New data center cooling unit from Stulz hits the market

Stulz, a specialist in mission-critical cooling solutions, has added a new chiller to its portfolio.

The chillers have stepless capacity control (EC compressor) and an output of 20 to 100kW.

Stulz's series of CyberCool chillers are designed for indoor installation, and the new version has been specifically engineered to precisely adapt to low or fluctuating heat loads.

With a maximised temperature range from 4 to 18 °C at the chilled water outlet, the CyberCool Indoor series is suitable for a broad range of applications such as in the data center, in medical technology or the process industry.

Chillers from Stulz 's CyberCool Indoor series are available with a choice of three systems: air-cooled with external condenser, water-cooled, or the TCO-Leader with Indirect Free Cooling and intelligent mode switching (compressor cooling, free cooling or mixed mode).

All three systems can be standardly equipped with ON/OFF compressors or with new energy-saving EC compressors.

These EC versions contain two complete, redundant refrigerant circuits and ensure high efficiency in partial load. According to Stulz, the system reacts quickly to dynamic load fluctuations avoiding ON/OFF cycling to guarantee an extended equipment life.

The Indoor chillers are designed to fit through all standard doorways. The separation of indoor unit and external condenser/dry cooler as well as the general use of low noise components meet stringent noise restrictions.

According to Stulz, installing the chiller close to the consumer unit reduces heat losses while still ensuring energy-efficient, reliable cooling.

Another key benefit is that the design of all CyberCool Indoor units allows easy maintenance because important components such as compressors, expansion valves and pumps are accessible from the front. And on that note, Stulz says it can offer an extensive portfolio of options including a global network with prompt service and proactive support.
