How WA’s Extreme Heat Affects Transport Refrigeration, And What to Do About It

Why transport refrigeration services matter more in Western Australia than almost anywhere else on earth.

When you operate in Western Australia, heat isn’t just a seasonal nuisance — it’s a daily operational challenge. With temperatures frequently pushing past 40°C, refrigerated trucks, vans and trailers work significantly harder to maintain safe temperature control. This is exactly why transport refrigeration services are so critical for WA businesses. Without proper maintenance, diagnostics and servicing, your cooling equipment can struggle, break down or run inefficiently, creating the risk of stock loss, delivery delays and costly downtime.

TRACS has been supporting WA fleets for more than 20 years, helping commercial operators, food transport businesses, mining companies and logistics providers stay operational in one of the world’s harshest climates. In this blog, we break down exactly how extreme heat affects refrigeration units — and what you can do to prevent failures before they happen.

What Makes WA Heat So Hard on Transport Refrigeration?

Operating refrigeration equipment in Perth or regional WA is not the same as operating it in cooler parts of the country. WA’s environment puts additional strain on cooling systems, increasing the demand for reliable transport refrigeration services.

Key climate factors include:

• Long periods of 35–45°C temperatures

• Hot road surfaces radiating additional heat into the vehicle

• High UV exposure damaging hoses, seals and electronics

• Stop–start traffic in Perth reducing airflow across condenser coils

• Regional routes with long distances and no cool-down periods

Every one of these elements forces refrigeration units to work harder, consume more fuel and operate near capacity for long hours.

How Heat Affects Refrigerated Trucks and Trailers

To understand why proper transport refrigeration services are essential, it helps to know how heat impacts the components of a cooling system.

1. Reduced Cooling Efficiency

High ambient temperatures reduce the unit’s ability to reject heat, making it harder to maintain safe internal temperatures.

2. Higher Fuel Consumption

When the unit works harder, fuel usage increases significantly, affecting operating costs.

3. Increased Wear on Compressors and Engines

Operating at maximum load for long periods accelerates wear on critical components.

4. Temperature Fluctuations During Delivery

Hot conditions make it more difficult to hold steady temperatures, especially with frequent door openings.

5. Risk of Spoiled or Damaged Goods

Food, pharmaceuticals, flowers, seafood and sensitive goods are all affected quickly when temperatures rise even slightly.

This is exactly why fleet managers throughout Perth rely on TRACS for dependable transport refrigeration services that keep systems performing at their best.

Why Preventative Maintenance Is Essential in WA

In cooler climates, refrigeration units can sometimes get away with minimal servicing. In WA, this approach is risky.

Preventative maintenance helps you:

• Catch small issues before they become major breakdowns

• Maintain consistent temperature control

• Reduce fuel consumption

• Improve equipment lifespan

• Avoid costly roadside failures

• Stay compliant with cold chain requirements

TRACS technicians are trained to identify early signs of heat-driven wear, such as leaking seals, overheating compressors, blocked filters and electrical stress.

What You Can Do to Protect Your Refrigerated Fleet in WA

Besides professional servicing, there are practical steps operators can take to reduce heat-related issues.

1. Park in Shade When Possible

Shade prevents unnecessary heat soak before the unit starts up.

2. Pre-Cool the Trailer or Van

Lower internal temperature before loading goods, reducing system strain.

3. Reduce Door Opening Time

Repeated exposure to hot external air makes temperature recovery harder.

4. Use the Right Refrigeration System for WA Conditions

Carrier Transicold units, available through TRACS, are specifically engineered for harsh environments.

5. Schedule Regular Maintenance

Consistent servicing is the most effective way to minimise breakdowns.

When paired with high-quality transport refrigeration services, these simple practices dramatically improve performance.
