Multi award winning - Low to high density cooling

Energy saving

Up to 98% energy saving over CRAC based solutions. Up to 83% energy savings over aisle containment solutions. Up to 45% energy savings over In-Row cooling.

Unrivalled PUE

Only the ColdLogik CL20 rear cooler has an independently tested PUE figure achieved: Partial load 1.090 to 1.014 and on full load of 1.045

Lower CAPex

Fewer cabinets, increased densities. No aisle containment or raised floor requirements.
Reduction on chiller size, free coolers and over all data centre real-estate.

Lower TCO - Rapid ROI

Lower Total Cost of Ownership—Return Of Investment is significantly faster than other energy efficient cooling solutions due to the substantial energy savings and lower capital expenditure and higher density capability

Hot spot removal

A major contributor to the reduction of hardware lifespan and hardware and software failure is hot spots in cabinets. The intelligent design of the RDHx provides a perfect solution by eliminating them at source.

Condensate free operation

Condensate free operation is based on sensible cooling which operates above dew point.

Data centre room monitoring

The ColdLogik Room Management System ‘RMS’ monitors and manages devices and plant on the ColdLogik network by best optimisation, ensuring the room environment is maintained in the most energy efficient way. RMS can be viewed remotely and locally and provide full access and control.

Controlled room temperature

Our simple end to end solution to effectively control the comms and data centre room environment is the ColdLogik Management System ‘CMS’.
Each RDHx is intelligently managed for optimum efficiency by embedded computers which continually adjust the operational parameters in response to the heat removal demands temperature.

Safety & system resilience leak prevention

In the unlikely event of a pipework breach the unique patented Leak Prevention System ‘LPS’ stop water escaping fromj the pipework allowing the cooling system to continue running unimpaired providing uptime, safety and system resilience.
Additionally to comply with TIA 942 the ColdLogik solution can provide full N+1 redundancy.

Total flexibility - Standard and non-standard ranges

Available as standard in 2 heights and 3 widths, with 7 variants from passive low duty (0.1kW) to active high duty (85kW per cabinet) 110kW version currently in design.
The ColdLogik CL20 rear cooler boasts the most versatile range available with non standard sizes supplied to suit individual requirements.

Retrofit capability

To extend the life of an existing data centre or to maximise the capacity of a smaller number of cabinets can be achieved with the ColdLogik CL20 rear cooler as it can be retrofitted to any non ColdLogik compliant USpace or OEM rack via our universal Interface Frame, without the need to decommission old cabinets or even entire data centres.

Low to high density cooling with one solution in one space

The ColdLogik CL20 rear cooler solution allows deployment of an RDHx to each cabinet or sharing an RDHx to a number of cabinets.
It is possible to combine low and high density cabinets throughout the data centre allowing for future expansion without compromise.

SAN & UPS cabinet cooling

Since its launch in 2007 the CL20 has been designed-in to many solutions, including the cooling of OEM SAN and UPS cabinets. Naturally it is imperative to retain the integrity of the OEM’s product and to this end USystems had already developed an overhead runner system ‘Zero Aisle’ - which negated the need to hinge the cooler to the OEM cabinet. The runner system can be fitted to the top of the cabinet or suspended from the ceiling.

Liquid cooling range

The CL20 Rear cooler range

There are six rear cooler options in six sizes, available in two heights and two widths all as standard. Non-standard options are also available on longer lead times with MOQ’s

With a cooling range of between 0.5kW and 110kW, the CL20 is the most comprehensive range of RDHx in the market.  All models can be retro-fitted to OEM cabinets, alternatively they can be fitted directly to our ColdLogik compliant USpace 4210 cabinet, saving yet more space.

Dx Rear Door cooler

The CL20-Dx Rear Cooler range

With the same aesthetics and construction as the award-winning liquid cooled rear door the Dx cooler is a split system and comes in two heights and two widths as standard with a cooling range of between 3kw and 25kW.

All models can be retro-fitted to OEM cabinets, alternatively they can be fitted directly to our ColdLogik compliant USpace 4210 cabinet, saving yet more space.
