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.

Advanced Diagnostics

Intelligent diagnostics help the user understand how the pump and the entire system is operating. The diagnostics can be communicated through SAE J1939 CAN for real time analysis, or diagnostic data can be downloaded using EMPowerConnect service tool and sent to EMP for analysis. This is especially useful for troubleshooting or system development, and dry run detection.

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.
