  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Data Centre CRAC unit efficiency improvements

    One of the main types of project Munters look at is energy efficiency improvements within the thermal management side. One of the easiest changes that can be made is swapping out the old AC powered motors for EC powered impellors. the reductions in energy is considerable, with some older belt drive unit changes measuring a saving of over 60% this is due to the design of the new impellors and the ...

  • Dynamic Air Permeability Testing - An Important New Tool

    ABSTRACT A new method and instrument is discussed for dynamic air permeability testing of airbag fabrics. This new method provides for much more representative test results as the commonly used static, low pressure air permeability test. The use and significance of the dynamic air permeability and air permeability curve exponent are explained for both, the airbag system designer and the airbag ...

  • Importance of Air & Water Testing in Indoor Pools

    Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

  • Ultrasonic Testing For Non Destructive Testing

    Ultrasonic Testing or UT as its known has programs in a wide range of sectors, from aerospace, automobile, to substance, oil, large storage space, and power creation and overseas. UT is aspect of a selection of techniques known as NDT (Non Destructive Testing) methods. Their objective in industry is to allow the examination of parts and equipment ...

  • EPA Regulations Raise the Bar for Industrial Air Quality Testing

    Far-reaching environmental legislation continues to change the way Americans live, work, and run their businesses. For the past ...

  • AIRE-O2® Aerators tests number one in three critical areas

    Problem In 1986, this southern USA fine paper mill developed problems on start-up from a Christmas shut-down, requiring quick action to add efficient aeration to its 38 MGD (143,830 m 3) flow. Poor winter treatment, channeling throught the system, and high solids had also been problems. Since the company was committed to preserving the environment, it searched for the best aerators to meet its ...

  • Equivalence of Air and Water Permeability Tests in Evaluating Engineering Fabrics

    Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability tests are discussed, and results from these tests are correlated to air permeability results for filter fabrics. Several commercially ...

  • Purpose of Air and Surface Mold Sampling or Testing during Assessment

    As part of determining whether an indoor environment is contaminated with excessive amounts of mold and requires remediation, Indoor Environmental Technologies (IET) routinely performs air and surface mold sampling or testing. While there are many types of sampling, IET uses two of them the most: Air sampling using a “spore trap” sampler. Considerable information ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • US EPA airmOzone TESTS

    The US EPA leads Photochemical Assessment Monitoring Stations programs (PAMS) for more than 15 years and many equipments used at PAMS sites are old and need to be replaced. That is why US EPA has conducted a material review of fully automatic GC units able to by analyze the 56 VOC ozone precursors of the PAMS list. They planned to perform an evaluation in two steps : - Laboratory evaluation of ...

  • Vibration testing of fuel probes

    Aerial Refuelling The American Bell-Boeing V-22 Osprey is a multimission, military, tilt rotor aircraft with both a vertical and short takeoff and landing capability. It combines the functionality of a conventional helicopter with the high-speed cruise performance of a long-range turboprop aircraft. But even though it is long-range, some missions require in-flight refuelling. The V-22 Osprey can ...

  • LIMS Essential for H2O Testing
