What Is an Air-Cooled Industrial Chiller?Product Overview
An air-cooled industrial chiller uses a compressor and an air-cooled condenser to lower the temperature of circulating cooling water and deliver it steadily to production equipment, with no cooling tower required. Plastic processing needs precise temperature control at every stage, from material melting and molding through to cooling and solidification. Unstable water temperature can cause dimensional variation, surface defects or shorter mold life, which makes a stable supply of cooling water one of the foundations of process quality.
How an Air-Cooled Chiller WorksHow It Works
- 1 Compression The compressor pressurizes low-pressure refrigerant gas into a high-temperature, high-pressure gas.
- 2 Condensation (air-cooled heat rejection) The air-cooled condenser rejects heat with fans; the refrigerant releases heat and condenses into liquid — which is why no cooling tower is needed.
- 3 Expansion The refrigerant passes through the expansion device, dropping in pressure and temperature so it is ready to absorb heat.
- 4 Evaporation (chilled water cooling) In the evaporator the refrigerant absorbs heat from the circulating water; the chilled water reaches the set temperature (±1°C) and is supplied to the process equipment.
Applicable ProcessesApplications
Extrusion
Supplies the continuous cooling water required by extrusion dies and cooling or sizing sections.
Blow Molding
Helps molds and products cool and set quickly, keeping production cycles stable.
Rubber Processing
Controls temperature rise during processing to maintain material properties and process stability.
PET Processing
Supports the cooling water temperature and flow that PET molding processes require.
Core BenefitsWhy AT-B Series
The AT-B Series balances temperature control accuracy, production efficiency and long-term operating cost to keep production lines running steadily.
Precise Temperature Control
Outlet temperature is held within ±1°C, supporting stable process quality.
Higher Production Efficiency
A stable cooling water supply helps shorten molding cycles and reduces downtime and defects caused by temperature fluctuations.
Energy Saving
Saves approximately 20% energy compared with conventional models, lowering long-term electricity cost.
Stable and Reliable
Multiple safety protections reduce the risk of equipment damage under abnormal conditions.
Flexible Configuration
A range of models covers different cooling capacities, so selection can match the scale of your production line.

How to Choose Between Air-Cooled and Water-Cooled Chillers
| Comparison | Water-cooled chiller | Air-cooled chiller (AT-B Series) |
|---|---|---|
| Cooling tower | Requires a separate tower and piping | Not required; fans reject heat directly |
| Installation | Needs a cooling tower, cooling water piping and a circulation pump | Position the unit, connect power and chilled water piping — simpler installation |
| Water cost | Evaporation from the tower requires continuous make-up water | No cooling water consumption |
| Routine maintenance | Tower cleaning, water quality and algae management | Periodic cleaning of the condenser fins |
| Best suited to | Plants with a large cooling load and a centralized cooling room | Lines with limited space, no cooling tower option, or a need to cut water use |

Frequently Asked QuestionsFAQ
What processes is the AT-B Series suitable for?
It suits production lines that need a stable supply of cooling water, including plastic injection molding, extrusion, blow molding, rubber processing and PET processes. Actual implementation should still be confirmed against line load and layout.
How should I choose between AT-60B, AT-80B and AT-120B?
Selection is based mainly on the required cooling capacity (kW), power frequency (50/60Hz) and on-site water piping layout. Share your current equipment quantity, cooling load per machine and line layout, and the COLDER sales team will help evaluate.
Are the specifications of the machines on display the same as the catalog?
No. The machines on display use an enhanced configuration (800 L main water tank, 360 L auxiliary tank, SUS304 full stainless steel piping and more), which differs from the standard catalog specifications. Actual specifications are subject to formal quotation and technical confirmation.
What is the difference between air-cooled and water-cooled chillers?
Air-cooled chillers need no cooling tower and no additional circulating water source, so installation and maintenance are simpler. They suit sites without space for a tower or users looking to cut water cost. Suitability should still be assessed against on-site conditions.
What should I prepare before visiting the booth?
Bring your existing equipment quantity and cooling load, target outlet water temperature, site power specification and water piping layout, plus expected output. The more complete the information, the faster we can recommend a model and configuration.
