ColdLogik InRow Cooler

InRow Cooling

The coupling of InRow coolers and aisle containment provide greater precision cooling over old fashioned data centers set-ups such as CRAC based designs.

Aside from taking up less real estate, adding flexibility by creating POD based system and removing the need for raised flooring, the overall design allows for higher cabinet heat loads. In fact the CL80 InRow is capable of handling up to 74kW sensible cooling per system.

The combination of EC fan technology, managed air flow, water volume control and the incorporation of the ColdLogik Management System culminate in a cooling system that can grow with your heat loads.

Crucially the CL80 InRow can give a 60% energy saving over traditional data center designs.

CL80 InRow Overview

CL80 InRow Cooler

Each CL80 InRow cooler is fitted with a ColdLogik management system ‘CMS’. The parameters continually adjust to meet the heat load demand, providing optimum energy efficiency

ColdLogik management system ‘CMS’.

Controlled aisle environment

The ColdLogik Management System ‘CMS’ lies at the heart of the InRow solution.

The cold aisle temperature is controlled at the return air from the InRow by the ‘CMS’. Automatically adjusting fan speeds, water flow rate and, if necessary, the output water temperature from the chiller with no operator intervention.

The whole process can also be overseen and controlled at individual cabinet level, room level and remotely via many of the industry standard communication protocols.

The ColdLogik system operates on a ‘sensible cooling’ principle – ‘water above dew point’ with the system remaining free of condensation.

Data center monitoring

ColdLogik RMS
ColdLogik RMS monitor can monitor up to either 100 devices or 300 devices

The ColdLogik solution may be supplied with an optional Room Management System ‘RMS’. The Unit can be fitted inside or outside the DC at the entrance to the data hall for instance, monitoring the operational condition of the DC or any individual connected item.

It is designed to provide ‘all’ details of the ColdLogik Data Center cooling, interfacing before the Building Management System, but working with any BMS installed.

The ‘RMS’ uses Modbus over TCP/IP communication to access information from each ColdLogik unit (CMS - ColdLogik Management System – built into each cooler).

The ‘RMS’ has an IP address (Network port), six USB ports and options to upgrade the built-in software with various ‘control or logic’ options. The unit is “bare” until the ColdLogik installation data is programmed in.

InRow cooling and containment

cl80 containment scaled

Conventional data center cooling relies on the room being flooded with cold air which works well at minimal power densities. In row cooling offers increased capacity and power efficiencies by focusing cooling at the actual load perimeter of the aisle containment rather than relying on the air conditioner from the room itself.

In row units comprise a heat exchange coil which utilises chilled water as the cooling medium which is supplied by the external chiller system.

In row cooling is an efficient and ideal solution for high density data centers without affecting the baseline cooling and humidity control of room based CRAC units.

CL80 InRow cooler

In-row cooling technology is a type of air conditioning system commonly used for data center cooling which the cooling unit is placed between the server cabinets in a row to air to the server equipment's more effectively. In-row cooling systems use a horizontal airflow pattern utilising hot aisle/cold aisle configurations and they potentially only need occupy one-half rack of row space without any additional side clearance space.

The in-row cooling unit draws warm exhaust air directly from the hot aisle, cools it and distributes it to the cold aisle. This ensures that inlet temperatures are steady for precise operation. Coupling the air conditioning with the heat source produces an efficient direct return air path; this is called “close coupled cooling,” which also lowers the fan energy required. In-row cooling also prevents the mixing of hot and cold air, thus increasing efficiency.
