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.

Considerations for Long Term Fuel Storage
–Joe Wallace, Danbury CT Many commercial and industrial facilities are required to have fuel oil bulk storage at their sites. Whether it is for heating applications or emergency power generation, the fuel must be available to use especially in mission critical operations, such as hospitals or data centers. If fuel oil is not your primary fuel or you […]
Automatic, Variable Ratio, Firing of a Blend of “Free” and Purchased Fuels
-Peter Lavelle, Danbury CT “Free” fuels are available from many processes: Digester Gas from wastewater treatment plants, Bio-Gas from agricultural and food processing plant waste, Hydrogen from chemical plants, Off-Gases from a Refinery, etc. The Challenge Firing these “free” fuels in a boiler, process heater, or engine-generator significantly reduces operating costs and can significantly reduce greenhouse gas emissions.
