Designed to ensure highly efficient and moisture-free steam injection in air ducts and AHU for humidification purposes.
Manufactured as a bespoke solution to meet flow requirements and duct size/configuration with single or multiple injection tube for low absorption distances.

OPERATION 

Steam moves in the supply line passing through a strainer to remove solid particles and, if necessary, through a pressure reducing valve to reduce it to humidification pressure (generally around 1 to 2 barg). Steam then passes through a S16TSS centrifugal humidity separator which removes any remaining finer particulate matter and most moisture content. The separator special design dries the steam which is injected and also the steam which feeds the heating chamber keeping heating temperatures stable. As steam leaves the humidity separator and passes through the jacketed injection tubes it is kept at a constant temperature, preventing condensation to be carried over with the steam.

Condensate collects on the bottom of the separator and is removed from the system at saturated temperature via a FLT float and thermostatic steam trap. Condensate which forms inside the injection tube heating chamber is removed by means of one or multiple steam traps depending on the case.

An ADCATrol globe control valve equipped with a fail-safe electric or pneumatic actuator provides accurate modulation of flow and, thus, precise humidity control.

CONDENSATE DRAINAGE CONFIGURATIONS FOR MULTI-TUBE HUMIDIFIERS

Remarks: The number of injection tubes may vary. Images above are merely indicative. The size of the injection tube manifold must always be greater than the nominal size of the upstream humidity separator.

A single-tube humidifier is the most economically viable solution if a single injection tube respects the humidification load and the higher absorption distance (generally associated with single-tube humidifiers) is lower than the distance to any obstacle downstream.

If on the other hand, the available distance is insufficient to accommodate the necessary absorption distance of a singletube solution or when duct height is significant then a multi-tube humidifier should be selected. This solution will shorten the necessary absorption distance by up to 4 times as the increase in injection points will decrease flow velocity and also promote an homogenous and efficient mixing.

Let's take a look at a typical DSH steam and condensate humidification line diagram

It is necessary to ensure the quality of the steam (dryness) when it is supplied to the steam humidification system. It is also necessary to ensure proper drainage of the system. Along the steam path, it is necessary to ensure that condensate flows towards the drainage and make sure that there are no stagnant areas where it can accumulate.
