DRI-STEEM XT Series Electrode Steam Humidifier Installation, Operation, and Maintenance Manual • Page 35
Dispersion: Rapid-sorb (continued)
Steam supply connections to the Rapid-sorb header
1. Connect the steam supply interconnecting piping from the
humidifier to the Rapid-sorb. The steam supply piping requires a
minimum of 1/8"/ft (1%) pitch toward the header.
2. If multiple humidifiers are supplying one Rapid-sorb, a multiple
steam supply connector is provided.
• Typically, the multiple steam supply connector attaches to the
Rapid-sorb header supply end with hose cuff and clamps.
• Route the necessary number of steam supplies from the
humidifier steam cylinders to the steam supply connector.
• Position the steam supply connector to accept the steam
supplies while maintaining the necessary pitch.
• Make sure the hose clamps on the steam supply connector and
header are tight.
Condensate drain connections to the Rapid-sorb header
1. Piping must be minimum ¾" I.D. (DN20) and rated for 212 °F
(100 °C) minimum continuous operating temperature.
2. Condensate drain line must be piped as shown in the figures
on the previous 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
3. 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.
4. All drain lines must be installed and sized according to
governing codes.
