Johnson Controls A19ABC-42 Immersion Control 100-240 6-24° Differential

The Johnson Controls A19ABC-42 is a Direct immersion temperature control that is used for controlling the heating in different processes. It has a temperature set point range of 100°F to 240°F to help regulate the amount of heat of the liquids. Since all of these models have an adjustable differential that ranges from six to twenty-four degrees Fahrenheit, the control is simple to use, it lets you set how much the temperature has to drop before the control switches on. This immersion control operates through the detection of the temperature of the surrounding fluid by a submersible bulb. When the liquid temperature is below the set point minus the differential, the control turns on the heating element in your compatible HVAC equipment including boilers, and electric heaters.
