Water-cooled Screw Compressor Industrial Chiller With CE
Certification
Feature:
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.
Features of the compressor:
1. 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.
2. High efficiency 5-to-6 rotor profile patent.
3. Capacity control apply to four-step
(100%-75%-50%-25%),three-step (100%-66%-33%) and no step control
system.
4. With 11 bearings and a balance piston against axial thrust. This
extends longer bearings life 2.5 to 3.5 times than traditional
design.
5. 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.
6. Built-in oil pressing system ensure compressor maintaining the
optimal lubricity without oil pump.
7. High efficiency double filtration oil separator ensures maxinum
heat exchanger.
8. Efficient, low noise and small vibration.
9. Various options of refrigerants, R22, environment-friendly
R134A, R407C etc.
10. 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.
