Frequently asked questions
Can I mix different brands of concentrate coolants?
You should avoid mixing concentrates from different manufacturers. Each brand uses unique chemical formulations for corrosion inhibitors and biocides. Combining them can cause precipitation or reduced protection. Stick to one brand, such as EK or Mayhems, to maintain loop safety and clarity. The listed options are all clear concentrates designed for specific mixing protocols.
What is the difference between concentrate and premix coolant?
Concentrate requires you to mix it with distilled water before filling your loop. This gives you control over the final color and volume. Premix coolant comes ready to use in the bottle. The EK CryoFuel Premix 2-Pack offers immediate convenience, while the concentrate options allow for custom color blending.
Which concentrate is best for eco-conscious builders?
The Mayhems X1 Concentrate is designed for eco-conscious users. It features biodegradable ingredients while still providing component protection. This 250ml option suits builders who value sustainability. It shares the same clear color and concentrate type as other options but focuses on environmental impact without sacrificing thermal performance.
Do I need a flush kit when changing coolants?
Yes, using a flush kit is recommended when changing fluids. The EK CryoFuel Clear 200ml Concentrate and Flush Kit includes cleaning concentrate to remove old fluid. This ensures your loop is clean before adding new coolant. It fits users who want a thorough flush before refilling with clear coolant.
How much concentrate do I need for a small loop?
Small loops often require less than 100ml of total fluid. The EK EK-CryoFuel Clear Concentrate 100ml bottle is suitable for these builds. It provides a non-toxic base with low conductivity. You can mix small batches to avoid waste. This volume is ideal for precise color control in compact custom loops.
Is Mayhems XT1 suitable for acrylic loops?
Yes, Mayhems XT1 Concentrate is compatible with standard loop plastics and rubbers, including acrylic. It offers reliable thermal performance and protection for your components. The 250ml size allows you to mix larger volumes if needed. It is a solid pick for builders who prefer to mix their own clear coolant.
What volume options are available for EK concentrate?
EK offers concentrate in 100ml bottles and 2-packs totaling 200ml. The 100ml option suits small builds, while the 2-pack provides more fluid for larger loops. Both maintain the same clear color and chemistry. You can also find combo kits with flush solutions for maintenance.
