DRAINGUARD®-Sump
Application
The DRAINGUAD®- Sump is a fully automated drainage system for water sumps of filter water separators. It is the preferred state of the art retrofit kit including about everything needed to generate a failsafe drainage system including the water defense functionality to shut down the flow In case of excessive water. The heart of the DRAINGUAD®- Sump is the SLUGGUARD® sensor to detect and differentiate between water and fuel. In case of water the SLUGGUARD® sensor activates the enclosed electrical drain valve. The DRAINGUAD®- Sump is including a service valve to externally check the SLUGGUARD® sensor when required (even during operation).
Automatic Air Eliminator
Pressure Relief Valve:
The pressure relief valve is necessary to ensure that the design working pressure of the vessel is not exceeded in cases of thermal expansion. Connections: Inlet/Outlet G 1/2” female. •
Mandatory accessory according to specification EI 1596 3rd edition Automatic Air Eliminator:
Permits the evacuation of air during filling and closes automatically when the vessel is full of fuel. It also allows the automatic elimination of entrained under flow conditions. If associated piping and tank heights could allow the vessel to self-drain by gravity, allowing air to enter via the air eliminator, a soft-seated non-return valve should be installed. Connections: Inlet 3/4” BSPT female, outlet 1/2” BSPT female.
Sensor Technology
DP-Switch
Developed for aviation refuelling applications
The DP-Switch has been designed to automatically stop the refuelling process when the maximum permitted differential pressure for filter elements is reached. DP-Switch is designed for connection to a mechanical differential pressure gauge that measures the pressure difference between the inlet and outlet of a filter vessel in safety-critical applications. The switching pressure is set to 1 bar (15 psi) and designed to stop the refuelling process automatically. It is suitable for competitive exchange and easy to retrofit. The DP-Switch is conform with JIG Bulletins No. 58, 105 & 111.
Electronic Water Sensor / SLUGGUARD®
Electronic Water Sensor / SLUGGUARD® Qualified to specification EI 1592 1st Edition
Electronic sensor to distinguish between aviation fuel and water. The SLUGGUARD® enables continuous detection of water in sumps of filter/water separators or in drain points of filter vessels. The highprecision switch is also suitable for small filter housings (FBO) in the general aviation area. A blue LED light indicates operating or alarm switching states. An alarm condition is being activated in response to a bulk quantity of free water in the line.
Electronic Water Sensor_AFGUARD
Electronic Water Sensor_AFGUARD Electronic Water Sensor_AFGUARD Qualified to specification EI 1598 2nd Edition Electronic sensor for the detection of free water in aviation fuels. The AFGUARD® is recommended for use downstream of all EI-qualified filtration technologies to verify filter performance. It is designed to interface with various Programmable Logic Controllers (PLC).

WTS Water Treatment System
Application
The intended use of the Water Treatment System WTS is the recovery of collected water being contaminated with solid particulates and fuel (oil) that will need to be separated from the water before it can be discharged to surface water drains. The WTS provides the capability to pump the collected water from the contaminated area into a system that separates any oil and solid particulates from the water. WTS is been ATEX approved for operation within a zone 2 hazardous area (minimum requirement) and therefore compliant with the ATEX directive. The WTS has been designed for simple operation and calibration. It incorporates a calibrated oil/alarm/monitor that controls the separation process. This monitors the oil ppm content in the treated water and only permit discharge if the oil ppm content is below the alarm level. If the oil content in the treated water is greater than Alarm level then the discharge will be stopped and the treated water returned to the contaminated area retained for further treatment. The control system provides the user with clear information on the quality of the water being discharged from the system. This information is been displayed in terms of ppm of oil in the water. If the discharged water is introduced into the seas, strict directives require special attention. Depending on area, different oil content limits must be complied with. If PW or bilge water is to be introduced into the seas, the residual oil content must not exceed a concentration of 15 to 40 ppm on average, depending on area. Other inland applications require much harder limits (e.g. 5 ppm).
Logic Controller / Contamination Control System (CCS) gold
Developed for aviation refuelling applications
Fully automatic touchscreen controller for use in combination with an EI 1598 electronic water sensor, e.g. AFGUARD®. The Contamination Control System (CCS) provides an easy to use interface that is constantly processing the actual water content in aviation fuels. The CCS is designed to process a warning/alarm signal if free water reaches a critical level. The logic controller is compliant to JIG Technical Bulletin No. 110 regarding alert, alarm and data storage requirements. There are two versions of the CCS available, entitled gold or silver version depending on the requirement. The CCS gold has a configurable colour touch screen that can display the actual water content. Connected to a flashing lamp it will provide an alert through sensor measurings. The CCS silver version is designed to be integrated into third party PLCs that are AFGUARD®-ready, and fully configurable to customer needs.
Logic Controller / DPGUARD
Developed for aviation refuelling applications
System for automatic calculation of corrected differential pressure measurement in refuelling applications. The DPGUARD® provides an easy to use interface that is constantly monitoring the condition of the filter elements. There are two versions of the DPGUARD® available, entitled gold or silver version depending on the requirement. The DPGUARD® gold has a configurable colour touch screen which can display the flow rate, the actual DP and the corrected DP. The DPGUARD® silver is often preferred in situation where a third-party system will display the information generated by DPGUARD®.
