A PTC liquid heater is a self-regulating PTC ceramic element built into a mount designed to heat water, coolant, oil or another process fluid. Unlike a fixed-resistance heating coil, the ceramic core throttles its own power draw as it approaches its target temperature, so the heater can’t run away even under a stuck-on fault.

As a PTC liquid heater manufacturer, PTCWORKS supplies four mounting architectures. The right one depends entirely on how the heater needs to meet the fluid — whether it sits inline in a flow path, submerges directly in a tank, heats through a vessel wall without touching the liquid, or wraps around an existing pipe.
