ColdLogik & EDGE LX Plant

EDGE Mini-chillers

A product specially purposed for the EDGE market, the mini-chiller is an inverter driven chiller with a single water pump. Capable of up to 30kW cooling the system is suitable for the vast majority of EDGE deployments and is compatible with the USystems EDGE solutions.

ColdLogik Chillers

The ColdLogik chiller is designed to help keep your data center within the ASHRAE A1 recommended temperature guidelines. By utilising dual water pumps for N+1 design and adhering to the USystems sensible cooling philosophy, a significantly higher water temperature than traditional cooling systems can be implemented, the chiller both improves energy usage and versatility by comparison to its traditional counterparts.

Free Cooling Options

ColdLogik Free Cooling Chillers

The Free Cooling ColdLogik chiller is designed from the ground up to help keep your data center within the ASHRAE A1 recommended temperature guidelines whilst also absorbing as much free cooling as the local environment allows. By utilising dual water pumps for N+1 design and adhering to the USystems sensible cooling philosophy, a significantly higher water temperature than traditional cooling systems can be used, as a result, the chiller both excels in energy usage and redundancy providing optimum ROI for the end user. Its also possible that the mechanical chiller may never need to be run in ideal conditions.

Dry air coolers

Work by providing the cooling source during the times of the year when the ambient is below the temperature required by the cooling system. Fans in the dry air coolers draw in ambient air and use this to cool the water. As the temperature drops, intelligent controls reduce the load on other cooling plant if being used in tandem (chillers), switching them off altogether when the ambient reaches a certain temperature. Up to 100% direct air-cooling can be achieved this way, with the result that the inherent high operating costs of the chiller are reduced and its lifespan greatly extended.

Adiabatic cooling

The wetted surface – Adiabatic Cooling option on dry coolers enables water to be cooled to within 6 °C of ambient wet bulb, water is used to increase the cooling effect when the ambient dry bulb is 3°C above the design wet bulb – for most of the year the unit operates as a conventional Dry Air Cooler. U Systems uses these hydride type coolers to provide cooling solutions that make data centers operate without any mechanical cooling at all!

Cooling Towers

Very similar to the Adiabatic Cooling option, cooling towers provide cooling of water to data centers using ambient air. Cooling towers tend to have much larger duties than traditional dry air coolers or adiabatic coolers making them a very good solution for very large data centers. The downside is the maintenance requirements are increased so this needs to be accounted for during concept design stages.

Cooling Distribution Units and Leak Prevention System

The ColdLogik design principle means only sensible cooling is used to control the data center room temperature. Which means ensuring the water supply temperature to the CL20 rear coolers is above dew point at all times. The CDU design controls the supply water temperature by the use of a heat exchange matrix, meaning that the data center remains condensate free. The unique patented Leak Prevention System ‘LPS’ puts all the cooling pipe work, apparatus and CL20 rear coolers on a negative circuit so in the event of a breach to pipe work or even untightened fittings, water will not escape and the data center will continue to operate uninterrupted until a schedule repair can be carried out.
