The RPP uses EMP's 28V Power 450 or Power 535 brushless alternators. The EMP alternators offer high efficiency and have oversized bearings for robustness and long life. With over 20,000 units in the field, EMP alternators have been proven since 2008.

The RPP has been specifically designed to generate DC power for auxiliary loads while saving valuable space under the hood of refrigerated trucks/trailers, work trucks, and emergency vehicles. The RPP mounts to the chassis of the vehicle using bolt-on brackets and is powered by the transmission's power take off. Optional custom brackets are available upon request.

The RPP is a fully integrated product designed to generate significant 28V DC electrical power, when mated with a vehicle transmission''''s PTO output shaft.

The RPP's machined ductile iron casting receives a premium powder coat finish to handle the toughest underbody environments. The casting includes threaded mounting bosses to accept a variety of vehicle mounting bracket designs.

The RPP''s shaft is machined from a high quality shaft steel. It has a 1.25" diameter keyed shaft to mate with the PTO output shaft. Both bearings, the 10 groove drive pulley and a splash shield are pressed onto the shaft. The 10 groove drive pulley diameter is designed to optimize the RPP power generation, given a 1:1 PTO drive ratio and vehicle RPM range. EMP offers additional pulley diameters to adapt to differing PTO ratios.

The RPP uses the highest quality NSK sealed bearings for this product. The bearing sizes and material specifications have been specifically chosen for this demanding application.

The RPP includes a splash shield to protect the PTO drive end bearing from the underbody water spray and contamination. The 10 groove drive pulley design includes unique geometry to prevent water and contamination from contacting the bearing.

The RPP’s belt line geometry, alternator drive belt and belt tensioner have been designed by an OEM belt and tensioner supplier. The RPP uses a commercially available belt tensioner to control the belt tension. A long life 10 groove poly-rib belt is also included with the RPP.

The RPP includes a powder coated steel belt guard to cover the critical pinch points in the belt wrap.
