History

The Preferred Utilities Manufacturing Corporation was founded in 1920 by oil heating engineers who foresaw the demand for accessories designed especially for oil burning and handling applications.

Preferred Utilities Manufacturing Corporation

In 1920, “Preferred Utilities Manufacturing Corporation” was founded and began as engineering based supplier of Oil Burning and Fuel Oil Handling Accessories. This service was immediately accepted and its continued success confirms customer satisfaction.
In 1946. A new and modern manufacturing plant, located in Danbury, CT was completed. This new plant enabled Preferred to expand its manufacturing capability and provide its customers with higher quality standards.
From 1946 to this day, the work of responding to the requirements of commercial, institutional, industrial and utility plants continues. Today, Preferred engineers are designing equipment for use during Nuclear Power Plant outages, new and improved Emergency Diesel Generator fuel transfer pump sets and instrumentation and complete combustion systems for hot water and steam generating plants. Preferred is dedicated to developing products that will help our customers reduce operating costs, improve plant flexibility and meet emissions requirements. Consult the Factory with your custom engineered product requirements.

Fuel Oil Handling Systems

Since 1920, Preferred has been actively and prominently identified with the oil burning industry in all its phases. Over the years the company has been developing and manufacturing new and advanced fuel oil pump sets and accessories.
Since 1989. Preferred has been providing fuel oil transfer system single source responsibility by packaging together its pump sets, day tanks, tank gauges and accessories with sophisticated microprocessor-based control and monitoring systems.

Burners/Boilers

In the war years of 1940, Preferred served the war effort by developing and manufacturing new and advanced automatic No. 2 through No. 6 fuel oil and natural gas burners.
In 1941, Preferred designed and produced its first factory packaged four pass down draft fire-tube boiler with integral burner, controls and accessories. Production of the “Unit Steam Generator” continued for 30 years.
In 1972, W.N. Best Combustion was purchased, bringing in a line of heavy industrial and specialty waste burners.
In 2001, W.N Best Combustion retrofitted its first XPlus Combustion System to a 20,000 pph water tube boiler. Using our unique design focus and capability, this burner system achieves and maintains high efficiency and low emissions.

Instruments and Controls

In 1964, Preferred purchased the instruments division of General Controls, Inc. adding draft, fuel gas temperature, and boiler lead/lag control product lines to the company’s Catalog.
In 1972, Preferred installed its first digital combustion control system. These controls were part of a series of retrofit projects wherein Preferred engineered, designed, and manufactured a complete and integrated package of burners, flame safety systems, pump and heater sets, sensors and controls.
In 1978, Preferred purchased Rimcor Instruments and their line of analog combustion and oxygen trim controllers. Preferred-Rimcor Instruments then began the design and production of microprocessor-based boiler efficiency instruments, controls and digital oil tank gauges.
Since 1982, Preferred has designed, manufactured and commissioned microprocessor-based controllers, Supervisory Control and Data Acquisition Systems (SCADA), boiler monitoring instruments and actuators. This equipment has been installed on thousands of boilers and in hundreds of process plants.

Nuclear Industry

In 1980, the Preferred Engineering division was formed to service the nuclear industry with tools and services that speed and improve the safety of outage activities.

Complete Combustion Systems

Today, Preferred is a trusted supplier of Burners with a unique ability to provide single source responsibility. The key to Preferred’s Burner offering is not the Burner, rather that it has been designed to be an integral part of a Controls, Flame Safety System, SCADA and Fuel Handling system performance package. In other words we have a package that demonstrates the fact that the “whole is greater than the sum of its parts.”
