DRI-STEEM GTS Humidifier Installation, Operation, and Maintenance Manual • Page 39

Installation

• See the following pages for detailed drawings and notes for

installing single tube and multiple tube dispersion assemblies.

• See the hose kit sizing table on this page for single tube

applications.

Dispersion tube mounting

• Orient dispersion tube(s) so that tubelets (steam orifices)

point up.

• See the table on the next page for dispersion tube pitch

requirements.

• When mounting the humidifier above the level of the dispersion

tube(s), see the drip tee installation drawing on Page 38.

Condensate drain piping

• Minimum diameter (ID) for draining from one or two dispersion

tubes: ¾" (DN20)

• Minimum diameter (ID) for draining from three or more

dispersion tubes: 1" (DN25)

• Condensate drain piping must be rated for 212 °F (100 °C)

continuous operating temperature.

• Condensate drain line must be piped as shown in the figures

on the following pages. Provide a 6" (152 mm) drop prior to a

5" (127 mm) water seal to:

− Ensure drainage of condensate from the header

− Keep steam from blowing out of the drain line

• After the water seal, run the drain line to an open drain with a 1"

(25 mm) vertical air gap. Cut the drain line at a 45° angle on the

end above the drain to permit a direct stream of water into the

drain pipe while maintaining a 1" (25 mm) air gap. Locate air gap

only in spaces with adequate temperature and air movement to

absorb flash steam, or condensing on nearby surfaces may occur.

• All drain lines must be installed and sized according to governing

codes.

Table 39-1:

Hose kit sizing by capacity

Maximum

tube capacity

Hose kit

(vapor hose, dispersion tube,

and hardware)

lbs/hr kg/h

28.4 13 1½" (DN40) without drain

56.8 25.8

1½" (DN40) with drain

2" (DN50) without drain

85.2 38.6 2" (DN50) with drain

> 85.2 >38.6

These models require multiple

tube assemblies and cannot use

a single hose kit.

Notes:

• Assemble multiple dispersion tubes or use a

Rapid-sorb or Ultra-sorb dispersion assembly where

necessary to accommodate maximum humidiﬁer load.

• The smallest GTS humidiﬁer steam outlet is 2"

(DN50). Install an adaptor manifold if using multiple

1½" (DN40) dispersion tubes.

C A U T I O N !

Failure to follow the recommendations in

this section can result in excessive back

pressures on the humidifier. This will result

in unacceptable humidification system

performance such as leaking gaskets, blown

water seals, erratic water level control, and

spitting condensate from the dispersion

tube(s).
