TROX Varycontrol VAV units Type TVS are volume flowrate controllers for supply air on variable volume systems.
They consist of a casing with circular inlet spigot and rectangular outlet connection, integral attenuator for the reduction of regenerated noise, damper blade and averaging differential pressure grid for monitoring the volume flowrate. The damper blade with plastic seal is air tight to DIN 1946 in the closed position.
Because the casing can be supplied in alternative lengths the unit can be selected to meet the specification requirements.
The attenuator length is short in construction and therefore the units are especially suitable for systems with less stringent acoustic requirements and limited space. The TVS unit can be supplied with two or four row reheat coils, if required.
The unit also incorporates the control components, (velocity controller, transducer. Actuator) which are factory fitted, wired and tubed. Each VAV unit is aerodynamically tested at the factory and set to the required volume flowrates.
