Siemens Building Technology 186-0090 High Limit Duct Hygrostat RA 55%-95% RH

Siemens 186-0090 High Limit Duct Hygrostat is a precise device to maintain proper humidity in HVAC systems. It acts as a hygrostat mounted in a duct, necessary to control and regulate relative humidity (RH) between 55% and 95. The hygrostat monitors continuously the humidity levels in the ductwork and activates or deactivates HVAC components to maintain the set humidity range. This must be included in order to prevent the system from becoming wet or too dry and creating discomfort,possible damage to HVAC system and building material. It has ideal application in a vast spectrum of HVAC environments, ranging from commercial to industrial, which precise humidity control level is a must for process efficiency and occupant comfort.
