Inelco Hunter announces availability of the RadiFlow 630 from ebm-papst
Inelco Hunter has announced the availability of the RadiFlow 630 from ebm-papst, featuring high airflow capacity from a 630mm diameter fan. The RadiFlow 630 has a compact design, providing greater efficiency and power density for HVAC and data centre applications.
Modern HVAC technology faces rising energy costs, limited installation space and increasing performance requirements. The RadiFlow 630 provides a fan solution that addresses these challenges. High airflow rates, significantly improved efficiency in the application, and an exceptionally compact design open up new possibilities for manufacturers of HVAC units, computer room air handler units (CRAH) and fan wall units (FWU) – especially in data centres.
The RadiFlow 630 was specifically developed for applications with low to medium back pressure. Thanks to the axial flow, high airflow rates can be achieved even in narrow air ducts – without the performance losses typically associated with these designs. At the heart of the concept is a newly-developed impeller made of glass-fibre-reinforced composite material. The diagonal impeller has six blades, significantly reducing flow losses.
The efficient EC motor is integrated into the impeller in a space-saving design, significantly reducing the fan’s overall length. A specially designed motor suspension distributes forces evenly across multiple mounting points and ensures smooth, quiet operation. The integrated resonance detection feature protects the bearings during startup and enhances operational reliability.
RadiFlow 630 fans support demand-based speed control via 0–10 VDC or MODBUS RTU and are designed for continuous operation in HVAC and data centre applications. Variants with Active PFC (Power Factor Correction) reduce grid disturbances and minimise the need for external filters and infrastructure components. In combination with integrated EMC filters, international approvals, remote monitoring functions and the compact design, scalable climate control concepts with high power density can be implemented – from space-optimised air handling units to FanGrid systems in modern data centres.
Inelco Hunter works with ebm-papst to provide a Higher-Level Assembly Service, which enables fan design customisation. Furthermore, Inelco Hunter’s engineering team can help customers define project requirements, including as-yet unformed product ideas, turning a concept into an outstanding product.
