EHX compressor
The EHX R290 compressor from Embraco is a compressor family strongly focused on the Asian market , being manufactured in Nidec Global Appliance ’ s Chinese site . It is a robust platform especially suitable for frozen food islands , kitchen reach-ins , ice cream freezers and large coolers , offering robustness and energy savings . In comparison to the NEU platform , it presents an increase of 5 % in energy efficiency .
The Embraco EHX compressor runs on hydrocarbon refrigerant R290 , thus having no ozone depletion potential and a global warming potential close to zero . It is manufactured in Nidec Global
Compressor technology boosts chiller energy efficiencies
Aermec has harnessed modern technologies and launched Aersave , a groundbreaking compressor technology that can help customers improve their chiller ’ s energy efficiency and deliver up to 50 % in energy savings .
Compressors on chillers are large energy users , and replacing them with more energy efficient systems is primarily the only solution . Aersave offers a cost-effective alternative .
The Aersave smart compressor controller converts any three-phase fixed speed compressor to a variable speed compressor .
• Aersave can be used with any manufacturers ’ chillers
• Aersave operates with any refrigerant
• Aersave is compatible with all brands of BMS systems
By enabling compressors to work smarter , Aersave eases reliance on the electrical grid , increases reliability , offers compressor protection , and can easily be retrofitted by any air-conditioning or refrigerant engineer .
The benefits are a compact unit , decreased noise levels , precise room temperature and humidity control , which protects the compressor from short cycling and there is no interference with any of one ’ s chillers ’ existing controls .
Aersave comprises two sensors instead of pressure transducers . One connects onto the suction line of the compressor , the other to the discharge line .
Its unique compressor control gathers the temperature from the two sensors ’ points , together with gathering data via Modbus from the device via the compressor , which are then input to an algorithm that calculates the speed and compressor capacity required for the complete system to achieve its demand capacity .
While working on lower frequency for prolonged periods of time , an oil return sequence brings the oil back to the compressor to protect it .

Aermec has a long history of innovative manufacturing .
Aersave also has multiple dip switch settings that can be switched dependent on the compressor type – whether it is a reciprocating or scroll . It also controls the fan motor whether it is a condenser or evaporator fan motor . As the technology can work with any type of refrigerant , there is no need to cut into the refrigerant line .
The compressor technology was successfully trialed by one of the largest fresh food manufacturers in Ireland , where the chiller delivered a reduction in electrical consumption of 41 %.
KEY FEATURES :
• Converts any three-phase fixed speed compressor to a variable speed
• Controls and monitors the compressor with temperature sensors
• Protects the compressor from working with abnormally high discharge temperatures
• Voltage optimisation and eliminates inrush current

The launch of AireWall ONE
Airedale by Modine , the critical cooling specialists , has announced the launch of AireWall ONETM , a fan wall developed in collaboration with the data centre industry .
AireWall ONE has built-in flexibility with a parametric design allowing it to be configurable to physical space and is designed to operate in sustainable facilities that prioritise energy efficiency . AireWall ONE will be manufactured in Spain , the UK and the US for shipment globally .
AireWall ONE is a customer-led product , developed from the ground-up with considerable input from data centre endusers , consultants and contractors alike . The new range capitalises on the sustainability potential offered in data centres utilising higher air and water temperatures , delivering energy efficiency benefits across the whole cooling system . A parametric configuration philosophy is at the heart of its design – with over 33 000 size permutations , clients can configure AireWall ONE to suit a multitude of construction and cooling requirements , within the following parameters :
• 200 – 650kW
• 2 – 12 EC centrifugal fans
• 6 , 8 or 10 coil row options
• Configurable footprint to suit the space
The AireWall ONETM .
Innovations in refrigeration technology
The manifold with intelligent fault analysis : testo 570s .
With testo 570s , the market leader in measurement technology is launching the world ' s first smart manifold that independently detects and highlights anomalies . With it , testo revolutionises long term measurements on refrigeration and air-conditioning systems , and heat pumps . Instead of a long search , anomalies are displayed directly in the testo Smart App . And the manifold breaks other records too , as it also has the world ' s longest service life of up to 360 hours .
INTELLIGENCE , STAMINA AND PRECISION
Error analysis is often time-consuming especially for long-term measurements , and yet anomalies frequently remain undetected . This is exactly what testo will change with its new manifold . The smart app takes over the analysis and reliably finds the anomalies from large amounts of data . This not only ensures that nothing is overlooked , but also saves a considerable amount of time . In addition , the extremely large data memory guarantees maximum data security . testo
Installation and maintenance teams were also heavily involved in the design process of AireWall ONE . Often overlooked in the R & D process , several contractor-friendly features have been designed into the range that simplify on-site manoeuvring , positioning , commissioning and in-service maintenance .
As with all Airedale cooling equipment , AireWall ONE is delivered with the latest helix intelligent controls platform and can be integrated into a complete intelligent cooling system using Airedale ’ s Cooling System Optimizer and ACIS facility management system .

The manifold with intelligent fault analysis : testo 570s .
The manifold also offers new advantages for standard measurements . With the hybrid system of rechargeable battery and battery , another world-first has been integrated , enabling a record runtime of 360 hours . In addition , the precision of the pressure measurement has been increased to 0.25 % fs , so that reliable results are also obtained for systems operating at low pressure .
