Greenhouse Evaporative Cooler

Does your greenhouse turn into an oven on hot summer days? Then this Greenhouse Evaporative Cooler is the answer. It cools the air naturally, using the simple power of evaporation. So it drops the temperature and protects your plants — without the running costs of refrigerated air-conditioning. Above all, it’s energy-efficient, quiet and easy to install. In short, it’s a smart, affordable way to keep your greenhouse cool through the Australian summer.

The design is refreshingly practical. To start, the ultra-slim cabinet fits into places where bulkier coolers simply won’t. So you can mount it through a wall or window with ease. In addition, it runs on a dependable 2-speed motor and includes the exclusive LSP-93 sump pump — one of the most powerful pumps available. As a result, it keeps the cooling pads fully saturated for steady, effective cooling.

How Evaporative Cooling Works (and Why It Suits Australia)

The science is simple but effective. First, a pump keeps the cooling pads wet. Then the fan draws hot, dry air through those wet pads. As the water evaporates, it absorbs heat from the air. So the air that comes out the other side is noticeably cooler and more humid. In a greenhouse, that’s a double win: your plants get relief from the heat and a welcome lift in humidity.

Importantly, evaporative cooling works best in hot, dry conditions. So it’s especially well suited to much of Australia’s summer climate, where the air is hot and dry. As a result, you get effective, low-cost cooling exactly when your plants need it most. In very humid coastal conditions, though, evaporative cooling is less effective — so it’s worth matching the method to your local climate.

H2: Why Greenhouse Cooling Matters

Heat is one of the biggest threats to greenhouse plants. To start, high temperatures stress plants, slow growth and can scorch leaves. In addition, excessive heat reduces fruit set and can ruin a crop. So keeping temperatures down through summer is essential. An evaporative cooler tackles this directly, cooling the air and lifting humidity at the same time. As a result, your plants stay healthier and more productive right through the hottest months.

H2: Cooling Your Greenhouse — A Layered Approach

For best results, combine cooling methods. First, use shade cloth to cut the heat load from the sun before it builds up. Next, add good ventilation and a circulation fan to keep air moving. Then run the evaporative cooler to actively drop the temperature on the hottest days. So rather than relying on one device, you build a layered system. As a result, you keep your greenhouse comfortable even in peak summer heat.

H2: Frequently Asked Questions

How does an evaporative cooler work? It draws hot air through wet pads. As the water evaporates, it absorbs heat. So the air that comes out is cooler and more humid — ideal for plants.

Does it work in Australia? Yes, especially in hot, dry conditions, which suit evaporative cooling well. In very humid coastal areas it’s less effective, so match the method to your climate.

How big an area does it cool? Roughly 9–37m² (100–400 sq ft), making it ideal for small-to-mid greenhouses or spot cooling.

How is it installed? It’s designed for through-the-wall or window mounting, and its slim cabinet fits where bulkier coolers can’t.

Is it cheap to run? Yes. Evaporative cooling uses far less energy than refrigerated air-conditioning, so it’s an economical way to cool a greenhouse.

H2: Conclusion

In the end, this Greenhouse Evaporative Cooler is a smart, low-cost way to beat the summer heat and protect your plants. It cools naturally through evaporation, fits into tight spaces, runs quietly and efficiently, and directs cool air exactly where you need it. Plus, it pairs perfectly with shade cloth and fans for total climate control. So browse our cooling range or get in touch for expert advice today.
