KIRLOSKAR PNEUMATIC HEAVY DUTY REFRIGERATION COMPRESSORS 'KC' SERIES

      APPLICATIONS :

KC reciprocating compressors are most suitable for industrial refrigeration and low temperature
applications. They are designed to operate with ammonia, halocarbons and other refrigerants. Ideally
suitable for continuous duty, process refrigeration, liquification plants, ice plants, cold storage, etc. They are available in Single Stage as well as Two Stage versions. All welded steel construction,
built-in, unloaded starting device and the safeguard against incidental liquid hammer are salient
features of these compressors. Over 5,000 KC compressors have been operating successfully round
the clock in India and abroad.

• WELDED STEEL CRANKCASE.
• PISTON / CONNECTING ROD ASSEMBLY.
• CRANKSHAFT AND MAIN BEARINGS.
• CYLINDERS AND SUCTION VALVE LIFTING.
• OIL PUMP AND FILTERS.

• DISCHARGE VALVE ASSEMBLY.
  
  
  
  

  * WELDED STEEL CRANKCASE : Apart from being low in weight and ensuring rapid heat dissipation, the crankcase is absolutely gas tight and impact proof. The smooth infernal surfaces guarantee the good

  * PISTON/CONNECTING ROD ASSEMBLY : The Alluminium piston is fitted with 3 compression and 2 oil scraper rings for perfect sealing and low oil consumption, S.G. iron connecting rod is drilled through for pressure lubrication of the piston pin. It has steel backed, white metal shells on its big end and bronze bearing on its small end. The complete assembly can be removed from the top for servicing without withdrawing the cylinder liner.

  * CRANKSHAFT AND MAIN BEARINGS : The bearing surfaces of S,G. iron crankshaft are ground to fine tolerances. The main bearings are white metal lined, steel backed bushes pressed into the cast iron bearing covers. Intermediate bearing blocks are provided with split type bearing shells of the same type. Each crankshaft is dynamically balanced together with the counterweights.

  * CYLINDERS AND SUCTION VALVE LIFTING : The interchangeable cylinder liners are made of fine-grained, centrifugally cast, alloy iron. Fine boring and honing result in a mirror-smooth running surface. Loading or unloading of the cylinders is achieved by a hydraulic mechanical suction valve lifting mechanism on each individual 'cylinder. For unloading, the suction valve ring is lifted from its seat in the cylinder collar by spring tension. Loading of the cylinder is effected by admitting control oil pressure to the control piston, allowing the suction valve ring to descend on its seat.

  * OIL PUMP AND FILTERS : The single gear pump, driven directly by the crankshaft, incorporates a differential pressure regulator to provide separate pressures for two oil systems : lubrication system and control oil system. The pump also includes an automatically operating hydraulic delay valve, ensuring complete unloaded start. A metal gauze suction filter element and a throw-away paper discharge filter cartridge provide for extreme filtering capacity of the lubricating oil.

  * DISCHARGE VALVE ASSEMBLY : Three concentric discharge valve rings ensure ample gas passage at low lifting height. The use of sinusoidal springs in place of coil springs, together with precision machined and lapped surfaces, result in a trouble-free operation for a remarkably long time.
