Liquid Heater
+What It Is
A PTC ceramic element built into a mount designed for direct or indirect contact with a liquid — water, coolant, oil or another process fluid. The mounting style (flow-through, immersion, bottom-mounted, pipe-jacket) determines how the element meets the fluid.
Product Uses
- Water heaters and dispensers
- EV / battery coolant preheating
- Industrial process fluid heating
- Beverage and appliance heating tanks
How to Customize
- Target temperature and voltage
- Wattage / heating speed
- Wetted material (for direct-contact types)
- Fitting, thread or connector spec
Air Heater
+What It Is
Stacked PTC ceramic elements with metal fins that heat moving or still air. Forced-air types pair with a fan for fast, directional output; convection types rely on natural airflow for quieter, passive heating.
Product Uses
- HVAC and cabin heating
- Defrost / defog systems
- Dryers and industrial air curtains
- Enclosure and cabinet heating
How to Customize
- Forced-air vs convection airflow
- Fin spacing and stack size
- Voltage and wattage density
- Frame / housing material
Cased Heater
+What It Is
A PTC ceramic element sealed inside a rigid housing — ceramic, plastic, aluminum, or resin-encapsulated — for direct surface-contact heating or embedding into a larger assembly. The housing material is the main engineering trade-off (isolation, cost, heat spreading, sealing).
Product Uses
- Seat and surface heaters
- Appliance heating plates
- Industrial equipment surface heating
- Small appliance heating cores
How to Customize
- Housing material
- Shape and dimensions
- Lead wire type and length
- Mounting holes / bracket points
Insulated Heater
+What It Is
A thin, flexible PTC element wrapped in an insulating film, built to conform to curved or non-flat surfaces where a rigid cased heater’s fixed geometry won’t fit.
Product Uses
- Pipe and tube heating wraps
- Flexible seat / cushion heating
- Wearable heating panels
- Anti-freeze tubing wraps
How to Customize
- Shape, length and width
- Insulation film material
- Lead wire exit position
- Adhesive backing option
Heating Chip
+What It Is
The bare PTC ceramic chip with just a lead-wire configuration — no housing. Used when your own product’s enclosure provides mechanical protection and you only need the raw heating element to embed.
Product Uses
- Compact consumer electronics
- Small appliance heating cores
- Sensor / actuator assemblies
- OEM sub-component integration
How to Customize
- Lead wire configuration (side-edge / single-surface / dual-surface)
- Chip shape and size
- Resistance value
- Electrode coating
