GreenTrol Automation

reenTrol Automation develops integrated thermal dispersion airflow, temperature, occupancy, and CO₂ measurement and control solutions for light commercial HVAC applications.

Designed specifically for packaged rooftop units, heat and energy recovery ventilators (HRVs/ERVs), and round duct systems, GreenTrol products help optimize ventilation, improve indoor air quality (IAQ), enhance occupant comfort, and reduce energy consumption.

Our integrated solutions combine accurate sensing technology with application-specific controls to simplify demand control ventilation (DCV), outdoor air control, occupancy-based ventilation, and building automation system (BAS) integration. By measuring critical HVAC parameters and responding to real-time conditions, GreenTrol helps building owners, engineers, contractors, and OEMs improve building performance while reducing operating costs.

Founded in 2009 by a group of EBTRON investors and designers, GreenTrol is backed by more than 30 years of experience in thermal dispersion airflow measurement and controls. Our products are engineered to deliver reliable, cost-effective ventilation control solutions for smaller commercial HVAC applications where simplicity, performance, and value matter.

From airflow measurement and outdoor air control to occupancy-based ventilation and energy-efficient operation, GreenTrol provides practical, single-source solutions for healthier, more efficient buildings.
