Our precision air-conditioning systems and chillers ensure maximum availability of sensitive IT, medical, industrial and telecommunications equipment around the world, employing highly energy efficient technology that offers considerable operational cost savings over conventional air-conditioning systems. We also provide humidification solutions for electronics rooms, production environments, food storage, archival systems and medical environments. Our engineers have a wealth of experience and can tailor systems to each client’s unique requirements. We have provided thousands of environmental conditioning solutions around the world for server rooms, data centres, clean rooms, technology rooms and telecommunications bases.
We can also provide expert advice and services including:
Room tuning to eliminate hotspots and airflow blockage
Energy audits with thermographic analysis, system calibration or upgrade advice
Regulatory compliance advice regarding refrigerants, leak tests, fire safety and environmental rules
On-site service, maintenance plans and facility management

The 24/7/365 operation of data centres requires reliable, efficient cooling and humidity control to protect sensitive server equipment. The optimum temperature and humidity conditions can be maintained by closed-circuit air-conditioning systems which supply cold air via the raised room floor.
Precision air-conditioning systems that utilise hybrid technology can take advantage of cool outside air, reducing data centre electricity consumption by as much as 40%. Quiet and efficient, they are designed to provide years of reliable, cost-effective operation that will maintain IT availability around the clock.

High density data centres, with multiple blade servers generating a large amount of heat in a small space, can be prone to hotspots that can adversely affect operational reliability. Precision air-conditioning systems that combine liquid cooling and recirculating air can maintain the required room temperature to the specific degree by targeting accumulated heat loads greater than 30 kilowatts with cold water.
The CyberCool Pump & Transfer system maintains separation of the water supply from electrical components by separating the system into two circuits.
The CyberCool Outdoor Chiller supplies chilled water to precision air-conditioning units and can provide up to 235 kilowatts per unit of cooling capacity.
The CyberCool Indoor Data Chiller, with a cooling capacity of up to 100 kilowatts, is a perfect expansion unit for existing systems when targeted direct liquid cooling of hotspots is required.

The reliability, temperature and humidity control requirements of even small server rooms can quickly overwhelm conventional room air-conditioning, potentially adding the cost of failed IT equipment to electricity costs that are already high due to inefficient air-conditioning.
Precision air-conditioning systems efficiently regulate both temperature and humidity, and are designed for cost-saving continuous operation over many years.
We offer the Compact and MiniSpace precision air conditioning systems which offer cooling of server rooms with heat loads of up to 18 and 28 kilowatts, respectively.

The Stulz CyberRow advanced precision air-conditioning unit is a stand-alone component designed for targeted rack cooling. It is available in two sizes, with a choice of four cooling systems:
Chilled water
Direct expansion
Direct expansion and plate condenser
Direct expansion with indirect free cooling
The CyberRow features three adjustable and independent EC fans and an EC compressor with a soft start function that offers 50% lower power consumption. Cooling capacity is precise and controlled in a manner of seconds thanks to an electronic expansion valve.
With its compact footprint and universal rack compatibility, the CyberRow is also an ideal solution for optimising cooling in existing buildings.

Stulz CyberAir with Direct Free Cooling complies with ASHRAE TC 9.9 - 2008 for data centre temperature tolerances while potentially saving huge amounts of money over conventional compressor cooling systems. For example, a savings of EUR 262,000 per year could be realised in a data centre of 800 m2 and a heat load of 1 megawatt.
It is the first precision air-conditioning system in the world to automatically select the optimal operational mode depending on the difference between the room's heat load and the outside air temperature. In cooler weather, the DFC efficiently uses outside air to lower the room temperature. This means that energy-intensive compressor cooling need only be used when absolutely necessary, resulting in a savings of up to 60% in electricity consumption.
