Chiller Selection FAQ
How do I choose the right industrial chiller?
Start with the application, cooling capacity, target temperature, flow rate, pump pressure, process fluid, ambient temperature, voltage, and installation conditions. The final chiller type should be confirmed by engineering review rather than horsepower alone.
What information is needed to select an industrial chiller?
Useful information includes application type, heat load or required cooling capacity, target outlet temperature, temperature stability, flow rate, pump pressure, process fluid, water quality, voltage, ambient temperature, installation space, and working hours.
Should I choose an air-cooled or water-cooled chiller?
Air-cooled chillers are easier to install where cooling tower water is not available. Water-cooled chillers are often suitable for larger heat loads, stable plant utilities, and continuous-duty projects.
Can I use horsepower alone to select a chiller?
No. Horsepower can be a rough reference, but final selection depends on real heat load, temperature difference, flow rate, pump pressure, ambient temperature, process fluid, and duty cycle.
Cooling Capacity & Engineering FAQ
How is chiller cooling capacity calculated?
Cooling capacity is usually estimated from heat load, flow rate, temperature difference, process heat input, or equipment data. For early review, the chiller selection tool or engineering checklist can help organize the required data.
What affects the real cooling capacity of a chiller?
Real cooling capacity can be affected by inlet and outlet water temperature, ambient temperature, condenser condition, water flow, refrigerant circuit, fouling, pump performance, and installation environment.
Why are pump flow and pump pressure important?
Cooling performance depends on enough chilled water reaching the heat source. Pipe length, height difference, filters, heat exchangers, and pressure loss can all affect the required pump flow and pressure.
What temperature stability can an industrial chiller provide?
Temperature stability depends on compressor control, tank volume, heat load variation, sensor position, flow rate, control logic, and project requirements. APT can review the required stability during quotation.
Air-Cooled vs Water-Cooled FAQ
What is the difference between air-cooled and water-cooled chillers?
Air-cooled chillers reject heat to ambient air through condenser fans. Water-cooled chillers reject heat through condenser water and usually require a cooling tower or plant cooling water system.
When should I choose an air-cooled chiller?
Choose an air-cooled chiller when the site has enough ventilation, cooling tower water is not available, installation should be simple, or the project needs a self-contained cooling system.
When should I choose a water-cooled chiller?
Choose a water-cooled chiller when the project has stable condenser water, larger cooling capacity, indoor installation needs, or continuous-duty cooling requirements where condenser water is practical.
Do air-cooled chillers need good ventilation?
Yes. Air-cooled chillers need enough airflow and service clearance around the condenser. Poor ventilation can reduce cooling capacity and may cause high pressure alarms.
Custom Chiller FAQ
When is a custom industrial chiller required?
A custom chiller is recommended when standard models cannot meet the required voltage, pump pressure, tank size, heat exchanger material, high ambient condition, corrosion resistance, stainless steel configuration, control logic, or layout requirement.
Can APT customize voltage, pump, tank, and heat exchanger?
Yes. APT can review custom voltage, pump flow, pump pressure, tank volume, heat exchanger material, control logic, refrigerant, cabinet layout, and export requirements by project.
Can APT design chillers for high ambient temperature?
Yes. High ambient projects can be reviewed by condenser margin, fan configuration, refrigerant selection, cabinet ventilation, protection logic, and outdoor or hot-climate installation conditions.
Can APT review corrosion-resistant or stainless steel chiller requirements?
Yes. APT can review stainless steel, titanium, secondary loop, and corrosion-resistant configurations according to water quality, chemical medium, pH, chloride level, and heat exchanger compatibility.
Application Cooling FAQ
What applications use industrial chillers?
Industrial chillers are used for thermal spray, laser systems, injection molding, electroplating, die casting, chemical processing, CNC machining, food-grade process cooling, laboratory equipment, and other process cooling applications.
What type of chiller is used for thermal spray cooling?
Thermal spray and HVOF systems often require robust industrial process chillers with sufficient cooling capacity, flow rate, pump pressure, and continuous-duty reliability for spray gun, torch, and auxiliary equipment cooling.
What type of chiller is used for laser cooling?
Laser systems often use compact air-cooled chillers or precision process chillers to cool laser sources, optics, cutting heads, welding heads, and closed-loop water circuits.
What type of chiller is used for injection molding or die casting cooling?
Injection molding and die casting projects may use air-cooled or water-cooled process chillers depending on mold heat load, hydraulic oil cooling, machine size, flow rate, pump pressure, and workshop conditions.
What should be considered for electroplating or chemical cooling?
Electroplating and chemical cooling require review of bath chemistry, corrosion risk, heat exchanger material, secondary loop design, tank volume, target temperature, and safety conditions.
Technical Documents & Downloads FAQ
Can I download catalogs and datasheets?
Yes. APT provides technical downloads such as product catalogs, datasheets, selection guides, maintenance checklists, manuals, and application PDFs for preliminary project review.
Can I request a specific datasheet or manual?
Yes. If the required datasheet, manual, certificate, or application PDF is not listed, you can contact APT with model or project information and request the latest available document.
Are downloaded files enough for final model selection?
Downloaded files are useful for preliminary comparison, but final model selection should be confirmed by APT engineers according to actual heat load, temperature, flow, pump pressure, voltage, and installation conditions.
Can APT provide case study PDFs?
Yes. Application case PDFs may be available through the downloads page or by request. APT can also provide project-specific technical replies when enough process data is available.
Installation, Maintenance & Troubleshooting FAQ
What should be prepared before installing a chiller?
Prepare installation space, airflow clearance, water piping, electrical supply, drainage, foundation, ambient conditions, water quality, process connection, and access for maintenance.
How often should an industrial chiller be maintained?
Maintenance frequency depends on operating hours, water quality, dust level, condenser condition, ambient environment, and process duty. Regular cleaning, inspection, and water-side maintenance are important.
What causes high pressure or low pressure alarms?
High pressure alarms may be caused by poor condenser cooling, high ambient temperature, blocked airflow, dirty condenser, or water-side issues. Low pressure alarms may relate to refrigerant circuit condition, low load, flow issues, or protection settings.
How can water quality affect chiller performance?
Poor water quality can cause scaling, corrosion, blocked filters, reduced heat transfer, pump wear, and heat exchanger damage. Clean water and regular filter maintenance help improve reliability.
What after-sales support can APT provide?
APT can provide technical communication, manuals, spare parts support, troubleshooting guidance, replacement parts, and project-specific service support according to the chiller model and order conditions.
