If your business moves food, pharmaceuticals, flowers, or any temperature-sensitive product, the refrigeration unit in your delivery van is not an optional add-on. It is a regulatory requirement and a working asset that directly affects product safety, customer satisfaction, and your legal compliance.
This guide covers every stage: what van refrigeration is, the types of units available, how to choose the right one, what installation involves, what it costs, and how to keep the system running reliably.
What Van Refrigeration Does
A van refrigeration unit also called a transport refrigeration unit (TRU) cools the sealed cargo area of a delivery van to a controlled temperature during transit. It runs independently from the vehicle air conditioning system, which only cools the driver cab.
Under FSANZ Standard 3.2.2, chilled food must be transported at 5°C or below. Frozen food must be kept at -15°C or below. These are legal obligations for any food business moving product in Australia, not industry guidelines.
Types Of Van Refrigeration Units
Three main types are used in delivery vans across Australia. For a full breakdown of each, see our types of transport refrigeration units guide.
- Direct drive: The compressor is powered by the vehicle engine. The most common setup for metro delivery vans. Cooling stops when the engine stops.
- Electric standby: The unit plugs into 240V shore power when the van is parked. Cargo stays cold overnight without idling the engine.
- EV-compatible: Designed for electric vans. Draws from the vehicle high-voltage battery or an auxiliary battery system. No diesel required.
Key Specs to Check Before Choosing a Unit
Three specifications determine whether a unit will perform for your operation:
- Cargo volume (m³): The unit must be rated for the full insulated cargo space, not just the van’s listed load capacity.
- Temperature range: Confirm the unit reaches and holds your required setpoint. Frozen cargo needs -18°C to -25°C. Fresh produce typically needs 2°C to 4°C.
- Ambient rating: Australian summers regularly hit 38°C to 42°C in Melbourne. A unit must be rated for the high ambient temperatures your routes encounter.
Auto Frigo specifies units based on insulated cargo volume, the ambient temperature range for operating routes, and estimated door-open frequency. A unit undersized for the load will run continuously and still fail to hold temperature on a 40°C Melbourne day.
Direct Drive vs EV: Which Suits Your Van?
For most small to medium delivery vans on metro routes, a direct drive unit is the practical and cost-effective choice. The engine drives the compressor, installation is straightforward, and the units weigh less than self-powered alternatives.
Electric van refrigeration is a growing category. Daikin’s ZERO series is built specifically for zero-emission vehicles, drawing no diesel power. See our electric vehicle refrigeration guide for compatibility details.
What Installation Involves
Installing a van refrigeration unit involves more than attaching hardware to the roof. See our step-by-step conversion guide for the full process. In summary:
- Stripping the cargo area to bare metal
- Fitting insulation panels to the floor, walls, ceiling, and door (50mm for chilled, 75–100mm for frozen)
- Fitting a GRP or aluminium interior lining over the insulation
- Mounting the evaporator inside and the condenser unit on the roof or front wall exterior
- Running refrigerant lines and electrical connections
- Commissioning and testing to the required setpoint
All refrigerant handling must be performed by a technician licensed under the ARCtick scheme administered by the Australian Refrigeration Council. This is a legal requirement, not an optional credential.
What Van Refrigeration Costs
A standard chilled conversion for a small van starts from AUD $5,000 installed. Frozen conversions start from AUD $7,500. Multi-temperature dual-zone setups start from AUD $12,000. See the full van refrigeration cost guide for a detailed breakdown by van size, unit type, and configuration.
Maintaining Your Van Refrigeration Unit
A service every 6 months is the standard interval for transport refrigeration units in delivery vans. Key tasks include checking refrigerant levels, inspecting door seals, cleaning condenser coils, checking belt tension on direct drive units, and verifying the unit holds setpoint. See our full maintenance checklist for the complete schedule.

Frequently Asked Questions
Does a direct drive van unit stop cooling when I park the van and turn off the engine?
Yes. A direct drive unit draws power from the vehicle engine. When the engine stops, the compressor stops. If your cargo needs to stay cold during extended loading bay stops or overnight, you need a standby-capable unit or a self-powered unit. Auto Frigo can retrofit a standby connection to most existing direct drive installations.
How much weight does a refrigeration conversion add to my van?
A standard single-zone chilled conversion for a medium Sprinter-size van adds approximately 150–250kg, including insulation, lining, and the refrigeration unit. Frozen conversions with thicker panels add slightly more. Confirm your van’s payload capacity before specifying the conversion, especially if the vehicle carries heavy cargo.
Can I install van refrigeration on a leased vehicle?
Yes, but you need written approval from the lessor before any modifications. The conversion is a permanent structural change. Some lessors require the van to be returned to unmodified condition at end of lease, which means a removal and re-line cost. Confirm the terms before proceeding.
What maintenance does an ARCtick licence cover?
An ARCtick licence issued by the Australian Refrigeration Council authorises a technician to handle refrigerants, including topping up, recovering, and recharging refrigerant gas. Without this licence, a technician cannot legally touch the refrigerant circuit. Mechanical work on the unit that does not involve refrigerant does not require the licence.
How long does it take to get a van refrigeration unit installed in Melbourne?
A standard single-zone chilled conversion for a small to medium van takes 1–2 days at the Auto Frigo workshop. Frozen conversions take 2–3 days. Multi-temperature builds take 5–8 days. Allow 2 weeks’ lead time for scheduling, particularly between September and November when pre-summer demand increases across Melbourne.
