Understanding Trane Economizers

What Is an Economizer?

An economizer is a device that allows a building’s HVAC system to use outside air for cooling when conditions are favorable, reducing reliance on mechanical cooling systems like air conditioners. By leveraging outdoor air efficiently, economizers contribute significantly to energy savings and improved indoor air quality.

Types of Trane Economizers

Trane offers various economizer models tailored to different building requirements:

• Air-Side Economizers: Introduce outside air directly into the ventilation system.
• Water-Side Economizers: Use cooling towers and heat exchangers to reduce mechanical cooling needs.
• Hybrid Economizers: Combine both air-side and water-side features for optimal performance.
