CAPS AL SERIES OIL-FREE SCROLL COMPRESSORS – SAVE UP TO 25% IN ENERGY COSTS

WILLIAM CHAN
PRODUCT MANAGER GAS AND SPECIAL PROJECTS, ENGINEERING

Energy savings are based on a pyramid control process. CAPS AL scroll compressors consist of modules that offer flexibility for varying air demand conditions.

WHY OIL-FREE SCROLL TECHNOLOGY?

Compressed air oil vapour is the most difficult element to separate effectively. Filtration does not offer a complete oil vapour removal. Therefore, the most effective approach is to eliminate compressor oil in the compression process in the first place.

CAPS oil-free scroll compressors are developed to operate without the use of any oil during the compression process, resulting in “Oil-Free” grade compressed air.

It can easily achieve ISO 8573.1 air quality by pairing up with an appropriately selected dryer and filtration system. As there is no oil in the compression process, condensation treatment is unnecessary, which saves on operating costs. CAPS oil-free scroll compressors compliance to ISO8573-1 Class 0 Standard by TUV Germany.

PRINCIPLES OF AN OIL-FREE SCROLL COMPRESSOR

As demonstrated in the diagram, there is a pair of stationary and orbital scrolls
within each airend. The orbital scroll compresses feed air from the outer rim
along the stationary scroll towards the discharge port at the centre of the scroll
airend.

AL SERIES FEATURES:

  • OPTIMISED SCROLL AIREND
    The scroll airend is designed for optimum performance to match the varying air demands of your plant.
  • CORRUGATED AFTERCOOLER
    High-performance aftercooler and cooling fan enable the compressor to produce optimised compressed air.
  • SUCTION FILTER UNIT
    Offers 99.9% of dust elimination and provides a clean, compressed air supply.
  • STEP-DRIVEN DEMAND CONTROL
    Automatically operates the appropriate number of scrolls to match your air usage demands.
  • HEAVY-DUTY SIROCCO FAN
    Cools the scroll airend and the 2-way cooling method of the aftercooler offers stable operation at a maximal ambient temperature of 40°C.
  • ROTARY (TIME-SHIFTING) CONTROL PROCESS
    Used to offer sequential operation as programmed for the operation time to balance the average usage hours and to maximise the overhaul cycles.
  • ENERGY EFFICIENCY
    Energy savings through a sequential controller. By sequentially starting the series of airends, the inrush or starting current affecting the peak loading is minimised.
