Retrofit Terminal
Series RA retrofit assemblies are customized retrofit valves designed to slip into existing mechanically regulated single or dual duct terminals to convert to convert to variable volume operation
Series RA retrofit assemblies are customized retrofit valves designed to slip into existing mechanically regulated single or dual duct terminals to convert to convert to variable volume operation
Units allow the conversion of existing constant volume systems to a more energy efficient, variable volume systems
RA assemblies are currently available to fit most of the competitive terminals manufactured from the 60's to 80's
The RA valves can be installed, in most applications, without disrupting existing ductwork. Units are installed by removing existing volume regulators are inserting the RA valve.
One or two valves in a single panel may be controlled by a single actuator
Control sequences for the RA-500 are available to convert mechanically regulated constant single or dual duct air terminals into pneumatic VAV single duct or dual duct
