Profile

Arjay Engineering produces ppm oil in water analyzers, monitors and control instruments for both industrial and municipal applications. These include the petrochemical industry for upstream and downstream wastewater and oil/water separator monitoring and control in applications such as: Produced water Storm water Oil water knockout treaters Bilge water Ppm oil in water analyzers, monitors and spill and sheen detectors Arjay Engineering provides ppm oil in water analyzers, oil on water detection and oil/water separator interface and emulsion alarms. For ppm monitoring, UV fluorescence is typically used. The Arjay light scatter approach is perfect for affordable cooling water leak alarms. Interface and oil thickness monitors employ a capacitance technique for reliable low cost monitoring. For produced water monitoring, theHydroSense 2410 is the model of choice. This analyzer uses UV fluorescence to target the aromatics in the water. Through a simple site calibration, the aromatic response is correlated to a total oil reading in ppm. Oil/water separator controls and oil spill alarms The Level-Ease series of capacitance controls are used to monitor and control the oil water interface levels within tanks. The robust probe design does not have optics or moving parts that can foul. High pressure and a wide temperature range make these an ideal choice for monitoring and control of processes, pumps, and valves. The Arjay float sensors continuously monitor for oil separated to the surface of water. Simple on/off alarms and oil thickness monitors are used to alert when the accumulation of surface oil requires attention, or to shut down pumps that may inadvertently pump oil to drain. Level controls The Arjay capacitance level controls have a lengthy and reassuring background of reliability. Arjay Engineering offer basic probe mounted transmitters and on/off switches. The Level-Ease series is available to meet level display requirements, and has a remote control with multiple relay points and proportional outputs. These can be coupled with any Arjay probe for continuous and point level applications of liquids and solids. Bilge and ballast water monitoring Any of the Arjay HydroSense series are suitable for leak alarming. The 2410 is the industrial non-contacting design for untreated or turbid wastewater. The 3410 and 3420 are the more economical choices and can be used for filtered wastewater or water that is free of suspended solids and turbidity. For bilge and ballast oil content separator applications the 2410 and 3410 carry IMO approval for MEPC.107(49) Heat transfer systems can contaminate the water with oil through pinhole leaks. The Arjay controls will monitor for these leaks. The HydroSense 2410 and 3410 specifically target petroleum oils where animal or vegetable oils do not want to be alarmed. The HydroSense 3420 will respond to any free oil type. Approvals There are many approvals and certifications carried by Arjay products. They vary by product but include: ISO 9001:2000, ABS (American Bureau of Shipping), IMO (International Maritime Organization), CSA, UL, CE, CRN, and ABSA. Certain products can be used in zone 1 and 2, division 1 and 2 hazardous locations through their third party approved explosion proof packaging (Ex d), non-incendive design (Ex n), intrinsic safety barriers (Ex i) or by a purging pressurization option (Ex p and EEx p). Specialty systems Arjay can provide custom panels and systems to suit your needs. Specialty racks can be designed to accommodate accessories and support instrumentation for your application.
