Description:
The COP2DB is a Constant Operating Pressure Control
that incorporates a 120/1/60 Variable Frequency Drive.
It modulates the speed of an exhaust fan to maintain a
user adjustable negative pressure set point. Use only
with Tjernlund Products’ model CDB8 Booster Fan.
Pressure is measured in dryer duct at the farthest point
from the exhaust fan inlet with the included pressure
transducer and sensing tube kit. As exhaust volume
increases within the duct, the resulting reduction in
measured pressure causes the COP2DB control to
increase voltage & frequency to the fan. It speeds the
fan up to handle the additional exhaust volume and
slows it down when the exhaust volume is reduced,
modulating fan speed to maintain optimal dryer exhaust
velocity. Changes in wind, temperature and building
pressure are automatically compensated for.
