Emerson
Emerson is releasing an expansion to its Copeland Discus III compressor line, with new 4DA/4DE and 6DU/6DV/6DZ models. These will help meet customer requests in a multitude of spaces, including food retail and foodservice as well as scientifi c plants and laboratories. The new models are currently available for purchase and installation.
The 4DA/4DE models are Copeland’s smallest capacity four-cylinder Discus compressors and are targeted toward foodservice and food retail applications such as condensing units, supermarket racks, environmental chambers and process chillers. The 6DU/6DV/6DZ models are Copeland’s largest capacity six-cylinder Discus compressors and are intended for use in the foodservice and food retail space as well as scientifi c plants and laboratories. These models increase the six- cylinder capacity by more than 20%, off ering users a signifi cant capacity increase without increasing footprint.

Airedale
Data centre cooling solutions provider Airedale International Air Conditioning unveiled its new fan wall solution, AireWall, at the Data Centre World Exhibition in London.
This latest product in Airedale’s IT cooling portfolio is an evolution of a bespoke air handling unit that has been supplied by Airedale for several years, and is Ideal for application on solid fl oor data centre installations with hot aisle containment. Evolving data centre requirements and fi eld knowledge have led to the
development of this precision Computer Room Air Handling (CRAH) unit, designed specifi cally for low energy, high density data centre applications.
It removes the need for pressurised raised fl oor systems and overhead cooling systems, and with options ranging from 170- 400kW cooling power, it gives more fl exibility and scalability to data centre operators.
Engie
Engie Refrigeration is redesigning its entire air-cooled Quantum series in response to changing customer requirements. New Quantum Air models will be available worldwide from 24 June 2019. Jochen Hornung, chief executive of Engie Refrigeration, said: “The requirements for the refrigeration industry have changed in recent years. Our customers are placing increasing value on greater effi ciency and performance in their chillers, for example. We are accommodating these changing conditions by redesigning our air-cooled Quantum series.”
On the launch date, Engie Refrigeration will off er 28 basic models of the Quantum Air. 14 of these models use the refrigerant R-1234ze, and 14 models use the refrigerants R134a and R513A; all of them require lower quantities of refrigerant. Like its predecessor model, the revised chiller is ideal for use in a variety of industries – from automotive manufacturers and suppliers to the chemicals and pharmaceuticals industry, industrial production and data centres. Engie Refrigeration has also combined the individual machine components in a new way, so that the Quantum Air surpasses even the exceedingly high effi ciency of the current series. The chiller is suitable for applications from 250kW to 2MW and with its Supersilent package, the Quantum Air is as quiet as a whisper, perfect for noise-sensitive applications in hospitals and offi ce buildings, for example.

Delivering uniform cooling airfl ow to data centre equipment, the AireWall comprises a fi lter and fan bank, a damper section and a chilled water heat exchanger. The damper section can be installed separately to maintain a clean data hall environment and individual sections can be removed for maintenance.
AireWall’s integrated, intelligent controls mean it is self- regulating and highly adaptive to changing loads, and the range has been designed to operate at low SFP to help achieve low installation PUE.
In addition, the product’s fl exible and modular design lends itself to new build data centres as well as upgrades, capacity expansions and equipment replacements in existing facilities. Maintenance costs are typically lower than other cooling solutions due to easy, direct access via the plant room, and the absence of computer room air conditioning (CRAC) units frees up more space in the data centre for direct business use. Airedale has developed the AireWall range for use with the new
Bluefi n fans from Ziehl-Abegg. Taking inspiration from the fi n of the humpback whale, these have a bionic design, are airfl ow optimised and boast an effi ciency increase of up to 15%. The corrugated blades ensure an optimised fl ow angle and reduced fl ow separation of the blade surface for a diff use sound output and signifi cantly reduced noise. Quieter than more typical air cooling methods and available with either a 4, 6, or 8 fan and 6, 8, or 10 row coil confi gurations, the AireWall is a fl exible and powerful solution for data centre cooling.
