The X4 series is designed to outperform other platforms
while using less engine power. It’s a paradigm shift to
deliver more with less, and that’s exactly what the X4 series
achieves: higher refrigeration capacities, better performance,
and greater fuel efficiency, all while using less power.
The X4 platform features a smarter large-displacement
2.2-
liter engine equipped with enhanced sensors and
an electronic control module. The engine continually
communicates with the APX Control System to optimize
performance and eliminate wasted power.
The result: an ultra-high-efficiency platform that generates
higher capacity and performance using significantly less
power. That means X4 engines operate using fewer run hours
at lower speeds, increasing their durability and reliability.
