Free cooling units

All free cooling systems depend on outside air to keep inside conditions controlled. Nonetheless, these solutions exist in two main categories.

Turbulent free coolers are a specific type of unit that functions by circulating cool air from corner to corner inside a shelter. This process requires more energy, but results in better coverage – ideal for larger facilities housing equipment that causes high heat loads.

Displacement free coolers are another type of solution that works by creating a cushion of cool air. To do this, outside air is supplied toward the bottom of the room, forcing heat up and out. This low-cost approach is best for smaller shelters.

Free coolers deliver target temperatures at a fraction of the cost of a traditional mechanical unit by forgoing the use of compressors – a consumptive component at the heart of practically every conventional air-conditioning system.

In addition to that, free coolers are considerably better for the environment, as they can function without harmful refrigerant gases. Plus, free coolers are up to 95% more energy efficient than traditional A/C, further reducing the carbon footprint of operations.

No. Because free coolers rely on outdoor air to cool, they cannot regulate temperatures on their own in exceptionally hot climates.

In settings like this, a dual-cooling strategy can offer year-round protection by using both free coolers and A/C in tandem. During days where outdoor temperatures are sufficiently cool, free coolers operate. Then, when it gets too hot, air-conditioning takes over, working only when needed.

This blended approach can deliver the best balance of performance and savings in many regions.

Depending on the dimensions of your shelter, as well as the components inside, the ideal size and capacity of a free cooler will vary.
