Microprocessor control system

The humiFog control system is based on the latest, state of the art, CAREL pCO programmable
controller. This controller operates a Variable Frequency Drive to modulate water pressure and water
flow according to requirements. Control can be stand-alone using humidity and temperature sensors,
or the system can be controlled by a DDC signal. Modbus, BACnet, Echelon and TCP/IP protocol
interface is available through an RS485 serial communications port. A LAN (Local Area Network)
connection allows up to 32 controllers and terminals to be connected for sharing sensor information,
or even operating redundantly.
2.3

Atomizing nozzles

The humiFog atomizing nozzles are constructed of stainless steel and are available in two capacities:
6.2 & 8.8 lbs/hr (2.8 & 4.0 kg/hr). Working on the centrifugal/whirljet principle, they have no
obstructions in front of the orifice to drip or require adjustment. An internal 60 micron filter is used to
prevent impingement of the nozzle orifice, and a special internal valve closes the orifice to avoid
dripping and prevent any ambient contamination when the nozzle is off. The nozzles are mounted
uniformly in the distribution manifolds.
