Cleaner Power for Mission-Critical Cooling Infrastructure

n modern data centers, cooling infrastructure directly supports compute performance and must operate reliably, efficiently, and without interruption

Designed for Data Center
Cooling Systems

Clean Power VFD is particularly well suited for cooling infrastructure such as:

Cooling tower fans
Condenser water pumps
Chilled water pumps
CRAH and AHU supply fans
Free-cooling systems

These applications rely on stable motor performance and consistent airflow to maintain optimal server temperatures and uptime.

Built for Dense Electrical Environments

Data centers often operate with many drives on shared electrical infrastructure, including:

Multiple drives on shared feeders
Long motor cable runs to rooftops
Strict harmonic compliance requirements
High-availability architectures such as N+1 or 2N redundancy

Clean Power VFD technology is designed to operate smoothly in these environments, supporting stable power quality and predictable motor behavior across dense installations

A Simpler Electrical Architecture

Instead of relying on external mitigation equipment, Clean Power VFD improves power quality directly within the drive.

Key characteristics include:

Ultra-low input harmonics
Near-sinusoidal motor
Reduced common-mode voltage
Lower bearing stress
Cleaner shared-bus behavior

By addressing electrical disturbances at the source, Clean Power VFD can help simplify drive installations in dense cooling plants.

The Clean Power VFD Advantage

Instead of adding mitigation hardware to compensate for electrical noise, we engineer cleaner output directly within the drive topology.

What That Means in Practice

Low input harmonics across the full load range
Near-sinusoidal motor output
Reduced common-mode voltage
Lower bearing stress
Cleaner shared-bus behavior

The result is a simplified electrical architecture — particularly valuable in dense cooling plants.

EXAMPLE: Cooling Plant Retrofit

In a cooling tower installation serving critical infrastructure, the facility faced:

Long motor leads
Harmonic concerns
Limited mechanical room space
The need to protect uptime

By replacing conventional PWM drives with Clean Power VFDs:

The harmonic profile improved
Motor electrical stress was reduced
External sine filters were eliminated
Cabinet footprint was simplified

These improvements helped streamline the cooling plant architecture while maintaining system reliability.

Why This Matters in Data Centers

Reliable Redundancy

Cleaner power helps reduce nuisance trips that could affect N+1 cooling redundancy and overall uptime.

More Efficient Electrical Rooms

Reducing or eliminating external filters can lower heat generation and free valuable electrical room space.

Better Motor Protection

Near-sinusoidal motor output reduces electrical stress on motors, especially those connected through long cable runs to rooftop cooling equipment.

Simplified Harmonic Compliance

Low THDi helps simplify coordination with utility requirements and internal data center power-quality standards.

Ideal Applications

Clean Power VFD is particularly well suited for:

Hyperscale data centers
Colocation facilities
Enterprise data centers
District energy cooling loops
High-density IT environments

Especially in installations where harmonic compliance and motor reliability are critical to maintaining uptime.
