Description
Design
Features:
1.Chilled Glycol in/out
*5/**0°C; cooling water in/out *0/*5°C
2.This series of units used
in low temperature conditions,*5% ethylene glycol to be used as a
refrigerant such as antifreeze;
3. Power supply:
3P***0V**0HZ;with voltage allowance ±*0%,voltage dif between the
phase lines±2%;
4.The data above is for
R*2, contact us if that for R**4a,R**7c and other refrigerant
need;
5.There may be Changes for
improvement without notice, confirm always before your
order.
SYSTEM
FEATURES:
- Twin screw compressors of
world famous brand is adopted, with high efficiency, low noise
level, less wearing and long operation time.
- The unit is of high
performance as they are made of the condensers and evaporators of
grooved copper pipes, and high quality components, by specialized
process.
- The unit is easy to
operate, and friendly interfaced.
- The energy saving for
Multi-capacity regulation resulted in cost cut down for operation
and maintenance.
SYSTEM
CONTROL:
- Imaged system operation
chart, showing the temperature of water in/out, the energy level of
compressor run, on/off button, run time, alarm etc. And the remote
turn on/off function is available. PC remote control is
optional.
- Notice for maintenance is
indicated according to the accumulated run time of the
compressor.It is convenience to maintenance.
- The control system will
automatically balance the run time for each compressor for
mult-compressor unit.
SAFETY
PROTECTION:
1. Discharge check value:
it prevents the discharged gas from going back after the compressor
stops.
2. Phase lack protection:
It protects the compressor for over high voltage, voltage
deficiency, and phase lack.
3. Direction protection: It
protects the compressor from damage resulted from Counter direction
run.
4. Oil heater: It heats the
oil before the unit start, keep the good lubrication for the unit
before it runs.
5. Overheat protection
inside the motor of the compressor: It protects the compressor from
burning down for too high coil temperature for overload, or
abnormal run condition.
6. High&low pressure
protection: It protects the compressor and system against extreme
run condition and trouble. Freezing protection:It protects the unit
form too low temperature of the water out, freezing may occerat
some place,resulting in freezing breaking of the
evaporator.
7. Water flow protect: It
protects the unit from run without water flow.
8. High temperature of
chilled water protection: It works to protect the compressor in
case that the load is too large,the temperature of chilled water is
too high. It may result in compressor failure without this protect
in the case.
