Our definition of "Giant" is continually evolving here at ebm-papst. Our new W3GZ50 series EC axial fan has a 1250mm (49.2 inch) blade diameter and is currently the world's largest diameter EC air mover with integrated electronics!
Just like the other products in our EC giant line up, this new axial fan was designed from the beginning to be energy efficient, simple to use and able to be installed in a variety of air moving applications. It can easily be customized by the end user so that it is a perfect match for use with refrigeration condensers, chiller applications or large scale ventilation applications. Its large size allows you to reduce the number of smaller fans used.
A complete fan assembly like the W3GZ50 series streamlines your purchasing and inventory requirements. The complete fan assembly has a motor, blade, venturi and finger guard that have all been designed to work together for maximum efficiency and eliminates the need to work with multiple vendors and patch together a fan assembly from various manufacturers. A complete assembly can simplify your production line by reducing wiring and installation time.
This air mover has an impressive list of features to match its size.
-Air performance- the direct drive motor and blade combination are able to produce over 38,000 CFM and can operate efficiently with backpressure levels of up to 0.8 inches of water.
-Factory balanced blade - the rotating motor and blades are balanced as a complete assembly on the production floor to insure a smooth operation.
-Accepts traditional control inputs - So that you can fully speed control this fan in your application, our integrated electronics will accept a variety of control inputs. For a simple set up, this means that you can use either a 0-10VDC input, 0-100% PWM input, or a 4-20mA input from an outside controller to completely vary the speed of the fan.
-RS485 Modbus RTU protocol ready - Many of the previously mute devices that are part of our daily lives are starting to become vocal whether we like it or not! Our cars, heating systems and even our home refrigerators are now capable of telling us what condition they are in with texts and e mails. Our lineup of EC Giants that are over 500 Watts are ready to be heard as well! If you would like this fan to be a vocal participant in your assembly, it is simple to establish two-way communication using the on board RS485 Modbus RTU protocol. Not only can you command it what RPM to run at, but you can obtain the run hours, the specific alarm status, internal motor temperature and many other bits of information that will keep you informed and up to date for critical applications. Our ongoing partnerships with key worldwide controls manufacturers make incorporating digital communication easier than ever before.
-Built in PID controller- for ultimate flexibility, our built in process controller allows you to program this unit to run independently without the need for a separate process controller to handle common field tasks. For example, when programmed to operate in closed loop sensor mode with your supplied temperature, pressure or other sensor, the fan will maintain a process specific set point. Simply set the sensor parameters and how quickly you want the fan to respond and the process controller will take it from there. The set point can be either entered using software to prevent unauthorized changes or from an accessible potentiometer for simple adjustments by anyone in the field. This powerful feature is a perfect way to reduce components in your overall assembly. Even if you choose to not use this feature as the main process controller, it can easily be programmed and can remain dormant in the background as a back up to the main process controller.
These are just some of the advanced features that this exciting new product has to help simplify your larger air moving projects.
We welcome you to come see this impressive fan and all of our equally advanced products on display at the AHR Expo in Dallas.
