EMP's "Commercial Grade" electric fan is one of several proprietary thermal management products designed to help end-users improve fuel economy, decrease emissions, improve packaging and improve heat rejection. EMP calls it commercial grade because of how it operates under extreme conditions, delivering long-life utilizing a brushless DC motor, high performance and high efficiency. Also submersible, EMP's commercial grade electric fan is the most robust and durable electric fan on the market today.

There are two main types of DC motors: brushed and brushless. A brushed motor has mechanical contact between a rotating shaft and the power source in order to make the motor operate. These contacts, or brushes, tend to wear out over time. A brushless motor has no mechanical contact and thus extremely long life.

The EMP fan was designed to minimize noise as much as possible. The actual level depends on the installation.

There are several methods. It can be controlled by the engine via CAN or PWM. It can be set as an on/off when a relay sends it power. It can control itself based on a temperature set point.

The EMP fan is the only known brushless fan that passes the tough requirements of the commercial industry and thus has extremely long life. It has variable speed control, reversibility and the highest flow for its size.

The fans draw a maximum of 25 amps.

Yes, the motor is sealed, keeping dirt, water and debris out of the motor.

Currently the fan is rated at 10,000+ hours with a target of 20,000 hours.

EMP's components utilize brushless permanent magnet motors. Brushless motors require a controller to provide commutation to the electric motor. The controller takes DC power in and converts the power to three phase switched power, resulting in rotation of the motor. The frequency of the switching will then dictate the electric motor speed. The controller is also capable of accepting some signals from external sensors to provide control points for the component response to the system needs.

The fan will operate with very little clearance. Testing shows that 3 inches is usually enough room between the fan and other components. It doesn't hurt anything to have less clearance, but there will be a performance penalty.

The fans are capable of being set to run any speed in between a predetermined minimum and maximum. They can also engage and disengage at temperatures between a predetermined minimum and maximum. Fans can be set up to reverse on a time basis that can also be adjusted.

Direction of airflow is determined by looking at the fan through the radiator. A puller fan is positioned on the back, or engine side, of the radiator so that it pulls the air through the radiator core. A pusher is positioned on the front, or bumper side, of the radiator so that it pushes the air through the radiator core.

The fan is responsible for most, or all, of the airflow through the radiator when vehicles are operating at low or stationary speeds. The belt-driven fan slows down with the engine RPM, thus decreasing airflow to the radiator. It also takes horsepower from the engine to rotate, resulting in decreased engine performance, possible overheating and lower gas mileage. In contrast, electric fans maintain their speed regardless of engine RPM, providing constant, maximized airflow. The result is more effective cooling than with a belt-driven fan. Converting to an electric fan or adding an auxiliary electric fan eliminates engine horsepower drain, resulting in better engine performance and improved gas mileage.

EMP's electric water pump design is revolutionary, creating an entirely new class of water pump. The patented, fully controllable water pump uses a proprietary mixed-flow impeller and diffuser design that improves fluid pumping efficiency. An integral, liquid-cooled brushless DC electric drive motor provides flow control independent of engine speed. The diffuser immediately redirects fluid as it comes off the impeller into a stationary set of vanes, isolating it from impeller interference. This boosts efficiency because the diffuser collects fluid from the impeller for a full 360 degrees as compared to approximately 90 degrees with a conventional volute style pump.

EMP's family of advanced electric water pumps range fro 120 watts to 1550 watts in power. They're designed to run at 100 C continuously and will also operate at - 30 C. EMP's popular drag racing electric pump consumes 120 watts of power. The majority of customer requests that we are asked to fulfill fall into two temperature categories: - Operating Temperature Range - 40 C to 105 C - Storage Temperature Range - 50 C to 125 C

EMP's "thermal kits" are designed to improve fuel economy by 3 - 5%, improve reliability and serviceability, reduce maintenance time and cost and improve the temperature control of powertrain fluids. The kit will consist of electric coolant pumps, electric fans, electronic thermostat, optimized radiators and heat exchangers, along with a feedback control system. A new advanced technology air-cooled alternator will replace the existing oil-ccoled alternator to provide power for all electrical loads. Replacing the mechanically/hydraulically driven cooling system components with optimized, electrically powered devices will reduce the horsepower draw on the engine by over 75%, under full load conditions.

If properly installed and maintained, Oil Mate will NOT void your engines warranty.

It depends on the application. A typical genset application extraction cycle would be every 1-minute, an OTR truck would be every 6 minutes, and a Humvee would be every 12 minutes. The smaller the sump size, the longer the cycle times.

No, it is not. All that is required is a 12V or 24V-power supply, as the OilMate has a built in controller.

No, it is not. The used oil is sent to the fuel return line where it is blended with the fuel and then sent to the fuel tank.

The system can be used in all diesel engines.

The system has been EPA certified by Cummins; EPA aftermarket regulations hold if a system has been certified on an engine of similar size.

The Oil Mate kit includes valve, controller, and wiring harness. There is an optional make-up tank kit, which includes a 5 gallon tank and an oil level sensor (alerts operator when oil level in make-up tank falls below a certain level).

It is generally determined by fuel consumption, the service interval requirement, engine size and lube system capacity.

The best way to answer this question is to ask more questions of you. Are you frustrated with; poor battery life? Premature alternator failure? The Power 450 offers several advantages over the competition. Our available current at idle RPMs exceeds 260A. Anticipate your battery life to increase substantially if you spend much time at idle conditions. The Power 450 also runs substantially cooler than other air cooled alternators; heat is the catalyst to failure. The Power 450 is equipped with oversized sealed, greased for life bearings. It is simply the best performing, competively priced alternator in this market.

The Power 450 alternator can use the Delco Remy 50DN pulleys; else, EMP offers an 8 and 12 groove pulleys.

The Power 450 alternator uses an off-the-shelf Delco Remy Voltage Regulator.

The voltage regulator can be remote mounted in any desirable location.

The Power 450 uses a cradle mount, the same cradle that holds a 50DN or CE Niehoff 703 on Detroit Series 50s and Cummins ISL, ISM, or L-Gas engines. However, if your running a CAT C9 , EMP offers a modification kit that will allow a bolt-in application. The Power 450 will NOT fit in a Detroit Series 40 engine platform.

Any air cooled alternator would benefit from running cool clean air through it. Dirt clogs the air passages of an alternator which limits cooling and ultimately destroys the alternator. The Power 450 is the only alternator in the market that comes standard with an Independent Air Intake System allowing the alternator to consume cool clean air which increases the performance and durability of our product.

Right now we have 17 distributors with over 100 locations across the United States. Also, we will have inventory to overnight ship in an emergency.

Extensive component level (thermal shock, vibration, corrosion, high temperature durability, rotor over-speed, temperature/speed/load voltage regulation, etc.) as well as, in vehicle application testing has been completed. No less than 10 bus municipalities throughout North America have tested and continue to test the Power 450 in real world conditions.
