It may be springtime, but the Preferred Thermopump system is still a vital piece of equipment in a duplex fuel pump skid. When the temperatures fall, the Thermopump Fuel Oil Transfer Pump and Heater Set makes sure that diesel fuel is circulated and remains above its cloud point so it doesn’t get too cold and turn to gel. It’s an […]
Diesel Exhaust Fluid Systems: Reducing Emissions at Mission Critical sites
At Preferred, we are combining security and sustainable solutions at some of our highest security project sites, data centers and mission critical facilities, such as manufacturing centers. A global pharmaceutical manufacturing company bought generators and commissioned the Preferred staff of experienced and qualified engineers to design this Diesel Exhaust Fluid (DEF) system, pumping 300 gallons (of ammonia) per […]
Newly Upgraded Fuel Sentry, Leak Detection Controls with Renewable Fuel Burners
Made in the U.S.A. 🇺🇲 for renewable and sustainability goals, we provided these API-Ranger burners and upgraded controls for existing boilers. The Ranger burns three (3) fuels – ENSYN Renewable Fuel oil that’s an 85% carbon neutral non-fossil fuel, natural gas and #2 oil. It is also capable of burning Bio-Residual OilTM, a co-product of biodiesel production with minimal carbon density, and can […]
Choosing the Right Flow Meter – Vortex
-Robert Roda, Danbury, CT When it comes to choosing a flow meter engineers are spoiled with choices, making selection of the appropriate meter a daunting task simply due to the sheer number of possible types of measurement devices: differential-pressure, thermal mass, turbine, and vortex meters being among the most common. Vortex meters, however, offer some unique advantages and […]
The Preferred Design: Waterproof Pump Set for Continuous Power
Made in the U.S.A. to support nursing homes, hospitals, nuclear power plants, mission critical and data center installations: the Preferred Waterproof / Submersible Pump Sets for diesel fired E-Gen Systems and #2 oil fired boiler applications are patented, tested, and proven for continuous operation under more than 40′ of water pressure without leak. This design allows consulting and […]
How to make “Green Hydrogen” a Viable Solution for Reducing Emissions?
To move forward with plans for development in the face of the volatility of shared natural resources, many industries are taking a closer look at alternative fuels. Hydrogen, in particular, has amassed significant attention. “Green hydrogen” is a fuel created using renewable energy, and it has proven to be a valuable asset in transportation, manufacturing, and other energy-focused […]
Case Study: Integrating a Successful Fuel Oil System at University Hospital Complex
-David Eoff Preferred loves this system because the engineer contacted us early on in the design process and had the same goals Preferred has for a fuel system. He wanted a system that would be reliable, robust, redundant, and include the features Preferred has proven to work for large generator fueling systems like this one in Mission Critical, […]
Modbus RTU verses Modbus TCP/IP: What’s the Difference?
-Robert Frohock, Danbury, CT See also: “I know what Modbus is, but what is BACnet?” Modbus Protocol is a messaging structure developed by Modicon. It is used to establish master-slave/client-server communication between devices. Modbus has a lot of protocol options. But the two used most are Modbus RTU (Remote Terminal Unit), serial (RS-232 or RS-485) protocol or Modbus […]
