Fluid-side economizers (or water/economizer fluid) – these use heat exchange between exhaust or waste heat fluids and process or feed fluids (e.g. boiler feed water, chilled water, or glycol systems).
Air‐side economizers – these draw ambient cooling air when conditions permit, reducing mechanical cooling workload.
By Boiling or Heat Recovery Efficiency (sometimes referenced as condensing vs non-condensing in some applications):
Higher efficiency condensing or optimized heat recovery economizers capture more heat from exhaust, etc.
Non-condensing economizers which are simpler, often less costly, but may deliver lower efficiency improvements.
By Application:
Power Plants – especially thermal power plants, where boiler exhaust heat or flue gases can be used via economizers to preheat feed water, thus improving plant efficiency.
Boilers in industrial and commercial settings.
HVAC systems in commercial and large residential buildings.
Refrigeration systems where ambient air or waste heat can reduce compressor work, or in food beverage and cold storage sectors.
Data Centers which need efficient cooling; economizer solutions (air-side or fluid) help reduce reliance on chillers or CRAC units under certain conditions.
By End-Use Industry:
Industrial sector – heavy industry, manufacturing, power generation, etc., where large boilers or heating/cooling systems are used.
Commercial sector – buildings, retail, offices, shopping centers, hospitality, etc.
