MB1J3AX21A

The Watlow MB1J3AX21A is a versatile and powerful 240V, 700W immersion heater designed for industrial applications. This heater, featuring a type K thermocouple and a sheath material of 116N43 SI, is engineered to provide reliable and efficient temperature control for various process fluids.

The MB1J3AX21A's immersion element is a resistance heating element, which converts electrical energy into heat. The element's resistance is 15.4 at 25 C, and it is rated for a maximum voltage of 240V and a maximum power of 700W. This heater is suitable for applications where a relatively high wattage is required to maintain the desired process temperature.

The sheath material of 116N43 SI is a type of stainless steel that offers excellent resistance to corrosion and high-temperature stability. This makes the MB1J3AX21A an ideal choice for applications involving harsh or corrosive environments, and where the heater will be subjected to prolonged exposure to high temperatures.

The heater's sheath is insulated with a ceramic material, which provides insulation and helps to maintain the safety of the operator. The immersion heater is also equipped with a type K thermocouple, which measures the temperature of the process fluid in contact with the heater. This information can be used to control the heating element, ensuring that the process fluid is maintained at the desired temperature.

The Watlow MB1J3AX21A immersion heater is designed for easy installation and maintenance. The element is welded to a threaded flange, which allows for secure attachment to the process vessel. The heater also features a drain plug, making it easy to drain the process fluid for maintenance or cleaning purposes.

In summary, the Watlow MB1J3AX21A is a robust and efficient 240V, 700W immersion heater suitable for industrial applications. Its stainless steel sheath material, 116N43 SI, offers excellent resistance to corrosion and high-temperature stability, making it an ideal choice for harsh environments. The heater's type K thermocouple provides accurate temperature measurement, ensuring optimal process control. The MB1J3AX21A's easy installation and maintenance features make it a practical and cost-effective solution for a wide range of industrial heating applications.
