TWI Systems Group radiators are designed using patented technology that insures your product's cooling system is durable and reliable. Our patented “Big Foot” tank seal provides a more robust tank to header seal over the conventional header to tank joints found on our competitor’s designs. Our patented “Stress Flex” side support design allows the radiator core to flex during thermal and pressure cycling without compromising the structural integrity of the radiator.

Core sizes range from a single row header design of 16mm, 26mm, 32mm, 36mm (B-tube design) thick, and a double row header design of 56mm and 68mm thick.

Radiators are offered in two types of construction:
• PTA – Plastic Tank and Aluminum Core
• Aluminum Tank and Core
• Brazed Tank
• Welded Tank

Coolant Lines
Coolant lines are manufactured in aluminum, stainless steel, and low carbon steel. Brackets and saddle tubes are added easily with our state-of-the-art brazing and welding technologies.
