Non-Nitrogen HALT System
Accelerated Testing withMechanical RefrigerationThis new HALT system with ESPEC cascade refrigeration eliminates theneed for liquid nitrogen, making basic HALT testing possible for customers and locations where traditional HALT systems just aren't feasible.EQZ42EQGNZ27
Platinous FeaturesFeaturesHALT testing without using Liquid NitrogenThese HALT systems eliminate the need for liquid nitrogen, making basic HALT testing possible for customersand locations where traditional HALT systems just are notfeasible. Whether liquid nitrogen is too difficult or costlyto attain and maintain, or just not possible, this is youranswer. (This system has an option for liquid nitrogenboost, by just using it during rapid thermal ramps, but canlet the refrigeration take over for soak steps.)The repetitive-shock table creates a combined environment needed for full HALT testing. This all-in-one systembrings together the proven, quality technologies fromESPEC and Qualmark product lines.Standard features All stainless steel constructionP-300 touch-screen controllerProduct temperature controlCascade refrigeration with scroll compressors andelectronic expansion valve controlDry-air purge for dryness and positive pressure duringcycling (nitrogen purge may be substituted)Vibration table with six-degree-of-freedom, repetitiveshock. OmniAxial broadband distribution and improved the Power Spectral Density (PSD) stability.Emergency stop buttonLeft-hinged door with window and LED lightingEQZ4 interior with 18" x 18" repetitive shock tableAir-cooled models availableHigh performance test chambers usually mean watercooling utilities are required. The 3 or 6 hp chambers areavailable with integrated air-cooling. Chambers with higherpower refrigeration are available with a remote air-cooledcondenser instead of water-cooling.EQGNZ27 interior with 30" x 30" repetitive shock tableThe repetitive shock actuator is a pneumatic hammer thatrepeatedly impacts the table to create random vibration stressto your test sample.3
PerformanceP-300 ControllerTemperature cycling up to 15 degrees perminuteTemperature cooling is via cascade refrigerationwith high reliability Scroll compressors. Two models have built-in air cooling, others require coolingwater. These expand the options for implementingHALT testing where liquid nitrogen isn't available.Repetitive shock performanceOur accelerated stress test systems have sixdegree-of-freedom (6DoF) repetitive-shockvibration tables. The table delivers low frequencyenergy for penetrating complex products, whilemaintaining high frequency energy that effectivelyexposes weak solder joints and surface mountproblems.The complex engineered system that generateshigh and low frequency excitation also simultaneously generates rotational stress. This results intrue 6DoF stresses (roll, pitch and yaw aroundthree axes, plus X, Y and Z vibration) for effectiveHALT testing.Get a performance evaluation to helpselect your modelFor better assurance of performance for the temperature cycling part of your application, ESPECcan provide a guaranteed performance calculation based on your submitted requirements.Please use these questions (at right) as a guideto define your test plan. You can then give thisinformation to your local sales representative,or submit at www.espec.com, for review by anESPEC engineer. A recommended model withappropriate refrigeration size will be returned.Air Temperature, CTemperature cycling rates of up to 15 C/min. arepossible without liquid nitrogen.180150Cooling RateEQGNZ27-6NAL2.55 C/mEQGNZ27-12NWL2.5 10 C/mEQGNZ27-15NWL2.5 15 C/m100500Heating Rate8 C/mEQGNZ27-6NAL2.5EQGNZ27-12NWL2.5 12 C/mEQGNZ27-15NWL2.5 15 C/m-50-70306090 120 150Time, minutesQuestions for performance evaluation request:1.

Advanced ControlEnhanced performance and USB accesswith P-300 touch-screen controllerThe exclusive ESPEC P-300 programmer/controllerbrings energy savings, user-friendly operation, andexpanded data access to the ESPEC chambers.Tabs on the updated user interface allow fasteraccess to any screen. Standard USB and optionalEthernet interfaces make programming and dataacquisition much simpler. In addition, improvedalgorithms make operation more energy efficient,and temperature ramping faster, smoother and morerepeatable. Store up to forty programs, as well as threeconstant-mode configurations. Multilingual display in English, Japanese, Chinese, or Korean. Alarm history and diagnostics, plus a ‘back trace’feature for troubleshooting.Standard USB port for upload/download of programs and test data. Test programs can be editedand stored on a PC using included software, thenuploaded via USB. Operation data can be downloaded for review, graphing, or exporting to Excel.The console includes the P-300 programmer, USB port, product temperature protector, and chamber light.Included: The Web Controller add-on allowsremote operation, programming, and data-loggingvia a web browser or API.Part Temperature, CIncluded: product temperature control80No Boost20 C Boost6040200Time Saved: 34 minutes-20-40-60010203040Time, minutes50 Controls product temperature Enables faster product change rates Shortens testing timeDuring normal cycling tests, product temperaturecan lag behind air temperatures up to 20 degrees.The product temperature control is a valuable feature for high performance testing This feature drivesfaster change rates by directly monitoring producttemperature and automatically boosting air-temperature setpoints until the sample approaches thedesired temperature.60Product temperature control generates faster ramp-rates for test samples, aswell as significant time savings for soak periods.5
