Compressor Element
The quality of a compressor can be measured through the reliability, efficiency and durability of the compressor element used. Through decades of expertise in the design of compressor elements, the result is the production of most efficient and reliable compressors in the market. When the screw element is efficient durability excels, maintenance intervals decrease and fuel consumption goes down.
The CPS 650-250 compressor utilizes a Chicago Pneumatic C146 element and is driven from the diesel engine.
Inlet air is filtered through a heavy duty two stage air filter.
Air/Oil Separator
Air and oil separation is achieved through a centrifugal oil separator combined with a filter element. Separators are ASME/CRN approved versions and are stamped accordingly.
Designed for a higher maximum working pressure, the separator is equipped with a sealed high pressure safety relief valve, sonic nozzle, automatic blow-down valve, and pressure regulator.
Cooling System
The cooling system consists of integrated side-by-side aluminum oil cooler with axial fan to ensure optimum cooling. The fan is protected by a guard for operator safety. There is an access port at the front of the machine for easy cleaning
The cooling system is suitably designed for continuous operation in ambient conditions up to 120°F, with canopy doors closed.
John Deere
John Deere 6068HFC08 Tier 4 Final, turbocharged, six-cylinder, liquid-cooled diesel engine provides ample power to operate the compressor continuously at full-load.
Meets all US EPA and Environment Canada exhaust legislations with Tier 4 Final compliance. The US EPA engine family is “FJDXL06.8302”
The engine utilizes a Diesel Particulate Filter (DPF) with active regeneration, a Diesel Oxidation Catalyst (DOC) and a Selective Catalytic Reduction (SCR) system to help meet Tier 4 Final emissions. All functionality of the engine and exhaust after treatment are controlledautomatically on the XC2003 controller.
Engine output at rated speed, in accordance to SAE Standard, is 250hp at 2100 rpm.The engine has the capability to start the compressor to -13°F (-25°C) with standard glow-plug aid, synthetic compressor oil and 120V blockheater.
The 88 Gal (333L) fuel tank is sufficiently sized to operate the unit for minimum of 8 hours at full-load condition. As well the unit requires Diesel Exhaust Fluid (DEF). There is a DEF tank sufficiently sized to operate the unit for a minimum of 24 hours.
Instrumentation
The John Deere 6068HFC08 after treatment consists of a Diesel Oxidization Catalyst (DOC), passive Diesel particulate Filter (DPF) and Selective Catalytic Reduction (SCR). The SCR utilizes the temperature of the exhaust to passively regenerate during normal use.
