Cartridge Heater / Immersion Heater / Tubular Heater 12V Heating Element A compact 12V cartridge heater designed for direct immersion heating in liquids and small vessels. Constructed from SUS304 stainless steel, this tubular heater provides reliable, power heating for 12V applications where space is limited and rapid heat transfer is required. Key benefits Direct immersion heating for fast, efficient heat transfer to liquids and fuels. Durable SUS304 tube for corrosion resistance and long service life in wet environments. Simple mechanical installation with M16 thread and 300mm lead wires for flexible placement. Available wattages (100W, 150W, 200W) to match different heating loads while operating at 12V. Compact 100mm tube length fits into small tanks, reservoirs, and tight mounting spaces. Technical specifications Product names: cartridge heater, immersion heater, tubular heater, 12V heating element Voltage: 12V DC Wattage options: 100W, 150W, 200W Size: 12V 150W option available Tube material: SUS304 stainless steel Tube length: 100mm Wire length: 300mm Thread: M16 Package: 1PC x cartridge heater Installation caution: international power tolerance is 10% to +5% Performance notes Designed for 12V systems. Select the wattage that matches your available power and heating needs. Estimated current draw examples: 100W at 12V about 8.3A, 150W about 12.5A, 200W about 16.7A. Use an appropriate 12V power source and wiring rated for the current. Respect the stated power tolerance of 10% to +5% when planning installation and power supply. Typical applications and use scenarios Engine coolant preheating in cold climates: install into a coolant loop or reservoir to reduce coldstart wear and improve warmup times in 12V vehicle systems. Fuel or oil heating in small tanks: maintain pumpable viscosity for fuel or lubricants in remote equipment or seasonal storage. Small industrial or laboratory vessels: provide controlled immersion heating for test baths, heating jackets, or fluid temperature maintenance in 12V setups. Installation and practical tips Use the M16 thread for secure mounting and ensure proper sealing for liquid applications. Route the 300mm lead wires safely and secure connections to prevent strain on terminals. Avoid dry running; the heater is intended for immersion in compatible fluids. Verify power supply capability and wiring gauge based on chosen wattage and current draw. This 12V cartridge heater offers a compact, robust heating solution for immersion applications where reliable DC heating and corrosionresistant construction are required.
