S-BAR technology provides cost efficient, higher flow and lightweight radiators – custom-engineered to fit OE per formance and design requirements
S-BAR is a high strength automotive style core design, built with durable multi row tube to header plate design. S-BAR brings you the most af fordable, high flow cooling technology on the market today. Engineered for use in applications with higher temperatures and heat loads. S-BAR is a lightweight, reliable, and cost-effective aluminum solution.
With S-BAR technology, our OE-focused Application Engineers are ready to solve the most challenging system requirements for custom cooling modules.
Using S-BAR technology our engineers design mobile equipment for rigorous performance and design requirements. We can custom-engineer manifold connection requirements to suit the customers need. For higher volume applications, tooled and molded plastic top and bottom tanks can be designed.
Cores:
S-BAR is manufactured with a close-tolerance tube that has a longitudinal seam butt-welded by a high frequency (H.F.) welding process. This permanently leak-tight tube, produced in a high speed single pass operation, provides a high burst pressure. Diameters can be held within +/- .002 inches. Tubes can be manufactured from copper, brass, clad aluminum and a variety of other materials.
S-BAR cores are manufactured in a wide variety of standard and custom sizes. Standard widths of 14.87" and 18.18" are available and a range of 8 standard core lengths from 17" up to 26.25". Any custom size core design is tooled to the OE requirement. One and two row cores are available with the capacity of building multiple pass units.
Turn-Key Cooling Modules:
- Fully pressure and leak tested, to 25 – 28 PSI assembled and packaged.
- S-BAR components can be mixed and matched to provide multiple circuit cooling within one core — or multiple cores combined to form a module.
- Thermal Transfer Products can supply complete cooling packages, including in-house designed removable core guards, fan shroud, electric fan, and over flow bottle, etc.
Advantages
S-BAR provides advantages and value far beyond typical aluminum core designs.
- Superior performance
Aluminum has up to 25 percent higher heat transfer capacity in comparison to a traditional copper/brass cooling package. - Rugged structure
- Resistant to fouling
- Resistant to salt spray and salt air
- Compact
- Lower HP Application
- Domestically & LCC manufactured
- Great dollar value per BTU

Quoting & Build Process
- An application data sheet will need to be provided to Thermal Transfer Products to begin the quoting process.
To include:
OE Engine data/Hydraulic Oil data/Fan data/Application data.
Dimensional size of available envelope for cooling module.
Sketch layout to show port locations and type. - Thermal Transfer Products will provide initial predictive theoretical performance data sheet and dimensional size after required data is assembled.
- After performance data approval by customer, a budgetary quote and prototype costing will be submitted for review.
- A prototype order will trigger Thermal Transfer Products to design a top level drawing for customer signature approval.
- Approved drawing design will start the manufacturing process.
Lead times vary dependant on data discovery & complexity of cooling module. A lead time will be offered when quoted.
Look to S-BAR for cost efficient, custom-engineered units and modules for all of your OE cooling requirements.
