Humidity controls are designed to regulate the relative humidity
of confined spaces by cycling humidifying or dehumidifying equipment.
They are designed for use as internal components for portable humidifiers
and dehumidifiers, and as wall mounted humidity controls for central
systems.
APPLICATIONS
- Dehumidifiers.
- Space and Product Humidifiers.
- Ventilation fans for confined spaces.
- Materials processing.
- Central HVAC units

FEATURES
|
|
- Strong plastic frame with integral switch.
- Improved woven nylon sensing element provides 12 times faster
speed of response than film nylon elements.
- Greater stability of setpoints over dramatic changes in relative
humidity.
- Improved differential allowing 5%RH.
- Switch grade plastic frame eliminates the need for grounding
the control.
- Choice of 5% or 15%RH differentials.
|
- Choice of (2) SPST and (2) SPDT switches to better match applications.
- Choice of fixed or adjustable setpoints.
- Choice of dial shaft flat orientation.
- Gold-plated contacts available for microprocessor load applications.
- Available with case and cover for wall/duct mounting.
- Electronic controls available contact Ranco Marketing.
