Application engineering note

Centrifugal fan mounted on a rectangular support frame
Representative framed centrifugal fan; model and application details are listed below.

EC centrifugal fans can be assessed for data center air-handling units where the design requires controlled airflow through coils, filters and the discharge path. The enquiry needs the equipment operating points and interfaces before a particular fan can be selected.

Choose a documented fan configuration

LONGWELL’s LWBE family uses backward-curved centrifugal impellers and includes EC motor configurations. Its plug-fan form is intended for integration with an air-handling enclosure. The motor’s electronic drive and the fan’s mechanical arrangement should be specified together.

Provide the required airflow and static pressure for each cooling mode, with the coil and filter conditions used in the calculation. Where several fans operate in one unit, include their layout and the required sequence when an individual fan is stopped or removed for service.

Confirm electrical and mechanical interfaces

Use the exact model’s wiring and control specification to identify mains input, speed command and status connections. State the expected response to a lost control signal and the available controller interfaces.

The mounting review should include inlet geometry, fixing points, cable routing and fan removal space. Confirm the airflow and thermal acceptance checks for the complete cooling equipment during the design review. These define what the assembled system needs to demonstrate under its intended operating conditions.

Discuss your fan requirement

Send LONGWELL your airflow and pressure duty point, power supply, available installation space, control requirements, operating environment and drawings. Contact our engineering team to discuss a suitable configuration.
