Choose EVLINK !

Leveraging our experienced R&D team and extensive project expertise, we provide customized development and system matching services for high-voltage coolant   heaters based on specific operating conditions, delivering safer, more efficient, and more reliable high-voltage PTC liquid heating solutions to ensure optimized   thermal management performance and seamless vehicle integration.

High Voltage Coolant Heater—— K Series

2-12kW | 200V-800V | CAN | IP67

Product Features

• Excellent Water Resistance.: 

  During the actual operation, muddy roads and wet rainy days and long playing in high temperature, all require our high voltage coolant heater excellent waterproof performance.IP 67 Water and dust proof reports can be provided.
• Completely Separation of Water and Electricity: 

  Water and electricity is completely separated.Different from other manufacturers,we solve perfectly the contradiction between the heat transmission efficiency with the Insulation requirement of DC 3500 V.Benefits from this technical improvement, our 870V (nominal voltage) products have been mass produced and used in heavy dump trucks in 2021.
• PTC thermistor heater with self - controlled constant temperature.

  : PTC water coolant heater come with all advantages of the PTC heating technology. Thanks to the PTC effect, the heating elements dynamically adjust their power without exceeding a maximum temperature. High operational reliability and energy efficiency without any additional switching elements.

  Q: How does a PTC water heater work?

• A: The PTC heater works by passing electric current through PTC ceramic material. The material’s resistance increases as temperature rises, automatically adjusting the heating power to maintain a constant temperature.

• Q: Which vehicle types is it suitable for?

• A: Suitable for most electric buses, electric trucks, and electric construction machinery (excavators, loaders, etc.).

• Q: How does it perform in low-temperature environments?

• A: PTC heaters remain stable in low-temperature conditions, making them ideal for electric vehicles in cold regions.

• Q:  What are the core advantages of EVLINK PTC water heaters?

• A:High reliability, fast and uniform heating, patented thermal expansion control, moisture protection, and exceptional performance under extreme conditions.
