What is Condensing Economizer?

Condensing Economizers improve the thermal efficiency of boilers by cooling the exhaust gas below its dew point (about 135°F for combustion products of natural gas) and recovering the latent heat of water vapor through special designed heat exchanger units.

How Condensing Economizers Saves-Energy?

Hydrocarbon fuels produce considerable quantities of water vapor as a combustion byproduct. When one molecule of methane (the main constituent of natural gas) is combusted, it releases two molecules of water vapor. In other words converting to pound/mole, every pound of methane produces 2.25 pounds of water vapor.

CH4 + 2O2 → CO2 + 2H2O


  • High energy efficiency
  • Minimum maintenance
  • No need a direct supervision
  • Easy installation
  • Control remotely by PLC & HMI
  • Produces water


  • Textiles
  • Commercial Laundries
  • Food and beverage Breweries
  • Large Hospitals
  • Non-integrated Paper Mills
  • Green Houses
  • District Heating
  • Buildings Heated by Steam or Hot Water

Save Energy, Save Nature

This technology lowers energy consumption and GHG (Greenhouse Gas) emissions significantly because of utilizing the latent heat in the flu gas and returning the heat to the system. Therefore, Condensing Economizers integrate energy savings and GHG reduction goals at the same time. Considering new regulations by environmental agencies (such asAB 32 and Carbon Footprint issue), reduction in energy expenditures and GHG emission will lead to product cost reduction and become an imperative source of competitive advantage for your corporation. By utilizing Condensing Economizers, your company can enhance steam and hot water system efficiency overall heat recovery by up to 10%.
