Interview with the product manager

Optimal cooling generation for mission-critical applications

Whether high-performance computing, data centers, industrial facilities or entire buildings, CyberCool WaterTec is well-suited for all of your mission-critical applications. The installation process is straight-forward, thanks to its compact design, even when installation occurs in the vicinity of consumers. Devising bespoke solutions and adding extra features are commonplace for STULZ, and this ensures that we can meet our customers’ every need and reduce any safety risk, however small.

Advantages for cooling data centers

High-performance and reliable cooling for data centers of any size
Partial load optimization and Free Cooling module (option) ensure energy efficiency all-year round
Automatic transfer switch (option) and quick-start function guarantee maximum operational reliability
Integration and maintenance are hassle-free thanks to its compact design and easy dismantlement

Advantages for process and industrial cooling

High-performance and reliable cooling for small and large-scale industrial facilities
Easy integration for both existing liquid cooling systems and new ones
Ideal for mission-critical applications that require high-level efficiency
Broad operating range with chilled water outlet temperatures of 1 °C to 19 °C

Advantages for building cooling

High-performance and reliable cooling of entire buildings (including large buildings such as hospitals)
Operates with minimal noise and vibration (low emissions both in- and outward)
Environmental footprint is very good, as a result of high efficiency and environment-friendly refrigerant
Adapts particularly rapidly to variable loads

Integration and maintenance

Compact design

Installing and replacing chillers is usually associated with a lot of hassle and high costs. In order to relieve the customer when integrating the new unit, STULZ have attached great importance to the compact design of the CyberCool WaterTec. As a result, we are often able to integrate the unit in a pre-assembled state.

Easy to dismantle

The entire design of the CyberCool WaterTec makes life easier for the user – and not just because it takes up minimal space. Its modular design makes the unit very easy to dismantle into separate components, if required. Even the frame, which must adhere to the highest stability requirements, can be easily dismantled. As a result, the water-cooled chiller does not require any effort when being installed, even in difficult conditions, and is always easy to service. In addition, the switch gear cabinet is equipped with hooks at the rear and can be mounted separately on a wall.

Spray evaporator with environment-friendly refrigerant

Up to 70 % less refrigerant

The CyberCool WaterTec is equipped as standard with the innovative spray evaporator technology. It enables the unit to operate with up to 70 % less refrigerant compared to flooded evaporators with the same level of efficiency. This not only helps the environment, but also makes a positive and noticeable difference to procurement costs.

Refrigerant R1234ze has very low global warming potential

The CyberCool WaterTec runs on the environment-friendly refrigerant R1234ze as standard. The HFO refrigerant has a very low global warming potential and is well-suited as a future-proof and efficient alternative to traditional HFC-based refrigerants. This is STULZ’s sustaina-ble solution to the refrigerant shortage which was triggered by the (EU) regulation number 517/2014.

Partial load mode improves efficiency

Depending on the size of the unit, the CyberCool WaterTec is equipped with between 1–4 Turbocor compressors, for partial load-optimized operation. The compressors run with magnetic bearings, which enables the system to operate completely oil-free. The efficient technology works without any friction losses and reduces operating costs.

Free Cooling with CyberCool Free Cooling Booster

Free Cooling is an intelligent solution for minimizing energy-intensive compressor mode and significantly cutting operating costs. Equipped with an additional Free Cooling module, CyberCool WaterTec uses the outside temperature, which offers the greatest potential for savings, especially in cold and temperate climates.

Without complex and extensive planning, the Free Cooling module can be easily integrated and connected to the piping via a Victaulic connection. Thanks to its own control cabinet including SEC.blue controller, optimum control and trouble-free communication with the CyberCool WaterTec are ensured.

Automatic transfer switch

One of the key requirements for mission-critical and sensitive applications is uninterrupted cooling – in the event of a power outage, for example. To guarantee stable cooling capacity in spite of this, STULZ provides the option of an automatic transfer switch fitted directly in the switch gear cabinet. If the primary power supply fails, this is detected automatically and the chilled water-cooling system defaults to a second power source within a minimum of 180 ms.
