Customised Cooling Needs for OEM Projects

Meeting OEM Cooling Demands: One Size Doesn't Fit All

From farm equipment to off-highway machines, and HVAC to industrial & gensets, each OEM project has its performance environment, thermal load, size limitations, and compliance needs. Cooling systems are no longer off-the-shelf components; they are core to equipment reliability and lifecycle cost.

At Varun Radiators, we understand that customising heat exchangers isn’t just about changing dimensions. It’s about co-engineering solutions that solve your application-specific problems while optimising cost, durability, and manufacturability.

What OEMs Expect in a Custom Cooling Partner

When product developers approach a new platform, they seek a supplier that can:

• Translate real-world duty cycles into robust designs
• Respond quickly with prototypes and design feedback
• Offer flexibility in materials, aluminium, plastic tanks, etc.
• Deliver ISO-compliant, test-validated solutions
• Adapt to space constraints without compromising cooling performance

We don’t just meet these expectations; we’re structured to exceed them.

How We Enable Custom Cooling Solutions

1. In-House Design & Simulation
Our engineering team works closely with OEM designers to create radiator and heat exchanger layouts using 2D/3D CAD platforms. This includes structural feasibility, pressure drop prediction, and space-envelope analysis.

2. Material & Manufacturing Flexibility
Whether it’s an all-aluminium TIG-welded tank for industrial use or plastic tanks for compact tractors, our full-process control allows us to adapt to various tank types, fin geometries (including wave dimple fins for dusty environments), and core configurations.

3. Fast Prototyping & Iteration
We’ve structured our prototype division for speed, often delivering trial units within days for fitment, validation, and testing.

4. End-to-End Testing and Compliance
We run all custom radiators through brazed radiator testing and conform to ISO heat exchanger standards to ensure thermal and structural performance.

5. Volume Scalability
After pilot approval, we scale up for steady production using our integrated facility with a capacity of 500,000+ units annually, ideal for OEMs with phased rollouts.

What Customisation Involves

OEM cooling customisation isn’t just about changing size. It includes:

• Choosing the right core type and fin geometry
• Selecting between plastic tanks (for compact tractors) and TIG welded aluminium tanks (for industrial equipment)
• Optimising tube count, row depth, and header design
• Matching mounting, port locations, and packaging constraints
• Meeting ISO testing standards for durability and performance
