EMP FiC-15HV High Voltage Electric Fan

EMP’s popular 15″ electric fan has developed a high-voltage option. It has already shown great promise being integrated into several OEM cooling systems. These fans run on a voltage range of 450 – 850V and 1.5 – 3kw of power. Utilizing SmartFlow® technology, the new HV fans and components can be CAN controlled with variable speed and are diagnostics capable.

Improved Vehicle Architecture

HV components can create space in several ways, but the most notable is the elimination of DC-to-DC converters. Due to its power and heat output, a converter dedicated to the cooling system in-turn needs its own cooling system. Removing that converter not only eliminates its own weight and added wiring complexity, but it also removes the additional cooling system.

Simplified Circuits

Even wiring is simplified with HV components. HV Fans pull less current so they have thinner wiring that allows them to bundle multiple fans together onto one connector. Low-voltage components require larger wiring, in-turn requiring a separate connector for every single fan.

Brushless Motor

Brushless, permanent magnet motors are combined with EMP designed motor control electronics to provide a high efficiency, long life fan. Brushless motors have no contacting parts to wear and reduce life. Features include locked rotor protection, over temperature protection, and over current protection.

Push or Pull Configurations

EMP fans are fully reversible for debris removal and heat exchanger clean out. Fan reversal has been field proven in severe environments like forestry and stationary power generation to reduce or even eliminate the need for manual heat exchanger cleaning.

Full Speed Variable Control

Using SAE J1939-15 CAN, EMP fans can be run at any speed between the programmed minimum and maximum speed to minimize power consumption and noise. Variable speed also allows for accurate control of airflow and temperature optimization in cooling systems.

Sealed and Fully Submersible

EMP fans are sealed and fully submersible for long life operation when exposed to the elements. Fans are validated to withstand submersion and direct pressure wash. EMP fans can be submerged while running without damaging the fan. The fan will simply stop rotating and continue operation once removed from the water.
