www.daikinreefer.comThe most important part of any refrigeration machine is the compressor and thescroll compressor is the right choice for today’s demanding performance andreliability requirements.Scroll compressor:Scroll compressors have already been adopted in the majority of air conditioningand refrigeration applications due to their superior performance compared withalternative technologies. Key benefits include: Fewer partsEasier to manufactureHigher reliabilityHigher co-efficient of performanceLower weightGreater cooling capacityLower power consumptionLower noise levelsReduced vibrationThe scroll compressor used in the LXE10E machine wasdeveloped specifically for container applications, drawing on allof Daikin’s technological expertise. Daikin has been designingand manufacturing scroll compressors for over 20 years. The company is one of thelargest producers of scroll compressor in the world today, manufacturing over 1.2 millioncompressors every year for a wide variety of refrigeration and air conditioning products.Daikin is the only manufacturer of container refrigeration machinery that can offer thislevel of experience and expertise in scroll compressor technology. Advanced designfeatures that ensure the best performance from the LXE10E scroll compressor include:High efficiency asymmetric scrollThe scroll design in the LXE10E features dual suction gas entry technology, withstaggered gas discharge from the two entry compression chambers. This reduces overcompression loss in comparison with a normal scroll compressor, guaranteeing optimalefficiency.The compression process from the suction to the discharge port is also shorter thannormal, thereby reducing heat influence from other areas and improving energy efficiencyHigh reliability bearingsThe compressor uses a rolling bearing for the upper main bearing and a sliding bearingfor the orbiting scroll drive. This combination ensures an ideal oil supply, regardless of thecondition of the suction gas.Page 2 of 923/11/2006

www.daikinreefer.comProper distribution of suction gasThe scroll compressor has a motor housing that can distribute the suction gas to themotor for cooling and to the compression. By providing proper distribution of the suctiongas, pressure loss is reduced while the motor is cooled down sufficiently. This designfeature has improved the volumetric efficiency of the LXE10E scroll compressor byapproximately 3.5%.Highly efficient Trochoidal pumpA stable oil supply for the scroll is guaranteed by the use of a highly efficient Trochoidpump.Anti-corrosive paintReefer boxes and machines are subjected to severe environmental conditions and it iscrucial that the paint on the compressor body is of extreme durability. To ensuremaximum protection against corrosion and the effects of UV light, the LXE10E scrollcompressor is treated with a two-coat paint system: Undercoat: epoxy zincTopcoat: Micaceous iron oxide (MIO)Wide operation range Extended scroll wrap and adoption of gas injection systemHigh durability against shock and vibrationPowerful cooling capacityFor non pre-cooled cargo: The LXE10E has excellent cooling capacity to provide a fasttemperature pull-down, which can prevent chilled cargo from ripening.For deep-frozen cargoes: The LXE10E provides sufficient cooling capacity to ensurereliable transportation with end-user satisfaction. It also extends the reefer box’s lifeexpectancy.The DAIKIN LXE10E machine also meets all the new proposed ISO requirements,currently being discussed.Net Cooling CapacityTemperature (Ti/Ta)Cooling Capacity (watts) 2/ 3810,600-18/ 386,400-29/ 384,000Sensitive temperature controlTo protect fresh products from freeze damage, the LXE10E provides uniform supply airtemperature with its precise refrigerant control system.

Daikin’s hot gassystem provides faster defrosting and with less heat escaping into the cargo area,improved conditions for the cargo.For dehumidification the DAIKIN LXE10E hot gas system provides a fully controllable andpowerful product ensuring your cargo receives the best treatment.Superior reliabilityBy using the best materials and knowledge the LXE10E machine continues to provide thehighest reliability, setting new standards for the container industry.User friendly:The DECOS IIId controller fitted to the LXE10E has been designed for ease andsimplicity of use. It is the only controller in the refrigerated unit market thatprovides a graphical display, eliminating the need to fit and maintain a separatetemperature chart plotterTwin Display monitorA combination of LED and LCD displays means that various modes can be operated andmonitored easily by the user: Continuous monitoring of temperature, alarm etc atship’s deckMonitoring for maintenance work at terminalsAll sensor data can be checked (HP/LPpressure/current/voltage etc)Click touch keyboardThis concentrated control switch supplies thecommunication between the human operative and theLXE10E: Selection of each mode (setting temperature/defrostinterval etc)Altering initial settings (calendar, internal time etc)Automatic PTI function (short PTI/ full PTI/ manual check)Energy saving operation/automatic pump downManual defrostSensor data displayPage 4 of 923/11/2006

www.daikinreefer.comClear and easy to use softwareThe LED/LCD displays, provide access to all sensor data and a graphical display of therecorded temperature. This function enables the unit to beoperated without a separate temperature chart recorder, whilstthe full trip data will also be stored in the controller memory fortwo years.Daikin’s DCCS software has many advantages, providingoperational data control, the generation of reports and analysingthe machine operation: Fast controller data downloads to personal computer.Easy analysis of live operational conditions withsimplified piping diagram and actual sensor data.Easy preparation of Trip/USDA/PTI reports etc.Quick and easy data uploads from your laptop.Daikin Temperature Management System (DTMS)Developed for use with the LXE10E, DTMS is Daikin’s newly developed controllogic that significantly reduces power consumption and provides the optimumtemperature environment and airflow for chilled cargo.DTMS significantly improves refrigeration performance by continually monitoring bothsupply-air and return-air temperatures, together with their rate of change. DTMS is theonly product on the market to monitor all three of these parameters.DTMS works by automatically adjusting thecargo environment inside the containerbased on actual ambient conditions andcargo respiration rates. This continual finetuning enables temperature and airflowinside the container to be controlled withmuch greater accuracy, as the systemresponds to real time conditions.The real time monitoring and adjustmentensures that the refrigeration unit operatesat optimum efficiency, using the minimumamount of power. Automatic adjustment of fan speeds also reduces produce dehydration,particularly for chilled cargoes with a higher water concentration.Page 5 of 923/11/2006
