2020 Atlas Copco QAS 330 JD T4F
JD Tier 4 Final, turbo charged, intercooled, six-cylinder, liquid-cooled diesel engine provides ample power to operate the
generator continuously at full-load.
Meets all US EPA, CARB and Environment Canada exhaust legislations with Tier 4 Final compliance. The engine utilizes a Selective
Catalytic Reduction (SCR) and Diesel Exhaust Fluid (DEF) to meet final Tier 4 emissions. All functionality of the engine is controlled
automatically on the controller.
The engine has the capability to start the generator at 14°F (-10°C) with standard glow-plug aid. Cold start options are available for machine
starting for down to -13°F (-25°C).
The 385 Gal (1457L) fuel tank is sufficiently sized to operate the unit at full-load condition for long run times (see the Technical Data table for
The engine operates on a 24V negative ground electrical system with a charging alternator and lockable battery cutoff switch.
The cooling system is suitably designed for continuous operation in ambient conditions up to 122°F (50°C), with canopy door closed
QAS 330 come equipped with a DeepSea 7310 control module. This is a fully diagnostic ECU controller with large 3”
display, that is intuitive and easy to operate with all functions conveniently at your fingertips. The controller also manages the engine ECU
operating system, and a number of safety warnings and shut downs on various parameters (listed below).
The controller is powered by a main On/Off switch located next to unit.
