8 Description and Principle of Operation PPLITION In order to accurately analyze combustion gases, moisture must be removed from the sample without removing gas components of interest. The Universal nalyzers Thermoelectric Gas ooler provides an ideal repeatable, and stable way to decrease the dew point of combustion gasses. This prevents water condensation in sample prefilters, sample pumps, and gas analyzers. Where water vapor is an interferrent, a stable and repeatable dew point becomes a part of the gas analyzer s performance specification. The 500 Series ooler provides this constant, resulting in an accurate analysis of the gas components of interest. The gas sample is first pulled through a sample probe, which usually contains a heated filter, and then through a heated sample line, which keeps the sample above its dew point. The 500 Series ooler then condenses water out of the sample, which lowers the dew point to 5 (41 F). The 500 Series Thermoelectric Gas oolers are for general purpose, light duty applications. Several models are available to meet various application conditions. Use the cooler selection chart below to best fit a model to the expected flow rates, water vapor concentrations, and ambient temperature conditions. If none of the models listed meet the needs of the application, contact your Universal nalyzers local sales representative for more options.

9 Description and Principle of Operation DESRIPTION The Universal nalyzers 500 Series Thermoelectric Gas oolers condition gas sample streams to remove water vapor. The gas sample is cooled thermoelectrically to a controlled temperature, and water vapor is condensed and removed. The key to success is being able to condense the water from a wet gas sample with a minimal loss of the water soluble gas fraction. The separation occurs in a classical impinger, which has a highly polished cylindrical surface, cooled to the desired dew point temperature. The gas sample is brought to the bottom of the cylinder through an insulated tube and allowed to rise through a narrow annular area at a relatively high Reynolds number to insure the entire sample is influenced by the cold surface. The condensate falls down the cold, polished surface in the form of a sheet (as opposed to droplets or the bubbling of the gas sample through the condensate) which minimizes the surface area in contact with the gas sample. The temperature of the cylindrical, condensation surface of the heat exchangers is maintained through intimate contact with aluminum heat transfer blocks. The blocks are cooled with thermoelectric elements, controlled to a temperature of 5. The temperature sensor is a type K thermocouple. The temperature controller is proportional with a band of 1. The fan cooled heat sink is constructed from anodized, pure aluminum fins which transfer heat to the surrounding air. The pure aluminum material is a far better conductor of heat than the aluminum alloys which are normally used for extruded heat sinks. The result is an assembly with superior heat exhausting capabilities under high ambient temperature conditions. The 500 Series oolers have a digital display for front panel indication of the operating temperature of each of the heat transfer blocks (switch selectable) in degrees entigrade. Two internal jumpers at the top of the control circuit board within the enclosure can be moved to change the indicated temperature to read out in degrees Fahrenheit. Three LED lamps to indicate the status of the cooler. The OOL lamp is a green LED which indicates when the operating temperature has fallen below the factory set temperature of 10. n Over-temperature relay is energized and closed to the cool position when the OOL lamp is on. The relay board within the enclosure has dual terminal strip relay contacts for alarm/shutdown purposes. The external gas sample pump may be interlocked with this relay to power off when temperatures become too high (fail safe). The DRY lamp is a green LED which indicates when there is no water in contact with the water carry-over sensor (provided separately or as a system option). If no moisture sensor is used, the lamp may be turned off by installing a jumper on the moisture sensor input terminals on the relay board. Without a moisture sensor installed, the DRY lamp is always lit and doe not indicate a condition. The moisture sensor relay, which is energized in the DRY condition, provides contacts to an annunciator panel and/or to turn off the sample pump in the wet condition. The T lamp is a red LED which indicates when there is a problem (open connection) in the temperature control thermocouple. The Over-temperature relay will also transfer to the high temperature condition if the red T lamp comes on. Universal nalyzers Sample hillers are designed to interface with a condensate carry over sensor. The standard sensor is provided with a filter (which is referred to as a SF ) or it can be ordered without a filter ( S ). This sensor is put in place as an early warning device to ensure that a clean, dry sample is presented to the analyzer(s), thereby minimizing future maintenance and/or costly repairs. ondensate sensor (S/SF) sold separately for 500/1000 series coolers. The sensor is designed to operate with any current model Universal nalyzers sample chiller. If the sensor needs to be used as a standalone device then a 100 Moisture Detection Module must be used in conjunction with the moisture sensor. The technology behind the SF is a capacitive proximity sensor this is advantageous because the condensate does not need to be conductive to trigger an alarm. The sensor has an M12 connector on the bottom and uses the same 1 meter cable (Universal nalyzers Part No ) to interface between the S/SF and all chillers and the 100 Moisture Detection Module. In addition, there is an LED indicator on the sensor itself that illuminates upon detection of condensation or particulate. Page 9 of 43

