L-Shaped Triple-Tube

These heaters – the 3LP, 3LS, 3LF, and 3LT series – are built in an L shape to heat the bottom of a tank, with three side-by-side elements. The standard wiring is three-phase, but single-phase is available. They have a watt density of 35 W/in².

Select a heater below by wattage and sheath material to go to an ordering page, where you can choose voltage and other options. If you don't know what sheath material you need, you can use our Sheath Material Selector.
