users’ top priority tends to be reliability of supply followed closely by energy efficiency and compliance with current legislation. It is, therefore, increasingly important for engineers to have tools that can help them accurately match equipment output to demand to ensure the longevity of the equipment; as well as efficient operation. While the SELECT programme has


been available for almost 20 years, the 2019 version includes a number of new features along with the company’s current high efficiency gas­ fired water heater products. It can be quickly and easily downloaded from the Lochinvar website. The user­friendly programme covers 20


different building types, including educational facilities, hotels and industrial plant. Data is entered via a ‘virtual walkthrough’ process and default settings are included where appropriate. SELECT helps designers of hot water systems calculate the most suitable product(s) to meet peak demand periods and the volume of hot water needed for the building in question. Most traditional hot water sizing methods


are based on indirect systems with an emphasis on hot water storage. The advantage of direct gas­fired water heaters is that they work on low storage, but with fast recovery rates and SELECT 2019 prioritises continuous output.

reputation for both the quality and variety that it offers its dedicated global consumers today. One such recent example of this continuing success can be found in a production plant outside Verona, at the IIe Grupo Vin Italiano site, where they are responsible for bottling and distributing 39 million bottles of wine, all around the world, each year.


Maintaining consistent quality is of paramount importance and part of this process is delivering key ingredients precisely. This is where Grundfos dosing pumps play their role in ensuring the uniformity of the output, via a bespoke system that incorporates

This ability to be able to develop the system sophistication that will guarantee the consistent delivery demanded by such an exacting application, all comes down to providing modern solutions to support this ancient ritual, that shows no sign of falling out of favour. Grundfos are proud to play their part and raise a glass to say ʻSalutiʼ to the next 6000 years. To see more case story examples visit:

projects need to meet certain energy efficiency criteria. This is usually assessed by software such as SBEM, which measures the design against current energy standards. Using the manufacturer’s software allows the specifier/contractor to claim an additional two efficiency credits within SBEM and other energy modelling software. The SELECT programme enables the user to choose any combination from a single water heater up to a maximum of four units, but Lochinvar has noted significant growth in the number of large commercial projects requiring multiple heaters, with the EcoKnight range being the most popular for these applications. The upgraded SELECT software, therefore, allows the designer to choose up to six of these models. Multiple water heaters are often installed


where building owners or occupiers want to ensure that ‘stand­by’ is provided. SELECT allows users to establish the combined duty of


a multiple water heater project, giving them the ability to choose the proportion of stand­ by required.


When all the criteria has been added,


SELECT will publish the assessed hot water demand in terms of hot water volume and peak demand period; and the selection results screen will provide up to three water heater options. This section of SELECT displays basic product details such as storage capacity, hot water recovery rate, duty versus demand and storage heat­up time.


Once a selection has been made, the user


can print out a PDF summary of the sizing calculation and save it in the programme for future reference. They can also email the calculation to a third party, including Lochinvar if they wish to request a quotation. There is also an automatic link to the relevant webpage for users to view more product information.

www.belimo.co.uk SKY’s the limit for new Swegon chillers S


wegon has introduced a new range of high­performance chillers onto the UK market.


Part of the company’s new energy


efficient SKY range, the KAPPA SKY offers an attractive combination of state­of­the­art control technology with inverter screw compressors and a choice of low global warming potential (GWP) refrigerants. The new models have been designed


to meet the twin regulatory challenges of the European EcoDesign Directive that is driving innovation in energy efficient performance and the F­Gas Regulation, which is dictating a gradual phase down of high GWP refrigerant gases. The KAPPA SKY products already


meet the energy efficiency requirements of the EcoDesign Directive Tier 2, which does not come into force until 2021 – so giving end users’ a future­proofed solution. The new Swegon chillers operate with the very low GWP refrigerant R513A as a default option, although they can also operate with R134a. The former has a GWP of just 573, making it


Shortages Higher GWP gases are being removed from the market first, which is already leading to severe shortages of some widely used gases and, therefore, significant price rises. Opting for low GWP 513A, which is also non­ flammable, insulates users from this problem. Swegon’s SKY range also offers an


ultra­low GWP option, which uses the new industry breakthrough refrigerant HFO 1234ze. This has the lowest available GWP on the market of less than 1 so is not subject to the F­Gas phase down.


The 32mm microchannel condenser


coils allow the chillers to achieve higher capacities, but with a lower refrigerant charge than previous models. This means the chillers can deliver high efficiency operation from a smaller footprint and Swegon has also manufactured special ‘compact’ models that are ideal for use where space is at

a premium such as in many replacement projects. Also available are modular ‘free


cooling’ versions, which are ideal for year­round cooling demand taking advantage of the UK’s temperate climate to dramatically reduce energy costs.


Across the range, the proprietary BlueThink controls manage the operation of the inverter, compressor speed and variable valve ports. This allows for closely controlled part load operation of the chiller to maximise energy savings and extend operating life as well as remote monitoring for service


and maintenance purposes. Swegon’s SKY chillers have two levels


of inverter control – full inverter and hybrid – depending on the performance needed for the project in hand. There are special low noise versions available too.
