Liquid Cooled Sine Wave Filters | SWL Series ctmmagnetics.com

Half the size. Half the weight. Liquid Cooled. CTM Liquid Cooled Sine Wave Filters transform the output of Variable Frequency/Speed Drives (VFDs or VSDs) from a Pulse-Width

Modulated (PWM) square wave with voltage spikes and high frequency harmonics to a near perfect sinusoidal waveform. CTM’s

patented liquid cooled technology traps and removes 97% of the filter’s heat in the highest power density solution available to the

market. The largest companies in the world rely on CTM technology, with more than 200,000 installed units in some of the harshest

environments on the planet.

PRODUCT HIGHLIGHTS Motor Protection

Harmful square waves, voltage spikes, and harmonic distortion are

all filtered from the inverter output, reducing motor heating, wear,

and winding stress, providing critical motor protection.

Maximum Motor Lead Length

Reflected voltage waves occur when motor lead lengths reach or

exceed a characteristic length of the system, which is dependent

on the voltage rise times (dV/dt) in the cabling. By filtering the

PWM waveform to a near perfect sinusoidal waveform, CTM sine

wave filters minimize dV/dt, allowing for longer motor lead

lengths (up to 15,000 feet in certain applications).

Increase Motor Longevity

By reducing motor ripple current, CTM sine wave filters reduce

motor heat, noise and vibration, thereby extending motor life.

Additionally ripple current reduction eliminates torque ripple.

Filter Reliability

CTM Filters maintain lower temperatures, increasing life and

reliability. Sealed inductor designs further increase product

reliability. Due to superior heat removal technology, CTM Liquid Cooled

products are thermally isolated from their

surroundings. For further discussion, see Page 6.

LIQUID COOLED ADVANTAGES Highest Power Density

Superior heat removal technology enables smaller

magnetics, yielding the highest power density reactors

available. Low surface temperatures eliminate clearance

requirements, further increasing “effective” power density.

Thermal Isolation

With up to 97% of heat removed through the coolant,

liquid cooled reactors have negligible effects on cabinet air

temperature. No climate control required.

Sealed Design for Harsh Environments

CTM inductors are environmentally sealed in potting,

creating an extremely rugged and reliable design ideal for

use in the harshest environments.

Extremely Low Audible Noise

Due to superior materials and geometric shapes,

magnetostriction-induced noise is significantly lower in

CTM filters. When combined with a sealed package, the

result is a nearly silent solution.

CTM liquid cooled filters will have negligible temperature effects

when installed in an existing cabinet. Liquid cooled inductors are

thermally isolated from their enclosures, meaning a majority (97%)

of the heat is removed directly through the liquid coolant.

In the graphic above, both reactors are sized for a 600 HP motor

application, and are identically 99.5% efficient (0.5% power loss).

The air cooled reactor rejects 3,000 watts to the cabinet air, while

the equivalent liquid cooled reactor only rejects 90 watts to the air.

The other 2,910 watts are removed directly by the liquid coolant.

As can be seen in the graph on the right, in a typical NEMA 3R

cabinet, installation of an air cooled reactor will increase cabinet air

temperature by 20.9 °C. The equivalent liquid cooled reactor raises

cabinet air temperature by only 1.4 °C. The low temperature rise

provided by liquid cooled reactors yields increased reliability for all

electronics within the cabinet.
