A uniquely modular upgradable ‘passive to proactive’ rear door cooler
Zero running costs
- No electrical components, relies on the fans of the active equipment for cooling
- Hang RDC directly to the cabinet via interface frame and then it only requires water connection to complete installation
Lower capital cost
- No fans, no controller or monitoring simply the rear door and coil
- No external fans when running as passive model
Condensate free operation
Condensate free operation is based on sensible cooling which operates at ‘dew point’. This prevents condensate from forming while ensuring a more efficient operation of the external equipment.
How it works
CL20 rear of cabinet passive cooler, relies solely upon the active equipment fans producing enough air volume to in effect 'self cool'
How a passive RDC works
Ambient air is pulled into the cabinet via the active equipment fans. The hot exhaust air produced by the active equipment then passes over a heat exchanger matrix by its own velocity, heat is then transferred and rejected to coolant. The resulting chilled air then passes back into the room.
Cooling distribution unit and leak prevention system
Another unique and important attribute of the ColdLogik solution is the option of a patented Leak Prevention System (LPS), which is incorporated within the Cooling Distribution Unit 'CDU'. As water is present in most data centers, they have the same inherent weaknesses – such as leak detection systems shutting down parts of the cooling system when moisture is detected. In the event of a pipework breach, the LPS – Leak Prevention System – stops water escaping from the pipework and allows the cooling system to continue running unimpaired, providing uptime, safety and system resilience
External cooling options
External cooling selection is less restrictive with a ColdLogik system – in many cases you do not have to rely on traditional mechanical cooling products such as chillers. This is primarily due to the design and control functions of the CL20 rear coolers – the rear coolers utilise much higher water supply temperatures compared to other forms of computer room air-conditioning to achieve the same room ambient temperature. Consequentially, free cooling can be obtained from a wider range of options such as river, lakes or boreholes. When all the facts are taken into account, our bold claim of 93% energy savings over and above standard computer room aircon systems is easily justified.
Smart Passive deployment strategies
One of the biggest advantages of the Smart Passive Rear Door Cooler is its ability attach to a USystems cabinet or another manufacturers cabinet via an interface frame.
The interface frame is a universal product, so all standard and some nonstandard enclosures can be accommodated. It allows a secure fixing of the rear cooler without transferring any additional weight to the existing cabinet.
The frame brings many of the benefits of the CL20 cooler family without the need to decommission old cabinets – or even entire data centers.
NB. Standard recognisable manufacturers racks can be accommodated without feet, castors or plinths. If these are used, a CAD step file would be required of the rack to enable us to design a made to order interface frame.
