WE ARE COMMITTED TO NH₃ DIRECT EXPANSION AND LOW CHARGE SYSTEMS AS AN EFFICIENT AND SUSTAINABLE SOLUTION

We are committed to sustainability and energy efficiency through the design, development, and implementation of refrigeration systems using ammonia (NH₃) in direct expansion and low charge. This technology represents a natural evolution towards safer, more efficient, and environmentally friendly systems, aligning with decarbonization policies and the reduction of high-GWP refrigerants.

Benefits of Using NH₃ in Low-Charge Direct Expansion Systems
The use of ammonia (NH₃) as a refrigerant in low-charge direct expansion (DX) systems offers technical, economic, and environmental advantages, positioning it as a highly efficient and sustainable solution for industrial applications:

• Greater Environmental Sustainability
  NH₃ is a natural refrigerant, with global warming potential (GWP) equal to zero and no impact on the ozone layer (ODP = 0).
• Significant Reduction of Refrigerant Charge
  These systems use up to 30 times less NH₃ than a flooded system, reducing risk in case of leakage and simplifying regulatory compliance.
• Lower Operating Costs
  Lower refrigerant consumption and superior energy efficiency lead to significant savings in operation and maintenance.
• Annual Energy Savings
  Compared to HFC direct expansion systems, DX systems with NH₃ achieve higher energy efficiency, reducing annual electricity consumption.
• Optimized Heat Exchanger Design
  Less heat exchange surface is required in evaporators, thanks to ammonia’s excellent thermodynamic properties.
• Reduced Size of Refrigeration Piping
  Pipe diameters are smaller, simplifying installation and reducing material and insulation costs.
• No Need for a Dedicated Machine Room
  Thanks to the low charge, there is no obligation to provide a specific technical room, allowing the installation of packaged plants or chillers, offering flexibility and space savings.
• Simplified Regulatory Compliance
  The reduced refrigerant charge facilitates compliance with safety and environmental regulations, easing technical and legal restrictions.

1. Environmental Sustainability: NH₃ with GWP = 0 and ODP = 0.
2. Reduced Refrigerant Charge: Up to 30 times less NH₃ compared to flooded systems.
3. Lower Operating Cost: Savings in maintenance and refilling.
4. Lower Annual Energy Consumption: Higher efficiency than HFC DX systems.
5. Reduced Evaporator Surface: More compact heat exchangers.
6. Reduced Piping Diameters: Lower costs for installation and materials.
7. No Specific Machine Room Required: Greater design flexibility and less space.
8. Simplified Regulatory Compliance: Fewer restrictions, safer and more accessible designs.

These benefits make low-charge NH₃ direct expansion systems an efficient, safe, and sustainable solution for modern industrial facilities.
