2” Gate for On-demand Central Industrial Vacuum Cleaning Systems

Updated: Mar 8

We’ve discussed the benefits of using Ecogate's Central Industrial Vacuum System.

Today we’d like to share with you the design of 2” or 3" butterfly gates for vacuum systems. This product is still in development, and the production of the first prototype is underway.

The Design

This gate design is using the same motor as all other Ecogate gates. The motors are available as “standard” (cost effective), or “smart” (controlled via Modbus). Smart motors allow for pressure, air velocity, and air volume readings. They also come with limit switches, which are readable from the control unit (greenBOX), measurement of motor current, supply voltage, and other diagnostic data. The smart motor is available with the pressure transmitter 24” w.c. (6 kPA), 40” w.c. (10 kPa), and 200” w.c. (50 kPa).

As seen from the drawings, the gate is very compact. With the exception of smaller gear, the remaining gate parts are the same as the larger butterfly gates that are already available. Depending on the demand, we can also design a 3” version (the butterfly gates are available as of today from 4” and up).

What Is This Gate Intended For?

First, this gate should be used in applications where the transported material does not create problems for the butterfly blades, for example, pharmaceutical factories. For larger dust volume and larger size of collected material, a rotating blade is more suitable.

The ideal use is when the vacuum system is connected to the production machine (tablet making machine, mixer etc.), and the gate is triggered to the Open position by the machine activity sensor. This allows the vacuum system to start/stop on-demand. In turn, this represents a huge system size reduction and huge electricity savings!

This gate can also serve as a bleed gate: most of the outlets of the vacuum systems are simple room outlet ports (valves). Users typically open the port, connect the hose for a room/workstation cleaning.

How to Maintain Minimum Transport Air Velocity

In on-demand industrial ventilation systems, the control computer (greenBOX) will open additional gates at drops that are not in use to maintain the minimum transport air velocity.

On the central vacuum system, this is not possible because manual room valves are used (and therefore the greenBOX computer cannot open them). Our solution is to use so-called “bleed gates”. They are installed at strategic locations at all branches of the vacuum system.

If only a few room vacuum drops are open and air velocity does not reach minimum transport air velocity, the control computer (greenBOX) will open one or more bleed gates, until minimum transport air velocity is reached.

The greenBOX Vac Pack

To support a faster and more cost-effective installation of an Ecogate system for Central Industrial Vacuum systems, we are introducing a new product: The greenBOX Vac Pack (EG.408) which allows you to connect sensors from eight room vacuum valves (or eight sensors from workstations connected to the vacuum system) while supporting pressure, air volume, and air velocity measurements.

Summary of Benefits of On-demand Vacuum systems managed by Ecogate greenBOX

Adding the Ecogate greenBOX control computer to manage your central industrial vacuum system will achieve significant electricity savings. The greenBOX will maintain minimum transport air velocities (and thus eliminate the danger of dust settling in the duct system). It also allows the use of a smaller vacuum pump while handling more room/workstation drops. On top of all of that, the electricity savings will contribute to your company's carbon footprint reduction.

Additional benefits include extended filter lifetime (if used), and reduced compressed air use for filter cleaning (if used), reduced system maintenance requirements, as well as access to a web interface with data and analytics showing details of the vacuum system’s performance.
