Combined Coolers & Aluminum plate-fin Heat Exchangers — Custom Oil Cooling Solutions
BAP Cooling Tec specializes in manufacturing combined cooler aluminum heat exchangers engineered for hydraulic systems, gearboxes, compressors, and heavy-duty industrial equipment. Our oil coolers deliver superior thermal efficiency in a compact, lightweight aluminum bar plate design — reducing system weight while maintaining reliable heat dissipation under continuous operation.
What Is a Aluminum plate-fin Heat Exchangers?
A Combined Coolers & Aluminum plate-fin Heat Exchangers integrates multiple cooling circuits into a single compact unit. Unlike conventional single-medium coolers that handle only one fluid type, our combined designs simultaneously cool hydraulic oil, transmission fluid, or gearbox oil alongside water or air circuits within one core. This integrated approach eliminates the need for separate cooling components, reduces installation space, simplifies piping layouts, and lowers overall system weight — critical advantages for mobile machinery where every kilogram counts.

Every unit undergoes pressure testing at 1.5× rated pressure before shipment to ensure zero-leak integrity from day one.
Applications of Combined Coolers & Aluminum plate-fin Heat Exchangers
it serves a wide range of industries:
- Hydraulic Systems: Excavators, loaders, cranes, and construction machinery requiring consistent oil temperature control under high-load duty cycles.
- Compressors: Screw compressors, reciprocating compressors, and air compression stations needing efficient oil cooling for sustained operation.
- Wind Turbine Gearboxes: Gearbox lubrication systems where reliable oil cooling prevents overheating during variable-speed operation.
- Marine & Offshore: Deck machinery, winch systems, and propulsion equipment exposed to harsh marine environments.
- Power Generation: Generator sets, diesel engines, and cogeneration systems with integrated oil-water cooling needs.
- Agricultural Machinery: Tractors, harvesters, and irrigation pumps operating in dusty, high-temperature field conditions.
