Collection: Commercial Blast Chiller

Commercial blast chillers (and blast freezers / shock freezers) cool cooked food rapidly through the 60–10°C danger zone, locking in moisture and meeting HACCP cooling standards. Hospitality Connect stocks blast chillers from Skope, Friginox, Polaris, Polar and FED in 3-tray bench through to 20-tray reach-in formats.

Types and capacity

• Bench blast chillers (3–5 tray): Slot under standard 900mm benches; 10–15kg cooling capacity per cycle.
• Reach-in blast chillers (10–14 tray GN 1/1): The standard for restaurant production kitchens; 25–40kg per cycle.
• Roll-in blast chillers (16–20 tray): Trolley-loading for production kitchens, central catering and aged-care; 60–100kg per cycle.
• Combi chillers / shock freezers: Dual-mode chiller and freezer; +90 to -18°C in a single cabinet.
• Probe-controlled cycles: Chill-by-core-temperature with fold-back probes — required for HACCP-defensible documentation.

Sizing for production

Blast chillers are sized by kg-per-90-minute cycle (HACCP standard cool: 60°C to 10°C in 90 minutes). A 3-tray bench unit cools 12kg of cooked product per cycle (3 hot GN 1/1 trays at 4kg each). Production restaurants commonly run two cycles back-to-back during dinner service for next-day prep. Multi-purpose units that also blast-freeze run a longer cycle (90 minutes to -18°C core); confirm if you need both modes before purchase.

Installation and operating notes

• Power and refrigerant: Bench units run 15A 240V; reach-in steps to three-phase. Most modern units use R290/R600a hydrocarbon refrigerant.
• Floor space and clearances: Reach-in units need 100mm rear ventilation; door swing requires 1100mm clear front for full 180° opening.
• Probe care: Insert probe into the centre of the largest item; clean and sanitise between cycles.
• Pack hot product loosely: Don't stack hot items — air must flow around each pan to chill on schedule.
• Defrost cycle: Auto-defrost runs after each cooling cycle; condensate drain must be clear.

Document blast-chiller cycles for HACCP audit. Australian Food Standards require cooling from 60°C to 21°C within 2 hours and 21°C to 5°C within a further 4 hours — total 6 hours from cook to chill. A correctly-sized blast chiller compresses that to 90 minutes for a HACCP-defensible record, with probe-data download for the council inspector. Don't overload — pack hot pans loosely with airflow space between them. Run the chiller continuously through service prep cycles; intermittent use stresses compressor cycles and shortens life. Schedule defrost and probe-clean as part of the daily checklist.

Why buy commercial blast chillers from Hospitality Connect

• Curated for Australian commercial kitchens: Every line is selected against the realities of AU service — voltage, room dimensions, council rules, ambient temperatures.
• Brand-direct relationships: We deal directly with manufacturers and importers, so you get current models and the right parts when you need them.
• Field-tested specs: Sizes, gauges and capacities listed on each product reflect what actually works in service, not glossy brochure numbers.
• Tech support that picks up: Pre and post-sale phone lines staffed by people who know commercial kitchens.
• Warranty handled here: We process the claim with the manufacturer; you keep cooking.

Commercial blast chillers care and longevity

• Inspect door gaskets fortnightly: A torn or compressed gasket forces the compressor to overrun and triples the energy bill.
• Clean condenser coils: Vacuum the front grille every two weeks. Greasy kitchens block coils within days and trip high-temp alarms.
• Don't block return-air paths: Stacked product against the back wall starves the evaporator and warms the load.
• Run a defrost cycle on schedule: Manual-defrost units need a planned cycle; auto-defrost still benefits from a quarterly deep service.
• Verify temperature with a calibrated probe: Onboard displays drift; check actual product core with a Hanna or Testo probe weekly.
• Plug into a dedicated circuit: Sharing a circuit with a dishwasher or induction hob causes nuisance trips and compressor wear.
