In the modern era of transportation, the Automotive Coolant Heater has evolved from a luxury accessory to a critical necessity. As the world transitions toward New Energy Vehicles (NEVs), the role of efficient thermal management systems has become paramount. Unlike traditional internal combustion engines (ICE) that produce waste heat to warm the cabin, Electric Vehicles (EVs) require specialized high-voltage PTC (Positive Temperature Coefficient) heaters to manage both passenger comfort and battery performance.
As a leading China Automotive Coolant Heater Manufacturer, we understand that reliability in extreme conditions is the industry benchmark. Our systems are engineered to function at temperatures as low as -40°C, ensuring that commercial fleets, public transit buses, and private EVs remain operational and efficient regardless of the environment.
With EVs adopting 400V and 800V architectures, heaters must now handle significantly higher power inputs. Our 7KW and 20KW electric heaters are designed to meet these high-voltage requirements with integrated safety monitors.
Thermal management is no longer just about the driver. Liquid heaters are now used to maintain the "Sweet Spot" for lithium-ion batteries, extending the vehicle's range and battery lifespan in winter conditions.
Modern heaters are connected to the vehicle's Battery Management System (BMS) via CAN bus communication, allowing for precise temperature regulation and energy saving.
For heavy-duty trucks and diesel vehicles, our low-emission gas and liquid heaters provide pre-heating without idling the engine, drastically reducing carbon footprints and fuel costs.
Home to the Hebei Province New Energy Vehicle Engineering Standard Laboratory, we support cutting-edge R&D. We launched China's first magnetic water pumps and three-way high-voltage insulation monitors.
Passed German Rhine ISO/TS16949 in 2008. We implement full-process quality management with automated SMT lines and over ten assembly & testing lines for maximum consistency.
Our 35,000 sqm base produces 1.2M accelerator pedals, 300K magnetic water pumps, and 50K insulation monitors annually, ensuring supply chain stability for global OEMs.
Trusted supplier for leading brands like Yutong, Geely, BAIC, and JAC. Our international footprint covers the USA, Canada, Russia, France, and more.
Global procurement teams from automotive OEMs and aftermarket distributors look for three key factors: Safety Certification, Energy Efficiency, and Scale. As an exporter with nearly two decades of experience, we provide end-to-end support for these needs.
Focus on Electric Liquid Heaters to prevent battery crystallization and ensure passenger cabin warmth during sub-zero winters.
High-power 20KW Heaters are essential for large cabins, ensuring rapid defrosting and consistent internal temperatures for commuters.
Use of Parking Heaters (Gas/Liquid) to maintain engine readiness without the high costs of idling, leading to significant fuel savings.
Our biggest motivation is the trust of our customers. Our products are fully guaranteed for performance and safety.
