Material & Advantages

1. Full stainless steel plate stack vacuum brazed molding, high heat exchange density, excellent heat dissipation efficiency under continuous heavy braking

2. Anti-corrosion 304 stainless steel core, resistant to coolant acid corrosion and high-temperature gear oil erosion, long service life

3. Integrated cast aluminum oil/water inlet and outlet connectors, standard large-caliber pipe interface, no leakage risk after pipeline assembly

4. Compact stacked plate structure, small installation space, perfect fit original gearbox mounting bracket without modification

5. Multi-layer staggered flow channel design, uniform fluid flow, avoid local high temperature hot spots inside retarder oil circuit

6. Adapt to long-distance mountain downhill transportation, long-time continuous retarder heavy-load working conditions

Application Scenarios

• Replace blocked, leaking, heat-loss original retarder radiator marked 0501 225 382 for ZF gearbox with Intarder

• Fix vehicle faults including retarder rapid overheating, automatic retarder shutdown protection, insufficient retarder braking torque, oil boiling and pipeline oil leakage

• Complete integrated hydraulic retarder disassembly overhaul and cooling system maintenance for fleets equipped with ZF Traxon / 16S series retarder gearbox
