These industrial screw plug immersion heaters are engineered for efficient, reliable heating of oils and similar fluids in tanks, reservoirs, and process systems. Each unit features a rugged 2" NPT steel fitting with (2) steel heating elements, delivering consistent performance in demanding applications.

Available across multiple voltage and wattage options, these immersion heaters are ideal for both maintaining temperature and rapid heat-up in a wide range of systems. The compact screw plug design allows easy installation and replacement, while the durable steel sheath provides long service life in compatible fluids.

• 2" NPT steel screw plug for secure, leak-resistant mounting
• (2) steel elements with optimized watt density options for process flexibility
• Designed for horizontal or vertical installation in tanks and reservoirs
• Consistent, even heat transfer for improved process control
• Engineered for use in industrial and commercial heating applications
• Most configurations usually ship in 8–10 days; select models in 10–15 days

These heaters are suitable for use with:

• Light weight oil
• Medium weight oil (select low watt density models)
• WVO (waste vegetable oil)
• Hydraulic oil
• Heat transfer oils

Multiple watt density selections help match the heater to the fluid type, minimizing coking, extending element life, and improving overall system efficiency. Lower watt density options are recommended for heavier or more heat-sensitive oils, while higher watt density models support faster heat-up in compatible light oils.
