MECHANICAL INSTALLATION — MOUNTED RADIATOR COOLING
Mounted Radiator Cooling System
Agenerator set with a
Mounted radiator cooling system uses a set mounted radiator and engine pusher fan to cool engine water. Air travels from the generator end of the set, across the engine, and out through the radiator. An integral discharge duct adapter flange surrounds the radiator grill.
A primary consideration for mounted radiator installations is the necessity of moving large quantities of air through the generator room.
Radiator Set Requirements
Radiator set cooling air is drawn past the rear of the set by a pusher fan that blows air through the radiator (See Figure 26 below). Locate the air inlet to the rear of the genset. Make the inlet vent opening
Locate the cooling air outlet (as close as possible) directly in front of the radiator. The outlet opening must be at least as large as the radiator area. Length and shape of the air outlet duct should offer minimum restriction to airflow.
The radiator has an air discharge duct adapter flange. Attach a canvas or sheet metal duct to the flange and the air outlet opening using screws and nuts so duct can be removed for maintenance purposes. The duct prevents circulation of heated air. Before installing the duct, remove the radiator core guard.
