PTC liquid heaters for circulating-water applications.
A fluid-heating construction from our original range, including footbath and compact water-heating applications.
Match the heater to the fluid circuit
The original fluid-type design is intended for circulating-water appliances. Specify the medium, inlet temperature, flow rate and installation size so the heating assembly can be reviewed in the context of the complete circuit.
| Original catalog scope | Published range |
|---|---|
| Described footbath configuration — power | 400–1500 W |
| Described footbath configuration — voltage | 120–240 V |
| Broader family technical range — voltage | 6–240 V |
| Broader family technical range — power | 20–2000 W |
| Published surface-temperature range | 80–290°C |
The application range and broader family range describe different scopes. Not every voltage, power and temperature combination is available in one assembly. Surface temperature is not water temperature.
Information for a useful quotation
Tell us the fluid and additives, circulating flow rate or vessel volume, starting and target temperatures, available connections, heater envelope, electrical supply and duty cycle. Request a model-specific drawing and datasheet: the original page does not publish a unique model number for this family.
Fluid compatibility, leakage protection, insulation and dry-run response must be confirmed for the final appliance.
Prepare a liquid-heating inquiry ↗Immersed PTC: a separate construction.
Product-family photographs from the LC catalog. The exact construction is confirmed with your model drawing.
The catalog also lists immersed PTC heaters. Keep this range separate from the fluid-type modules above when preparing an inquiry.
| Working voltage | 6–240 V |
|---|---|
| Rated-power range | 20–800 W |
| Surface-temperature range | 100–290°C |
These are family-level catalog ranges, not all combinations in a single model. Confirm medium compatibility, insulation and the installation arrangement.
