Stack Plate Cooler 16 Row

The Stack Plate Cooler 16 Row by Derale is a compact, high-efficiency transmission cooler designed for tactical vehicles, law enforcement units, and off-road systems operating under extreme thermal demand. Built for operators who require reliable heat management in high-stress environments—whether running armored patrol units, towing heavy loads, or operating in desert climates—this cooler prevents transmission fluid degradation and extends component lifespan in mission-critical applications. Its stackable plate-fin design delivers superior cooling capacity in a footprint that integrates seamlessly into tight engine bays or auxiliary mounting locations common to tactical platforms.

The 16-row core construction maximizes surface area for efficient heat transfer while maintaining a lightweight profile at 2.97 lbs—critical for vehicles where weight savings directly impact fuel economy and handling. The stack plate design uses brazed aluminum construction, eliminating gasket failure points and ensuring durability under vibration and thermal cycling. With compact dimensions of 8.05 × 2.25 × 18.75 inches, this cooler fits applications requiring a shallow profile, such as underbody mounting or integrated auxiliary cooling setups common in purpose-built tactical and emergency response vehicles. The parallel flow passages optimize transmission fluid velocity and cooling efficiency across a broad operating range.

Operators upgrading to the Stack Plate Cooler 16 Row will see measurable improvements in transmission temperature stability during sustained high-performance driving, heavy towing, or extended operations in arid conditions—scenarios where stock cooling systems reach their thermal limits. This cooler is compatible with any transmission system using standard inlet/outlet fittings; verify hose routing and mounting clearance before installation. Law enforcement fleet managers and military motor pools commonly specify Derale stack plate coolers for duty vehicles because their sealed brazed construction requires minimal maintenance and resists corrosion from salt exposure and pressure washing protocols.
