Installing a Precooler (Optional)
You can add a precooler to the Carousel Plus W series dryer by ordering the
optional precooler assembly. Installation is easy.
The optional precooler requires a source of city, tower, or chiller water and a dis-
charge or return line. You can use water at temperatures up to 85°F {30°C}. But
the water flow should be at least 3 gal/min {11.4 liters/min} for W dryer models
150 - 400.
1 Stop the dryer and lockout the main power.
2 Remove the side panels.
3 Remove the knockout for the precooler housing
on the dryer.
4 Install the precooler housing. Bolt the precooler
housing in place with the hose connection to the
bottom.
5 Disconnect the hose from the bottom
of the process heater tube. Connect
the hose to the inlet of the precooler
housing.
6 Connect a piece of hose from the bot-
tom of the aftercooler housing to the
inlet of the process heater.
