HR1616423

Overview

The nVent Hoffman HR1616423 is an HR16 series top-mount filter fan designed for electrical enclosure cooling. It operates on a 115V power supply and provides free airflow up to 266 CFM (452 m³/hr). The unit features an IP54 ingress protection rating, ensuring resistance to dust and water jets. It utilizes terminal block connections for secure wiring and is engineered to bolt directly to the enclosure top to ensure a tight seal.

Feature Summary

• Top-mount design allows direct installation on enclosure roofs
• IP54 rated housing protects internal components from environmental contaminants
• Terminal block connection system ensures secure electrical integration

Applications

• Cooling of industrial electrical enclosures
• Thermal management in control panels
• Environmental protection for outdoor equipment housings

Procurement Notes

Verify that the replacement part matches the original HR1616423 specifications, specifically the 115V voltage requirement and IP54 rating. Confirm the mounting configuration aligns with existing enclosure top openings. Ensure terminal block compatibility with current wiring infrastructure before procurement.

Selection Notes

Select this model when top-mounted ventilation is required for 115V systems. The IP54 rating makes it suitable for environments requiring protection against dust and water. Verify that the 266 CFM airflow capacity meets the thermal dissipation needs of the specific enclosure volume and heat load.

Part Context

This component belongs to the nVent Hoffman HR16 series of environmental control products. These units are specialized for managing temperature and humidity within electrical enclosures. The HR16 series is widely used in industrial automation and infrastructure applications where reliable passive or active cooling is necessary.

Replacement Considerations

Ensure any substitute maintains the 115V input specification and IP54 protection level. Verify physical dimensions match the existing cutout to avoid modification. Check that terminal block orientation and spacing are compatible with existing wiring harnesses.
