A sheath heater is a heating element that surrounds a heating wire with an insulating material for electrical insulation, and further protects it with a metal tube on the outside. The lifespan is fundamentally a function of the wire diameter and temperature of the heating wire, but corrosion of the heater pipe can also limit its lifespan. Metals ultimately oxidize or chlorinate, leading to corrosion and forming metal oxides or metal chlorides. To minimize this change, methods such as "selecting a steel type suitable for the environment" and "applying surface treatments like pickling and electro-polishing" can be employed. **Main Factors Determining Heater Power Consumption** - Type of substance being heated - Mass of the substance being heated - Flow rate of the substance being heated - Pre-heating temperature (°C) and required post-heating temperature (°C) *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce the "Battery Heating Heater" offered by Churitsu Electric Co., Ltd. In cold regions and low-temperature environments during winter, batteries experience a significant decrease in performance, and during parking or charging, there can be a decline in charging efficiency or even a phenomenon where charging is not possible. This product is a heater that warms the battery to an appropriate temperature without compromising its inherent capabilities, even in low-temperature environments. 【Features】 ■ Effect: Prevention of charging capacity reduction ■ Components: Battery *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Transparent Film Heater" offered by Churitsu Denratsu Co., Ltd. Various devices are installed in automobiles to ensure greater safety. In particular, cameras and various sensors can be hindered by snow, freezing, and fog in cold regions, which may prevent safety devices from functioning properly. Our product is a heater in film form that maintains high transparency and can heat surfaces, effectively removing factors that obstruct external information such as snow melting, ice melting, and anti-fogging.

PTC air heaters (positive temperature coefficient heaters) are heaters that use ceramic elements with PTC (Positive Temperature Coefficient) characteristics. They are self-temperature-controlled, highly safe, and energy-efficient air heaters. PTC air heaters are high-efficiency heating devices installed in electric vehicles, providing a comfortable cabin temperature. Heaters utilizing PTC materials feature rapid heating, energy savings, and long lifespan, demonstrating stable heating performance even in winter or extreme weather conditions. Additionally, their compact integrated design makes installation easy, offering excellent space efficiency. Furthermore, they are versatile, suitable not only for vehicle heating but also for household heaters. PTC air heaters represent cutting-edge technology that contributes to environmental protection, comfort, and safety, making them an essential component supporting the spread of electric vehicles.
