With our cutting-edge solutions, achieve peace of mind while ensuring accurate and reliable measurements in your operations.

Fast and Reliable Solutions for Optimal Efficiency

We offer two types of calorimeters:

“Injection-style” zero-hydrocarbon emissions calorimeters:   Used in research and development, quality control, and compliance testing in the petrochemical, automotive, and energy industries. They provide a precise and reliable method for measuring the energy content of various fuels and other combustible materials without contributing to air pollution or other environmental concerns.

Continuous “direct” calorimeters: Used in industrial and commercial settings, such as power plants, refineries, and chemical production facilities, to monitor the energy content of the materials being processed and optimize the efficiency of the production process. By continuously measuring the calorific value of the material, operators can adjust the process parameters in real-time to minimize energy consumption, reduce waste, and improve product quality.

  • Flare Gas Monitoring & Flare Gas Control Solutions

    On December 2, 2023, the U.S. Environmental Protection Agency (EPA) revealed its conclusive regulation aimed at significantly slashing methane and air pollution emissions originating from oil and natural gas operations. This comprehensive final measure, spanning over 1,600 pages, encompasses enhanced and updated standards for methane and other air pollutants from new, modified, and reconstructed sources. Additionally, it provides emissions guidelines to aid states in formulating plans aimed at curbing methane emissions from existing sources.  Download the EPA Factsheet

    Fuel gas monitoring is the process of measuring and analyzing the composition and quality of fuel gas used in industrial processes. Fuel gas is commonly used in a variety of applications, such as furnaces, boilers, and turbines. Fuel gas monitoring is important because it helps ensure that the fuel gas being used is of the appropriate quality and composition for the intended application.  This involves the use of gas analyzers that measure the concentrations of various gases in the fuel gas, including methane, carbon monoxide, hydrogen, and other hydrocarbons.  Fuel gas monitoring is important for several reasons, including:

    • Safety: Monitoring fuel gas ensures that it is not contaminated with harmful gases, which could create hazardous conditions during combustion or release toxic emissions.
    • Efficiency: The quality and composition of fuel gas can impact the efficiency of industrial processes. Monitoring helps to ensure that the fuel gas is of the appropriate quality and composition to achieve optimal performance.
    • Regulatory compliance: Regulations often mandate the monitoring of fuel gas to ensure that it meets specific quality and composition standards.
    • Cost savings: Monitoring fuel gas can help identify opportunities to improve efficiency and reduce waste, which can result in cost savings for industrial facilities.
