Duct Humidity Limiter

Multi-Function Humidity Device

HL-67N5 Series

The HL-67N5 Multi-Function Humidity Device is intended to provide input to equipment under normal operating conditions.  The HL-67N5 regulates duct humidity by overriding a system controller’s demand for humidification when humidity exceeds a user-defined setpoint.

Features and Benefits
Resources
  • TRUERH offers patented circuitry and calibration
  • Multi-functional device with several humidity control applications: high limit or proportional override, stand-alone proportional or stand-alone two-position
  • All-plastic duct probe material improves thermal performance, and complies with Underwriters Laboratories® Inc (UL) flammability ratings for plenum use; complies with Blue Angel (Germany) and TCO'95 (Sweden) environmental regulations
  • All polymer humidity sensor provides patented sensing element for accurate and reliable humidity sensing with improved resistance to chemical corrosion
  • Humidity and temperature sensors in one unit eliminate need for separate sensors, reducing installation time and cost
  • Adjustable RH standpoint enables user to define duct’s maximum allowed humidity level, reducing excess humidification equipment cycling
