  • Frequency Control Air Compressor Solution (.pdf)
    electricity. All of these request sequential operation of corresponding switches, valves and control transducers. When operating, check air compressor conditions frequently. In case of temperature, pressure or motor rated current exceeding limits, stop running immediately. If pressure is high
  • Monitoring Temperature and Power on Aging 3-Phase Compressor Motors
    CAS DataLoggers recently helped a frozen product manufacturer to monitor temperature and perform power factoring on several large 3-phase compressor motors used for refrigeration. As these compressors aged through valve leakage and piston ring deterioration, the AC temperatures fluctuated which
  • Managing Peak Demand
    may vary. Bringing additional air compressors online can incur peak demand charges by exceeding the allotted consumption or by causing energy consumption spikes as the compressor's motor comes on line. In either case, plant managers agree, "you still need air." The philosophy of one large compressor
  • Improving pneumatics bottom line
    the largest single electrical appliance in a manufacturing plant is often the compressor motor. Here's a look at some commonsense ways to determine the operating costs of typical pneumatic circuits. By knowing the facts, designers can make better decisions that lead to more-efficient systems. Because
  • Higher rotational speeds for micro gas turbines
    High speeds are not only required in applications where a motor is used to drive a compressor, micromachining spindle or a mirror. More and more high-speed generators, with speeds of 300,000 rpm and beyond...
  • Applying Inverters to Centrifugal Compressors in HVAC Chillers (.pdf)
    When applying an inverter to centrifugal compressors on HVAC chillers, there are a number of factors to consider. For some compressors, lubricating oil circulation may be driven by the rotation of the compressor shaft itself, via a gear-driven pump arrangement. If you slow the motor speed
  • Product & Technology Overview of Celeroton
    Speed, torque, power, mass flow, volume flow, pressure ratio or pressure difference - absolute or relative? These are just some basic specifications of an ultra-high-speed motor or turbo compressor. To clearly display our product portfolio and to facilitate the selection, we have developed the two
  • Hydraulic Pumps
    The power source is the key element in a fluid-power system. In a pneumatic system the power source is an air compressor, while in fluid-power systems it is a pump. These normally are driven by an electric motor or internal combustion engine. Various concepts are applied to convert the mechanical
  • Medical Device Link .
    Rated at 15 L/min, a swing-piston compressor is available for use in medical equipment such as nebulizers and suction apparatus, and as a pneumatic air source. The 5-in.-long NPK09 features a brushless dc motor, and generates 100 psi of pressure and vacuum to 27 in.Hg. Suitable for portable
  • IR Thermography Assessment Enhanced Compressed Air System Operations & Indirectly Slashed $26K Utility Bills at New Jersey International and Bulk Mail Center
    to switch-over to our alternate high HP compressor. This alternate 150 HP compressor, located in the penthouse, was serviced frequently in 2002-2003 for a variety of problems. To avoid additional service calls and problems with overall effectiveness of the compressed air system, the servicing contractor set
  • Improving Energy Efficiency in Pharmaceutical Manufacturing Operations
    of the electrical energy used by an industrial air compressor is converted into heat. In many cases, a heat recovery unit can recover 50-90% of the available thermal energy. It has been estimated that approximately 50,000 btu/hour of energy is available for each 100 cfm of compressor capacity [19]. Payback periods
  • Automatic Belt Tensioners Maintain Proper Tension, Improve Efficiency
    and achieve cost savings. On many AC units, the drive system often utilizes the popular V-belt to transmit power from the motor to the fan and/or compressor. Some companies would have you believe that this well-established power transmission system is outdated and inefficient, suggested the path
  • Attachment anxiety
    identification tags on compressor motors. Cyanoacrylates also find use as instant adhesives in glassto-glass bonding of large shelf assemblies inside the refrigerator. Advances in appliance technology are bringing new roles for adhesives. Traditional uses still abound. For example, adhesives find
  • Cool Electronics Hot A/C
    innovations in motor design and control technology. Specifically, they have employed variable-speed compressors to good effect in HVAC. It is helpful in this discussion to review the ways in which an air conditioner dissipates energy. Air conditioners transfer heat by circulating a refrigerant
