For Commercial & Industrial Hire
Aircon Rentals offers evaporative cooling units for hire, giving you a simple and energy-efficient way to improve comfort in warm conditions. Designed to deliver strong airflow, these portable units reduce heat stress across open or semi-open environments where traditional air conditioning may not be practical. They are commonly used in warehouses, workshops, outdoor events and hospitality areas, making them a reliable option for businesses looking for an air cooler hire solution.
Cools up to 95m2 to 370m2 floor area
Our evaporative coolers are available in a range of sizes designed to support different floor areas, ranging from compact 36L models to high-output 60L units.
- Smaller units are ideal for targeted cooling in workstations, service areas or staff rest zones.
- Larger units can support broad airflow across bigger open spaces, providing comfort over wide floor areas and improving ventilation in hot environments.
This flexibility makes them ideal for environments that need broad airflow coverage without installing fixed commercial cooling systems. Each unit is easy to position and delivers steady performance across wide, open layouts.
How evaporative cooling compares to traditional air conditioning
Choosing the right temporary cooling solution depends on your site layout, ventilation, humidity levels and temperature control requirements.
Traditional refrigerated air conditioning uses a refrigeration cycle to remove heat from the air and reject it outside the cooled space. Evaporative cooling works differently. It uses the natural evaporation of water to reduce air temperature while supplying a steady flow of fresh air into the area.
The table below outlines how these two rental cooling options perform across different environments:
| Feature | Portable Evaporative Coolers | Traditional Refrigerated AC |
| Best Environment | Open layouts, workshops, warehouses, loading bays and well-ventilated areas | Enclosed indoor rooms, offices, control rooms, server rooms and moisture-sensitive spaces |
| Air Supply | Supplies fresh outside air when installed correctly | Primarily cools and recirculates indoor air |
| Site Requirements | Requires good ventilation, with open doors, windows or exhaust paths | Works best in enclosed areas where cooled air can be contained |
| Heat Rejection | No exhaust hose or external condenser required | Requires heat to be rejected outside through ducting, condenser airflow or an external unit |
| Energy Profile | Lower electricity consumption because there is no compressor | Higher power draw due to compressor-based cooling |
For enclosed spaces that need controlled temperature and humidity, a commercial air conditioning hire solution is usually the better option. For large, open or well-ventilated spaces where doors are frequently open, an evaporative cooling setup can provide efficient temperature relief with simpler installation requirements.
Provides strong airflow for open and semi-open spaces
Evaporative cooling is well-suited to areas where heat builds quickly and air circulation is essential. These units generate a high volume of fresh, cool air that helps improve comfort for staff, guests or customers. They are often used in places where warm conditions impact productivity, including manufacturing floors, loading bays and temporary outdoor structures.
Energy-efficient cooling with a simple setup
One of the benefits of evaporative cooling is its low energy consumption compared to traditional air conditioners. Units require only water and power to operate, which keeps running costs low while maintaining reliable cooling output. Setup is also straightforward, allowing you to integrate the system into your space with minimal disruption.

FAQs
How effective are evaporative coolers in hot weather?
Evaporative coolers are highly effective in hot, dry weather and can reduce air temperature by around 5°C to 12°C. They rely on low relative humidity to evaporate water efficiently. As humidity rises, their cooling performance decreases, though they still provide relief via strong airflow.
What types of spaces are best suited to evaporative cooling?
They are best suited to large, well-ventilated, open or semi-open spaces. Typical applications include manufacturing workshops, warehouses, loading bays, automotive garages and agricultural sheds where traditional, sealed air conditioning is impractical or too costly to operate.
How do I choose the right size evaporative cooler?
Selection depends on total floor area, ceiling height and heat load. Compact 36L units work well for targeted spot cooling at specific workstations, while heavy-duty 60L models are required to handle broad airflow ventilation across large industrial layouts up to 370m².
Can evaporative coolers be used outdoors?
Yes. Because they do not require a sealed environment or exhaust ducting to reject heat. They can be used outdoors where there is suitable airflow and access to water and power. They are frequently deployed in open-air hospitality areas, marquee events, festival stages and construction zones to deliver a constant, fresh breeze.
Are evaporative coolers expensive to run?
No. They are incredibly cost-effective because they only draw power for a fan motor and a small water pump. They consume significantly less electricity than compressor-driven refrigerated systems, significantly reducing operational energy costs.
Can evaporative coolers be hired alongside other cooling equipment?
Yes. For comprehensive climate control, you can choose an evaporative cooling for hire package and combine it with a portable refrigerated air conditioning unit to manage sealed offices while using evaporative units to handle open production floors and high-traffic loading zones simultaneously.
