Natural Refrigeration Solutions

In the face of climate change and environmental challenges, the refrigeration industry is rapidly shifting its focus towards eco-friendly alternatives known as Natural Refrigeration Solutions. These innovative cooling technologies harness the power of nature to create a more sustainable and environmentally responsible approach to refrigeration. By replacing harmful synthetic refrigerants with natural substances, these solutions play a pivotal role in reducing greenhouse gas emissions and preserving the delicate balance of our planet's ecosystem.


Carbon dioxide (CO2) and ammonia (NH3) have been present in our environment since time immemorial, and their role in refrigeration dates back to the 1800s. Over the years, these natural substances have found significant applications as refrigerants. Today, natural refrigerants are gaining popularity as viable options for both retail and industrial refrigeration solutions.




CO2 and NH3 are the gold standard for ozone depletion potential (ODP) and global warming potential (GWP). Neither are ozone depleting (0). CO2 has a GWP of 1—which is because it is used as the baseline for that scale—and NH3 has a GWP of 0.

CO2 is nonflammable and nontoxic, and it is a low-cost refrigerant. The recent advent of high-pressure, iron-impregnated copper has allowed the traditionally stainless-steel piping to transition to familiar brazed copper piping, further improving value and simplifying repairs.

NH3 is energy- efficient and cost-effective and used in Industrial applications.

Benefits of Natural Refrigeration Solutions

Reduced Environmental Impact

Natural refrigerants have minimal GWPs and no ODP, resulting in significantly lower contributions to global warming and ozone depletion. By adopting these solutions, businesses and industries can play a crucial role in combating climate change and protecting the planet for future generations.

Regulatory Compliance

Many countries are phasing out the use of high-GWP synthetic refrigerants, and stricter environmental regulations are being enforced. Embracing natural refrigeration solutions ensures compliance with these evolving regulations, avoiding penalties and legal complications.

Energy Efficiency

Natural refrigerants often exhibit superior thermodynamic properties, resulting in enhanced energy efficiency and lower operating costs for refrigeration systems. This not only benefits the environment but also provides businesses with cost savings in the long run.

Improved Reputation and Consumer Appeal

As environmental consciousness grows among consumers, businesses that adopt sustainable practices, including natural refrigeration solutions, gain a competitive edge and attract eco-conscious consumers.
