H2 Big Karting Radiator - AF Radiator
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.
Applications and compatibility
The H2 BIG radiator is designed for Karting engines and recommended for all categories:
-
OK
-
Kz
It is widely used and recommended in national and international competitions such as Karting Championships, Italy Cup, Italy Championship, the European Championship, the World Championship, as well as WSK, ACI and FIA events.
Seasonal recommendation
-
Summer
This model is particularly suitable for high heat conditions and very demanding cooling circuits.
Dimensions and weight
-
Dimensions: 435 × 290 × 48 mm
-
Weight: 2,25 kg
Amenities provided
The H2 Big radiator comes complete with:
-
Plastic plug
-
CNC machined aluminum supports, machined in the mass
-
Supports available in Silver, blue and red
Benefits
-
Very high performance engine cooling
-
Excellent thermal stability by strong heat
-
Water capacity greater than model H1
-
Optimized weight despite a larger volume
-
Excellent value for money
-
Suitable for high level competition
Mounting tips
To ensure optimal performance and maximum reliability, it is recommended to entrust the assembly and commissioning of the radiator to a karting professional, especially in a competitive setting.
