(2) Ensure the total capacity of the humidifier is not higher than the allowable maximum
steam capacity of the following distributors:
(a) ASD: 25 lbs/hr (9 kg/hr)
(b) BSD: 35 lbs/hr (13 kg/hr)
(c) CSD: 115 lbs/hr (45 kg/hr)

DISTRIBUTOR LOCATIONS AND MOUNTING
(1) NORTEC distributors can be mounted in air handlers, supply air ducts or return air
ducts. Return air ducts should only be considered if all of the return air enters the
building again and is not exhausted by the air handling device. Distributors should be
mounted center or low within the duct or plenum. (See Figure 11.) Laminar airflow is
best. Down stream obstruction must be considered. The non-absorbed steam may
affect devices like smoke detectors down stream. Total steam absorption must be
accomplished before filters and silencers.
(2) Distributors come complete with a mounting plate. (See Figure 12.) Most ducts and
plenums are rigid enough to support the distributor.
(3) Longer distributors (more than 36") and distributors mounted on lighter gage sheet
metal which cannot support the distributor level in the duct will need to be supported on
the end. (See Figure 10.)
D.
MULTIPLE DISTRIBUTOR APPLICATIONS
(1) The use of multiple steam distributors can reduce the absorption distance in most
situations. Distributors can be manifolded together to create a grid to achieve shorter
absorption distances. (Consult agent and/or see Nomogram Figure 13.
