6 FAQs about [Generator inlet cooling air temperature requirements]

What is a good room temperature for a diesel generator?

The generator’s room temperature must be maintained at 18 to 27 degrees Celsius with 40 to 60% of relative humidity. Share This Story, Choose Your Platform! Patrick Paden is a generator specialist at Central States Diesel Generators.

What if the engine room temperature exceeds 40°C?

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.

Does a generator intake need cool air?

It is important to note that cooling air is needed for more than just the engine; the generator intake also requires cool clean air. The most effective way to do this is to provide a ventilation air source low to the ground at the rear of the package.

Does a generator need ventilation?

Large generators, configured with an air inlet positioned high on the generator, will require an additional source of ventilation air. If Ventilation Type 1 or Type 2 is not feasible, an alternative is Type 3; however, this routing configuration will require approximately 50% more airflow than Type 1.

What temperature should an engine room/enclosure be?

In all cases, engine room/enclosure design must ensure that air temperature around the engine will not exceed 50°C (122°F). Critical locations include the engine torsional damper and generator coupling. Air temperature reading should be taken no more than 6 inches away from these components.
