4. STEAM DISTRIBUTORS (ASD, BSD, CSD)
A. STEAM DISTRIBUTORS
(1) NORTEC’s steam distributors, in use for over twenty years, are a proven design to suit
applications for the introduction of atmospheric steam.
(2) Features and benefits of steam distributors are:
(a) Expanded diameter of tube to reduce steam velocity and the potential for
condensate carryover into the duct.
(b) Positive removal of condensate.
(c) Lower mass of metal (stainless steel), which reduces ‘radiator effect and
condensate’ and results in higher efficiency of humidifier output while reducing
condensate formation.
(d) Designed specifically for atmospheric steam generation.
(e) Modular so that the exact quantity of distributors can be configured to meet
specific application requirements. This reduces system complexity and installation
costs.
B. DISTRIBUTOR CHARACTERISTICS
(1) NORTEC steam distributors are constructed of stainless steel and include in low point
condensate return to prevent the condensate from collecting in the steam distributor.
This enables entrained condensate to settle to the bottom of the steam distributor
where it is removed by the condensate return. These features allow the NORTEC
steam distributors to be installed level in the duct, thereby utilizing the full available
width of the duct. (See Figure 10.)
