Saving energy with CAPS AL Series oil-free scroll compressors

The AL Series scroll compressors from Caps Australia consist of modules
that offer flexibility for varying air demand conditions.

Oil-free scroll technology

Oil vapour in compressed air is the most difficult element to separate
effectively because filtration does not offer complete oil vapour removal. The
most effective approach, therefore, is to eliminate compressor oil in the
compression process.

CAPS’ oil-free scroll compressors are designed 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.

The absence of oil in the compression process eliminates any need for
condensation treatment, helping save on operating costs. CAPS oil-free scroll
compressors are compliant with ISO8573-1 Class 0 Standard by TUV Germany.

Principles of an oil-free scroll

Each airend has a pair of stationary and orbital scrolls. 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.

CAPS AL Series oil-free scroll
compressor 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% dust elimination and provides a clean, compressed air

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, while the 2-way cooling method of the
aftercooler offers stable operation at a maximal ambient temperature of 40¡C.

Rotary (time-shifting) control

Offers sequential operation as programmed for the operation time to
balance the average usage hours and 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.
