The gap of the generator air duct is unqualified

If the engine room temperature exceeds 40°C (104°F), the generator must be derated per the generator derate schedule and cool outside air must be ducted directly to the generator air intake. Alternatively, custom generators can be sized to handle specific ambient conditions. . The air inlet must be capable of moving enough air through the room to provide the correct minimum CFM (cubic feet per minute) cooling for generator as specified by the generator's manufacturer. Figure 1: Electric generator air gap. What is the air gap? A simple way to define the air gap is to say that it is the air in the space between the. . The exciter air gap was measured by the original manufacturer and was 4. 0mm at the 90-degree positions (0-270 degrees). This small distance is essential for preventing damage and maintaining efficiency. It has a heat rejection value of 659 kW. .
