HVCH QA01 Series: The Apex of DC High Voltage Liquid Coolant Heater for Large-Scale Vehicles

1. The heater is energy-efficient, providing cost savings by minimizing energy consumption during water heating processes.
2. It is equipped with built-in safety features, such as overheating protection and dry-run protection, to ensure safe operation and prevent damage.
3. The PTC Water Heater is compatible with different water sources, including tap water, well water, and recirculating systems.

In the harsh cold of winter, maintaining a warm and steady interior atmosphere in large commercial vehicles can be a daunting task. Enter the HVCH QA01 Series — a specially designed interior heater engineered to tackle this challenge head-on. Specifically developed for large-scale vehicles, this unit not only facilitates water circuit heating but also enables seamless performance regulation, promising reliable and potent heating solutions at all times.

Specification:

Applications:

• Enhanced Water Resistance: Capable of navigating muddy routes, withstanding heavy rains, or operating in high-temperature conditions, our high-voltage coolant heater proves to be resilient. Verification through IP 67 water and dustproof reports is available.
• Flexible Performance: The unit expertly controls water outlet temperature while also setting limits on maximum heat output or power usage. Its exceptional quality has earned it installations in thousands of vehicles over three years, garnering consistent praise from clients.
• Dual Defense System: Equipped with a two-tier protection system that incorporates both mechanical and electronic elements, acting promptly to shut down during short circuits, overloads, or high-temperature situations. High-voltage relays and current fuses have been included in the electrical circuit to enhance safety measures.
• Holistic Insulation: A groundbreaking design that achieves a complete segregation between water and electrical components, resolving the conflict between heat transfer efficiency and DC 3500 V insulation needs. This innovative approach facilitated the mass production and utilization of our 870V nominal voltage products in heavy dump trucks since 2021.
• Revolutionary PTC Technology: Incorporating the merits of PTC heating technology, where heating elements autonomously modulate their power intake, never crossing a pre-defined maximum temperature limit. This promises elevated operational dependability and energy efficiency without the need for additional switching elements.

Applications:

In the face of freezing mornings or biting winter nights, large vehicles such as buses and trucks require adept heating systems. The HVCH QA01 Series, with its substantial power output, stands as the optimal solution. It has found extensive usage across various large vehicle sectors, notably in the northeastern and northwestern regions of China. The system’s power, ranging from 15 to 25kW, accommodates heating, defrosting, battery warming, and other vehicular necessities. Users have the option to modify power as per their requirements, and customization options for specifications like voltage and power are available.
