PTC Thermistor Water Heater
Product Details
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of ptc thermistor water heater in China, also supports custom service. Welcome to wholesale high quality ptc thermistor water heater at competitive price from our factory.
- A PTC water heating element is an efficient heating solution that uses PTC technology, making it ideal for various water heating applications. PTC heaters are self-regulating, which limits their maximum temperature and prevents overheating. This means you don't need external temperature control devices, which makes it safer, more energy-efficient and more reliable.
- PTC water heating elements are made from ceramic and are used in water heaters, home appliances and cars. They heat up quickly, distribute heat evenly, and work well in changing conditions. This makes them ideal for modern water heating systems.
- This technology extends the lifespan of the heating element and reduces energy consumption. PTC water heating elements are popular for both domestic and industrial use.
Specifications of PTC Thermistor Water Heater
1. Operating Voltage (V)
The voltage at which the PTC heating element works. Common values are 12V, 24V, 110V, 220V, or customised.
2. Power Rating (W)
The power output of the PTC element in watts, typically from a few to several hundred. The power output can change with temperature.
3. Temperature Range (°C)
The temperature range of the heating element. PTC elements maintain a consistent temperature, typically between 80°C and 260°C.
4. Maximum surface temperature during operation
It depends on the PTC material's Curie temperature, above which the resistance increases, preventing further heating.
5. Curie Temperature (°C)
The temperature at which the PTC material's resistance increases rapidly, limiting the heating process. This temperature is often set between 80°C and 150°C for water heating.
6. Resistance (Ω)
The initial resistance of the PTC element at room temperature. As the temperature rises, the resistance increases, regulating the current flow and heat generation.
7. Dimensions
The size and shape of the heating element can be customised. Common shapes include plates, rods, and tubes.
8. Material Composition
PTC elements are made from ceramic materials that regulate temperature.
9. Waterproofing/Insulation
The element is often coated or sealed to prevent water, electrical hazards and corrosion.
1. PTC water heating elements regulate their heat output based on the temperature.
As the temperature rises, they limit the flow of current to prevent overheating. This feature means you don't need external thermostats or temperature control devices.
2. Stable Temperature Control
PTC heating elements maintain a consistent temperature once they reach their Curie point. This means the heat is always the same and there are no changes in temperature, so it is reliable.
3. Low Maintenance
PTC heating elements need little maintenance because they don't have complex external controls. They don't need checking or adjusting often, so they're very convenient for long-term use.
4. Corrosion Resistance
Many PTC heating elements are designed to resist water damage and corrosion. This makes them last longer and work well even in harsh conditions.
5. No external sensors needed
PTC elements regulate themselves, so external sensors or control systems are usually not needed. This makes the system easier to design and cheaper to make.
6.PTC elements operate silently
Making them ideal for applications where quiet operation is important, such as in household water heaters or appliances.
Application
1. Domestic Water Heaters
PTC heating elements are used in electric water heaters, providing quick and efficient heating for homes. They are safe to use in bathrooms, kitchens and hot water dispensers.
2. PTC heating elements are used in steam generators
To produce steam for industrial processes and household appliances like steam irons. They heat up quickly and keep a stable temperature.
3. Aquarium Heaters
PTC heating elements keep aquarium water at a steady temperature for fish and other aquatic life.
4. Medical equipment
PTC elements are used in medical devices that require water heating, such as sterilizers or dental equipment. They offer precise temperature control and reliable performance, which are critical for safety and efficacy in healthcare applications.
5. Home Appliance Humidifiers
In humidifiers, PTC water heating elements heat water to create steam for moisture production, ensuring consistent and safe operation without the risk of overheating.
6. Solar Water Heaters
PTC elements are also used in solar water heaters to provide extra heat when there isn't enough sunlight. They keep the water temperature stable and prevent heat loss in solar systems.
