RigMaster Power’s auxiliary power unit has been upgraded for 2006, with new options added as well. The improved APU, says RigMaster, will
bring reduced maintenance, easier serviceability, and shortened installation times.

“We focused on finding ways to do things smarter” says Ken Tchir, the company’s operations manager, adding that preventive maintenance costs can be cut by up to 50%.

Among the more significant changes is the new larger-capacity oil pan which will extend maintenance intervals. There is also an enhanced
cooling system and controller software upgrades. Sporting a new universal mounting system that will improve compatibility with all class 8 trucks and a new factory-installed integral muffler, installation for the new models should be cut by 15%.

Rigmaster is offering the 2006 model with a two-year, 4,000-hour comprehensive warranty, up from the previous one-year, unlimited-hours coverage.

New optional upgrades include a 13-hp Caterpillar engine, though the APU standard engine will continue to be the Perkins 400. The AutoStart feature remains an option but it’s been upgraded to include fully automatic low-voltage battery monitoring, along with date and time automatic-start programming and automatic temperature-control startup/shutdown.

Other changes implemented in 2005 include an increase in generator power to 6,000 watts, a 60-amp alternator, a dual engine fan system, and
all-weather coatings for most components.
