Hotels & Venues (Australia): Choosing Class 4/5 Display Fridges for Holiday Peak — Climate Class, Door‑Open Stability & GEMS 2024 (EEI)
Search intent: commercial investigation. Bar managers, venue operators and hotel engineering teams use this guide to pick display fridges that stay cold on the top shelf during peak, meet Australian FSANZ temperature expectations, and comply with the GEMS 2024 program.
- Choose by climate class: Class 4 (~30 °C/55% RH) fits most Australian bar/front‑of‑house; heavy‑duty validation at Class 5 (~40 °C/40% RH) is for hot installs or constant door‑opens.[1]
- From 5 Oct 2024, refrigerated cabinets must be registered under GEMS 2024 and assessed via EEI. Ask every supplier for the registration ID and the EEI figure.[2]
- FSANZ expects PHF kept at ≤ 5 °C (cold‑holding) or ≥ 60 °C (hot‑holding). If items leave control, use the 2‑hour/4‑hour rule and log times.[3] [4]
- Ventilation is non‑negotiable: observe the manual’s rear/side/top clearances, avoid sun/heat plumes, and probe product on the warmest shelf (top/front).
Who this is for (and what success looks like)
- Bar manager — wants ice‑cold drinks at rush, stable top‑shelf temps, and a layout that sells water first.
- Hotel engineering — wants equipment that survives summer ambients, with clear install/ventilation boundaries and predictable energy use.
- Procurement — wants copy‑ready RFQ lines (EEI, climate class, heavy‑duty validation, registration ID, refrigerant & GWP).
Why bars warm up at exactly the wrong moment
Peak service adds simultaneous heat loads: door‑open cycles, warm restocks and back‑pressure from coffee machines or under‑bar appliances. A light‑duty (Class 3) cabinet in a hot, cramped bay will struggle to keep the top shelf at ≤ 5 °C. Matching climate class to your install conditions and enforcing ventilation rules prevents most “warm drink” complaints.
Climate class explained (and how to choose)
| Climate class | Test room (typical) | Where it fits in venues | What to ask suppliers |
|---|---|---|---|
| Class 3 | ~25 °C / 60% RH | Cool back rooms; limited browsing | EEI & kWh/24 h at Class 3; GEMS registration ID |
| Class 4 | ~30 °C / 55% RH | Most Australian front‑of‑house bars and kiosks | EEI at Class 4; shelf‑temp stability under door‑open cycles[1] |
| Heavy‑duty validation (Class 5) | ~40 °C / 40% RH | Event bars, hot kitchens, sun‑exposed or cramped line‑ups | Manufacturer evidence of Class 5 validation (heavy‑duty)[1] |
GEMS 2024 (EEI) — what changed and how to audit quotes in 60 seconds
Australia’s refrigerated cabinets are regulated under GEMS 2024. From 5 October 2024, supply requires registration, and efficiency is assessed with EEI (Energy Efficiency Index). Before approving a purchase, request the model’s GEMS registration ID, EEI and the declared climate class for tests.[2]
Registration checklist
- GEMS registration ID provided on quote/spec.
- EEI value and the test climate class are declared.
- Product category matches your use (display, drink merchandiser, storage, scooping).[2]
If you don’t check
Unregistered or mis‑classified supply risks enforcement action, weakens your energy/business case and undermines audit confidence.
Ventilation & placement — the quiet killer of bar performance
10‑point pass/fail for installers
- Rear/side/top clearances per manual (no boxing‑in of grilles).
- No direct sun; fit a modest deflector if near western glazing.
- Don’t nestle next to coffee machines or dishwashers’ exhausts.
- Provide a cool air path in and a free heat path out; avoid recirculation.
- Power supply on a clean circuit; avoid nuisance trips at peak.
- Level the cabinet; confirm door self‑close works with full load‑out.
- Night blinds used after service on open display merchandisers.
- Monthly coil clean and quarterly seal inspection scheduled.
- Probe product temps on top/front shelves during service.
- Keep restock crates away from evaporators and air curtains.
Front‑of‑house product mix that stays cold
- Place water at eye‑level in a Class 4/5 cabinet to reduce “door linger”.
- Rotate warm restocks to lower/middle shelves; don’t bury the air outlets.
- Use double‑door models for split traffic (bartender vs. self‑serve).
Running‑cost maths (so finance signs off the upgrade)
Compare like‑for‑like duty and climate class. Then run the simple cost formula:
kWh per 24 h × tariff ($/kWh) × 365Example A — bar merchandiser
3.8 kWh/24 h at Class 4, tariff $0.30/kWh → ≈ 3.8 × 0.30 × 365 = $416.10/year.
