Our SECOND burner and controls retrofit for Bates College on one of their existing 700 HP Cleaver-Brooks™ boilers so they can burn ENSYN Renewable Fuel Oil (100% renewable fuel source derived from trees) as their primary heating source! With our help, Bates is on the verge of reaching their 2020 emissions and carbon reduction milestones while increasing combustion efficiency and reducing electric consumption.

An innovative, low-cost combustion solution to meet sustainability goals, emission reduction requirements, and extreme efficiency improvements.

This installation is at an American college with aggressive sustainability goals. Our solution for them–a burner and controls upgrade on one of their existing 700 HP Cleaver Brooks boilers to achieve their emission and carbon reduction milestones, while increasing combustion efficiency and reducing electric consumption. This upgrade will NOT require the removal of the Cleaver Brooks front or rear doors, but acts as a direct replacement “insert” for the existing Cleaver Brooks burner, while reusing the existing Cleaver Brooks combustion fan and making no cuts or modifications in the original front door.

This specialized API-Ranger burner and controls upgrade will allow the college to burn ENSYN Renewable Fuel Oil, an 85% carbon neutral renewable fuel, along with natural gas or #2 oil.

American made and supported, our technological advancements continue to out-pace the competition.

 

For reliability, longevity and unmatched service, choose Preferred!

This Preferred JC-CDDF2 chief dispatcher model has been in service since the 1970’s in a Newport, RI facility. When one of the relay sockets finally broke, they called Preferred.

Although this unit has been out of production for nearly 20 years, we still had replacement parts in stock and original wiring diagrams for the installation of the new parts.

Built in the USA and built to last!

 

The Coen “AC” valve has been nearly irreplaceable because of it complicated, characterized design and expense – until now!

As just one of its capabilities, the Preferred Voluvalve directly replaced and exceeded the performance of the Coen “AC” valve at this recent project site.

The Voluvalve can be made to drop in as a direct replacement for a COEN “AC” valve or be used in a parallel positioning type control strategy as was utilized at this jobsite with our BurnerMate Universal Combustion Controller and Flame Safeguard System. 

Using a custom and proprietary drilled hole pattern inside the valve, it allows the valve to repeatedly, and accurately match the optimal efficiency flow rate, and fuel air ratio characteristics for any burner.

Designed and Manufactured in Danbury, CT USA and started up in the field, if requested, by our application engineers. Contact us for more information.

 

Preferred’s products and online tools can help Florida nursing homes and assisted-living facilities (ALF) meet state proposed fuel storage legislation.

After emergencies during and following Hurricane Irma, B 7028 and HB 7099 make permanent rules that require every nursing home and ALF in Florida to have emergency generators, keeping residents safe and their facilities functional at least until help can be sent to them after disasters. (Florida Governor’s statement)

The online tools provide a head start on emergency generator system design and planning. Our fuel load web tool calculates main tank storage size based on generator kW.

We offer a web tool to check suction conditions and size fuel oil pumps and piping systems here:

And finally, you can generate a complete Facility Fuel Oil specification section based on Preferred products.

Preferred’s ATPSF duplex pump sets include integrated pump controls and optional tank gauge and leak detection systems. We also offer day tanks, return pumps, fill boxes, and all the accessories to make a complete fuel oil handling system.

Although our engineers can custom design a system for any number of generators, our standard pump control program can handle up to two-day tanks and up to two main storage tanks right out of the box. With no programming and minimal engineering required, these systems are available with very short lead times.

Contact us to speak with an experienced Preferred engineer.

Preferred is bringing something BIG to the industry! 

Tired of fuel and electric waste? Want a more reliable system that also meets strict emissions standards? You know you need to upgrade, but the installation time and expense of a modern linkageless control system often just isn’t plausible…Until now.

Preferred’s new flexible solution dramatically cuts the cost and time for a linkage to linkageless control system retrofit. Now, you don’t have to upgrade your whole boiler room in order to have modern linkageless control. 

So, what do you get? A deal on a modern efficient system, significant fuel and electric savings and rebates, and an intuitive system that will keep you ahead of any emergencies.

 

It’s the flexible retrofit solution…It’s the FlexFit.

 

 

Preferred’s Fuel Oil Handling and Boiler Control Cabinets now have California’s OSHPD Seismic Preapproval. This certification, required by the building code for all hospitals and large nursing facilities in California, verifies the integrity of manufacturer’s equipment and components in event of a seismic disturbance, an earthquake. Through “shake table testing,” Preferred’s boiler and fuel oil handling panels have received the certification that proves its functional ability survive an earthquake and keep your facility running.

 

Top tier American college chooses Preferred Utilities as their partner in a major burner and controls retrofit project on their existing (700 hp) Johnston Boiler. With the installation of the dual fuel Preferred Utilities API-InjectAire burner, the college will reduce its electric consumption on this unit by more than 75% while increasing combustion efficiency by more than double.

With the new ability to have Low NOx 10:1 turn down on natural gas and 8:1 turn down on oil along with precise draft control, and O2 trim, greenhouse gas emissions will be significantly reduced along with wear and tear on the boiler.

We manufacture in the USA and provide single source responsibility for burners, fuel trains, combustion controls and factory start up.

 

The PCC-IV loop controller is the next generation of Preferred’s loop controllers AND upgraded technology for the entire industry. The PCC-IV is more flexible, has extensive memory, and not only replaces the Preferred PCC-III, but also can replace the Siemens Moore 352 and 353, obsolete and no longer supported starting October 2017.

Preferred Utilities’s controls are just that- preferred. Consider a case study of a longtime PCC controls customer:

Preferred Utilities has been supporting this facility in New York since 1988 with our PCC II and III loop controllers. This site installed one PCC-IV and is now considering this next generation of upgrade, the PCC-IV, in their plant with four (4) 50kpph boilers, each with steam, gas, and oil flow meters.

In 1988, the facility installed 16 PCC-IIs and 5 control panels, plus field instruments for a burner/controls upgrade. Almost 10 years later in 1997, they updated the system with the purchase and installation of 17 PCC-IIIs. In 2002, they decided to upgrade again and add O2 trim. Satisfied with the Preferred product, they installed 21 of the PCC-III units.

Now, in 2017, the plant installed a PCC-IV in parallel with one of the PCC-III controls to observe the performance and is considering upgrading the rest of the PCC-II and PCC-III controls. With the auto-converting functionality of the PCC-IV, the existing PCC-III programs can be re-used without modification and re-programming.

Preferred Utilities is pleased to offer generations of quality products that age gracefully and come with a pledge of full service support and solutions for upgrades in the future.

A New Jersey paper mill came to Preferred Utilities recently needing a quote for a new burner for their 1961 Preferred Utilities Unit Steam Generator. What is wrong with their existing Preferred burner? Nothing. The plant is being forced to convert from No. 6 heavy fuel oil to natural gas.

Will their next burner last 56+ years? Maybe. It depends on who they buy it from.

Note, Preferred still had the documentation on the existing burner and boiler. But we had to go to 49 year Preferred veteran engineer Ricky Erickson to find it.

This plant needs a Low NOx burner that meets the emissions regulations in New Jersey. Preferred designs and builds burners that can meet the strictest regulations, and provides configurable NOx settings, “future-proofing” them against lower emissions requirements that states may adopt in the coming years.

Built for the environment. Built to last.
