The work required to convert these installed
constant volume terminal units is very easy to perform. To retrofit, simply
substitute Design 75 VAV regulator(s) for the existing constant volume
regulator(s). The entire conversion can be completed quickly and economically,
using the existing systems and the existing ductwork.
Design 75 VAV retrofit regulators are designed
for this application. They are furnished complete with a factory supplied
and installed pneumatic actuator, plus an adaptor stool or adaptor plate
Once the retrofit regulator is installed,
the pneumatic connection from the regulator actuator is simply spliced
into the existing thermostat control line. As VAV and constant volume
units can be intermixed on the same system, all units need not be completed
at the same time. A progressive retrofit program might better suit budgetary
limits or other jobsite restraints.
Since the Design 75 VAV retrofit regulator
is installed inside the existing terminal unit, expensive modifications
to the existing ductwork are eliminated. All retrofit regulators are factory
calibrated for maximum and minimum air volume settings, eliminating costly
As illustrated, replacing a constant volume
regulator with a Design 75 VAV regulator is easy to accomplish. The volume
regulator is held in place with 2 or 4 hex nuts (depending on regulator
