Product Features

Efficient Airflow

Rosenberg developed DKHR450-4SW.138.5HA in an AC axial fan configuration applicable to air-handling, HVAC and refrigeration assembly, where controlled air movement contributes to assembly availability.

The stated 450 mm size enables early mechanical-envelope and mounting checks.

Its axial-flow arrangement carries a relatively large air volume along the motor axis, making it suitable for low-to-moderate application resistance.

The fan can support dependable duty when its duty point is checked against the complete application curve and thermal load. Validate sound and temperature in the finished enclosure. Keep the model reference unchanged in replacement documentation. Check environmental limits in the original product data.

Application Industry

HVAC Systems

OEM designs for HVAC and ventilation systems use DKHR450-4SW.138.5HA where a AC axial fan must provides supply or exhaust moving air. Maintaining clear inlet and outlet space helps the production system realize the expected forced-air cooling benefit.

Refrigeration

As part of refrigeration and condenser assembly, Rosenberg DKHR450-4SW.138.5HA performs a defined cooling task and moves air across refrigeration coils. Project engineers should verify mounting, ventilation flow direction and assembly resistance to preserve the intended application value.

Heat Exchangers

The Rosenberg AC axial fan DKHR450-4SW.138.5HA addresses thermal demand in heat exchangers by helping to moves air across transfer surfaces. The surrounding enclosure, filters and heat exchangers can add resistance that must be considered during selection.

Heat Pump Systems

As part of heat-pump systems, Rosenberg DKHR450-4SW.138.5HA performs a defined heat removal task and moves air through exchange sections. Assembly-level validation helps prevent a mechanically similar model from being substituted without compatibility checks.

Frequently Asked Questions

How should I select between DKHR450-4SW.138.5HA and a nearby model?

Compare the full model suffix, voltage, size, motor or controller type, mounting, airflow, pressure, power, speed, and protection; do not copy data from a similar model.

What equipment is DKHR450-4SW.138.5HA suited to?

The supplied application data covers data-communications equipment, heat pumps, ventilation systems. Confirm the installation's airflow, pressure, space, and electrical requirements.

Can DKHR450-4SW.138.5HA help reduce operating cost?

No quantified cost-saving claim is supplied for this exact item. Compare energy use, controls, service needs, and purchase cost using the required duty point.

What type of fan or control product is DKHR450-4SW.138.5HA?

The product is classified as a axial fan. Use the full model code because nearby variants can differ in motor, mounting, and controls.

What rated voltage is listed for DKHR450-4SW.138.5HA?

The upload row lists 400 VAC. Confirm phase, frequency, terminals, and local supply conditions before wiring.

What should I check if DKHR450-4SW.138.5HA develops a cooling fault?

Check supply voltage, controller signals, blocked airflow, contamination, abnormal noise, rotation, and the equipment operating point before replacing the unit.
