The EWAD-TZ chiller has the same footprint as a non-inverter unit but that is where the similarities end.

At full load eDrive automatically controls energy costs via an electronic adjustment of the pump curve.

About 14 per cent of electricity demand and five per cent of Germany's emissions can be attributed to cooling systems.

To achieve high quality water within the system, filtration once per hour is recommended.

Cooling towers can be characterised by the way in which air is moved.

Energence units are engineered with intelligent features like the Prodigy control system.

All of the waste heat is fully recovered to produce hot water instead of rejecting valuable energy to the air.

The highest ESEER in its class.

The focus is on water conservation awareness.

Ecodrygel coolers operate in a closed-loop clean water circuit.

The GEA GLAC CA2 range also offers interfaces with all common building management systems.

Electronic expansion valves and DC inverter condenser fans are standard.

Danfoss vice president Robert Wilkins said no single refrigerant is suitable for all applications.

Pre-engineered options include heat pump, integrated hydraulic module, total or partial heat recovery and free cooling.

DCIM tools today can test energy outputs on a rack by rack and even server by server level, crucial for organisations with budgetary constraints.

Digital data is doubling every 24 months and could grow 50 times by 2020 which is why the need to find a green solution is so important.
