The Danfoss 130B1097 Cooling Fan is used to cool variable-frequency drives. VFDs are indispensable in HVAC systems because they directly influence the frequency, energy, and other aspects of the system with the help of control over the electric motor speed. For these drives to perform efficiently and also have a long life duration they need to be cooled where there are high loads or high temperatures. The main cooling fan works by blowing air over the VFD in a manner that it cools besides being hot just as is usual an indication that it is working. This serves the purpose of confining operation temperature, to minimize over-heating and overall harm. That is, by controlling the temperature the fan helps to control the conditions and there is no reason for a compromise of efficiency for the VFD.

Specifications

  • Volume: 1.17 dm3
  • Weight: 0.35lb
  • Type: Cooling Fan
Delivers controlled airflow for thermal management within a variable frequency drive assembly in HVAC systems. The Danfoss 130B1097 VFD Cooling Fan operates as a dedicated air-moving component that circulates air through the drive’s cooling pathway. During operation, the fan moves surrounding air across internal heat-producing components, supporting the transfer of accumulated thermal energy away from the drive assembly. It is used within VFD equipment where continuous internal airflow supports thermal management during normal operation.

Airflow Generation:
Transfers motion to the attached blades, causing each blade surface to sweep through the surrounding air. As the blades move, they generate aerodynamic forces that establish pressure differences across the fan and propel air along the available passage. Blade orientation and surface geometry influence the resulting flow direction and distribution, defining how air travels through the assembly.

Heat Exchange Support:
Temperature gradients across internal component surfaces drive thermal energy toward the surrounding air stream. As air encounters warmer surfaces, energy transfers from those surfaces into the moving air, increasing the air’s thermal content. Continued passage through the cooling path carries the absorbed energy away from the immediate component area, providing a mechanism for removing accumulated heat from the drive assembly.

Replacement Guidelines:
Replacement requires matching Danfoss 130B1097 VFD Cooling Fan physical configuration, electrical characteristics, mounting arrangement, airflow requirements, and equipment specifications. The replacement should also suit the existing drive assembly and designated cooling arrangement.

Common Failure Symptoms:

  • Reduced airflow through the drive assembly.
  • Increased fan operating noise.
  • Irregular fan rotation.
  • Excessive vibration.
  • Inconsistent cooling performance.
  • Unstable fan operation.
  • Increased thermal accumulation around components.
  • Irregular cooling-cycle operation.

Equipment Compatibility:
The Danfoss 130B1097 VFD Cooling Fan is intended for Integrates with variable frequency drive equipment requiring the corresponding cooling-fan configuration. Verify the equipment model, fan arrangement, electrical requirements, mounting configuration, and manufacturer’s documentation before purchasing.

Product Questions (11)
Customer Questions
What maintenance is typically required for cooling fans, and how often should it be performed?

Routine maintenance includes cleaning and inspection, typically recommended every few months to ensure optimal performance.

Are cooling fans noisy, and how can I ensure a quiet operation?

Many modern cooling fans are designed for quiet operation, but selecting a model with a noise rating that meets your preferences is advisable.

Can cooling fans be used in both residential and commercial HVAC systems?

Yes, cooling fans are available in various sizes and specifications to suit both residential and commercial HVAC setups.

What is Danfoss VFD?

A Danfoss VFD (Variable Frequency Drive) is an electrical device used in various industrial and HVAC applications to control the speed and power consumption of electric motors. It's designed to regulate the frequency and voltage supplied to the motor, allowing precise control over the motor's speed and, subsequently, the equipment it drives. 

What maintenance is required for the Danfoss 130B1097 Fan Assembly?

Regularly inspect the fan for dust, debris, or loose mounting screws. Clean the blades and surrounding area to maintain airflow and prevent overheating. Check for unusual noise or vibration, and ensure the fan spins freely to prolong motor and system life.

What are common issues with the Danfoss 130B1097 Fan Assembly?

  • Fan not spinning or intermittent operation.
  • Excessive noise or vibration.
  • Loose or damaged blades.
  • Overheating due to restricted airflow.

What role does the 130B1097 play in VFD thermal management?

The 130B1097 provides the air-moving function needed to circulate air through the drive’s internal cooling arrangement.

How does blade surface shape influence the movement of air?

The blade surface profile influences how air is displaced, helping establish the intended airflow direction and distribution.

Why is continuous blade rotation important during drive operation?

Steady mechanical rotation keeps the blade assembly moving and maintains airflow through the designated ventilation pathway.

How does airflow help transport thermal energy away from components?

Moving air absorbs thermal energy from warmer component surfaces and transports that energy along the cooling pathway.

What happens to air as the fan blades rotate through the cooling passage?

The rotating blades create aerodynamic forces that establish a pressure difference and move air through the designated cooling passage.

Installation Steps

Step1: Turn off power to the equipment and lock out the circuit.

Step2: Remove the old fan assembly by disconnecting wiring and mounting screws.

Step3: Position the new fan assembly in place, aligning mounting holes.

Step4: Secure with screws without over‑tightening.

Step5: Reconnect wiring per the fan’s wiring diagram.

Step6: Restore power and test fan operation.

Step7: Follow all safety precautions and ensure protective guards are in place.
