Modular system designed around API’s High Performance Aluminum Bar & Plate technology.

  • Coil construction configured for maximum heat transfer performance – high heat transfer efficiency per surface area volume 
  • Capable of running water / water-glycol / dielectric fluids / oils / or any aluminum-compatible fluid can be considered
  • Coil connection orientation option up or down; Victaulic, flange, tri-clamp or custom
  • Connections up, all but eliminates coil fluid volume flow back on the pumping power loss. (Minimal flow back from piping volumes dependent upon installation)

Built around industry-leading Ø910mm fans. 

  • EC & AC selection options from multiple vendors

Due to the constraints of space and because of thermal considerations in many environments, an increasing number of commercial power generation installations require the cooling equipment to be remotely located from the generator room.

The kits can be cooled by a separate secondary water source, such as a cooling tower or remote radiator, and can be offered to withstand the secondary water source up to 160 meters above the engine. This makes them ideal for cooling engines situated in the basement of tall buildings, where the radiators need to be on the roof.

Base-frame mounted remote cooling kits consist of:

  • Water-cooled charge air coolers
  • Jacket water and aftercooler heat exchangers
  • All pipework to the engine is optional
  • A fuel cooler, surge tank, remote radiator, pump, and heat exchanger can also be added, if required

Turnkey Genset Radiators

Our line of General ThermoDynamics Turnkey radiator cooling packages feature our unique high-performance cores and low horsepower fan engineered into a compact envelope. Choose from pre-engineered models or request a custom sized solution based on your specific rating and site conditions.

Turnkey Engine-Driven Radiator

Specify turnkey engine-driven radiator from API Heat Transfer for your next high horsepower (3MW+ direct drive off engine) genset installation to avoid using costly remote radiators with electric motor driven fans.

  • Reduce the complexity of your genset installation
  • Provide a turnkey genset, including radiator, to your customer
  • Lower total cost of ownership (TCO)

API Heat Transfer power converter coolers are a line of our AIRTECH® Fan-Cooled Heat Exchangers, ideally suited for the cooling of wind turbine power conversion equipment. Our conversion coolers prevent inlet temperatures from exceeding maximum recommendations to ensure safe and efficient operation.

Conversion coolers feature our brazed all-aluminum construction, resulting in a bonded unitary core for unparalleled performance and cost-effectiveness in a rugged, compact, and lightweight package. Plus, our array of internal and external fin configurations allow us to select the right combination to maximize heat transfer while minimizing pressure drop, ensuring suitability for the cooler’s operating environment.

Custom Oil Coolers

Oil cooling requirements vary widely depending on the type of equipment and duty cycle required. We’ve specially selected fin and tube options to provide the exact performance and durability the application calls for. Whether its high viscosity start up or full temperature operation, our brazed aluminum oil coolers keep it cool. We carefully select each oil cooler to be compatible with your system and each product is carefully designed to provide you the best combination of heat transfer and pressure drop.
