Space-Saving VFD for Electrical Rooms and Retrofit Projects

Compact Footprint

More Performance in Less Electrical Room Space

Electrical rooms, pump stations, and mechanical spaces are often designed with limited capacity. Expanding cabinets or adding bulky external mitigation hardware is not always practical.

SmartD Clean Power VFD technology helps modernize motor systems while making better use of existing space. By reducing the need for external devices such as harmonic mitigation and output filtering equipment, it supports a cleaner layout, less panel congestion, and simpler integration into existing electrical infrastructure.

Why Space Saving Matters

Space inside electrical rooms is limited and valuable.

When a drive installation requires multiple external mitigation devices, the overall system can take more room, generate more heat, and become more complex to install.

By reducing the need for added hardware around the drive, Clean Power VFD can help facilities achieve:

Better Use of Electrical Room Space
Reducing external mitigation hardware frees valuable cabinet and floor space.

Simpler Installations
Fewer external components mean cleaner layouts, less wiring, and less mounting hardware.

Lower Heat Load
Removing added filters reduces heat dissipation in electrical rooms.

Easier Retrofits
A simpler overall installation can fit more easily into existing infrastructure.

Typical Space Challenges

In many installations, conventional VFD systems require additional mitigation equipment around the drive.

This often includes:

Input harmonic filters
dv/dt filters or sine wave filters
Output reactors
Additional cabinets or mounting space for mitigation hardware

While these solutions can be effective, they increase the total system footprint and add complexity to the installation.

The Clean Power VFD Approach

Clean Power VFD technology addresses electrical side effects directly within the drive rather than relying on external mitigation equipment.

Key design characteristics include:

Ultra-low input harmonics
Near-sinusoidal motor output
Reduced common-mode voltage
Grid-friendly design for flawless, interference-free operation.

By addressing these challenges within the drive itself, SmartD systems can eliminate the need for many external components.

The result is a simpler overall installation with less added hardware, less panel congestion, and better use of available space..

Key Benefits

By reducing the need for external mitigation equipment, Clean Power VFD can deliver several practical advantages:
- Less cabinet and panel congestion
- Simplified electrical design
- Less wiring and installation effort
- Lower heat load inside electrical rooms
- Fewer components to maintain
This helps engineers to modernize motor systems while keeping installations cleaner, simpler, and easier to manage.

Ideal Applications

This approach is particularly valuable in applications where available space is limited and adding external mitigation equipment is difficult:

Retrofit projects with limited panel space
Water and wastewater pump stations
Data center cooling infrastructure
Mechanical rooms
Industrial process skids
Agricultural pumping systems

These environments benefit from solutions that simplify the overall installation and make better use of existing space..

Real-World Retrofit Example

In many retrofit projects, electrical rooms were not designed to accommodate large external mitigation equipment.

By installing SmartD Clean Power VFDs, facilities can often remove external filters and simplify cabinet layouts while improving power quality.

This approach helps modernize existing infrastructure without expanding electrical rooms or adding complex hardware.
