Plate Heat Exchanger for Cummins Diesel Generators
Cummins KTA50G3
Generator Set, 60Hz, 1800rpm
A radiator is one of the essential components in our standard diesel generator sets, and it cools the diesel engine by air-cooling systems. Apart from cooling by a radiator, there are alternative cooling methods, for example, a heat exchanger.

In this project, we assembled a plate heat exchanger in replacement of a radiator for an open type Cummins KTA50-G3 diesel generator. The plate heat exchanger, also called heat exchanger cool, consists of a metal plate stack supported by a fixed frame. At the sides of the plate stack, there are portholes for heat transfer by water to water cooling mode. The plates in the plate stack can be added or removed to vary cooling capacity for maintaining optimal operating conditions. The plate heat exchanger has undergone pressure tests to ensure no leakage.


Both radiators and plate heat exchangers provide effective cooling effects. Due to the absence of radiator belts, however, a plate heat exchanger has lower maintenance costs. The adoption of a plate heat exchanger is suited for generator rooms with limited space and low noise requirements, as it does not require a large airflow for cooling and it generates less noise than the radiator fans do.


A plate heat exchanger applies to various model types of our diesel generators. To let us assist you to quote efficiently, you may state the following requirements:
- Are you using seawater or freshwater?
- Are you using a cooling tower or a remote radiator?
- What is your water pump pressure?
- What is your operating ambient temperature?
- What is the distance between the remote radiator and plate heat exchanger?
