Air-cooled screw chillers have significant advantages in scenarios
with multiple injection molding machines. They can meet the
efficient cooling needs of multi-machine collaborative production
while taking into account energy saving and convenient operation
and maintenance. The following are its core benefits:
1. Centralized and efficient cooling, cost saving
One machine with multiple controls: A single air-cooled screw
chiller can provide centralized cooling for multiple injection
molding machines (need to match the total cooling capacity
requirements), avoiding repeated investment in each injection
molding machine with a separate chiller, and reducing equipment
procurement and installation costs.
Energy saving and consumption reduction: The screw compressor
supports multi-stage or stepless energy regulation, and can
automatically match the cooling output according to the real-time
load of multiple injection molding machines, avoiding "energy
waste" at low load, and the comprehensive energy efficiency ratio
(COP) can reach 3.0~3.5.
2. Stable temperature control to improve injection molding quality
Precise temperature control: The water temperature fluctuation can
be controlled within ±1℃ to ensure uniform cooling of the mold and
reduce defects such as shrinkage, warping, and flow marks caused by
temperature differences in injection molding parts.
Quick response to load changes: The intermittent operation of the
injection molding machine (cycled mold opening and closing) causes
large fluctuations in heat load. The impact resistance and
frequency conversion technology of the screw compressor can quickly
respond to changes in cooling demand and maintain stable water
temperature.
3. Save space and simplify installation
Integrated design: The air-cooled unit does not require an external
cooling tower and water pump, and occupies a small area, which is
especially suitable for workshops with limited plant space.
Quick deployment: It only needs to connect the cooling water
pipeline and power supply to operate, and supports multiple
injection molding machines in parallel (distribute the flow through
the water distributor), shortening the production line
transformation cycle.
4. Low maintenance and high reliability
No dependence on water quality: The air cooling system does not
need to deal with problems such as scale and algae, avoiding the
decrease in heat exchange efficiency or pipe blockage due to poor
water quality (the injection molding machine mold cooling channel
is narrow and sensitive to water quality).
Long life design: The screw compressor has a stable structure and
an operating life of more than 10 years, which is suitable for
injection molding workshops with 24-hour continuous production.
5. Adapt to multiple scenarios and environments
Advantages in water-scarce areas: completely dependent on air
cooling, no cooling water consumption, suitable for areas with
water shortage or strict environmental protection requirements.
High temperature environment resistance: The optimized air-cooled
unit can operate stably at an ambient temperature of 45°C (by
strengthening the fan or increasing the condenser area), avoiding
the cooling capacity attenuation caused by high temperatures in
summer.
6. Flexible expansion and intelligent management
Modular expansion: If the number of injection molding machines is
increased in the future, the capacity can be flexibly expanded by
connecting multiple chillers in parallel or upgrading
large-capacity units.
Intelligent monitoring: Supports remote control, fault warning and
energy efficiency analysis, facilitating multi-machine
collaborative management.
