HIGH EFFICIENCY CORE
CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry leading testing methods to maximize airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology!
“B-Tube” technology – Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in a shape of a “B”. These “B-tubes” are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (better cooling efficiency) because this design is actually stronger than normal “O” shape tubes that are welded.
The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube within the same space criteria. With “B-tubes” you are able to get “dual liquid laminar flow.”
High Efficiency Multi Louvered Fin – CSF uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.
DESIGN & ENGINEERING
CSF aims to lead the cooling systems industry by introducing new technologies and manufacturing processes that allows us to be on the cutting edge of heat transfer innovation.
RADIATOR TECHNOLOGY ENGINEERING:

- Wind tunnel tested for optimal radiator core cooling efficiency
- “Racing Style” Aluminum Drain Plug
RADIATOR TECHNOLOGY MANUFACTURING:
- Brazed in CAB Furnace
- ISO 9001/9002 certification
- Military Grade (special clad) aluminum used for tubes, fins, header
- Plates, and side brackets (JIS 3003 spec minimum)
- Privately owned factories with full “In house” tool rooms
- CNC machined fittings
- “Master Class” TIG welding
ADVANCED ENDTANK DESIGNS
CSF offers two all-aluminum end-tank designs to match any style and performance need.
OE Radial Tanks – Flat and rounded end-tanks that are welded together and finished with our 1 hour Show-Stopper™ mirror polish process. For the customer who likes the sleek and smooth look, and wants to display the intricate welding associated with this design (CSF 7000 series).
Deep Drawn Tanks – The only high performance manufacture to feature this advanced radiator technology. These end-tanks are stamped to the same geometry of the application’s original plastic end-tank. These tanks feature less welding, and are generally considered the strongest tank designs in the industry. Also finished with our Show-Stopper™ mirror polish.
