Humidity Input
Humidity input is provided via specialist humidity injection nozzles. Water is piped through the ‘non-drip’ valve assembly which, when activated, is opened by means of the pressure of the compressed air supply allowing the water to be atomised through the ultrasonic nozzle. Once the humidity set point has been reached, the water supply is switched off a split second before the compressed air, thus any remaining water inside the nozzle is forced out and because the nozzle is effectively empty, no dripping out of the end of the nozzle occurs.

The whole humidity injection system is controlled through a main ‘control panel’ which contains the necessary solenoid valves, and timers if applicable for the humidity control.

The system comes complete with water filters, an ultra-violet water disinfection unit and, if required a magnetic water softener. All equipment is individually sized to meet the demands of the client’s products.

Humidity Distribution
The humid air is evenly distributed throughout the chamber by means of a ductwork distribution system. The nozzles are positioned directly in the air stream at the point where the supply ductwork enters the chamber thus ensuring that condensation does not occur inside the ductwork causing unwanted corrosion.

Humidity Control
The humidity within the chamber is sensed by a specialist humidity sensor positioned either directly within the chamber or in the primary air recirculation ductwork depending on the type of system being installed. This signals the PLC controller located in a ‘remote’ Control Panel to modulate the humidity input in accordance with the relevant set point programmed into the Instrument.
