Rosenberg EC Fan Grid Retrofit Solutions

Continuous and consistent airflow is essential to virtually every facility, making under-performing or unreliable fans simply unacceptable. In addition to reliability concerns, inefficient fans can be a building’s biggest energy consumer. Given the increasing cause for environmental concern, designers should look to select EC plug fans which will not only provide the necessary reliability, Inefficient belt driven fan, as installed in most of the older air handling units but also provide optimum efficiency and environmental benefits. In most fan systems a single fan EC-TECHNOLOGY is selected for the required system and various methods of control are also installed to meet other operating points defined by the system duty such as dampers or variable pitch blades.

In some instances, it is advantageous to use more than one fan in a system, for example when it is necessary for the required operating range of the system to include multiple plug fans running closer to their peak efficiencies, instead of one large fan controlled over wide operating range. Multiple fans for capacity control may be more economical if the cost of operation is critical. By running fans in parallel, when one motor fails, only a portion of the airflow is lost, unlike single fan air handlers.

An ECFanGrid consists of several modular backward curved centrifugal fans or plug fans arranged in a grid construction offering numerous advantages overconventional technology. It is equally suitable for new projects and as a replacement for large single fans in retrofit air handling units. In addition to being compact and flexible, the ECFanGrid is easy to clean, replace and maintain while expelling low noise and deliveringuniform air stream. A uniform air stream improves the replacement of e.g. older belt driven fans.

The efficiency of other downstream components, for ECFanGrid Retrofit KIT includes all mechanical example, a thermal wheel. parts: fans, cabinet, grid and screws.

Global Plasma Solutions Is The First Air Purification Solution To Test SARS-CoV-2, Achieving A 99.4% Reduction Of The Surface Strain Within 30 Minutes

Global Plasma Solutions, the leader in Indoor Air Quality, announced today industry-leading ionization testing results, demonstrating a 99.4% reduction rate on a SARS-CoV-2 (COVID-19) surface strain within 30 minutes, the first instance in which an air purification company has effectively neutralized SARS-CoV-2. Following initial testing of coronavirus 229E in March 2020, Global Plasma Solutions utilized its proprietary needlepoint bipolar ionization to inactivate SARS-CoV-2T. he study was jointly executed with Aviation Clean Air.

In this laboratory study, Aviation Clean Air designed a test to mimic ionization conditions like that of a commercial aircraft's fuselage. Based on viral titrations, it was determined that at 10 minutes, 84.2% of the virus was inactivated. At 15 minutes, 92.6% of the virus was inactivated, and at 30 minutes, 99.4% of the virus was inactivated.

"The testing results we achieved through our proprietary needlepoint bipolar ionization technology clearly demonstrate that Global Plasma Solutions is the gold standard in air purification," said Global Plasma Solutions Founder and Chief Technology Officer, Charles Waddell. "For any kind of facility from commercial buildings to aircrafts, delivering the cleanest, safest indoor air environment will only become increasingly more important, and our ozonefree technology is one of the most sophisticated products on the market."
