14 Product Overview 2604697-A_EN_2211_Condair GS Outdoor_IOM
4 Product Overview
4.1 Model Overview
Condair GS outdoor steam humidiers are available in three different housing sizes ("Small" for GS
50 / GS 100 / GS 150, "Medium" for GS 200 / GS 300 and "Large" for GS 450 / GS 600), two efciency
classes (high efciency: with condensing heat exchanger (option CS), standard efciency: without
condensing heat exchanger) and maximum steam outputs ranging from 50 lb/hr up to 600 lb/hr.
The humidiers have an integrated controller that controls the humidier, and also allows the humidier
to be connected to a building automation system (via BACnet, Lonworks, Modbus), or the internet so the
humidier can be controlled and monitored remotely. In addition, up to four humidiers can be set up in
a "Main-Extension" conguration using Condair's Linkup system to satisfy large humidication needs.
Small Housing Medium Housing Large Housing
GS unit type (max. steam capacity)
GS 50 (50 lb/hr)
GS 100 (100 lb/hr)
GS 150 (150 lb/hr)
GS 200 (200 lb/hr)
GS 300 (300 lb/hr)
GS 450 (450 lb/hr)
GS 600 (600 lb/hr)
Detailed information on the unit specications can be found in Section 10 on page 60.
Fig. 3 on page 16 shows the major components of the Condair GS outdoor steam humidier. The
built-in heating system consists of one or two heater(s) that is/are controlled by an internal thermostat
(set to 60.8 °F (16 °C)) to maintain an appropriate operating temperature inside the enclosure. The heat
control is automatic and cannot be activated manually.
A mechanical freeze protection valve drains all the water from the tank, ll cup, valves, and hoses to
prevent freeze up when the temperature inside the enclosure drops below 42.8 °F (6 °C).
During warm weather, a weather-shielded exhaust fan moves air through the enclosure to maintain an
appropriate operating temperature. The exhaust fan is automatically controlled by a thermostat, and
cannot be activated manually.
The Condair GS outdoor steam humidier is also equipped with a remote fault indication board (standard,
not shown) that can be used to remotely monitor the unit.
All other features of the Condair GS outdoor steam humidier are similar to the Condair GS indoor units.
Refer to the respective Condair GS indoor humidier manuals for details.
