Reference: RADGKH2LRG

The H2 Big Kart radiator is the brand new model developed by AF RADIATOR, designed to offer a Maximum engine cooling during the most demanding climatic conditions. It is equipped with the system Bi-flow, allowing a perfect cooling thanks to the Forced recirculation of "U" shaped liquid, combined with a Extra Light radiator mass more important and more efficient than that of the standard H1 model.

This specific design makes it possible to retain a volume of upper water inside the radiator, thus guaranteeing an excellent stability of the engine temperatures, especially during the very hot periods of the year.

Despite its increased cooling capacity, the radiator H2 BIG retains a mastered weight of only 2.25 kg, offering an excellent compromise between thermal performance and total mass of the kart

Technology and operation

The system Bi-flow Ensures optimized circulation of coolant:

  • Internal recirculation in "U" for homogeneous heat dissipation

  • Increased liquid retention for upper thermal inertia

  • Stable engine temperatures over long distances

  • Efficiency enhanced by extra light, larger than on the H1

The H2 BIG radiator is specially designed for highly solicited engines and high ambient temperatures.
