WORLD WIDE SUPPORT

Globally recognized industrial presence

Over the last sixty years, Kaishan has steadily grown to become a signi?cant and diversi?ed engineering company developing high value machinery for industries worldwide. With modern, specialized manufacturing facilities positioned in seven strategic locations, Kaishan’s group of thirty-two subsidiary companies produce over 1,00,000 rotary screw and 2,50,000 reciprocating compressors annually. Kaishan is the world’s third largest manufacturer of Compressed air equipment, mining and drilling equipment and supports industries in more than 60 countries including USA, Australia, Germany, Japan, Korea, Russia, Africa and throughout Latin America.

Vertically integrated global strategy

Kaishan’s global strategy of combining highly skilled engineering with highly efficient manufacturing allows us to provide performance proven and reliable equipment at a signi?cant cost savings to our customers. Additionally, Kaishan’s manufacturing processes are 85% vertically integrated ensuring full control of the material supply chain. This approach enables to supply high quality components at a lower cost and maintain agility to respond rapidly to changing market demands.

Environmental sustainability

Integral to the design and manufacture of our products is outstanding energy efficiency. Kaishan’s fundamental belief in environmental sustainability drives us to produce products that maximize energy efficiency and help to preserve precious energy resources. Single and two-stage compressors that produce more compressed air per unit of power input as well as expanders that utilize waste heat to produce electricity are just two of the fundamental products in our sustainable approach.
Throughout our manufacturing processes, unused waste materials are recycled at every stage to maximize the use of raw materials. This approach translates to lower initial costs and lower operating costs for our customers and a smaller environmental footprint that helps us all. Kaishan’s committment to environmental responsibility ensures that we will continue to develop technologies and manufacturing solutions that provide industry with "Good and Green" products of exceptional value - now and well into the future.

Air is free, Compressed Air is Not!

Compressed Air is the Fourth Largest Utility for an Industry after Electricity, Gas and Water. Very few people understand the cost associated with compressed air production. Compressed air is the most expensive form of energy used in an industry.

Energy Cost

Consider a compressor of 500 cfm and 100 psi (g). This will use a 100 HP / 75 kW motor. Running for 24 hrs a day, 365 days a year, with a 70% load factor, it would consume approximately 600000 units annually. At Rs 7 per kWh, it would cost 42 lakhs a year. That is 3-4 times the cost of the compressor itself.

INTEGRATED MICROPROCESSOR CONTROLLER

  • Easy to use with mimic diagram
  • Constant readout of pressure & temperature
  • Selective readout of operation & maintenance parameters
  • Safety shutdown
  • 24 hours automatic start-stop operation
  • Lead/Lag & Sequencing multiple compressors
Image

ELECTRICAL CONTROL PROTECTION

  • Protection against ‘Single Phasing’
  • Phase sequence protection
  • High discharge temperature shutdown
  • Auto-dual control: If there is no air demand, the
    controller will unload the compressor and then
    shut down the drive motor. The controller will
    restart the compressor when the system pressure
    drops to the preselected pressure level

HIGH EFFICIENCY DRIVE MOTORS

  • IEC high efficiency TEFC IP55 motors
  • High temperature F class insulation
  • Direct coupling design for extended bearing life
  • Easy Maintenance with grease re?ll port
    ‘No load start’ protection. Automatic blow down
    during unload before shut off ensures the
    compressor does not start on load

EFFICIENT SKY ROTOR PROFILE

SKK series rotors are highly efficient and their world renowned 5/6 pro?le have evolved from previous generations to meet today’s industry requirement. Energy & Cost efficiency with increased output is achieved through following:

a) Large rotor size
To increase the rotor throughput, the Airends of our compressors are larger than usual. Hence our Air Compressors are built with 5/6 lobes with a larger rotor size than the traditional pro?le. Therefore, they consume lower speci?c power (kw/cfm ratio).
Image
b) Lower inter-lobe leakage losses
Greater the number of lobes, smaller is the pressure difference between the two neighboring working chambers thereby reducing inter-lobe leakage losses. Hence leakage to delivery ratio decreases as the number of rotor lobes is increased.
Image
c) Large wrap angle & discharge port
A greater number of lobes combined with a large wrap angle ensure multiple rotor contact. This reduces vibration & thus minimizes noise. Larger discharge ports decrease the discharge velocity and therefore reduce the discharge pressure losses, thereby increasing the compressor overall efficiency.

SUPERIOR FILTRATION SYSTEM

  • Ultra-efficient inlet air ?lters provide clean air that
    traps dirt particles to less than 3 microns
  • Easy spin-on Oil Filters
  • Pressure differential gauges for easy ?lter

COMPRESSOR FLUID & COOLING SYSTEM

A custom blended PAO synthetic hydro-carbon fluid provides:
  • Premium lubrication at high and low temperature
  • Reduced volatility properties
  • Long life lubricant formulated with rust and
    oxidation inhibitors

6000 hours fluid pre-filled with standard units

Superior Cooling system designed for environments with high ambient temperature and humidity levels

KRSD SERIES COMPRESSOR WITH VFD

KRSD compressors are built to be compatible with optional VFD feature.

KRSD maximum efficiency with consistent operation. Unlike the traditional “Auto-dual” and “Load/ No load” control modes, KRSD VFD modulates the speed of the drive motor in response to system demand. This results in greater energy saving compared to a ?xed speed compressor. The VFD feature greatly reduces the starting power surge
of the motor. A constant pressure delivery extends the life of valves. Variable Speed Air compressors provide
