Building a new water cooling system can be quite an adventure. All the new parts fresh from the factory. Connecting everything together. The one thing builds sometimes forget is the amount of film and residue left for the manufacturing process. This full new system kit takes all that away ensuring a solid loop that will need very little maintenance. All of these residuals can create havoc in a new loop and possibly require some early maintenance.

Use the rad clean to make sure any bits and residue is flushed out of your radiator while essentially scrubbing the inside of any chemicals or film.

Next the Sys Prep is used to clean the entire loop of any dust or other debris in the tubing blocks and other components ensuring a super fresh start.

Finally use the unique PrimoPrep to get your loop prepped for possible PH imbalances caused mostly by high levels of copper mostly from large capacity radiators. With this treatment it also prepares the system for use of coolants in a mix metal closed loop environment leaving the guesswork a thing of the past.

Prep kit

Worked great vue fluid looks great after using prep kit. long process but simple, definitely worth using prep kit

Ideal for new systems

Cleans the radiator. Flushes the system of any manufacturing residue, or any leftover accumulation from use. I've used it twice now on the same system; first when I built it, a year later when I added an EVGA Hydro Copper GPU to the loop. That should cover things for a year or two. Next up will be the Existing System Kit. Thank you PrimoChill!

As for shipping, FedEx actually delivered on time, but their tracking was wrong and showed it returned to the local hub and I didn't know it actually delivered until I went to pick up the GPU. But, that's on FedEx. PrimoChill shipped promptly.

Would not build a system without this prep kit

Arrived in a reasonable time. I strained the radiators in coffee filters to see if there were any particulates left over from manufacturing. After 3 flushes, I realized that this is a very much needed pre-loop treatment. There were metal and paint flakes the size of a small grain of sand in the ExoSlim radiators I wouldn't want damaging any Nickel Plating over time. 10/10 would not build a loop without this cleaning system.
