Freon Refrigeration

Freon is the trade name commonly used for a family of synthetic refrigerants, such as R22, R404A, R134a, and newer HFC/HFO blends. Freon-based systems are popular in small and medium-scale applications, including supermarkets, restaurants, cold rooms, and HVAC.

Why choose Freon?
  • Safer to handle, generally non-toxic and non-flammable.
  • Compact, reliable, and easier to install and maintain
  • Well-suited for modular cold rooms, retail outlets, and quick installations.
Points to consider:
  • Some Freon refrigerants (e.g., R22) are being phased out due to high GWP.
  • Slightly less efficient than ammonia for very large applications.
  • Environmental regulations may affect long-term availability of certain Freons.

Air-Cooled Condensing Units

Air-cooled condensing units are widely used in applications where water resources are limited or impractical. They rely on ambient air as the heat rejection medium, using finned condenser coils and high-performance fans to dissipate heat.

Product-benefits

Features of Rinac Air-Cooled Units

  • Pre-assembled with compressor, condenser, fans, valves, and controls
  • Stainless steel or powder-coated GI casing evaporators with auto-defrost
  • Microprocessor-based digital temperature controllers
  • Built-in safety features: high/low pressure switches, oil pressure switches, overload protection, phase protection
  • Optional liquid receiver, accumulator, oil separator, suction filter, and weatherproof housing

Technical Data

  • Medium Temperature: 2 kW – 400 kW
  • Low Temperature: 2 kW – 120 kW

Where they work best

  • Compact cold rooms
  • Retail outlets and supermarkets
  • Situations with limited water availability
  • Moderate climates

Water-Cooled Condensing Units

Water-cooled systems are chosen for their higher thermal efficiency, especially in warm climates where air cooling is less effective. These units use water as the heat rejection medium, typically through shell-and-tube or plate heat exchangers, supported by cooling towers for continuous circulation.

Product-benefits

Features of Rinac Water-Cooled Units

  • Hermetic or semi-hermetic compressors
  • Shell-and-tube or plate-type condensers for superior heat transfer
  • Stainless steel or powder-coated GI evaporators with auto-defrost
  • Water regulating valves for head pressure control
  • Advanced electrical control panels with overload and voltage protection
  • Microprocessor-based programmable digital temperature controller
  • Optional sight glass and suction filter for monitoring and protection

Technical Data

  • Medium Temperature: 2 kW – 400 kW
  • Low Temperature: 2 kW – 120 kW

Where they work best:

  • Large industrial plants
  • High-load cold storage facilities
  • Regions with stable water availability
  • Applications demanding maximum energy efficiency

Ammonia Refrigeration

Ammonia (NH₃) is one of the oldest and most efficient refrigerants used in industrial refrigeration. It is a natural refrigerant with zero ozone depletion potential (ODP) and zero global warming potential (GWP), making it one of the most environmentally sustainable choices available today.

Why choose Ammonia?
  • High thermodynamic efficiency → lower power consumption for large systems
  • Environmentally friendly → no contribution to climate change
  • Excellent for large-scale cold stores, ice plants, and food processing facilities
Points to consider
  • Ammonia is toxic and mildly flammable, requiring skilled handling and robust safety systems
  • Best suited for large industrial applications rather than small plug-and-play setups

Choosing the Right Combination

The choice between Ammonia vs. Freon and Air-cooled vs. Water-cooled depends on:

  • Scale of operation: Large-scale → Ammonia + water-cooled; small/medium → Freon + air-cooled
  • Environmental priorities: Sustainability → Ammonia; convenience → Freon
  • Utility availability: Water scarcity → air-cooled; abundant water → water-cooled
  • Temperature requirements: Very low storage temps → Ammonia; moderate temps → Freon
Advantages
  • Consultative approach — understanding each client’s requirements before recommending the best-fit refrigeration solution
  • Expertise in natural refrigerants like ammonia and synthetic options like Freon
  • Support for both air-cooled and water-cooled condensing systems
  • Decades of engineering experience focused on energy efficiency, safety, and sustainability
  • Refrigeration systems that preserve products and help businesses stay future-ready

Refrigeration is not just about cooling—it’s about choosing the right balance between performance, safety, cost, and environmental impact. With Ammonia and Freon-based systems, and options for both air-cooled and water-cooled condensers, Rinac provides end-to-end solutions that meet the evolving demands of industries across food, healthcare, retail, and beyond. Whether you are a supermarket in need of a reliable plug-and-play cold room or a large industrial processor looking for energy-efficient Ammonia plants, Rinac ensures dependable performance, innovative design, and lasting value.
