85HP Screw Type Chiller Central Chiller Air Cooled Industrial Plastic Chiller Packaged Air Cooled Chiller For Packaging Production Line
In the packaging industry, after the plastic packaging is heated,
the food and medicine on the production line need to be packaged.
The chiller can reduce the temperature to the appropriate packaging
temperature in the shortest time, thereby greatly improving the
work efficiency.

Features of Anges air-cooled screw industrial chiller
1. The air-cooled condenser is a fin type, made of double-oil
corrugated hydrophilic aluminum platinum, manufactured by heat
exchanger processing equipment, and equipped with a low-speed
large-leaf axial flow fan, which can reduce operating noise and
reduce the impact on the surrounding environment. Influence.
2. The unit control system adopts PLC program controller, and the
human-machine interface is equipped with a large-screen touch
screen. The interface is simple and generous, and the operation is
intuitive and easy. 3. The unit has reliable protection devices,
including: high and low voltage protector, exhaust overheat
protector, compressor motor overheat protector, overload current
protector, antifreeze temperature protector, water flow protector,
emergency stop switch, temperature sensing type Fusible bolts,
safety valves, etc.
Why air-cooled chiller has high pressure alarm?
In hot summer, many air-cooled chillers have high pressure
alarm,especially in areas with relatively high temperatures which
can be above 45℃, such as Saudi Arabia, the United Arab Emirates,
Iraq and so on.
General air-cooled chiller is equipped with a full set of
protection devices, when the chiller appears high pressure alarm,
it will automatically start the protection device, and the
corresponding fault indicator light will be lit.
The high pressure alarm of the air-cooled chiller is triggered by
the poor cooling effect of the condenser.If this problem is not
fixed and keep running the chiller at high pressure for a long
time, it will cause the current to be too large and burn the
compressor.
The reasons for the chiller high pressure alarm are as follows:
1. Air-cooled chiller’s condenser rely on fans to dissipate
heat.When the ambient temperature is above 42 degrees, the heat
dissipation of the condenser is poor, that is, the heat generated
by the refrigerant circulation cannot be taken away by the fan.
2. The condenser is dirty and blocked, which will also cause poor
heat dissipation and lead to high pressure alarm.
Solution:
1. Check whether the fan works properly.
2. Make sure there’s good ventilation to exhaust hot air smoothly.
3. If the ambient temperature is higher than 42 degrees, use a fan
or cooler to cool down the temperature around.
4. Periodically remove the air filter to clean the fins or clean
the fins with high-pressure air.
5. If the ambient temperature is around 42 ℃, need to increase the
condenser size to improve heat dissipation efficiency.Normally, we
will increase size to 25% for chiller using refrigerant R22, R407c,
R410a.
If ambient temperature higher than 45 ℃, we suggest to design the
chiller with R134a which can be used at ambient temperature of 50
℃.The disadvantage is that the cost is relatively high, because its
refrigeration efficiency is only 65% compare with other
refrigerants, in order to achieve the same cooling capacity, you
must use a larger compressor.
P.S. The installation of air-cooled chiller should choose the right
location to ensure that the installation environment is well
ventilated.
How to select the model of the chiller ?
- We need to know the heat load of your process or chiller cooling capacity.
- Required water temperature, water pressure and flow rate.
- Application and power supply in local.
- Max. Ambient temperature in summer day
- Customized special specifications are acceptable. Contact us for more chiller Specification by number +86 13923791048.
