Powerful pre-cooling system for data centres
SINGAPORE-BASED ST ENGINEERING has launched its new Airbitat DC Cooling System, marking its entry into the data centre cooling market.
An innovation by its Urban Environment Solu- tions (UES) business, the Airbitat DC Cooling System delivers powerful pre-cooling for tropical data centres, achieving annual net energy savings of more than 20 per cent over conventional chiller systems alone.
This translates to annual energy savings of about $104 per kW[1] of heat load.
Combined with existing chiller systems, the Airbitat DC Cooling System enables data centres to reach a targeted Power Usage Effectiveness[2] (PUE) of below 1.3, which is supported by UES’ live system data and backed by eight years of engineering, R&D and its patented evaporative cooling technology.
Head of Urban Environment Solutions at ST Engineering, Gareth Tang, said the team re- engineered its established Airbitat solution.
“We have successfully developed a sustainable solution that significantly cuts energy consump- tion while reducing carbon intensity and Urban Heat Island Effect,” he said.
“Its ability to be readily deployed in existing data centres presents an attractive option for operators who are looking for cost-effective solu-

tions to lower energy consumption and achieve their sustainability targets.”
Backed by extensive R&D, the Airbitat DC Cooling System comprises a Dual Coil Computer Room Air Handler (CRAH) and a Deep Cooling Unit that’s powered by the patented Reevac® Deep Cooling technology.
High performance, compact blower
RADIFLEX IS THE new EC blower released by ebm-papst.
With the new RadiFlex, ebm-papst has devel- oped an economical, high-performance blower for a wide range of applications that can be flex- ibly integrated into a wide range of hood types.
The compact RadiFlex delivers a lot of power with low energy consumption.
In terms of energy efficiency, there are numerous correlations with the design, function and suction power, regardless of whether the range hood is a built-in, diagonal, chimney or island hood.
The RadiFlex's standardised connections enable it to be easily installed in range hoods. The housing is designed so that it can be used in almost any type of hood.
For exhaust air mode, the blower is available with an optional non-return valve. This prevents the exhaust air from flowing back or outside air from flowing in. Protection against contact is integrated on the intake side as standard.
Activated carbon filters for odour filtering can be attached at any time using the bayonet fit- tings on the housing. In addition to traditional exhaust air mode, the RadiFlex is also ideal for circulated air mode, which supports an energy- efficient construction and living.
The dual flow blower can convey up to 930 cubic meters of air per hour (free air). Thanks to EC technology and a three-phase motor, it is possible to achieve high speeds without
impairing the acoustics.
Due to its high power density, the inte-
grated EC motor is more compact and therefore consumes significantly fewer resources and weighs much less than a comparable AC motor: The total weight of the RadiFlex is only 1.9 kilograms, meaning that it is up to 20 per cent lighter than compa-
rable EC blowers.
FAN WITH A HIGH IQ
EBM‐Papst has developed the iQ‐one EC motor, which enables an output power of up to 5W for refrigeration applications.
The iQ‐one can be combined with fan impellers of 154, 172 and 200mm diameter. It is described as an efficient fan solution for a wide range of applications, especially with aerodynamically optimised fan impellers of 172 and 200mm and particularly in supermarkets, where many fans operate continuously.
