Mitsubishi Electric

Mitsubishi Electric is expanding its off ering in the IT cooling market with its new s-MEXT high precision air conditioning systems.

The s-MEXT is a high precision air conditioner that connects directly to Mitsubishi Electric’s DX Mr Slim Power Inverter outdoor units to create a full inverter split system, designed according to the best quality standards and dedicated to the most reliable IT environments. It is also the company’s packaged Computer Room Air Conditioning (CRAC) unit. The units are available in capacities from 6kW up to 42kW and are ideal for applications where high sensible cooling and close control of temperature and humidity are required, such as small and medium sized businesses (enterprise data centres) with on-premises IT cooling requirements. The units are also available in both Upfl ow and Downfl ow variants.


Daikin has launched the VRV IV+ heat pump, featuring a new compressor that delivers a 15% increase in effi ciency. Existing VRV IV features such as Variable Refrigerant Temperature (VRT) and continuous heating during defrost

are matched by a completely redesigned compressor, which is fully optimised for high performance at part loads – the main operation mode throughout the year. VRV IV+ is already compliant with the new ENER LOT21 Tier 2, due to come into force in 2021. The new compressor also addresses a key issue that can arise during low load operation, which is that leaks can occur from the high- pressure side to the low-pressure side in the compression chamber, causing loss of effi ciency. This has been resolved with the inclusion of a back-pressure control port that sends a small amount of high-pressure refrigerant from the compression chamber to the back of the scroll. This boosts seasonal effi ciency, delivering a 15% effi ciency increase.

Conex Bänninger

Conex Bänninger has introduced a new CIBSE- approved CPD programme for heating engineers, designers and installers, focusing on how modern technologies such as press-fi t can benefi t the industry, while also discussing the advantages and disadvantages.

Dan Wild, UK business unit director for Conex Bänninger, said: “The CPD explains the benefi ts of press fi ttings over brazing, push-fi t and compression and as delivery timelines get tighter and costs increase, it is important for installers to fi nd more effi cient ways of working. “The programme discusses the ‘leak before press’ indicator that alerts installers to fi ttings that have not been pressed or have been pressed incorrectly. This feature allows installers to work eff ectively and avoid mistakes.

“Our ultimate aim is to show heating engineers, designers and installers modern technologies that can reduce their lead time and workloads. We want to off er the right training that can help improve confi dence when using Conex Bänninger’s range of fi ttings.” Engineers and designers who would like to book a CPD session, can do so by getting in touch with

JS Air Curtains

JS Air Curtains has released an updated product catalogue including over 450 units and customisation features set to

inspire architects into making a design feature of their entrance’s air barrier system. As well as clear product information and at-a-glance selection guides, the catalogue incorporates lots of images to illustrate the vast array of mounting systems, colours and aesthetic options available.

New to the exposed range is the Essensse Neo air curtain, a highly

effi cient model, ideal for small shops and restaurants as well as offi ce buildings and banks. Its unique ‘straw system outlet’ steadily blows out air at high pressure to provide the best possible seal across a doorway, preventing cold air entering in the winter and air conditioning escaping in the summer.

Kerry Jones, UK and Ireland sales manager at JS Air Curtains, said: “Details of run-cost analysis alongside all the product selection information continues to make the JS Air Curtains catalogue the go-to resource for air curtain specifi ers and buyers.” The catalogue is available as a PDF download or an online fl ip catalogue, or can be requested as hard copy.
