Modultra LO-1UES pump top is a compact low profile 1U DDC pump top designed to fit in the smallest of spaces. Its unique 3x entry and 3x exit port configuration allows for a great degree of flexibility in your tubing runs. And because all entry ports are on the top, this means that the LO-1UES can sit flush against a chassis wall, or tucked away in a corner of your build. Because the LO-1UES is machined from solid C360 brass, when used with any of our conductor series heatsinks, your DDC pump is actively cooled by your loop coolant. During testing we have seen upwards of a 45 degree reduction in pump temperature when using a conductor heatsink.
