Heat Exchanger Bypass

The Heat Exchanger Bypass from Darley is a versatile and essential component designed for the engine cooling systems of any pumper. This product ensures efficient cooling by redirecting the flow of cool water from the pump through the condenser coils in the heat exchanger, rather than mixing directly with the engine's anti-freeze solution. This process prevents the dilution of the anti-freeze and avoids loss through the radiator overflow pipe.

Features

• Efficient Cooling: The liquid in the cooling system circulates around the condenser coils, ensuring it is completely cooled without mixing with the anti-freeze solution.
• Prevents Anti-Freeze Loss: By bypassing the direct flow into the engine cooling system, it prevents the loss of anti-freeze solution, maintaining the system's efficiency.
• Durable Construction: The heat exchanger bypass is built to last, with robust materials that can withstand the demands of firefighting and rescue operations.
• Easy Installation: It includes a drain fitting and measures 24-3/4 inches in length, with a diameter of 2-1/2 inches, and connections of 3/8" NPT x 1/2" NPT, making it straightforward to install in various engine cooling systems.
• Lightweight: Weighing only 7 lbs, it adds minimal weight to the vehicle, ensuring it does not affect the overall performance.

Applications

This heat exchanger bypass is ideal for use in firefighting apparatus and other emergency vehicles where maintaining optimal engine temperature is crucial. It ensures that the engine remains cool during prolonged operations, enhancing the vehicle's reliability and performance.