Example B — heavy‑duty validated replacement
3.1 kWh/24 h at Class 4 → ≈ 3.1 × 0.30 × 365 = $339.15/year. Saving ≈ $76.95 per cabinet per year; scale by lineup.
Copy‑ready RFQ clauses (paste these into your tender)
| # | Specification line | Why it matters |
|---|---|---|
| 1 | Cabinet is registered under GEMS (Refrigerated Cabinets) Determination 2024; supplier to provide registration ID and EEI. | Registration is mandatory before supply; EEI enables fair comparison.[2] |
| 2 | Declare test climate class and provide heavy‑duty (Class 5) validation where site heat/door‑opens demand it. | Matches performance to real bar conditions.[1] |
| 3 | State kWh/24 h at the declared class and any energy modes (e.g., night blinds). | Lets finance verify running‑cost claims. |
| 4 | List installation clearances, ventilation path and ambient operating limits; attach commissioning checklist. | Prevents warm‑shelf complaints and nuisance faults. |
| 5 | Specify refrigerant and GWP; prefer low‑GWP (e.g., R290) where suitable. | Aligns with sustainability expectations.[5] [6] |
Two decision tables you’ll actually use
Climate‑class chooser for bars & venues
| Your reality | Recommended class | Why | What to verify |
|---|---|---|---|
| Cool back‑bar room; low door‑opens | Class 3 | Light duty; easy ≤ 5 °C | EEI & kWh/24 h at Class 3; registration ID |
| Busy front‑bar ~30 °C; browsing customers | Class 4 | Closer to service reality | EEI at Class 4; door‑open stability data[1] |
| Event bar, sun or hot kitchen; cramped install | Heavy‑duty validated (Class 5) | Stress‑tested at ~40 °C/40% RH | Manufacturer evidence of Class 5 validation[1] |
Service‑day temperature control (post this near the pass)
| Control | Your target | Action if exceeded | Authority |
|---|---|---|---|
| Cold‑holding (display) | ≤ 5 °C (PHF) | Return to ≤ 5 °C or apply time control | FSANZ |
| Time as a control | 0–2 h use/refrigerate; 2–4 h use; > 4 h discard | Discard > 4 h cumulative | FSANZ |
Case study: “Three hot bars, one heavy‑duty fix”
A CBD hotel runs two lobby bars and one rooftop event bar. Complaints spike on 35 °C days; top shelves read 7–9 °C during pre‑dinner rush; fridges sit inside tight millwork near coffee machines.
Problems
- Light‑duty (Class 3) cabinets boxed‑in; poor heat exhaust path.
- Warm restocks placed on top shelves; no night‑blind habit.
- No proof of registration/EEI; quotes mixed climate‑class claims.
Fix
- Upgrade to Class 4 with heavy‑duty validation for rooftop; cut rear panels to restore ventilation, add discreet deflectors.
- Restock to lower shelves; institute night‑blind routine and monthly coil cleaning.
- Procurement now requests GEMS registration ID, EEI and declared test class on every quote.[2]
Outcome (method‑based)
- Top‑shelf probes hold ≤ 5 °C through rush; complaints drop.
- Energy per cabinet falls by ~0.5–0.7 kWh/24 h depending on model/class.
- Install faults down; fewer nuisance trips; cleaner audits.
Use your own tariff and model kWh/24 h to calculate exact savings.

FAQ — straight answers for bars & venues
1) Why are Class 4 and Class 5 on my quotes?
They describe test‑room conditions used for performance/energy. Class 4 (~30 °C/55% RH) suits most Aussie service areas; heavy‑duty validation at Class 5 (~40 °C/40% RH) proves stability in harsher conditions.[1]
2) Do I have to buy “registered” cabinets?
Yes. Under GEMS 2024, relevant refrigerated cabinets must be registered before supply and declare EEI. Ask for the registration ID on every quote.[2]
3) What temperature should my display hold?
For potentially hazardous food (PHF), hold at ≤ 5 °C; if items leave control during service, apply the 2‑hour/4‑hour rule and log times.[3] [4]
4) Will a heavy‑duty cabinet cost more to run?
Not necessarily — modern heavy‑duty‑validated models can have competitive (even lower) EEI for their duty. Compare kWh/24 h at the same class and factor night‑blind usage.
5) What about refrigerants?
Where suitable, prefer low‑GWP options such as R290 (propane). Australia references IPCC AR4 GWPs in policy reporting.[5] [6]
