High Temperature Workshop Industrial Chiller Unit Selection Guide: A Pitfall Avoidance Guide for Chemical Injection Cooling Equipment

Industrial workshops in chemical, new material, and chemical synthesis sectors maintain a high-temperature environment for long periods. The continuous heat dissipation of production equipment requires a stable chiller unit to remove heat. Ordinary small-sized refrigeration equipment has insufficient heat dissipation capacity and is prone to water temperature not dropping enough, resulting in high-pressure shutdown of the unit and direct interruption of production line processing. This article, based on the industrial high-temperature workshop conditions, outlines the core points for chiller unit selection.
1. Special Requirements for Chiller Units in High-Temperature Workshops
The environmental temperature in the workshop is always above 35℃, and the heat dissipation load of the chiller unit's condenser increases significantly. It is necessary to increase the heat exchange area and equip large-power cooling fans; the production line operates 24 hours continuously, so compressors and water pumps should be selected with heavy-duty and durable models to reduce the failure rate during continuous operation; some chemical workshops have corrosive volatile gases, so the chiller unit's shell and pipelines should be protected with anti-corrosion coatings; in injection molding workshops, the water quality contains many impurities, so the water path of the chiller unit should be equipped with filtering components to avoid pipe blockage.
Civilian small-sized chiller units are only suitable for normal-temperature indoor environments and lack special optimization for high-temperature, heavy-load, and anti-corrosion. After being used in industrial high-temperature workshops for 1-3 months, they will frequently malfunction, affecting the continuous operation of the production line.
2. Key Parameters for Calculating Chiller Unit Cooling Capacity
When selecting a chiller unit, it is necessary to collect the number of injection molding machines, the heat generation of each machine, the highest environmental temperature of the workshop, the target chilled water outlet temperature, and the length of the water circulation pipeline. Estimating power only based on the number of machines will result in a chiller unit with insufficient cooling capacity and failure to meet the cooling requirements. The impact of the deviation in calculation will be more significant as the production line capacity increases.
Technical personnel from the source factory can accurately calculate and match the chiller unit power based on on-site data, avoiding energy waste caused by excessive power or inability to meet the cooling requirements due to insufficient power.
3. Differentiation of Chiller Unit Adaptation in High-Temperature Workshops
For areas with water shortage, good ventilation conditions in the workshop, and medium-power cooling requirements, choose a wind-cooled industrial chiller unit, which does not require a water tower and is easy to install; for large-scale production workshops with high-power continuous cooling, sufficient water supply, poor ventilation, and large cooling requirements, choose a water-cooled chiller unit. The high-load operation ensures more stable heat dissipation and lower long-term operating energy consumption.
For coastal and highly corrosive workshops, prioritize the use of wind-cooled corrosion-resistant upgraded models to reduce the maintenance workload caused by corrosion and blockage of water circulation pipelines.
4. Equipment and Service for Industrial High-Temperature Scenarios
Shaoxing Xueying Refrigeration can customize industrial chiller units based on the heat-generating equipment and environmental temperature in the workshop, increasing the heat exchange structure of the condenser to adapt to high-temperature heat dissipation, upgrading anti-corrosion pipelines for chemical scenarios, and providing water circulation filtering components. Enterprises can complete the calculation of the working conditions on-site, issue an exclusive cooling plan, and support domestic industrial plants and export customizations for injection molding and chemical factories. The entire machine is completed with a high-temperature continuous load simulation test upon factory delivery.
5. Maintenance and Fault Reduction Techniques for Industrial Chiller Units
Clean the condenser and water path filters monthly to ensure smooth heat dissipation and water circulation; during the high-temperature summer period, check the operation status of the fan in advance to avoid high-pressure alarms caused by fan failure; replace the circulating water filter consumables annually and inspect the sealing points of the pipeline to prevent water leakage that affects production. Summary
In high-temperature industrial workshops, the air conditioning units must be equipped with heavy-load, high-temperature-resistant, and anti-corrosion special configurations. Accurately calculating the cooling capacity is the core of the selection process. Based on the water supply and ventilation conditions of the factory area, choose either air-cooled or water-cooled models, and combine with the professional working condition calculation plan from the source factory to ensure the long-term stable cooling of the production line and reduce downtime losses.
