At the Core of Industrial Refrigeration

Genesys™ Ammonia Systems

Ammonia has been a fundamental element of refrigeration since the early 1900s, particularly in cold storage and food processing facilities. Many of the foods we purchase, including fruits, vegetables, meats, and juices, owe their freshness to ammonia refrigeration systems. Ammonia stands out as one of the most cost-effective and energy-efficient refrigerants for low-temperature applications.

Key Advantages

Environmentally friendly

Ammonia is an eco-friendly refrigerant with zero ozone depletion potential (ODP) and a negligible impact on global warming.

Energy efficient

Ammonia-based refrigeration systems boast superior thermodynamic properties, resulting in efficient cooling and reduced energy consumption.

Expert design

Implementing ammonia refrigeration systems requires expertise and precision in design, ensuring optimal performance and safety.

Right for the Environment

With an ozone depletion potential (ODP) of 0 and a global warming potential (GWP) of 1, ammonia is future-proof selection that will not be phased out. Genesys™ Ammonia Systems are an environmentally responsible option for modern refrigeration end users. • ODP = 0 • GWP = 1

Efficient and Dependable

Ammonia is perfectly suited for large industrial applications due to its high efficiency, availability, and reliability. It is especially prevalent in chiller applications where the ammonia chills a secondary coolant. Components are readily available and robust, leading to dependable equipment and long lifespan. When the best ability is availability, Genesys™ Ammonia Systems are the best choice.

Low-Charge Ammonia Systems

Zero Zone is proud to bring high-quality, innovative refrigeration systems to our industrial customers.

  • Engineered ammonia package systems
  • Trouble-free operation
  • Energy efficient design

Recently, industrial refrigeration has trended toward low-charge ammonia systems. Minimizing the refrigerant charge enhances the safety of using ammonia while still being highly efficient.

Our ammonia systems can also be built inside a custom electrical/mechanical center (CEMC), which is a remote, packaged machine room. The CEMC is installed outside of the facility, making the ammonia system even safer for the end user.


Zero Zone offers a wide range of features for Genesys™ Ammonia Systems to suit your needs, which should be no surprise since we’ve always been green™.

  • Indoor, outdoor, or factory installed inside a custom electrical mechanical center (CEMC)
  • Capacity: 15 tons to 500 tons
  • Operating conditions: -50°F to 40°F
  • Reciprocating, scroll, or screw compressors
