How to Choose Topstar Auto Cooling System for Injection Molding Production?

2026/04/24 By le zhan

Auto Cooling System

Topstar offers two types of auto cooling system: water-cooled chillers and air-cooled chillers. Both models feature a modular design that reduces weld points by 60%, minimizes refrigerant leaks, and improves reliability. Both products are equipped with intelligent control features, including a 7-inch touchscreen, timed start/stop, and RS485 and MODBUS communication. They differ in structure and heat dissipation and absorption characteristics, allowing selection based on factory conditions, production scale, and cooling requirements.

How does Topstar’s auto cooling system meet different needs?

Our auto cooling systems fall into two main categories: water-cooled chillers and air-cooled chillers. Air-cooled chillers are suitable when factories require easier installation, relocation, and no water supply connection. They are a practical choice for workshops prioritizing mobility or those with frequently changing layouts. Furthermore, air-cooled systems are generally easier to maintain in environments with limited water infrastructure or where customers prefer a more independent solution. Water-cooled chillers are preferable if your factory has an ample water supply and requires high cooling efficiency, stable operation, and strong heat dissipation performance. In many industrial environments, water-cooled chillers are the preferred choice for production lines with high production demands or requiring more stringent thermal management.

Comparison of Cooling Structures and Heat Absorption Modes of the Two Types of Water Chillers

Topstar’s two types of water chillers feature different heat-dissipation and heat-absorption structures, each suited to different production scenarios.

Cooling TypeHeat Dissipation StructureHeat Absorption StructureMain Feature
Air-cooled chiller (coil heat)Air-cooled heat dissipation finsCoil heat absorptionNo water connection required, easy to move and maintain
Air-cooled chiller (shell and tube heat)Air-cooled heat dissipation finsShell and tube heat absorptionNo water connection required, easy to move, high cooling efficiency
Water-cooled chiller (coil heat)Water-cooled heat dissipation shell and tubeCoil heat absorptionHigh cooling efficiency and easy maintenance
Water-cooled chiller (shell and tube heat)Water-cooled heat dissipation shell and tubeShell and tube heat absorptionHighest cooling efficiency

Air-cooled chillers use fins to release heat into the surrounding air, while water-cooled chillers use a shell-and-tube heat exchanger. Regarding heat absorption, both types of chillers can be selected for coil-based or shell-and-tube heat absorption, depending on the application.

Stable, Reliable, and Intelligent Auto Cooling System

The stability of the auto cooling system affects molding quality. Refrigerant leaks or malfunctions during prolonged chiller operation can lead to downtime and maintenance costs. Topstar directly solves this common pain point through a smart modular joint design. For one thing, this optimized modular joint design cuts welding points by 60%, which in turn greatly lowers the overall risk of refrigerant leaks. On top of that, by simplifying and reducing welding complexity, Topstar has successfully boosted the structural stability of its automotive cooling system. Beyond that, it also strengthens long-term reliable operation, letting factories enjoy quiet, steady production round the clock plus, it cuts down on the need for frequent, time-consuming maintenance work.

Protecting the Core Components of the Auto Cooling System

Both water chillers in the auto cooling system incorporate multiple protection functions. The compressors are equipped with high- and low-pressure protection and overload protection to prevent damage to core components and extend their service life. They also feature antifreeze protection to prevent the heat exchanger from freezing and cracking, helping the machine remain safe under low load or abnormal operating conditions. Furthermore, a high-efficiency evaporator is used to achieve precise temperature control, maintain stable cooling performance, and enable the machine to respond more accurately to process demands.

Integration of Intelligent Functions

Topstar’s auto cooling system features a 7-inch touchscreen for intuitive operation, real-time monitoring of temperature, operating status, and alarm information. This allows operators to easily understand the system’s operating status and respond quickly when needed.

The system also supports scheduled start/stop programming up to one week in advance. Factories can plan cooling system operations based on shift schedules, production times, or standby requirements, avoiding unnecessary continuous operation. This helps save energy and improve operational standardization. We also equip our systems with a standard RS485 communication interface that supports the MODBUS protocol for seamless integration with factory automation systems. This transforms the auto cooling system from a standalone unit into an integral part of large-scale digital manufacturing.

Choose the right cooling system for your production line!

The key to selecting the right auto cooling system for injection molding production is matching the chiller’s cooling method, reliability, and intelligent control to your factory’s needs. Our water-cooled and air-cooled chiller units offer practical options for different workshop conditions and process requirements. Featuring a modular structure, compressor protection, freeze protection, precise evaporator control, and an RS485 communication interface supporting the MODBUS protocol, they ensure long-term stable production. Air-cooled chillers are more suitable if the equipment requires easy mobility, no water pipe connections, and simple relocation. Water-cooled chiller units are more suitable if the equipment has a more comprehensive cooling infrastructure and requires higher heat dissipation efficiency.
