Maintance and Service
Custom Cooling Solutions – We engineer radiators precisely aligned with your unique engine requirements and operational environmental conditions.
Protective Packaging – Reinforced wooden crates with moisture-proof linings are used for the radiator, preventing copper component corrosion and structural damage during transit.
Guaranteed Performance – As a genuine or OEM-equivalent part, it is certified to meet MTU's stringent quality and performance standards for the 16V4000 G81 engine.
How We Produce
Our generator radiators are engineered for maximum durability and cooling performance. Through advanced thermal simulation and a fin-tube design that increases heat transfer area by 40%, we ensure superior heat dissipation. Critical joints are vacuum-brazed and argon-arc welded to guarantee leak-proof operation, even under intense vibration and continuous use.
