David Bohn, of Redding, CT, serves as president and CEO of Preferred Utilities Manufacturing Corporation in Danbury, CT, after a time as district sales manager and marketing coordinator with the company. In his work there, Redding resident David Bohn has helped with the energy needs of a number of facilities, including Abington Memorial Hospital in Pennsylvania.

When a major winter storm struck the Northeast in March 2018, it was an emergency backup energy system designed and installed by Preferred Utilities Manufacturing Corporation that allowed Abington Memorial to keep running. When such storms arrive, power can be lost for extended periods, and keeping emergency generation equipment fueled and operating can be a challenge. At a hospital, it can literally be a matter of life and death.

Preferred Utilities created a backup system comprised of underground storage tanks, pumps, delivery mechanisms, and other equipment necessary to immediately take over operation when commercial power was knocked out. Because the emergency system was in place, the hospital was able to continue providing patient care without any lapses.

David Bohn, a Redding, CT, executive, heads Preferred Utilities Manufacturing Corporation, a firm that provides coordinated power plant equipment manufacturing and engineering services. David Bohn and his team in Redding, CT, are experienced in enabling industrial and residential facilities to meet federal, state, and municipal mandates related to emissions and energy efficiency.

One of Preferred Utilities’ success stories involved the installation of a low-emissions, high-efficiency API Inject-Aire burner within the New York City Housing Authority’s (NYCHA) Stapleton Houses. This innovative system brought a solution uniquely capable of meeting strict carbon footprint reduction mandates outlined in New York City Local Law 87.

The burners have the capacity to decrease electricity consumption by up to 85 percent, compared with previous generation burners. The pre-purge and post-purge cycles associated with such burners have been reduced by more than half, with systemwide thermal shock wear and tear decreased a corresponding amount.

A distinct advantage of Preferred Utilities’ low-emissions technology is that it enables facilities to quickly and cost effectively upgrade to ultralow-emissions technologies as they come online. More opportunities for replacement exist, as a number of the company’s burners approach 50 years of service within the NYCHA and New York City Board of Education.

Preferred Utilities’ Efficiency Efforts at Ohio Air Force Base

David Bohn is a Redding, CT, executive who directs Preferred Utilities Manufacturing Corporation as president and offers a host of energy-efficient products ranging from industrial boilers and burners to combustion controllers. David Bohn and his Redding, CT, team oversaw a major coal-to-natural-gas boiler conversion process that reflected a 2012 mandate for the Wright-Patterson Air Force Base to be brought under new U.S. Environmental Protection Agency emission limits.

The Dayton, Ohio, base has historically operated using coal- and natural-gas-fired boilers. The coal-fired boilers did not come in under new Maximum Achievable Control Technology (MACT) standards in areas such as particulate and mercury. With compliance deadlines fast approaching, major conversions of two coal-fired boilers were initiated, as well as the conversion two coal-powered high-temperature-hot-water (HTHW) systems. The other units were planned for demolition.

When completed, the upgrades significantly decreased pollutant emissions and reduced the amount of carbon dioxide released by 50 percent. With the boiler modifications having completed last year, they are now fully operational and helping meet sustainability goals.

Preferred Utilities Completes Emissions-Reducing WPAFB Plant Retrofit

David G. Bohn is a Redding, CT, executive who guides Preferred Utilities Manufacturing Corporation as president. His firm emphasizes energy efficiency in its manufactured products, which encompass industrial oil and gas powered boilers and burners as well as combustion controllers. David G. Bohn and his Redding, CT, team have completed a number of high profile projects including a coal-to-natural-gas boiler conversion assignment at the Wright-Patterson Air Force Base (WPAFB).

Located in Dayton, Ohio, WPAFB faced a significant challenge in meeting new US Environmental Protection Agency “Maximum Achievable Control Technology” regulations, which lay out boiler emission limits. In particular, a pair of central heating plants needed to be modified from coal-firing technologies to incorporate natural gas, which burns more readily.

The Tulsa-based Preferred Special Combustion Engineering (PSCE) division completed retrofits on a variety of plant assemblies, from burners to fans, and undertook extensive performance testing. The late 1970s steam boilers were finally able to meet the temperature, pressure, and output indicated on their original nameplate. In addition, the PSCE solution was successful in reducing emissions of greenhouse gases by one half to within mandated levels.
