Your fermentation tanks are brimming, the fruit is just right, but your glycol chiller is working overtime and still struggling to keep things cool. This is the moment when under-capacity can threaten to derail all the hard work you’ve put into your vineyard.

In our last blog, The Hidden Risk of Under-Capacity in Winery Cooling, we discussed how a bumper crop or an unexpected heatwave can push a winery’s cooling system to its breaking point. So, what’s the best way to boost capacity exactly when you need it — without breaking the bank?

Case Study in Action: Winery Rental Chiller Success

When a North-West Victoria winery faced a bumper fruit season and unseasonal summer heat, its existing refrigeration system couldn’t keep up with demand. To maintain grape quality and avoid spoilage, the winery brought in a 500 kW rental chiller from Aircon Rentals.

Our team designed and deployed a complete temporary cooling package — including buffer tank, pump, hoses, and cabling — within just 48 hours. The solution provided both the extra cooling capacity required and a layer of redundancy to protect against system failure.

As a result, the winery maintained continuous production during the critical crush period, safeguarding fruit quality and meeting all contractual obligations.

This is not a one-off scenario. Each year, wineries across Australia encounter similar challenges, whether it’s from hotter vintages, unexpected yield spikes, or aging plant equipment. What sets successful wineries apart is their foresight to include winery chiller hire in their harvest planning. By treating rental equipment as a strategic tool rather than a last-minute fix, they build resilience into their operations, reduce stress on their staff, and protect their brand reputation

Why Winery Chiller Hire Solution is a Smart Investment

Being under-capacity doesn’t have to ruin your vintage. Renting winery chillers offers a flexible, cost-effective way to maintain quality during harvest — whether you’re boosting capacity or dealing with an emergency.

Beyond avoiding spoilage, chiller hire also allows winemakers to test new techniques, expand production temporarily, and focus resources where they’re needed most. It’s a way to safeguard not just your current vintage, but also your long-term market credibility.
