Operation
October 2018 | 287849-ENG, R00 27
The ASNH controls the relative humidity inside the cabinet when the operator-selected relative
humidity setpoint is above the actual relative humidity level displayed by the control system, 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 ASNH.
Complete product specifications are available upon request.
To adjust the ASNH:
Refer to the supplied control system manual for a complete description and operating instructions.
5.10.2 Ultrasonic Humidification System (USH)
This optional additive humidification uses vibrating discs to generate soundwaves underneath the
surface of the water, forming a fine mist of vapor that is absorbed by the flow of air. The amount of
humidity depends on volume of water inside the tank, water temperature, and the distribution of
air. Ultrasonic humidifiers control relative humidity to ±3% on the set point.
To adjust the USH:
Refer to the supplied control system manual for a complete description and operating instructions.
5.10.3 Bypass Dehumidification
The Bypass Dehumidification (BDH) is an optional dehumidification system used to achieve
relative humidity set points below the resultant of ambient conditions and moisture load in the
cabinet. A precisely controlled volume of chamber air bypasses the heat exchanger by means of a
proportionally controlled air damper. Using excess capacity in the cooling system, moisture is
removed from the remaining air by cooling and reheating.
To adjust the BDH:
Refer to the supplied control system manual for a complete description and operating instructions.
