DC split air conditioning units

DC Split Air Conditioning Units for Data Centres and Telecoms Cooling product range by Dantherm Group

Why choose DC split air conditioning units?

Effective cooling in data centres and telecoms is crucial. Without a consistent, reliable way to keep the technology within these sites at optimal temperatures, the risk of overheating and breakdowns grows – leading to expensive repairs and downtime.

Our highly efficient DC split air conditioning units help ensure your technology is safe from heat stress through electronics cooling. These unique solutions run purely on DC power rather than the conventional AC used on a wide range of air conditioning systems. As a result, our units use less energy while generating considerable cooling power in your data centres and telecom sites.

These wall-mounted air conditioning units draw warm air from the top of cabinets and return cooled air at the bottom in a closed loop. As heat is transferred outside by a refrigerant system, no dust or humidity from the outside is allowed to enter indoors.

Because our DC split air conditioners are capacity regulated, only the exact amount of cooling is provided to any given location. This ensures that our units are far more efficient to run than traditional air conditioners, inverter-based DC air conditioners or portable DC air conditioners without inverters.

In addition, our low voltage disconnect feature prolongs battery life. This makes our air conditioners highly suitable for sites with battery backup power and hybrid sites powered by renewable energy sources, such as solar power or wind power. This also helps to guarantee site uptime even during power outages and intermittent power.

Plus, because our split solutions fit most standard split AC air conditioners in size, in replacement installations our units can often use the existing bores of the previous models.

Ensuring clean environments, constant air circulation and no power loss in conversion due to the lack of an inverter, our DC split air conditioning units deliver cooling on demand in an energy-conscious, cost-effective manner, with expected service lives of 10 years.

DC split air-conditioning units: Frequently Asked Questions

What is a DC split air-conditioning unit?

DC split air-conditioners have capabilities that extend far beyond those of conventional comfort A/C systems, making them ideal for regulating temperatures inside data centres and telecom shelters.

Efficiently operating all year long, DC split air-con units prevent heat from exceeding safe levels and damaging key equipment or disrupting critical networks.

How does a DC split air-conditioning unit work?

This technology is often mounted on walls, where units continuously transfer heat outdoors through a refrigerant system, creating a closed loop of cool air as a result.

Warm air is drawn from the top of electronics shelters, cooled, and then fed in at the bottom of these spaces. This helps create and maintain the ideal environment for equipment to operate in, where temperatures are controlled and contaminants such as dust, humidity and pollution are kept out.

What are the benefits of using a DC split air-conditioning unit?

Guided by decades of experience, our DC split air-conditioning units are capacity regulated, delivering the precise amount of cool air to a space, as and when required. This not only helps minimise energy consumption, it also reduces operating costs.

As well as being highly efficient and sustainable, all of our market-leading technology is easy to use, reliable, and effective. Plus, because our split solutions fit most standard split AC air-conditioners in size, our units can easily replace existing installations.

Furthermore, by using a closed loop to cool these spaces, sensitive electronic shelters environments stay free of dust, sand and other contaminants, without the need for additional air cleaning devices.

How do I choose the right size DC split air-conditioning unit for my space?

Most electronic equipment is sensitive to temperature. But, not all will have identical cooling demands. For example, Uninterruptible Power Supply (UPS) equipment requires temperatures between 20°C and 30°C, while radio equipment can operate effectively between 30°C and 55°C.

Selecting the right sized unit for your electronic shelter is crucial, but outside conditions, the size of a space, and the precise cooling demands of equipment can all influence which unit is best for your setting.

Our team of professionals are totally committed to accommodating your needs. By developing a complete understanding of your project, we specify your optimal solution, using the experience we have accrued from tens of thousands of successful installations across Europe.

Can a DC split air-conditioning unit be integrated with a renewable energy system?

Yes. As part of our commitment to sustainability, our market-leading DC split air-conditioning units feature a low voltage disconnect feature that prolongs battery life and allows our range to be powered by renewable energy sources, such as solar power or wind power.

How does a DC split air-conditioning unit compare to a traditional AC unit in terms of energy efficiency?

Dantherm Group DC split air-conditioners are capacity regulated, meaning only the exact amount of cool air is provided on-site when it is needed. This makes our split air-con substantially more efficient to run than traditional AC air-conditioners.
