Commercial HVAC Economizers Built for Rooftop Systems

MicroMetl designs and manufactures commercial HVAC economizers engineered for seamless integration with rooftop units, improving energy efficiency and ventilation performance.

MicroMetl Economizers

Our solutions support contractors, engineers, and distributors with precision-built products that meet evolving energy codes and real-world application demands.

An economizer introduces fresh outside air into a building in a controlled manner, using favorable outdoor conditions to reduce mechanical cooling load and improve overall system efficiency. By leveraging temperature differentials and coordinated components—such as dampers and sensors—economizers provide intelligent free cooling while supporting compliance with ASHRAE and IECC standards.

MicroMetl offers vertical, horizontal, and convertible economizer configurations to match a wide range of RTU applications. Each unit is designed and manufactured in the United States using precision fabrication and rigorous quality control standards, ensuring consistent performance, accurate fit, and long-term reliability in the field.

Whether you’re specifying a new system or upgrading an existing unit, our focus is on delivering application-ready solutions—economizers that integrate seamlessly with RTUs, meet code requirements, and arrive ready to install with confidence.

FAQs: HVAC Economizers

Find quick answers about MicroMetl HVAC economizers, customization options, and product performance.

An HVAC economizer is a ventilation control device that uses outdoor air for cooling when conditions are favorable. By reducing reliance on mechanical cooling, it improves energy efficiency and supports indoor air quality in commercial buildings.

An economizer monitors outdoor air temperature or enthalpy levels and automatically adjusts dampers to introduce fresh air when it can provide cooling. This process reduces compressor runtime and lowers energy costs.

Yes, many commercial energy codes such as ASHRAE and IECC require economizers on rooftop units above specific capacity thresholds. Requirements vary by climate zone and application.

MicroMetl offers three different orientations: Vertical, Horizontal & Convertible.

Economizer controls optimize damper operation, monitor environmental conditions, and ensure compliance with ventilation standards, resulting in reduced energy consumption and improved system performance.
