TC Duct High Limit

On:
In: Building Automation Systems, Helpful Information

A duct limit control is commonly used in HVAC systems to detect air temperature inside a duct. Although, these temperature controls can also be found in grain dryers. The duct limit control functions the same in the grain dryer, but rather than sensing a building air duct temperature, the limit control senses a change in air temperature inside the dryer. When the grain blocks the air flow temperature, the duct limit control senses the temperature change shutting down the system. The operator must clear the blockage and manually reset the duct limit control to resume operation. Our duct limit control is available in two differentRead More →

In: Building Automation Systems, HVAC

Senasys TC duct limit control, or also known as firestat, is required among many states to be installed in large apartment complexes and commercial buildings. The firestat is a sensing device that shuts down airflow in the event of a critical temperature increase within an air duct. Senasys offers two different firestat options, fixed or adjustable; and multiple sensing element lengths are available (5″. 7.5″, 11″ or custom). For more information about the building code regulation and how the firestat functions, continue reading below.
