Energy Comparison
For the most accurate results, compare models with similar specifications such as volume and door design. Adjust the energy cost per kW to better reflect your actual costs and potential savings.
What is GEMS?
GEMS (Greenhouse & Energy Minimum Standards) is the regulatory framework for energy efficiency and environmental performance across a wide range of products in Australia and New Zealand, including commercial refrigeration. It was established under the GEMS Act 2012 and is administered by the Equipment Energy Efficiency (E3) program, a joint initiative between the two countries. Each country has its own regulator responsible for testing and compliance.
- GEMS applies to manufactured, imported, and retailed products.
- Not all refrigeration units are covered. For example, pizza prep benches and ingredient fridges may not be tested under GEMS 2020.
- Approved products can be found in the public GEMS database. If a unit is not listed, it does not meet GEMS 2020 standards.
Cabinet Classification – What to Look For
GEMS classifies refrigeration cabinets by Climate Class and M Pack Temperature. This helps determine their suitability for food and beverage storage or display.
1. Climate Class (Testing Conditions)
| Class | Use Type | Conditions |
|---|---|---|
| 3 | Display, Storage | 25°C ambient, 60% humidity |
| 4 | Storage | 30°C ambient, 55% humidity |
| 5 | Storage | 40°C ambient, 40% humidity |
Note: Display cabinets are tested only in Class 3. Storage cabinets are tested across all classes.
2. M Pack Temperature (Internal Temperature Range)
| Code | Type | Temp Range | Suitable For |
|---|---|---|---|
| M1 | Fridge | -1°C to +5°C | Perishables (Food Safe) |
| M2 | Fridge | -1°C to +7°C | Non-perishables |
| L1 | Freezer | Below -18°C to -15°C | Perishables |
| L2 | Freezer | Below -18°C to -12°C | Non-perishables |
| H1 | Fridge | +1°C to +10°C | Not for commercial use |
| H2 | Fridge | -1°C to +10°C | Not for commercial use |
