PELLERIN MILNOR CORPORATION
Each tunnel module is provided with a vent at the top of the shell. These vents are capped at the
factory for shipping.
Uncap all vents at installation. The best practice is to provide two separate,
powered ventilation units that meet the following conditions:
• The two units are isolated from each other to avoid harmful chemical reactions.
• Ventilation fans have sufficient power to draw vapors away from the equipment. Milnor
recommends 600 to 750 SCFM for the oxidation zone (300 to 375 per connection point, if
two modules) and 600 to 750 SCFM for the finish zone plus the press enclosure (200 to 250
SCFM per connection point, if two modules plus the press). The SCFM values are based on
an ambient air temperature of 68°F (20°C) and a minimal relative humidity.
• Fan motors are equipped with an alarm (example: indicator light) to alert personnel if a motor
fails.
Figure 1 shows the recommended configuration for a tunnel with more than seven modules.
Smaller tunnels are similar, but consult the Milnor factory.

It is not recommended to connect modules ahead of the oxidation zone to a powered vent system.
However, if conditions warrent this, Milnor recommends the configuration shown in
Figure 2 . If
this configuration is needed, add 200 to 250 SCFM of powered ventilation per additional module
vented.
