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 250-100 MP compressor utilizes an Chicago Pneumatic C90 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. Vessel is ASME/CRN approved and stamped accordingly.
Designed for a higher maximum working pressure, the separator is equipped with a high pressure sealed and certified safety relief valve, automatic blow-down valve
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 for easy cleaning of coolers.
The cooling system is suitably designed for continuous operation in ambient conditions up to 114°F (45°C) and 110°F (40°C) with AC, with canopy doors closed.
Kubota
Kubota V2403 CR-T-E4B, turbocharged, four-cylinder, liquid-cooled diesel engine provides ample power to operate the compressor continuously at full-load.
Cold start options are available for up to -4°F (-20°C). The 23 Gal (87 L) fuel tank is sufficiently sized to allow full shift autonomy (8h).
Instrumentation
The instrument control panel is located at the rear of the compressor canopy with easy access. The standard instrument package includes an operating pressure gauge, a starter switch, a running hour counter, and 2 warning lamps.
The starter switch has an integrated lockout mechanism to prevent starter motor damage.
