Applications of FIDEM FMACSGL Glycol Air Cooled Chillers
- FIDEM FMACSGL chillers are designed to handle sub-zero cooling using ethylene glycol or brine solutions, making them ideal for industrial and commercial processes that require low-temperature fluid cooling. Their modular design and wide operating range (-5°C to -30°C) make them suitable for a broad range of demanding applications.
1. Food and Beverage Industry
- Blast Freezing / Quick Freezing
- Rapid chilling of meat, seafood, baked goods, and ready-to-eat items.
- Fermentation Temperature Control
- Glycol loops help maintain stable temperatures in beer, wine, and dairy fermentation.
- Cold Room & Storage Cooling
- Maintains precise low temperatures in cold storage facilities.
2. Chemical and Pharmaceutical Processing
- Reactor and Vessel Cooling
- Temperature-sensitive mixing or reaction vessels requiring glycol circulation at -10°C to -30°C.
- Crystallization Processes
- Used in chemical synthesis, separation, and formulation processes.
- Solvent Condensation
- Maintains condenser coils below dew point to condense vapors safely.
3. Breweries and Distilleries
- Fermenter Cooling (Jacketed Tanks)
- Circulates chilled glycol around fermenters to control yeast activity.
- Bright Beer Tank and Serving Line Cooling
- Ensures beer is dispensed at the right temperature from tank to tap.
- Solvent Condensation
- Maintains condenser coils below dew point to condense vapors safely.
4. Plastic Industry
- Mold Temperature Control
- Stabilizes tool temperature in plastic injection molding at sub-zero levels.
- Extrusion Cooling
- Used for die-head or blown film air ring cooling with glycol/brine fluid.
5. HVAC and Building Systems
- Process Cooling in Industrial HVAC
- Glycol chillers act as primary chillers in extreme environments where water alone would freeze.
- Low-Temp Air Handling Units
- Supplies glycol to AHUs or fan coil units in pharmaceutical and food-grade cleanrooms.
6. Ice Rinks and Artificial Snow Systems
- Glycol chillers supply coolant loops for:
- Ice skating rink floors
- Ski slope snow machines
- Entertainment park winter simulations
7. Test Chambers & Environmental Simulation
- Used in temperature cycling chambers for electronics, battery, automotive and material testing under controlled sub-zero conditions.
8. Modular Industrial Installations
- Ideal for facilities requiring scalable chilling systems (multiple lines/processes).
- Redundancy through master/slave modular configuration ensures reliability.
Why Use Glycol Chillers?
Glycol prevents freezing in coolant lines, allowing operation below 0°C Reduces maintenance from ice build-up in pipes, tanks, and coils Provides stable and reliable cooling in extreme temperature environments
