High-Efficiency Ammonia Instant Glycol Chillers by Alfachill Projects

What is an Ammonia Instant Glycol Chiller?

An Ammonia Instant Glycol Chiller is an industrial refrigeration system that uses ammonia as the primary refrigerant to rapidly cool a glycol-water solution through a Plate Heat Exchanger (PHE). The chilled glycol is then circulated to various process equipment, storage tanks, air handling units, or production lines where indirect cooling is required.

Unlike direct ammonia systems, glycol acts as the secondary heat transfer fluid, carrying cooling energy throughout the plant while significantly reducing the amount of ammonia circulating in occupied production areas. This makes the system an ideal solution for industries seeking high refrigeration efficiency with enhanced operational safety.

How an Ammonia Instant Glycol Chiller Works

The system operates on the proven vapor compression refrigeration cycle, combined with an indirect glycol cooling loop.

• Step 1: Ammonia Compression : Low-pressure ammonia vapor is compressed by a high-efficiency screw or reciprocating compressor, increasing its pressure and temperature.
• Step 2: Heat Rejection : The high-pressure ammonia vapor passes through the condenser, where heat is rejected to the atmosphere or cooling water, converting the refrigerant into liquid ammonia.
• Step 3: Expansion : Liquid ammonia flows through an expansion valve, reducing its pressure and temperature before entering the Plate Heat Exchanger.
• Step 4: Instant Glycol Cooling : Inside the Plate Heat Exchanger, the cold ammonia absorbs heat from the circulating glycol solution, rapidly reducing the glycol temperature to the desired level.
• Step 5: Process Cooling : The chilled glycol is pumped through insulated pipelines to process equipment such as milk coolers, fermentation tanks, ice cream aging tanks, jacketed vessels, air handling units, and other cooling applications. After absorbing heat from the process, the warmer glycol returns to the chiller, where it is cooled again, creating a continuous closed-loop cooling cycle.

This indirect cooling method provides precise temperature control while minimizing ammonia circulation outside the refrigeration plant.

Advantages of Ammonia Instant Glycol Chillers

• Rapid Cooling Performance : The Plate Heat Exchanger provides fast heat transfer, allowing glycol to reach the desired process temperature within a short time.
• Improved Safety : Only a limited quantity of ammonia remains inside the refrigeration plant, while glycol circulates throughout the production facility, reducing ammonia exposure in occupied areas.
• Excellent Energy Efficiency : Ammonia offers superior thermodynamic properties, resulting in lower electricity consumption and reduced operating costs.
• Consistent Process Temperatures : The system delivers stable glycol temperatures, ensuring consistent product quality across all production processes.
• Reduced Operating Costs : Lower power consumption, efficient heat transfer, and optimized refrigeration design help reduce lifecycle costs.
• Environmentally Friendly : Ammonia is a natural refrigerant with:
  • Zero Ozone Depletion Potential (ODP)
  • Zero Global Warming Potential (GWP)
  making it one of the most sustainable refrigeration solutions available.
• Flexible Cooling Distribution : A single glycol chiller can supply chilled glycol to multiple process areas simultaneously, improving plant flexibility and efficiency.
