Schaffner EMC has introduced its ECOSine® 60 Hz Passive Harmonic Filters. The company says the filters remove harmful harmonics of a pre-determined order to increase the reliability of supplied power, and thus extending the service life of downstream components. With plug-and-play convenience and compact dimensions, the product can be more easily installed and commissioned.
The Drives & Motion Division of Yaskawa America has introduced the Z1000U HVAC Matrix Drive. The company says the drive provides extremely low harmonic distortion in a space-saving design, along with the same HVAC-specific features as the standard Z1000.
Air Solution Co. has introduced a Cottonwood Filter Screen and Hail Guard System. The system can stop hail and debris from causing problems in an HVAC system. They are compatible with all equipment makes and models and can protect air coils, air-handling units, cooling towers, louvers, and more.
Camfil Air Pollution Control has released its new line of HemiPleat® eXtreme nano fiber filters. The cartridge dust collector filters offer high filtration efficiencies and low pressure drop, and they are designed to withstand the rigors of pulse-cleaning for long life and reduced energy and operational costs.
Automatic Filters Inc. introduced its new line of ABW (automatic backwash) filters. The TEKLEEN® filters are useful for the HVAC industry, especially in cooling tower applications. The filters eliminate contamination caused by airborne dust, sand, pollen, algae, and pipe scales, thus reducing maintenance and operations costs.
With 10 LEED certified facilities and millions of additional square feet in the works, a well-known global Internet company committed to running green facilities was facing cooling and maintenance challenges at several of its data centers.
The company’s metal mesh filters and screens offer design engineers an alternative filter media for harsh indoor or outdoor applications by not only keeping dust and bugs out of equipment and critical cooling systems, but for EMI shielding and high heat applications.
Why was one floor’s laboratory ventilation failing to keep up, when it was even the closest floor to the rooftop fans? Some system sleuthing led two engineers to a fitting conclusion. Read more stories in May Issue 2017.
