Diesel Radiator Supplier For Cummins, CAT, Perkins, MTU | VRCOOLER Genset Replacement Radiators
For global fleet owners, power‑plant contractors and critical‑facility operators, sourcing reliable aftermarket diesel radiators for well‑known engine brands such as Cummins, CAT, Perkins and MTU is essential to keep standby and prime‑power generator sets running without unplanned overheating shutdowns. As an experienced diesel radiator supplier, VRCOOLER delivers drop‑in replacement radiator cores and complete radiator assemblies (with fan, shroud and charge‑air cooler options) compatible with these mainstream diesel genset engines.
We manufacture both copper‑brass and fully‑brazed all‑aluminum radiator solutions. Copper‑brass radiators are preferred for hospital, data‑center and mission‑critical standby gensets due to good anti‑corrosion performance under long idle‑standby periods and convenient field repair capability. All‑aluminum radiators provide lightweight and cost‑effective options for general industrial and mobile power projects. Combined water radiator plus air charge cooler (CAC) integrated assemblies are also available for turbo‑charged engine models.
Brand‑by‑Brand Compatibility
Cummins Genset Radiators Covers popular power generation engine series: 4BT, 6BT, 6CT, NTA855, KTA19, KTA38, KTA50, QSK19, QSK38, QSK50 and more. We build radiators for standby and prime‑power generator units from 50 kW up to 3000 kW, matching original heat‑rejection requirements, mounting hole layout and pipe interface positions.
CAT (Caterpillar) Generator Radiators Aftermarket replacement cooling assemblies for CAT 3406, 3408, 3412, C15, C18, C27, C32 generator engines. Custom built according to OEM part number, core dimension or sample reference, suitable for stationary standby power and heavy‑duty industrial gensets.
Perkins Genset Radiators Compatible with Perkins 400, 1100, 1300, 2200, 4000 series generator engines. Complete radiator assemblies with mechanical belt‑driven fan or optional DC electric fan for silent‑canopy and open‑frame generator applications.
MTU Diesel Generator Radiators Custom radiators for MTU Series 2000 and Series 4000 high‑power diesel gensets. Support standalone water radiators or combined radiator‑CAC modules for large‑scale backup‑power installations. Strict vibration‑resistant construction matches MTU's high‑load working characteristics.
VRCOOLER Key Advantages
Drop‑in aftermarket replacement No frame modification required when dimensions, mounting points and connections follow OEM specs. Provide bare radiator cores or full complete assemblies including fan, shroud, protective grille and mounting hardware.
Two material options for different working conditions ‑ Copper‑brass core: High reliability for critical standby power, humid basement and coastal environments. ‑ Brazed all‑aluminum core: Light‑weight, cost‑saving for standard industrial gensets.
Customization supported We accept custom orders based on OEM part number, old‑unit sample, technical drawing or key dimension data. Thermal calculation is performed to guarantee sufficient heat rejection for local maximum ambient temperature, high‑altitude or dusty‑site conditions.
Strict factory testing Every radiator undergoes pressure leakage test before shipment. Heat‑rejection performance test reports can be supplied for project‑file archiving. Standard 12‑month product warranty is offered.
Typical Application Scenarios
‑ Hospital & data‑center emergency backup generators
