for complete instructions.
3.11 Additive Humidification
– Spray Nozzle Humidification (SNH Option)
The optional additive humidification uses the pressure from the water supply to atomize the water
through a small orifice in the spray nozzle. The spray nozzles are located within the air handling
system of the chamber and the water is directly injected into the air stream before it is introduced
to the chamber.
A minimum of 60 psi (4.2 bar) is required to operate spray nozzles. If this water pressure is not
available, the CPSNH option is required to achieve the required pressure.
A 1/4"
compression fitting OD ‘Quick Connect’ fitting is supplied on the chamber for connection to
the mains purified water supply.
The humidification system needs reverse osmosis filtered water.
The SNH controls the relative humidity inside the cabinet when the operator-selected relative
humidity setpoint is above the actual relative humidity level displayed by the controller, within the
following parameters:
•
A relative humidity setpoint of 0 will turn OFF humidification/dehumidification devices.
•
The highest achievable relative humidity setpoint is determined by two factors:
•
Resultant of ambient conditions moisture load within the cabinet from plant
transpiration and watering or misting.
•
Capabilities of the SNH.
Complete product specifications are available upon request.
