greenBOX 12

This greenBOX can fully automate your shop's dust collecting system so it starts when the first workstation is in operation, directs dust extraction to only active workstations, and shuts down after the last workstation is turned off.

This level of automation and optimization results in not only more time on your hands from less manual operation, but also high energy savings. The more energy saved, the more money in your pocket and of course, the better the environment. Having your system not run at full capacity will lower the noise level in your shop, which very often results in boosted morale. Closing the gates to non-active workstations means the same dust collector can serve more workstations.

The greenBOX 12 is often used in shops but it can also thrive in an industrial setting. It is compatible with our heavy-duty gates (4"-26" with Standard Motors) and connects with the Power Master VFD , via Modbus communication, to adjust the speed of the fan (includes on/off delay). It maintains minimal airflow per NFPA safety standards.

Incentives for installing energy-efficient control systems are available from many power utilities. The electricity savings are high (typically 66%), based on the law of physics called "affinity law" or "fan law".

Note: if your shop/factory is using more than 12 workstations you have two options to expand. Option 1 is to get a second greenBOX 12 and wire it to the first as Master/slave connection. Option 2 would be to upgrade to a bigger greenBOX control unit, with data collecting, data analysis, and remote access.
 

Model: greenBOX 12

Firmware: Firmware is user updatable from the “Ecogate greenBOX 12 Setup & Monitoring Software”

Size: Approx. 10” x 14” x 3” (254 mm x 356 mm x 76 mm), green painted metal type 1 enclosure intended for a wall installation.

Weight: Approx 6.0 Lb (2.8 kg)

Power Supply: Power supply notebook style adapter 115V-230V AC, 50-60 Hz, 40VA max.; 24V DC 2 Amps is included. Baseline consumption is 6W (0.15 Amps, 8VA); consumption will increase to 12W with one gate opening /closing, to 18W with two gates moving.

Ecogate Compatibility: Ecogate Standard Gates (4” to 26”) are compatible. 12 channels for gates/sensors (power supply 24 V DC for gates is provided from greenBOX); up to two gates operated at a same time can be connected to one output.

LED Indicators & Monitoring: INPUT SIGNAL (signal from sensor) LED yellow lights (12x), GATE OPEN status green LED lights (12x), POWER supply LED light, FAN RUN LED light, BYPASS LED light, SECURITY LED light, COMM (PC communication) LED light; all indicators are on board (inside greenBOX 12 enclosure); status can also be monitored via Windows PC connected via serial channel (up to 50 ft cable) with “Ecogate greenBOX 12 Setup & Monitoring software”. The USB to serial adapter is used to connect greenBOX to the Windows notebook.

Accessories (optional): Ecogate Standard gates 4” to 26”, Ecogate VOLT or current sensors, Ecogate Power MASTER variable frequency drive from 10 to 400 HP fan motors, Ecogate Standard and Sensor cables.

Inputs: Sensor input for each gate (if the input is active, the gate will be open; inputs are selectable as a contact 24V DC input or input for sensor with open collector); Input for “BYPASS” switch to open all gates and start dust collector; “SECURITY” input for connecting any customer securities; VACUUM INPUT for standard fan pressure transmitter 4 -20 mA.

Outputs: Free (dry) RUN contact to start/stop variable frequency drive (or fan via optional contactor if VFD is not used); START and STOP (dry contacts to start/stop dust collector, pulse about 1 sec. can be wired in parallel/series with the Start/Stop buttons of dust collector control); analog output (4-20 mA) to adjust fan RPM via variable frequency drive (if VFD is used); output for the twelve motorized gates (+24V DC for gate opening, -24V DC for the gate closing).

Settings: (Windows software and cable are delivered with the system). Settings using Windows PC with Ecogate "greenBOX Setup & Monitoring" software connected to greenBOX via USB to serial cable: gate timings (on delay, off delay), gate diameters, minimum airflow to maintain transport air velocity as a percentage of total air volume, negative pressure compensation (for the workstations at the end of ducting) as a percent of the fan RPM, dust collector on delay (0-99 sec) and dust collector shut-off delay (0 to 99 minutes), variable frequency drive minimal and maximum RPM, security functions (configurable in setup: all gates can be open or closed in stop mode, the fan can stop or start if security input is open), CLEANING function (to sweep duct in regular intervals, or at system stop), and INACTIVITY time after power up.

The dust collector can automatically be started via the contactor (magnetic starter - not included) or via the recommended Power Master Variable Frequency Drive (VFD).

For a complete system you need a greenBOX control unit, Ecogate Standard gates of proper diameter for all workstations, Volt or current sensors for all workstations, Power MASTER Variable Frequency Drive (preferably), Ecogate Standard Cable to connect the gates to the greenBOX, and Ecogate Sensor Cable to connect sensors to the gates. For initial setup the Windows notebook is necessary (notebook can be disconnected from greeenBOX after setup).

The system is designed to be fully automated, so users are expected to just use their workstations.
