3 COMPANY BACKGROUND From a bold idea to a fully developed piece of engineering Grünewald GmbH is renowned for is standard of high quality and continuous development in the field of control and measuring engineering. Our foundation is based upon skilled and trained staff, the most state of the art production procedures, internal process optimisation, high quality raw materials as well as certified quality control. Due to the high adherence to customer demand, we distribute our, in Germany manufactured products worldwide. Our long term experience is our greatest strength. Constant public relations, and the resulting feed back, feeds out innovations, flexibility and our requirement orientated development. Finest measuring engineering with long lasting durability under very difficult conditions, even in explosion endangered areas are our strength. We specialise in building measuring instruments for the coal mining industry. Experience creates confidence Our company was found in 1976 in Remscheid, Germany. Even back then, it was important to our company to produce a durable, high quality product using innovative procedures. In 2001 Mr. Lothar Schnickmann and Mr. Michael Wolf took over management of the company. The company then expanded, and under the conditions of excellent traffic connections, resettled to Hamm in Westphalia. Due to the new location, it is now possible to react much faster to customer demand, to optimise manufacturing possibilities, and be in the basic area of our customers. Experienced, innovative, flexible and young, this is how we present ourselves today to our customers throughout the world. We engineer measuring and control equipment, such as Volume flow, Temperature, Pressure and Level measuring devices as well as Control units and temperature switches for the use in explosion prevention areas. Our expertise lies in the field of measuring equipment and monitoring units for industrial coal mining. 3

4 INTRINSICALLY SAFE MEASURING SYSTEM TYPE UNi The intrinsically safe measuring unit type UNI are constructed for the use in Volume / Pressure / Temperature and/or Level measuring, of liquid or gaseous media in closed and filled systems. Universal measuring instrument for Volume m³ / h NEW! with external Display Pressure up to 600 bar max. Temperatures -20 ºC to + 60 ºC Level Combinations of the above mentioned of liquid or gaseous media s NEW! with internal temperature-measurement The intrinsically safe measuring units are supplied with a 12 V DC power supply unit from a different mining industry supplier. The electronics are situated in a robust, shockproof casing made of red brass. When a LC-Display is required, the casing cover is made of Plexiglas. Depending upon the configuration required, a threaded fitting (M20x1,5) with the length of cable requested, a four pin jack socket from the company PROMOS, or a cable box which is fitted to the electronics casing can be ordered. The analogous transfer signal range is from 5 Hz to 15 Hz. For the inspection and for the balancing of the transmission route, a switchable spot frequency from 5 Hz to 15 Hz is available. Two infinitely adjustable boundary values with a floating transistor exit (NPN) are situated in the electronics. User defined mounting position.

5 VOLUME FLOW MEASURING The medium that is being measured flows through a hole inside of the housing and starts to turn the turbine wheel. The turbine wheel is fitted with five enclosed magnets. The magnetic field is registered and evaluated by the electronics and according to the set parameters for the nominal width, the flow volume is showed using the display. All necessary parameters and adjustments for the nominal widths of the UNI devices are set by the manufacturer and do not need to be changed. Devices with thread fittings and a nominal width between DN 15 and DN 50 are built out of brass (MS58). Devices with flanges and a nominal width between DN 50 and DN 300 are built out of steel (ST37) and have an internal brass (RG7) bush fitted. The Volume flow can be transmitted as an analogous measured value Signal range 5-15 Hz and / or 0/4-20mA transmitted as a digital boundary value 0-50% and % infinitely adjustable Both signals can be carried out separately or combined.

23 INTRINSICALLY SAFE FLOW VOLUME CONTROL UNIT TYPE RV The flow volume control unit is constructed for use as a regulating valve for liquid and gaseous mediums in a filled and closed system. The installation size starts with DN 50 and is able to go up to DN 300. The cylinder barrel is located inside of the valve housing, and driven by an eccentric tappet. This can be stopped in any position and restarted again in the same direction or in reverse. The run time is approximately 90 seconds. The valve housing is made of steel (St 52.3) and the cylinder sleeve as well as the cylinder barrel are made of red brass (RG 7). If the unit is to be used with aggressive fluids or gasses, both cylinder sleeve and cylinder barrel are available in stainless steel (1.4571). The power supply for the electrical drive and electronics of the control valve, are supplied by the intrinsically safe power supply unit. The valve positioning signal is transmitted through a 0/4 to 20 ma signal or a current signal * to ** V. Additionally, a digital signal with a band width of 5 Hz to Both end position of the control unit OPEN and CLOSE, are provided as a potential free relay output inside the terminal box. For the drive and fault clearance purposes, the potential free contact at the potential free optocoupler must be used. 23

24 The regulating valve has an automatic repeating circuit wiring. If the cylinder barrel is blocked, an inversion of the direction will occur. After a preset time ha elapsed, the inversion activity will stop and the drive will commence in the foreseen direction. If the blockage is still not cleared, the regulating valve will then go into a Fault sequence, and is switched off electrically and locked. A signal at the fault clearance inlet will cancel the electrical locking. If power failure occurs, the control valve can be opened or closed using the handwheel provided. To avoid damage during transportation the handwheel is provided separately.

27 HEAT EXCHANGER MONITORING UNIT TYPE WMT The intrinsically safe heat exchanger monitoring unit type WMT *** - * is for the use in monitoring cooling equipment and their heat exchangers. The WMT monitors the flow volume as well as the temperature of the flow and return cooling mediums, using an UNI measuring instrument. All measuring values are transmitted using a linear signal 5 Hz to 15 Hz, whereas the flow volume is shown locally using a separate digital LC-Display. The signal connection and transmission take place using the much approved PROMOS coupling system. Using the PROMOS coupling system, it is possible to trigger the internal integrated cleaning jet valve. It is also possible to directly trigger the cooling ventilators via the integrated hand switch which is located inside of the unit. The electrical and mechanical connection of the WMT unit occur using plug-in connectors. Because of the compact construction and the plug-in connectors, a very quick and assembly friendly installation is given, and a very good cost/performance ratio as well as a minimised down time of affiliated machinery is guaranteed.
