in oil systems. Recently there have been initiatives to determine the feasibility of extending the life of oils or determination of oil change period by analyzing them for water content using an online water-in-oil analyzer. Online measurement of many types of hydraulic oils, lubrication oil and fuel oils . diesel etc by the EESIFLO EASZ-1 water in hydraulic oil analyzer reduces the need for a laboratory to analyze the water content of oil samples. It also acts as an added guarantee because water in oil is continuously being measured online.

In addition, the EESIFLO water-in-oil analyzer can be tested onsite or in a laboratory setting for further accuracy and verification against a Karl Fischer coulometric titrator in determining water content in oil. Many clients and organizations have taken the lead as a part of an ongoing effort to eliminate waste and reduce pollution have been looking for a way of extending the operational life of transmission and hydraulic oils, determining fuel quality for engines and reducing the risk of breakdown from water contamination in lubrication systems.

Implementation of an effective oil extension and monitoring program needs some thought. In some cases for e.g with high speed purifying systems, the ability to perform accurate water content analysis in a factory or a fleet would allow purified oil to be returned to service more quickly. The EESIFLO EASZ-1 is a unique and affordable accurate online water in oil detector. It can measure as low as ppm and percentages of water including free water .Some application require more thought and logic. This is because of problems encountered with high water content at start up of the purifier system. This high water content needs to be monitored without total destruction to the moisture sensor. Unfortunately, most moisture sensors cannot be used once they have been contaminated with free water , they simply stop functioning. The EASZ-1 will measure very low ppm levels of moisture contamination (dissolved water in oil) and extremely high water content with no damage possible to its water sensing element.

It is important to address the problems encountered onboard a vessel that has decided to install the EASZ-1 water in oil sensor for e,.g onto a Diesel Generator Lube Oil Purifier Outlet. A robust and reliable Water Content Alarm System for a typical Engine Lubrication System application requires some logic. This logic can be engineered either by ship system integrators or provided as a total water in oil monitoring package supplied by EESIFLO. A typical example would be the a total solution system to solve the problems encountered onboard a vessel after installing the first EASZ-1 onto the Diesel Generator Lube Oil Purifier Outlet. Typically a problem encountered (alarm triggering during startup sequence and purifier desludge cycle) can be resolved confidently using the EASZ-R3, a display and logic device capable of taking on up to 4 EASZ-1 Water-In-Oil Monitors with required functionality. Instead of only one EASZ-1 standard water in oil monitor display for each point monitored ,the more advanced EASZ-R3 can take on both monitoring points in question (Diesel Generator and Main Engine, hydraulics, other lubrication systems and fuel, so only one unit is needed.

Here is an example of a complete system monitoring 2 Purifiers.

More about EESIFLO…….

EESIFLO International is an ISO 9001:2000 manufacturer of flow sensors and water in oil monitors. Our clients span the globe and we have supplied solutions to almost every major industry including oil and gas, petrochemical, chemical, pharmaceutical, aerospace, shipping, water and waste water, paper mills , food production and academic institutes

Moisture in oil-

Continuous and accurate monitoring of water contamination in any oil including Lubrication Oils, Heavy Fuel Oils and Hydraulic Oils, Diesel and any oil based chemical. The EASZ-1 is a unique system which provides Operators of all types of Engines, Turbines, Thrusters, Azipods, Gears, Separators, filtration systems and Stabilizers with a means of continuous monitoring of the oil systems for possible water contamination

The EASZ-1 temperature compensated microprocessor based loop powered water in oil sensor enablesfast and reliable drift free online detection and monitoring of moisturepercentage or ppm in oil. The EASZ-1 can be used in on-line moisture monitoring and as a control instrument allowing se parators and oil purifiers to be started only when needed or as a diagnostic or preventative device protecting critical systems from premature failure. Most important of all is the response time which is seconds. The unit responds very quickly to a change in the capacitance of the oil being monitored and is not affected or knocked out of service by saturation and will continue to work in both high and low measurement ranges. Water in oil can cause quick and costly breakdowns. They can happen so fast that in many cases, water in oil can be treated as a more serious contamination problem than metal particle contamination! Water contamination can occur at any time. It is possible that serious damage can be caused on bearings a nd other lubricated components without the user knowing it is happening. The EASZ-1 water in oil analyzer can give early warning of a problem so that corrective action can be taken

Water contamination drastically reduces the performance of mechanical equipment. Excess moisture or water content can increase the risk of corrosion, overheating, machine malfunction and catastrophic failures causing system shutdowns. Accurate measurement and control of moisture in large lubrication systems is essential for planning, servicing , preventing unscheduled downtime and reduction of overall production costs. The EASZ-1 not only gives you continuous direct readings of oil/water mixtures but also directly measures the amount of free water contamination instantaneously . The EASZ-1 was designed to be an affordable device replacing unreliable spot sampling methods and slow response water activity transmitters which only alert the user if there is a risk of free water contamination and nothing else. The EASZ-1 is an easy to use loop powered transmitter unit using a finely engineered stainless steel capacitance cell and high speed encapsulated microprocessor based electronics resistant to humidity and rugged industrial environments. Most of all, the unit weighs approximately 3 lbs (less than 1 kg) and can be set up and running in minutes. The EASZ-1 can handle oils with different densities and onsite zero calibration (if necessary) can be done simply through the press of a button.
