Replacement Heat Exchanger For The Generator Cooling System
Vrcooler designs and produces a full portfolio of industrial heat exchangers exclusively for complete generator cooling systems, covering thermal power, nuclear power, gas combined-cycle, marine and backup power generators. These core heat exchange devices remove heat from generator windings, rotors, lubrication oil, seal oil and charge air, maintaining stable operating temperature, extending insulation lifespan and ensuring full-load continuous operation of all types of generators.
Full Product Line for Generator Cooling Systems
1. Hydrogen Surface Cooler (For Hydrogen-Cooled Turbo Generators)
The core heat exchanger for large 200MW–1000MW hydrogen-cooled generators. Hot circulating hydrogen transfers heat to cooling water via finned tube bundles. Explosion-proof IIC T4 versions are available for hazardous generator rooms.
Tube material: Copper, CuNi 90/10, 316L stainless steel
Strict helium leak testing to eliminate hydrogen leakage risk
2. Stator Water Cooling Unit
Special shell-and-tube heat exchanger for hollow stator winding deionized water closed circulation. Precise temperature control prevents local overheating of stator coils and insulation aging.
Anti-corrosion internal structure adapted to high-purity deionized water
1:1 OEM replacement for mainstream power generator brands
3. Generator Seal Oil Cooler (H₂ Side)
Heat exchanger for hydrogen-side sealing oil circulation, cooling high-temperature lubricating seal oil to maintain stable oil viscosity and reliable shaft hydrogen sealing. Dual-cooler standby design for uninterrupted power plant operation.
4. Charge Air Cooler / Intercooler
For diesel, natural gas, biogas and marine generator engines. Cools hot turbocharged intake air to boost power output and reduce NOx emissions. Shell-and-tube and compact plate-fin types optional.
Copper-nickel tube models for offshore & coastal vessels
5. Remote Air Cooler / Dry Cooler (Water-Saving Dry Cooling System)
Air-cooled heat exchanger without cooling towers, used for generator jacket water and lube oil closed-loop heat rejection. Ideal for water-scarce inland areas and urban low-noise power stations.
6. Lube Oil Cooler for Generator Sets
Dissipate friction heat of engine/generator bearings and gearboxes, stabilize oil temperature and avoid oil carbonization under long-hour running.
General Structure & Customizable Materials
Heat transfer tubes: Seamless copper, CuNi alloy, 304/316L stainless steel, titanium
Fins: High-density aluminum/copper anti-corrosion coated fins
Shell & water box: Carbon steel with anti-rust coating or all stainless steel
Supporting frame: Reinforced anti-vibration structure against generator long-term vibration
Sealing components: High temperature & corrosion resistant composite gaskets
