Dual Duct Type
Type: Rectangular / Round
Construction: Galvanized Steel (GI) / Stainless Steel
Application: Light & Medium Duty
Dual Duct Terminals
Dual duct terminal units are used in a special type of air distribution system where the main system has both warm air and cold air separatly ducted to each termial unit. the flow of both warm air and cool air is modulated, delivering air to the VAV zone at variable air volumes as well as variable temperatures.
A dual duct with integral mixing is similar to the non-mixing type, but has an integral mixing section between the two supply valves and the discharge duct connection. The standard mixing dual duct should provide, at a downstream distance of three equivalent diameters from the dual duct, a uniform discharge air temperature profile (±1 °F).
