PTC 8KW Liquid Heater

1.Function
PTC water heating heater can provide heat for the new energy vehicle cockpit and meet the standards of safe defrosting and defogging. At the same time, it provides heat to other vehicles that require temperature adjustment (such as batteries).
2.Features
Electricity is used to heat the antifreeze, and the heater is used to heat the interior of the car. Installed in the water cooling circulation system
Warm air and temperature controllable
Use PWM to adjust the drive IGBT to adjust the power with short-term heat storage function
Whole vehicle cycle, supporting battery thermal management and environmental protection
