itsubishi Electric has launched a new Climavenetabranded NX2 range of air source scroll chillers, expanding the NX2


efficiency alongside quality comfort cooling, as well as R410A. The complete range is Eurovent certified and far exceeds the minimum seasonal efficiency level of 2021 imposed by EcoDesign Directive. The systems have been designed for perfect


acoustic wellbeing, and operate at lower noise levels than the previous range, helping them to achieve one of the best sound power levels in the market, while maintaining the same performance and footprint as the standard acoustic version. They are also designed with high levels of seasonal


efficiency in mind, and achieve excellent SEER values that are over 11% higher than the previous range.

New double wall plates with stainless steel panel feedthrough


addition to the usual double wall plates. With this version, installers can easily implement a loop or ring installation behind dry walls and thus comply with the specifications of EN 806 and the drinking water regulation. For drinking water connections, loop or ring line


S


installation is standard nowadays. Only with these installation methods is it possible to implement the requirement that the contents of a drinking water system must be completely replaced after 72 hours at the latest. In addition, the market  especially hygienically very sensitive areas such as hospitals, retirement homes, but also schools  generally requires a drinking water installation made of stainless steel. To meet this growing demand, SANHA now offers


universal doublewall plates equipped with a panel feedthrough in various lengths from 25 to 65 mm. They are made of stainless steel (material number 1.4404) and meet all hygiene requirements as well as the demands for a durable, particularly corrosion resistant drinking water installation. Looping through the pipe prevents stagnation of the drinking water in comparison to the conventional Tpiece installation and thus prevents unwanted germ growth. Ring pipelines with the aid of doublewalled discs also fulfil the objective of the VDI guideline to reduce pressure losses in the pipeline network with smaller dimensions.

commercial and hospitality, Charon is supplied with a ceiling rose and 1.5m suspension kit and is available as fixed output, digital dimmable, emergency backup variants and Luceco’s Wireless Lighting Controls and offers excellent photometric performance, as well as being a very visually pleasing energy saving luminaire. Charon is the largest of the five known natural


satellites of Pluto and appears in Greek and Roman mythology, an impressive affiliation for this contemporary yet elegant modern pendant luminaire!

Smith’s chosen to provide sympathetic heating for a listed building


wanted to refurbish the heating in the building which retains many of the original period features. The owners struggled to get the room temperature above 17°C because of the thick walls and because the wall mounted radiators couldn’t be turned up high enough, to protect the children, to provide sufficient heat to heat the room. Ceiling mounted Caspian UV fan convectors, painted in a colour sympathetic to the wood panelling and décor, were selected and the according to the Director of EEC ‘never has the hall been as warm as now, we’ve never been able to get the temperature beyond 17°C’.

Perfect Balancing for Swegon GOLD www.smithsep.co.uk/case_studies/eec_preschool


in the spotlight has been the subject of rotary heat exchangers (thermal wheels). Ventilation equipment of sufficient quality that has been properly


I


designed as well as being correctly installed and maintained has a very low risk of viral transmissions from rotary heat exchangers. Updated guidance from CIBSE advises that the operating benefits of properly installed and maintained thermal wheels outweigh any risks by far. It’s well known that carry over leakage is highest at low air flow; although they have almost zero transfer of droplet bound pollutants. It is also widely recommended to maintain and operate buildings at higher ventilation rates, as well as maximising outdoor air. The latest function inside the GOLD units designed by


Swegon is the Air Quality Control (AQC) dynamic pressure compensation setting. The perfect amount of pressure balance means we can eliminate leakage between extract and supply air in GOLD air handling units. Not only does the pressure balancing function mean excellent air quality, but it also saves on energy. Additionally, the rotary heat exchangers in our GOLD RX


units are equipped with a purging sector to reduce the risk of extract air leaking into clean supply. By minimising the risk of air and odour transmissions, GOLD’s patented heat exchangers ensure uniquely effective comfort ventilation with their turbulent air flow. With AQC alongside our purge control, this ensures you only get fresh, filtered outdoor air in the supply air to rooms.

Indoor air quality solutions designed for the future


s part of its journey to becoming CO2 neutral by 2050, Daikin has launched


its most sustainable VRV solution yet: the VRV 5 Sseries. The VRV 5 Sseries is the latest


evolution in the manufacturer’s portfolio development, which Daikin is striving to fully convert to lower GWP (Global Warming Potential) refrigerants. The completely new VRV unit has been developed specifically to use R32 refrigerant, while simultaneously being an allround performer suitable for all mini VRV applications. Fully optimised for installation


in rooms as small as 10m2, its factorymounted refrigerant response measures mean no additional leak detection is required. In use, it provides best inclass design versatility with five sound pressure levels down to 39 db(A) and automatic ESP setting up to 45 Pa allowing for ductwork, while the intuitive online and voice controls offer maximum user comfort.


Speaking about the launch,


Martin Passingham, Product & Training Manager at Daikin, said: “We see there being three key stepping stones on our journey to becoming CO2 neutral: through a circular economy, through innovation and through smart use. The introduction of the VRV 5 Sseries is a perfect example of our efforts to innovate and introduce more sustainable solutions to our portfolio.” To find out more about the VRV

Bishopsgate, has got many reasons to be proud of its new lofty position as the second tallest building in the UK. But it’s height isn’t the only thing that makes this impressive combo that integrated advanced office facilities, retail outlets, food destinations, a gym, spa and no less than 1700 cycling spaces, stand out. Now operational, this


impressive structure has interwoven new technology into every aspect and its focus on detail and its awareness of its environmental impact, has contributed towards it gaining a BREEAM rating of Excellent. Contributing towards this are a wide range of the award winning, energy efficient Grundfos pumps and solutions, that are at a very heart of the HVAC, water boosting and pressurisation demands, that are so key within a building of this nature.


Combining its 1.275 million sq.


ft. of office space, it also is the first building to offer in excess of 100,000 sq. ft. of integrated amenity and social spaces. With its fabulous location the views of London are not only spectacular, but are also accessible to visitors, via its free viewing gallery. Grundfos are delighted to have


played their part in such an important project that has so many good points, that have not only changed the skyline of London, it that is also breaking new records for encouraging an improved work/life balance.

When bigger is better  the Grundfos CR/CRN 185


system with simplified pipework, the CR family have continuously evolved to meet a wide range of increasingly exacting demands. Today, the Grundfos CR range of multistage


B


centrifugal pumps are at the heart of so many applications and projects that it would be fair to call them the backbone of commercial, industrial and wastewater pumping demands. With a strong reputation that has been built on


reliability and efficiency these pumps will happily operate as a standalone or in an integrated system and the latest line extension has now seen the CR/CRN 185 join the lineup and means they will be the ideal choice when a project demands a larger pump to meet its demands, as they offer an operating range of up to an impressive 240m3/h and 350m. Additionally these pumps come with the assurance that every single


pump is tested and validated prior to shipping, so when they do arrive with you, they are already preconfigured and wired and are ready to plug & pump. So when you need to select a multistage centrifugal pump for your


new or existing project, choose the Grundfos CR for their proven performance and durability.
