-5 ℃ Single Compressor Water Cooled Screw Type Water Chiller Unit
Hanbell Water Chiller Units Features
Compressor
Select semi-closed 5:6 asymmetric twin-screw compressor from
world-renowned brand. The possibility of shaft seal leakage is
zero. Using a rotating exhaust design, the lastest development of
the fourth generation line, optimize the circumference speed,
excellent design of gear so that the unit has higher compression
efficiency. Motor chamber compression chamber integrally cast, high
precision. Double pressure compensated rotor housing, very strong,
no expansion even in the state of high pressure, and it effectively
reduces the noise.
Heat exchanger
The condenser and evaporator of this series unit adopts shell and
tube heat exchanger, using new high efficient heat exchanger
structure. Heat exchanger adopts the most advanced and effcient
heat exchanger tube bundle with unique geometric characteristics
and enhanced tube nucleate boiling required vaporization core,
strengthen the fluid in the tube and delay perturbationat the same
time, the water side fouling, heat transfer enhanment, the inside
wall in order to get the best performace, comparade to the previous
design, the unique design of the heat transfer efficiency is
increased by 30%.
Evaporator evapotation tube with inner grooved on outer concave
tooth enhanced heat transfer technology, condenser tube with inner
grooved cutter teeth technology, improves the evaporator and
condenser heat transfer efficiency and the evaporation temperature,
and improve the energy efficiency ratio for the unit.
PLC
A good Chinese-English interactive interface is to achieve
automatic control function before the LCD display real-time statues
of the machine work, precise monitoring unit operating at optimun
state, the touch pannel sealed, waterproof, dustproof,
corrosion-resistant, long-key life. Equipped with cooling pumps,
cooling water pumps and cooling tower fan interlock control
function.
