Unified Cooler Air Flow
The unified cooler has a fan mounted on top to circulate air through the cooler and
regulate the temperature of the water circulating through it.
Table 4-15
describes the
air flow of the unified cooler at different power levels.
Noise Levels
Table 4-16
provides the measured noise levels of the HP Scitex FB10000 Industrial
Press.
Note
The noise level drops after startup is complete (approximately 2 minutes).
Tip
Installing the vacuum pump and UV extractor fan in a different room from the FB10000 can
lower the noise levels in the production area significantly.
