Cooling System Checklist

A.Have noise considerations been taken into account?

B.Has system piping been properly sized?

C.Has system been properly protected from freeze up and corrosion?

D.Have standby equipment heaters been specified?

E.Have all electrically driven devices been connected to load side of EPS connection points?

F.Have system drain valves and air eliminators been installed?

The system consists of the cooling medium which is generally a solution of water and ethylene glycol, a method of rejecting engine produced heat, and a means to transport cooling medium between the engine and heat rejection system. The first determination is the type of cooling system to use – radiator cooling or heat exchanger cooling.

Radiator Cooling

The first and simplest is the engine mounted radiator shown in Figure 2-8. The radiator, water circulating pump, fan and fan drive are mounted to the generator set base rails by the factory. This method of engine cooling is the most economical, but may require large ventilation vents and ducts. An added advantage of this arrangement is that the cooling air removes radiated heat from the engine, generator, and other equipment located in the emergency power system room.

The only remaining design work with the engine mounted radiator is arranging a method of providing air to the room, and exhausting it from the radiator. See “Air Systems”.

The radiator can be mounted remotely (not mounted directly at the engine). The remote/close system uses the same radiator type except it is mounted in another room or outside the building, but within close proximity to the genset. See Figure 2-9.
