HUMIDITY COMPONENTS (CONTINUED)
The chamber area contains the remaining components necessary to generate and
maintain humidity levels within the work space. The following is a description of these
components (see Figures 3 to 5).
A. Solid-State Humidity Sensor
DO NOT RELOCATE. It has been located at the factory for maximum performance.
This unit utilizes a solid-state relative humidity sensor which takes the place of the
traditional wet bulb and dry bulb sensors. The solid-state sensor is a highly accurate,
quick responding, direct RH measuring device. It feeds an electronic signal to the
controller that in turn controls and displays direct relative humidity.
B. Atomizing Nozzle (Optional)
Water flows from the control solenoid at a very slow rate. Air is pumped into this
nozzle and picks up water. The chamber is humidified by the air/water mixture.
C. Humidity Wet Coil
This coil is cooled by the R-404A (System 1) system and functions as a
dehumidification coil. Dehumidification of the chamber air is accomplished by
condensing water from the chamber air onto the refrigerated surface.
D. Wet Coil Pan
The wet coil pan is used to collect moisture from the wet coil and dispense it through
the chamber drain.
E. Recirculating Water
The Recirculating Water Reservoir Option is a fully integrated accessory that requires
only minor installation. Just fill the reservoir with water to the fill line, connect a
drain line to the plastic ball valve located at the bottom rear of the unit and the
system is ready to operate.
Typical System Operation:
•
A water pump (located under the reservoir) turns on when the humidity function
is turned on and pumps water from the reservoir to the boiler.
•
The water vapor condenses into a liquid and runs down the chamber drain, back
to the reservoir.
• This cycle is repeated over and over.
• The float switch (located on top of the reservoir) turns the pump off when the
water level in the reservoir is too low and needs to be replenished, preventing
damage to the pump.
Maintenance:
• Drain and clean the reservoir every 2 months or sooner as required by usage and
water conditions.
