| Freon |
Ammonia (NH3) |
| Ideal for single ice maker applications with low volume output |
Ideal for high capacity ice production requiring multiple ice makers as small applications are typically too complex |
| Applies to HFO (C3H2F4) refrigerant only - Environmentally safe as HFO meets refrigerant regulations of low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP)
|
Environmentally safe with zero Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP)
|
| Generally cheaper to install than ammonia systems as Commercial Refrigeration Contractors are more readily available
|
Less expensive to purchase and more efficient by 10% or more using less electricity than other systems with a higher heat transfer co-efficient
|
| Process Safety Management (PSM) regulations are not required as it is non-toxic
|
Distinct pungent odor allows for immediate detectability of leaks
|
| Cons
|
Cons
|
| Odorless making it hard to detect leaks and can cause asphyxiation at high levels
|
Requires safety/management procedures (PSM) as the product is flammable and can cause asphyxiation at high levels
|
| Not efficient for large applications
