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 […]

Fix the Boiler in July to Limit Emission in the Winter
As the city’s apartment complex managers know all too well, New York City’s electricity rates are some of the highest in the country. Surprisingly, one of the biggest sources of energy usage for these structures is often the building’s boiler, which runs nearly continuously through the long, cold winter. That is why it’s not a bad idea to […]
Modbus Comms: How to Set Floating Point Values
In industrial settings, Modbus is one of the oldest protocols for devices to communicate their data digitally to a central controller. It allows transmitters to send integer data to controllers, and controllers to send integer data to SCADAs used in large, fully-monitored mission critical facilities such as data centers. Here we will give a pithy explanation of successfully […]
Boiler System 101: The Advantages of Full System Integration
Danbury, CT – A boiler system functions as a critical component to the continuous operation of a facility. It is important to maintain safe, reliable, and efficient operation while minimizing any downtime of the boiler system to prevent disruption of operation and significant loss.
