ColdLogik Rear Door Coolers
CL21 Passive Rear Door Heat Exchanger
Product Description
The ColdLogik CL21 Smart Passive is designed to provide high performance cooling with Zero operational costs. The performance is entirely dependent on the active equipment inside the cabinet, and the available static pressure. At 14° C / 57.2°F Water inlet, the CL21 Smart Passive is able to supply up to 29kW of cooling. Ideal for a bdata centre targeting a highly sustainable operating structure.

EDGE-3 Soundproof MDC
Product Description
Arguably the best all round performing air-cooled soundproof MDC in the world – the EDGE-3 replaces the need for a dedicated server room and only takes up less than 1m² of valuable office/floor space, allowing localised (Edge) computing in populated or more sensitive locations – especially where there might be a concern of server noise being a distraction or breaching noise at work regulations..

EDGE-5 Air Conditioned MDC
Product Description
Designed specifically to cater for localised Edge computing demands and associated peripherals as a standalone solution, ideally located in a well ventilated room.
The EDGE -5 is a self-contained air-conditioned MDC and is an ideal solution for projects requiring active cooling without the use of an external condenser.
The cooling is provided by an inverter driven direct expansion system, which under the right conditions is 80% more energy efficient than an non-inverter driven AC unit.

ColdLogik is a USystems brand, and denotes a range of cooling solutions including Rear Door Coolers and InRow Coolers
Each Rear Door Cooler and InRow Cooler is fitted with a ColdLogik Management System ‘CMS’ and operates at 50Hz (Phase-Neutral) or 60Hz (Phase-Phase).
Depending on the model and dimensions of the Rear Door Cooler, the dry weight will range from between 63.5kg (140lb) to 79.8kg (176lb). Filled weight between 76.2kg (168lb) to 91.2kg (201lb).
This will be dependent upon data centre location. Please contact our technical team via sales@usystems.com.com for further guidance
Up to 93% has been achieved over older CRAC/H based designs. This is possible because an RDC design data centre is far more energy efficient, using less power to achieve the same level of cooling; furthermore, an RDC design operates at higher supply water temperatures and can therefore utilise ambient free cooling.
What is PUE (Power Usage Effectiveness)?
PUE is a metric used to determine the energy efficiency of a data center. The amount of power entering the data center is divided by the power used to run the active IT equipment
As cooling is the largest area of power consumption in a data centre, this is where the greatest improvements to PUE can be made. As data centre cooling specialists, the USystems ColdLogik product is designed to reduce PUE. This is accomplished by minimising the power draw requirements of the product through use of adaptive intelligence with the ColdLogik Management System. USystems also design solutions to use fluid at warmer temperatures, allowing the maximisation of free cooling potential, therefore dependence on mechanical cooling can be minimised or eliminated altogether. The PUE of the data centre is greatly improved over systems that rely on other technologies.
A PUE of 1.03 has been achieved as of 2020. Many ColdLogik systems are showcased in data centres that have gone on to receive notable recognition and awards centred around efficiency. Customer case studies can be found on our website at: https://usystems.com.com/case-studies/
Water Usage Effectiveness is a sustainability metric used to determine the amount of water used by data centers to cool the IT equipment.
A ColdLogik RDC design is a closed loop system, so when paired with similar mechanical cooling or other free cooling technologies such as borehole, river, sea water etc is totally sustainable. Which means each deployment only uses water at the initial set-up phase. The volume of water required at this stage will vary depending on the scale of the intended data centre deployment. The volume capacity of an individual ColdLogik cooler will range between 5.7L (1.5 US Gallons) to 15.4L (4 US gallons) in volume.
Depending on the operating parameters required (i.e. cooling duty, location, etc) ColdLogik can either operate independently of mechanical cooling, make use of local water sources such as lakes, boreholes, seawater, etc, or use traditional mechanical cooling technology such as chillers, cooling towers, dry air coolers, adiabatic coolers, etc.
Yes. Please contact our technical team via sales@usystems.com.com for further guidance.
USystems recently launched CL23 HPC Rear Door Cooler is capable of 204kW (14°C / 57°F inlet water).
For the medium density requirement, the CL20 is capable of 93kW (14°C / 57°F inlet water). However, using customer specified parameters while on-site, 106kW has been independently tested and verified on the 93kW rated cooler.
Please email sales@usystems.com.com for further information.
This would be dependent upon the chosen model. Please contact our technical team via sales@usystems.com.com for further information
Yes. This can be achieved with an Interface Frame. The Interface Frame provides a bridge between the ColdLogik Rear Door Cooler and any OEM rack. The interface frame is connected to the rack via a fixings kit and as standard fitted directly to the floor to transfer weight load.
Please contact our technical team via sales@usystems.com.com for further information.
Yes. ColdLogik can be retrofit into Legacy installations.
No. Although refrigerant systems are widely utilised, they have their operational limits, complications, and environmental impacts, including but not limited to:
Certified F Gas engineers are required to install or maintain products that use refrigerants. Water-cooled systems do not require this.
The legislation around the use of refrigerants is ever-changing to conform to climate regulations which vary depending on location. Water-cooled systems are free of these restrictions.
Refrigerant systems also operate under high pressures (up to 40 bar). Water-cooled systems typically operate at 3 bar.
Refrigerant systems require the use of constant mechanical cooling to produce the cooling effect while the USystems ColdLogik Rear Door Coolers can operate with little or no mechanical cooling intervention.
Refrigerants are becoming increasingly expensive to purchase due to demand and restrictions.
The static load refers to how much weight a rack can hold when sited and the dynamic load is how much weight a rack can hold when being moved on its castors.
No. It is possible to deploy an RDC to every second or third rack. Please contact our technical team via sales@usystems.com.com for further information
The RDC’s are controlled by the ColdLogik Management System (CMS). The CMS adaptive intelligence is designed to control the whole room environment.
The CMS continuously reads temperature from three zones, before the coil, after the coil, and an external room temperature sensor. The CMS uses the temperature information to control the volume of fluid provided by the valve, and the overall speed of the fans in the cooler. Should the equipment inside the rack on occasion produce more heat, the CMS will react, and increase fan speed / fluid volume to achieve the air off temperature required. In the event of additional temperature changes required, the CMS can demand a change in supply water temperature from mechanical cooling.
