Free cooling

Free cooling is cost-effective controlled ventilation – the telecom shelter or enclosure is cooled by means of ambient air without a compressor.

Why choose free cooling units?

Keeping ambient temperatures at optimal levels in data centres is vital. If temperatures rise to levels too high, electronic components can degrade, slow down or become irreparably damaged.

From air traffic control and digital communication to web services and remote conferencing, equipment outages can cause costly disruptions for customers relying on these key digital services.

To keep equipment downtime to a minimum, air temperatures must be regulated year-round. Fulfilling this obligation often means facilities rely on conventional air-conditioning units for electronics cooling everyday.

However, these traditional mechanical cooling systems are costly to operate, with integral compressors requiring large amounts of energy to run. These solutions also rely on refrigerant gases, which release harmful emissions over time.

Free cooling, on the other hand, represents one of the most energy efficient ways to keep electronic components within optimal temperature ranges.

By using cooler ambient outdoor temperatures to create a constant flow of air, these cooling solutions efficiently exhaust heat, and are up to 95% more energy efficient than traditional A/C.

Using no refrigerants to keep conditions regulated, this technology also embodies one of the most environmentally friendly solutions to electronics cooling.

Free cooling units: Frequently Asked Questions

What is a free cooling unit?

To keep critical technology such as web services and mobile networks online at all times, it is important to keep these components at the ideal temperature throughout the year.

Instead of relying on consumptive air-conditioning systems for this task, free coolers direct cool outdoor air over these systems, keeping conditions inside at suitable levels efficiently and economically.

How does a free cooling unit work?

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.

What are the benefits of a free cooling unit?

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.

Are free cooling units suitable for all climates?

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.

How do I determine the right size free cooler?

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

Reach out to our professionals for a free, specialist consultation, and we can advise you on your most suitable solution.

Can a free cooling unit be used as a standalone system?

Yes. In regions that are sufficiently cool all year round, free cooling systems can keep critical equipment operating at the ideal temperature indefinitely.

Can I buy your free cooling units online?

For all of our free cooling units, VAT-registered companies can get a quote very quickly by pressing 'I want to buy' and inserting their enquiry and contact details.

However, you cannot carry out the entire purchasing process on our website. This is because due to the cooler you wish to purchase and your area of residence, you may or may not need to buy through a local Dantherm Group representative. We will facilitate this when you use the 'I want to buy' button for the free cooling units of your choice.

Can I bulk buy free cooling units for a large project?

Yes, we can fulfil bulk orders across our range of free cooling units for large, bespoke projects. Get in contact with our experts or go direct to your local Dantherm Group representative to discuss the exact needs of your project and how we can meet your requirements.

Can I speak to someone for technical advice to buy the right free cooling units?

At Dantherm Group, we pride ourselves on ensuring all solutions we supply are tailored to your precise needs. Our decades of experience and total control over the design and manufacture of our range of free cooling units means we can provide you with bespoke, technical advice to ensure you receive the most efficient, effective and sustainable solution.

Reach out to our experts for a free, specialist consultation about your specifications so we can advise you on the most suitable system.

What is your delivery time for free cooling units?

This depends. For some standard free coolers, as well as their accessories and consumables, we offer day-to-day delivery. Larger or more complex orders will likely have a longer lead time.

For detailed information on when you can expect to receive the solutions you are interested in, please reach out to your local Dantherm Group representative.

Do you sell free cooling units to private individuals?

No. Dantherm Group free coolers included on this website are sold only to industry professionals either directly or via our extensive network of suppliers.

Do you provide support, servicing and parts for these free cooling units?

Yes. We have dedicated offices, suppliers and servicing partners based across Europe to provide timely, ongoing support across our entire range of free coolers. You can get in touch through our contact form and we will make sure your enquiry is handled by the office or service partner best suited to your needs.

We also have an extensive network of spare parts dealers throughout Europe, who are geared to provide you with a complete stock of spare parts for your units. We are committed to catering to your needs and getting you the required parts as quickly and easily as possible.
