At what temperature would you activate Pneumatic manifold heaters?

Explanation:
Pneumatic manifold heaters are used to prevent moisture in compressed air from freezing inside lines and valves when temperatures drop. Ice can form once the air temperature hits the freezing point, around 32°F, which can block flow and impede operation. Activating the heaters at 32°F or below keeps the air above freezing, preventing ice buildup while avoiding unnecessary heating when it’s warmer than freezing. Options like 40°F or 50°F wouldn’t address freezing risk, and 20°F would trigger heating earlier than needed according to the standard practice, so the 32°F or below threshold is the appropriate trigger.
