4-inch Smart Gate

Smart Gates come with magnetic limit switches and an embedded processor that has Modbus communication capabilities for reading pressure at the gate, as well as air velocity and volume (which require calibration). They are designed to work with Ecogate's greenBOX Nxt and greenBOX Master control units for Smart Systems, where the power supply for the gates is provided by the greenBOX via the Ecogate Master Cable. Additionally, Smart Gates have an input for a workstation activity sensor.

Our heavy-duty, patented rotating blade gate is an ideal solution for industrial ventilation systems that require dust collection, fume extraction, or mist collection, such as those used in woodworking, food packaging, welding, and other general dust applications. Ecogate gates are designed to be the most robust, advanced, and energy-efficient industrial gates available, providing an automated and cost-effective blast gate solution. They're equipped with an industrial 24V DC motor for automatic operation and reliable magnetic limit switches. Compared to pneumatically operated gates, they're less expensive to install and operate, making them a smart choice for an energy-efficient and economical dust collection system. Rotating blade gates come in sizes ranging from 4" to 26" (with 14-26" available with a Purchase Order), and are available in both zinc-plated and stainless steel options (with Purchase Order) to suit various installation and design needs.

Material: Zinc-plated metal (stainless-steel gates are available with Purchase Order).

Duct System Mounting: Standard angle flanges (sold separately).

Seal: Plastic, the gate is sealed under negative pressure (created by ventilation fan).

Installation: Indoor-use only, use with negative pressure (not on positive side of the fan).

Opening/Closing Time: per table below (about 1 second per diameter inch) at 24V DC and zero pressure.

Maximum Operational Pressure: 27" w.c. (for higher pressure you may order Ecogate Butterfly-Style Gates).

Maximum Pressure Loss: 0.1 " w.c. (at 4,500 FPM).

Temperature Range: Motor 14° F to 113° F (-10° C to 45° C); with Mobilgrease 28 the temperature range is from -40° F (-40° C); plastic seal:  -200° C to 80°C, seal glue: -20° to 70° C.

Ingress Protection (IP): IP51.

Required Maintenance: A properly installed gate does not require maintenance (if the gate is not properly installed, dust can accumulate inside the gate body, and it will require cleaning by compressed air). Once per year it is recommended to test gate by using the greenBOX control unit.

Power Supply: (phoenix type pluggable terminal): 24V DC, 0.03 A without gate opening/closing; during opening/closing: 0.1 A (without pressure) - 0.9 A (under 27" w.c. pressure).

Indicators: Opening = Green LED flashing, Open = Green LED, Closing = Red LED flashing, Closed = Red LED.

On Board Indicators: Power, Sensor, Modbus, Error, Relay.

Motor Terminals: (phoenix type pluggable terminal): Modbus RTU over RS485, 19.2kBd, A(+), B(-) data signals; with overvoltage, and overcurrent protection.

Workstation Activity Input Terminal: (phoenix type pluggable terminal): Industry standard, optically isolated input; gate board is providing 24V DC, current 10mA (output from sensor can be dry contact or NPN transistor), Normally Open contact is the default, switchable to Normally Closed (by software).

Relay Terminal: (phoenix type screw terminal): The relay contact (max. 24V DC, 0.5A) can be used to connect to the workstation PLC to confirm that gate is open or ventilation is active (relay function is selectable via software).

Gates are used to close the ventilation drops at workstations that are not in operation. For best performance, connect to a greenBOX control unit to create an intelligent dust collection system.

Standard angle flanges are used to install the gate in the duct system (gate's angle flange mounting holes are both US and metric).

Adapters to install the gate to Nordfab's QuickConnect duct systems are available from Ecogate (with Purchase Order).

The gate body must be supported in the duct system to avoid pinching the rotating blade.

Install the gate in the straight section of duct, three duct diameters away from workstation hood or duct elbow (at both sides of the gate).

The rotating blade is equipped with magnets for both Open and Closed positions. The magnets are read by limit switches installed in a motor body.
