Heat exchangers are very essential devices for the industrial applications such as power plant industries, refrigeration and air conditioning systems, and automobiles systems etc. One of the sources to produce electric power is diesel engine with generator called diesel generator. Diesel is a working fluid in this system. In general diesel generators are equipped with radiators or cooling tower systems for cooling the system. For low capacity diesel generators such as ranging from 10 to 500 kW, radiator systems are used for cooling; and for high capacity diesel generators ranging from 500 kW to 2 MW, cooling tower systems are used for cooling the system. Incorporating the cooling tower system for high capacity diesel generator to cool the system gives so many problems such as air locking, fan belt failure, water pump failure due to many auxiliaries, in addition to that pressure drop, huge quantity of water requirement and scale formation on heat transfer tube etc. due to secondary circuit. In this paper, cooling tower system is replaced by coil cooler system for 1 MW diesel generator, and observed the characteristics of diesel engine with coil cooler system. Good results were obtained compared to the existing system such as effective heat transfer rates, high efficiency, low pressure drop, minimizing the raw water requirement, power saving, maintenance and trouble free etc.

Keywords: Diesel engine, heat exchangers, cooling tower system,