If the pump is placed ahead of the sample cooler, it should be provided with a heated head to avoid the condensation of water vapor. If the sample pump is placed after the sample cooler, drawing the sample through the cooler, the sample has been dried, and a standard, non-heated pump may be used. means to control the flow of the sample through the system should be available and visible to the operator. This may be accomplished through the use of pressure regulators with gauges, flowmeters, and/or flow control needle valves. ondensate removal from the heat exchanger(s) within the Sample ooler can be accomplished through one of the following methods: 1. continuously running peristaltic tubing pump. 2. Installing the heat exchanger as a bypass condenser, pulling excess sample through with an eductor. 3. Using float drain traps similar to a steam trap. This requires the sample within the cooler to be at a positive pressure. 4. Use of drain pots on level control with a removal pump. Page 10 of 43

11 Installation The 500 Series Thermoelectric Gas oolers are best suited for air conditioned environments. Each unit dissipates heat, and the surrounding area must be well ventilated to provide adequate cooling. The cooler should be located away from other heat sources. If located inside an enclosure, outside air should be ducted directly onto the heat sink, and thermostatically controlled fans and vents should be utilized. The interior of the enclosure should be insulated, and never mount the unit in direct sunlight to avoid solar heat loading. Route all sample gas lines directly to the 3/8 inlet tubing fittings located on the top of the cooler heat exchangers. When two gas streams are being cooled, the left side of the unit is considered to be channel 1, and the right side of the unit is channel 2. Sample outlet tubing fittings are reduced to 1/4. t the bottom of each heat exchanger, a 3/8 tubing fitting is provided for the condensate drain. The condensate fitting may be removed to expose a female 3/8 NPT connection. Equipment must be installed to remove the condensate such as a peristaltic pump, liquid drainer, or aspirated drainer. single head peristaltic pump is recommended. If an aspirator drain is utilized, the outlet tubing should have a small bore and be no longer than two feet to minimize back pressure. The drain must be run to an appropriate condensate disposal location. sample pump is normally required to pull the gas sample through the cooler. Water arry-over Filter (WOF) sensor is recommended for each sample path. The pump should be located between the cooler and the filter. clear glass bowl should be installed around the filter to allow checking of the condition of the filter while online. Each cooler consumes about 2 amps (at 115V) per every active heat exchanger. Use minimum wire size of 18 WG, stranded, tinned copper with a minimum rating of 300 Volts. Dual relays are provided for both the WET/ DRY and HOT/ OLD conditions. One set of relays are MOV protected and designed to interrupt power to the sample pump upon alarm. The temperature of the heat exchangers may be viewed on the display on the front of the unit. If a multiple channel unit has been provided, a selector switch on the right side of the display lets the user toggle the display from one block to the other. For these same cooler models, a second toggle switch on the left side of the display allows the user to view the settings for the relay and cooler temperatures. Jumpers inside the unit on the control panel allow setting the display for degrees elsius or degrees Fahrenheit. Sample pumps, SF sensors, drains, flow meters, regulators, and other optional equipment are available from Universal nalyzers. These may be purchased separately or installed on a complete 500 Series Sample onditioning System. ll installations shall be in accord with the manufacturer s instructions and the National Electric ode (NSI/NFP 70).

18 Start-Up pply power to the Universal nalyzers 500 Series Thermoelectric Gas ooler. The indicated temperature will start to drop immediately. It should be below the over-temperature set point in approximately four minutes and the OOL green LED lamp should light. When the temperature reaches the control point (set at 5 ), the rate at which the temperature drops will be reduced. It will stabilize between 4 and 5. Start the sample gas flow. Water should be observed to be removed from the bottom of the heat exchanger when steady state conditions are established. If condensate sensors are installed, the (DRY) light should remain on as dry gas is transported to the analyzer(s). Turn on the analyzer(s) and calibrate as required. Shutdown Stop sample gas flow to the Universal nalyzers 500 Series Thermoelectric Gas ooler by turning off the sample pump. llow the drain pump to run for several minutes to remove any remaining condensate from the heat exchangers. fter all condensate has been drained, turn off power to the cooler. Page 18 of 43

19 Maintenance efore performing any maintenance on the 500 Series Thermoelectric Gas ooler, ensure that all plant safety procedures are followed. The 500 Series ooler is designed for maintenance free operation, but if any is required, ensure power has been removed before maintenance is performed. For the best performance of the cooler, the following maintenance schedule is recommended: Maintenance ctivity Peristaltic pump Diaphragm sample pump lean heat exchanger Inspect heat sink fins Frequency Replace tubing every 3 months Replace diaphragm every 6 months nnually Monthly Page 19 of 43

20 Troubleshooting The following table should give an overview of possible errors and an instruction to check and to repair them (is not valid for the starting-up period of cooler). Error Possible reason heck/repair The presence of water Overloading of the refrigeration capacity of the cooler due to too much water vapor or too great a sample flow rate fault in the condensate removal equipment.
