CNCEN BRAND Water Cooled Screw Chiller :

The ZCS-xxAS Series Air Cooled Screw Chiller : World famous brand screw type
compressor equipped with the high-efficiency-copper tube condenser and
evaporator, together with famous brand control components so as to ensure the
small size, low noise, small vibration, large energy, long service life and convenient

operation. Elegant design, excellent reliability and high-quality
performance make it outstanding in the refrigeration field.

● World famous brand new type and high-efficient screw-rotor compressor,

with efficiency 20%~30% higher than those common ones. It has obtained

several patents of Europe and America countries and passed the international

quality certification of ISO9001.

● High efficiency 5-to-6 rotor profile patent.

● Capacity control apply to four-step (100%-75%-50%-25%),three-step

(100%-66%-33%) and no step control system.

● With 11 bearings and a balance piston against axial thrust. This extends

longer bearings life 2.5 to 3.5 times than traditional design.

● Designed with efficient silicon steel and special slots , and equipped with the inside

and outside all around design to cool the flow channel so to ensure maximum efficiency

of the compressor motor under any load.

● Built-in oil pressing system ensure compressor maintaining the optimal lubricity without

oil pump. High efficiency double filtration oil separator ensures maximum heat exchange.

● Efficient, low noise and small vibration.

● Various options of refrigerants, R22, environment-friendly R134A, R407C etc.

● All-wave compressor volume ratio(Vi=2.2/2.6/3.0/3.5) for selection to avoid the extra energy

consumption caused by over or under compression.
