Table 11. Steam Line Material; Table 12. Recommended Material And Size For Steam Run; Table 13. Recommended Condensate Line At Distributor(S) - Nortec NHPC Engineer's Manual

Short run < 10 feet (3 m)
Long run > 10 feet (3 m)
NOTE: Steel, Iron and aluminum tubing or pipe must not be used for the steam distribution lines with these humidifiers.
Plastic tubing and pipe also must not be used for steam distribution lines.

NOTE: Options shown in a bold-italic font require that reducers be used at both ends. These extra large sizes are to
allow for better condensation removal in long steam runs. These sizes do not permit the use of hose couplings
to connect either humidifier or distributors.
NOTE: Insulate all copper or stainless steel steam lines with minimum one inch high temperature insulation.

Table 13. Recommended Condensate Line at Distributor(s)

Dispersion Method
1 x Steam Distributor
3 x Steam Distributor*
NOTE: When using more than one distributor, the condensate line should be trapped before it is joined together.
