When we first heard of Warn's new PowerPlant Dual Force, we weren't that impressed. "Packaging an air compressor with a winch? So what?" Boy, were we wrong! That first impression was in error and the result of our ignorance of this great new product. When we actually saw the unit and learned of its capabilities, that initial indifference quickly turned to excitement. What Warn has done is brilliant! Instead of merely packaging a winch and an air compressor together, the company has integrated a high-capacity compressor to use the same electric motor already utilized to drive Warn's incomparable winches.
The Warn PowerPlant Dual Force is available in two models: the PowerPlant HP and the PowerPlant HD. The PowerPlant HP is targeted at the Jeep/SUV/light truck market with a rating of 9,000 pounds and the rapid line speed to which we have become accustomed as users of Warn's quick winches. The HP features 125 feet of 5/16-inch wire rope. The Powerplant HD is better suited for users with fullsize trucks as it is rated for 12,000 pounds and includes 80 feet of 3/8-inch wire rope.
All other features, ratings, and specifications are the same. Both units employ Warn's Gen II 4.6hp series-wound motor. The winches are equipped with weather-resistant sealed contactors instead of solenoids for high reliability. The HP and HD include Warn's exclusive thermal-protection switch which protects the motor from overheating damage during prolonged usage. The different line rating between the two units reflects the difference in reduction gearing and the resulting line speed.
The choice between the HP and HD is purely "need-based" as the price for the two units is also the same. We should also point out that the price is very favorable when compared to the combined cost of stand-alone winches and air systems.
"But what about the air system?" Ah, yes! The air system is the heart of this exciting product. The compressor puts out a whopping 12 cubic feet per minute (cfm) at 0 psig and, more importantly, 5 cfm at 90 psig. The maximum pressure, limited by a pressure switch, is 100 psig. The PowerPlant unit also includes a trick finned aluminum aftercooler/reservoir tank. The aftercooler is effective enough that a plastic air line can be used on the outlet of the tank without temperature concerns.
The air compressor is driven by the same 4.6hp motor used to power the winch. A selector switch on the front of the unit is used to disengage the winch during compressor operation. The air compressor is linked to the drive motor via a belt to allow the compressor to run at an optimal speed, enhancing reliability. The compressor uses a Teflon lip seal between the aluminum bore and piston. The seal is replaceable, although any need to replace it is not expected. The aluminum bore is hard-anodized to further increase durability.
