E. BLOWER PACK
(1)
Wall mounted direct steam distribution system allows for direct space/room
humidification when steam introduction into a ducted system is not feasible. The
factory assembled remote mounted blower pack includes an integral steam
distributor, 3 direct drive fans.
F. SHORT ABSORPTION MANIFOLDS
(1)
This distribution system will allow a short absorption distance to be obtained.
Refer to SAM-e Engineering Manual Form #XX-247.
G. ON / OFF CONTROLS
(1)
252-0259 – Humidistat, on/off, control or high limit, wall mounted. Standard with
internal integrated humidity sensor and digital display. Adjustment range 0-100%
relative humidity with ±3% relative humidity control. Can be calibrated in the field.
(2)
132-9203 - Air Proving Switch, on/off, duct mounted, pressure differential switch,
adjustable set point from 0.07 IWC to 12.0 IWC, good for positive, negative or
differential pressure applications, stops humidifier if duct air pressure is not
sensed. Turns humidifier off if air handler fails.
(3)
252-0273 - Humidistat, on/off, control or high limit, duct mounted. Standard with
external duct mounted humidity control. Can be calibrated in the field.
G. SSR COOLING KIT
(1)
253-0620 - This kit is used for applications where ambient temperature exceeds
95ºF (35ºC). Provides additional cooling for the Solid State Relays for exceptional
conditions.
H. KEEP WARM OPTION
(1)
150-4561 - This feature allows the water temperature in the tank to be maintained
at 160ºF (70ºC) for quick response from the unit upon a call for humidity.
I. REMOTE FAULT INDICATION PACKAGE
(1)
150-8069 - This option provides four relays to monitor the humidifier remotely.
Relays are:
(i) Steam
Production
(ii) Unit
fault
(iii) Service / Maintenance
(iv) Unit
on
All relays are BMS ready.
J. NORTEC LINKS 2 OPTION
(1)
This option provides monitoring and controlling of the humidifier from a BMS
(Building Management System) using the industries leading communication
protocols. BACnet, LonWorks, Johnson N2 or Modbus. Simply specify what
operating protocol you are using at time or order. OnLine capabilities are standard.
The OnLine service must be ordered.
