C.DISTRIBUTOR LOCATIONS AND MOUNTING

(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)

C.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.
