The KNOX SALES COMPANY S460-BAG is a screw plug immersion heating element rated at 6000 watts and 480 volts. Screw plug elements thread directly into a tank or vessel fitting, making contact with the liquid or fluid medium to deliver resistive heat. This element is typically installed by licensed plumbers, HVAC technicians, or industrial maintenance professionals servicing water heaters, boilers, process tanks, or similar fluid-heating equipment. The 6000W output at 480V positions this unit for commercial or light industrial applications where higher voltage three-phase or single-phase 480V power distribution is present.
This screw plug element is suited for commercial water heating systems, industrial process tanks, and storage-type water heaters operating on 480V electrical supply. It threads into a standard screw plug port on the tank or vessel wall, replacing a failed or degraded element as part of routine maintenance or system repair. Applications include commercial laundries, food service equipment, hydronic systems, and industrial fluid processing where 480V service is available.
Designed as an OEM-style replacement screw plug immersion heating element for commercial and industrial water heaters, process tanks, and fluid heating vessels equipped with a standard screw plug port rated for 480V service.
Installation should be performed by a licensed electrician or qualified HVAC or plumbing technician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all electrical power to the heater or vessel before removing or installing any heating element. Ensure the tank or vessel is fully drained before removing the element to prevent burns or flooding. Verify that the replacement element wattage, voltage, and thread size match the original specification before installation.
