Page 23: Steam Supply Piping
Steam Supply Piping PURE recommends stainless tubing or pipe to match the steam outlet diameter connection on the humidi er cover. Stainless has superior corrosion resistance over copper and is less expensive but slightly harder to install. Stainless tubing is preferable over stainless pipe due to the fact that the tubing is less expensive and reduces heat loss/condensate formation during operation. -
Page 24: Blower Pack
Blower Pack In applications where a ducted air system is not available, PURE off ers the optional Blower Pack. The Blower Pack contains a two-speed adjustable blower that moves the air over the steam discharge outlet and disperses the steam directly into the space (see Fig. - Page 25 Blower Pack Locating Blower Pack The distance that visible steam will travel after leaving the Blower Pack is dependent upon the relative humidity in the room and the capacity of the humidifi er. If this visible steam comes in contact with any solid object (walls, beams, machinery, etc.) it may form condensate and drip.
