Enhanced Vehicle Design
One of the most significant ways that HV components improves architecture is by eliminating the need for a DC-to-DC converter. The power and heat output from these converters requires their own thermal management. By removing the converter not only do you remove its weight and wiring complexity, but also the additional cooling therefore improving vehicle weight and efficiency.
Streamlined Circuits
HV fans draw less current, allowing for lower gauge wiring that enables multiple fans to be bundled together onto a single connector. In contrast, low-voltage components need thicker wiring, which requires a separate connector for each individual fan.
Brushless Motor
Brushless, permanent magnet motors are coupled with EMP designed motor control electronics to create a high efficiency, long lasting fan. These motors are free of contacting parts that can wear out and shorten their lifespan. Key features include rotor protection, over temperature and over current protection.
Switchable
The reversibility of EMP fans allow for debris removal and heat exchanger cleaning. This feature has been proven in severe environments like off high way and refuse collection where it reduces or even eliminates the need for manual heat exchanger cleaning.
Adjustable Speed
Using SAE J1939-15 CAN, EMP fans can be adjusted to run at any speed between the programmed minimum and maximum, allowing for minimized power consumption. Running the fans at low speeds also means the acoustics can be well managed whilst providing accurate airflow and managing tight temperature ranges.
Sealed and Fully Submersible
EMP fans are sealed and capable of withstanding submersion and direct pressure washing, ensuring long-term durability in outdoor environments. When the fans are submerged, they stop operation and will resume normal operation when removed from water.
