greenBOX Controller

Intelligent Airflow Management


What is an Ecogate greenBOX?

The brain of the Ecogate system, the greenBOX, is a state-of-the-art control unit designed to optimize your dust collection, fume extraction, or mist extraction system resulting in electricity savings of 50% to 75%. The system is designed to be fully automated, so users are expected to just use their workstations. 


The greenBOX control unit manages the entire dust collection system: it opens and closes workstation gates, starts and stops ventilation fan(s) and dust collectors, adjusts the fan(s) speed via Power Master VFD, and maintains minimum transport air velocities in the duct system.


By utilizing real-time air velocity, volume, and pressure measurements, it continuously monitors your machines' activities to determine the airflow requirements. Air velocities, volumes, and pressures are measured at gates, calculated at branches, and assessed at the system level. The greenBOX control unit automatically maintains minimal air flow velocities throughout your system to prevent material settling in your ducts. 


With the greenBOX, you can rest assured that your industrial ventilation system is running at optimal levels, saving you a lot of money on fan operation costs and on makeup air if you are using heating and/or air conditioning.


Outperforms the Competitors and Market Price

The new generation of greenBOX control units are the most powerful, flexible, and energy-conserving option for on-demand dust collection systems available today, all at a budget-friendly cost.

You won't find anything remotely as advanced as our greenBOX control units at a similar price range–not even close.

Modern Display & User Interface

  • State-of-the-Art OLED: Equipped with premium OLED technology known for rich colors and high contrast, the greenBOX Max and Master models feature a 15.6" screen with a brightness of 350, while the greenBOX Nxt model sports a 10.1" screen with a brightness of 300.

  • Energy-Efficient: Paired with a dark user interface, OLED displays offer low power consumption, a key advantage over traditional LCD panels that require constant backlighting.

  • Extended Lifespan: Automatically turns off after a few minutes of inactivity, extending the lifespan of the display.

Safety & Security

  • Minimum Transport Air Velocities: Measures air velocity at the gates, branches and main duct and adjusts in real-time.

  • NFPA Compliant: National Fire Prevention Association mandates that control systems must ensure minimum airflow requirements throughout the entire duct system.

  • Image-Based Updates: Utilizes image-based system updates that are cryptographically signed and verified, ensuring the integrity of what's running on each system.

  • Auto Security Updates: Configuration-as-code automatically fetches and installs security updates for the OS and third-party software.


Cutting-Edge Software

  • Limitless Capacity: Capable of managing many dust, fume, or mist collection systems–only limited by power supply capacity for the gates, and number of Modbus ports available.

  • Open-Source Reliability: Runs on Ubuntu Linux, a stable and flexible open-source OS widely used in industrial automation and control systems.

  • Over-the-Air Updates: Uses Mender for delivering over-the-air updates, ensuring OS and application reliability. Features automated rollback in case of update failure.

  • Modular, Containerized Software: Uses Docker for resource-efficient, secure application isolation and quick updates, complemented by ZeroMQ for streamlined inter-module communication.

Data Analytics & Intelligent Integration

  • Active Workstation Utilization: Continuously collects and analyzes data on electricity savings and workstation activity, enabling month-to-month comparisons and workflow optimization.

  • In-Depth Reporting: Provides a daily email report detailing system performance metrics such as filter losses, fan pressure, air volumes, and velocities, offering insights beyond basic dust collector monitoring.

  • BAS Compatibility: Seamlessly integrates with Building Automation Systems (BAS), offering a user-friendly interface and real-time updates on ventilation system performance, warnings, and errors.


Which greenBOX Should You Buy?

We offer four different greenBOX models to meet the needs of various industrial ventilation systems - from small shops up to large factories with multiple systems. Our team of experts can help you determine which greenBOX model is best suited to your specific requirements, ensuring that you get the most out of your investment.

Legacy greenBOX 12

The greenBOX 12 stands as a proven, cost-effective solution for managing up to 12 workstations. Designed for those who seek both performance and economy, this legacy unit has the capability to maintain minimum airflow in one duct zone and can be paired with the Power Master VFD for optimal fan control. With over twenty years in production, the greenBOX 12 has seen numerous improvements, cementing its reputation for reliability. As part of Ecogate's enduring product lineup, it continues to be the most budget-friendly standard system available in the market.


greenBOX ONE

greenBOX One

The Ecogate greenBOX ONE is designed to bridge the gap between an Ecogate Smart System and third-party gates (such as pneumatically operated gates). If you have CNC machines with built-in butterfly gates or pneumatically operated automatic blast gates installed in your duct, the greenBOX ONE allows you to integrate them seamlessly with your Ecogate system.


While the greenBOX ONE cannot control third-party gates directly, it serves as an input to the Ecogate smart system, informing it when a particular machine requires ventilation. The greenBOX ONE reads information from the external gate and sends it to your greenBOX controller, which adjusts the fan speed to deliver proper airflow to that specific machine and throughout the system.

With the same pressure sensing tube as Ecogate's Smart Gates, the greenBOX ONE can also read volume, velocity, and pressure at the specific gate, providing advanced control and monitoring capabilities. 

greenBOX ONE

greenBOX 8

The greenBOX 8, introduced in 1999, was designed to help woodworkers with a dust collection system in their shop reduce their electricity bill. Capable of handling up to 8 workstations, this system provided on-demand ventilation while maintaining appropriate airflow velocities.


The greenBOX 8 is no longer available, as it is now considered 'prehistoric' in the realm of technology development. The great news is that it has been replaced by the newer greenBOX 12, offering even greater flexibility, reliability, and performance.
