Product Features:


Ø Excellent Water Resistance

In the relentless pursuit of excellence, the HVCH QB01 Series stands out with its exceptional water resistance capabilities. Whether navigating muddy roads or enduring wet rainy days and extended periods of high temperature, this heater promises impeccable waterproof performance. We take pride in its IP67 water and dust proof certification, a testament to its robust construction that can withstand the harshest environments.

Ø Stepless Regulate Performance

Equipped with an innovative stepless regulate performance feature, it offers superior control over water outlet temperature or power consumption. This dynamic adaptability has earned it the trust of numerous customers, with successful integration into thousands of vehicles over the past three years.

Ø Reliable Dual Self-Protection System

Safety is our priority. The dual protection system, comprising mechanical and electronic protective measures, ensures seamless operation even in the face of short circuits, overloads or over-temperature conditions. This is further enhanced by the inclusion of high voltage relay and current fuse in the high voltage circuit, adding another layer of safety.

Ø Complete Separation of Water and Electricity

Taking innovation a step further, we have successfully eliminated the contradiction between heat transmission efficiency and the insulation requirement of DC 3500 V. This has facilitated the mass production of our 870V (nominal voltage) products, which have been prominently featured in heavy dump trucks since 2021.

Ø PTC Thermistor Heater with Self-Controlled Constant Temperature

The integration of PTC thermistor heating technology is another feather in our cap. This feature ensures dynamic power adjustment without exceeding a certain temperature threshold, promoting high operational reliability and energy efficiency without the need for additional switching elements.
