Dolphin's Hourglass Radiators: Revolutionizing Engine Cooling

Welcome to Dolphin Radiators, where we specialize in the future of engine cooling technology. Our Hourglass Radiators are at the forefront of this revolution, designed to meet the rigorous demands of today's emission regulations and the need for thermal management in vehicles for both performance and comfort.

Key Advantages of Hourglass Radiators:

Compact and Mighty: Our Hourglass Radiators are engineered to be compact, reliable, and lightweight, offering exceptional performance without taking up unnecessary space. This makes them ideal for a range of vehicles, from commercial trucks to high-performance cars.

Advanced Design: We've taken the traditional radiator and given it an upgrade. With wider tubes that have curved edges and no spacing, our design maximizes surface contact with the fins, ensuring more efficient heat conduction than standard models.

Enhanced Durability: Our radiators are built to last, featuring a fully brazed single metal construction. This approach significantly improves fatigue properties, meaning our radiators are not only strong but also incredibly resilient under high-pressure and high-performance applications.

Efficient Heat Transfer: Efficiency is key, and our Hourglass Radiators deliver it with high specific heat exchange rates (kW/m²°C) and overall high heat exchanger effectiveness. This translates into better cooling with less energy consumption.

Economic and Eco-Friendly: Alongside their performance benefits, our radiators are designed to be economically and environmentally friendly. They require reduced manufacturing expenses and feature a design that ensures a smaller economic footprint.

Dolphin's Innovation:

We offer multi-chamber radiator tubes made from high-strength aluminum alloys, available in various sizes to suit any need. Our unique louver fins permit uninterrupted heat flow, optimizing heat transfer from coolant to air without the pressure drop associated with conventional designs.

Experience the #DolphinAdvantage

Dolphin Radiators are not just about keeping your engine cool; they're about providing a sophisticated cooling solution that's built to perform and last. Choose Dolphin's Hourglass Radiators for a cooler, more efficient, and more reliable drive.

Split Core Radiators

A split core radiator is an innovative design in the realm of automotive cooling systems. Unlike traditional radiators that require the removal of the entire unit for maintenance or repairs, a split core radiator features a detachable core section. This design allows for easier and more efficient servicing, as mechanics can access the core without the need to disassemble the entire radiator assembly.

PTO Crank Box Radiators

The Power Take-Off (PTO) Crank Box Radiator is a specialized component in certain heavy-duty vehicles and machinery that incorporates both a PTO unit and a crankshaft-driven fan for efficient cooling. This integrated design serves the dual purpose of harnessing power from the engine to operate auxiliary equipment through the PTO, while simultaneously ensuring effective temperature regulation through the radiator.
