Flow Meters

Flow Meters (10)

Measurement devices for monitoring coolant flow volume (LPM/GPM). Low profile, inline flow meters with steel or polymer bodies, LED lighting, and straight or 180-degree flow paths. A flow meter frequency adapter can be used to convert flow meter values to signals similar to fan RPM tachometry.


Lighting, LEDs

Lighting, LEDs (5)

UV cold cathode lights and LEDs in various colors for directed and ambient chassis illumination.


Liquid Coolant

Liquid Coolant (8)

Liquid coolants not only enable heat transfer, they must combat a variety of risks like corrosion and biological growth. Koolance liquids won't clog components and can be used for years before replacement. They also arrive in a handy squirt bottle!


Liquid Filters

Liquid Filters (2)

Inline filters screen undesirable particles or accidental debris from coolant which might otherwise affect pump operation or clog components.




Koolance magnetic centrifugal non-submersible coolant pumps range from 12 to 24 Volts DC. A spinning impeller pushes coolant through the loop.
