Air Cooled Air Chiller
General Description:
FIDEM FMACA Series Air Cooled Air Chillers are high-performance, compact units specifically designed to deliver consistent cooled air for processes like blown film extrusion lines. Unlike water chillers requiring secondary heat exchangers, FMACA models use direct expansion of refrigerant, enhancing energy savings and reducing system footprint.

FIDEM Chiller Applications Guide
1. Air Cooled Air Chillers (FMACA Series)
- Precise temperature control independent of ambient
- Rapid air cooling for better process quality
- Energy efficient operation in tropical climates
- Easy maintenance & long service life
- Proven performance in plastics and film industry
Applications:
- Blown Film Extrusion Lines
- To provide cooled process air directly to the air ring or IBC system—critical for maintaining film thickness and bubble stability.
- Plastic Processing Equipment
- Supplies controlled temperature air to machines needing ambient-independent cooling.
- Electronics Manufacturing
- Used in clean rooms or enclosed spaces where process air must remain cool and moisture-free.
- Industrial Drying Applications
- Ensures consistent low-temperature air for drying operations in packaging, pharmaceuticals, and printing.
- HVAC Ducted Air Cooling Systems
- In small-to-medium factories needing precise ambient or process air temperature regulation.
Advantages:
- Easy to install (no cooling tower or piping needed)
- Lower maintenance than water-cooled chillers
- Best suited for areas with space for open-air heat rejection
- Ideal for small- to medium-scale cooling loads
2. Water Cooled Air Chillers (FMACW Series)
Applications:
- High-Speed Blown Film Plants
- Where large volumes of cooled air are needed with tight temperature control, irrespective of outdoor temperatures.
- Clean Room Air Cooling
- For applications needing stable air conditions and low noise, e.g., electronics, pharma, medical molding.
- Process Air Cooling for Industrial Equipment
- Used where ambient temperatures are very high, and air-cooled systems become less efficient.
- Film Extrusion in Harsh Climates
- In hot, dusty or humid regions where air cooled condenser performance degrades.
- Retrofit Applications
- Where cooling towers already exist on-site and water resources are economical.
Advantages:
- Better energy efficiency in large plants
- Lower noise since condenser is water-cooled
- Compact in size—can be installed indoors
- Performance is independent of ambient air temperature
- Perfect for high-capacity operations or continuous duty cycles
Summary Comparison:
- Feature FMACA (Air Cooled) FMACW (Water Cooled)
- Heat Rejection To ambient via fans To water via cooling tower
- Cooling Capacity Range 9 TR to 30 TR 8 TR to 45 TR
- Installation Location Outdoor or semi-indoor Indoor (requires cooling tower)
- Initial Cost Lower Higher (cooling tower needed)
- Efficiency (High Ambient) Drops with high ambient Maintains performance
- Maintenance Less frequent Needs regular tower water checks
- Footprint Slightly larger More compact
- Ideal For Simple, moderate-duty jobs High-precision, large-duty applications
