The ultimateSteam direct steam humidifiers are designed to receive pressurised
steam from a centralised system, treat it to remove all the condensate, and
finally distribute the dry steam directly into the duct or air handling unit.
ultimateSteam is covered by various patents, and ensures excellent performance
for use in the more critical conditions, above all where limited distance is
available for the absorption of the steam. The steam flow-rate ranges from 1
to 990 kg/h, while the dimensions vary from 300 mm to 3000 mm in both width
and height.
ultimateSteam can be supplied complete with steam valve and electronic or pneumatic
actuator, as well as a condensate drain.
ADVANTAGES
• minimum absorption distance: the outlet of steam
through continuous slits (rather than through nozzles, as in most of the
competing systems) creates a thin layer of
steam that flows uniformly from both sides of the distributor, creating
a large surface of contact with the air, allowing a minimum absorption
distance (typically
half the distance of conventional systems);
• minimum losses due to condensation: the distributors are coated
with a layer
of very high tech ceramic insulation (deriving from aerospace applications),
which reduces by up to 90% the losses due to condensate and the heating
of the
surrounding air. The lining of the distributor, 0.8 mm thick, reduces
the temperature of the outside surface to no more than 50 °C, even
when the steam inside reaches 120 °C. This insulation also allows
lower steam pressure to be used, with advantages both in economic and
safety terms;
• no emission of droplets of condensate: the vertical distributors
feature a special herringbone condensate separator, which traps and returns
any droplets of condensate back to the centre, where these evaporate again.
This is possible due to the herringbone constructional shape of the vertical
pipes;
• long periods without maintenance: all the parts of the distributor
are made from steel, without gaskets, nozzles or plastic parts that may
be affected by thermal stress.
Components
The ultimateSteam direct steam humidification system includes:
• the ultimateSteam supply manifold (top and/or bottom);
• vertical distribution manifolds;
• steam inlet filter and pipes;
• steam valve with pneumatic or electronic control;
• thermostat socket with float
Method of installation
The ultimateSteam direct steam humidification system is sized based on
the actual dimensions of the duct.
The valve and condensate drain can be fitted inside or outside the duct
(to be specified for the configuration).
