over a 12‐year period. The iconic 1970s’ Tricorn House building, on the Hagley Road in Birmingham, dominates the skyline and features a highly unusual floor plate. Plenum air conditioning was originally specified in 2004 for one of the 10 floors as an option that would bring cooling to the inner areas of each deep space floor area, whilst maximising headroom in the building with a restrictive 2.8m slab to underside slab height. The ceiling void was reduced from 600mm to 80mm resulting in a net saving of 450mm.

In 2014, slimline Fantiles incorporating EC Fan technology were introduced, which are easily accommodated within the shallow 175mm floor void. All 10 office floors are now air conditioned using underfloor equipment and the latest specification added an additional downflow unit to the specification on previous floors serving increased cooling load requirements through higher density and occupant demand – again demonstrating the suitability of such

www.flexiblespace.com Best practice makes perfect, says Sentinel


ountless breakdowns, premature repairs and parts replacements, and energy wastage in commercial heating and hot


water systems could be prevented with best practice water treatment, says Sentinel Commercial. The boiler manufacturer‐endorsed water treatment specialist is highlighting the need for specifiers, contractors and installers to adopt a water treatment programme that includes system cleaning, protection and maintenance, and suggests that there is a great business opportunity for those that do. Commercial heating systems subject to poor


water treatment practices succumb to corrosion and limescale (the latter where the system is served by hard mains water, which is approximately two thirds of mainland England). The consequences can be disastrous – even complete boiler failure, just months after commissioning, has been known. Furthermore, corrosion and limescale deposits reduce system efficiency and effectiveness, leading to higher energy bills. In addition to immeasurable disruption, these issues can cost an


organisation many thousands of pounds to remedy. A programme of best practice water


treatment is inexpensive and relatively easy. The best practice Sentinel System of ‘clean, protect, maintain’ is simple yet comprehensive; when used in conjunction with high quality, proven, boiler manufacturer‐endorsed water treatment products, the system can help to deliver lifetime protection from corrosion and limescale. “Research by a major boiler manufacturer


found that 87% of boiler call‐outs were to systems without correct water treatment,” said Chris Shelton, Sales Director at Sentinel Commercial. “There is a real opportunity for specifiers, contractors and installers to provide a best practice service which gets the job right from day one, avoids countless issues, and helps to deliver lifetime system protection – a result that all clients and end‐users want. Best practice water treatment is the way forward for those that want to offer something different, and superior, in a very crowded market.” Performing any of the

steps in the best practice system inadequately will most likely lead to compromised system protection. For example, if a system is dosed with inhibitor but not properly cleaned, the effectiveness of the inhibitor will be hindered, while systems that have been treated but not subsequently maintained may succumb to corrosion if inhibitor levels are diluted to insufficient levels following raw water makeup. Furthermore, poor

quality products, such as such as an inhibitor that doesn’t have the correct pH buffer capacity to completely protect aluminium, may also compromise system protection. System cleaning should be undertaken using a cleaning agent that is specifically designed for the type and age of the system, as well as the form and extent of problem to be treated. Cleaning removes contaminants such as installation debris, flux residue and greases in new systems, and black oxide magnetite and other corrosion debris from older systems. Once a system is clean, protective


measures should be taken in the form of an inhibitor (which is able to protect all system metals) plus a system filter for added insurance. Inhibitor should be dosed to sufficient levels; this can be checked with a water quality and inhibitor test kit. Finally, water treatment should be


maintained. Under ideal conditions, best practice cleaning and inhibitor dosing should be enough to sustain long‐term protection. However, mains water makeup – which can occur due to leaks, remedial works, etc – will lower inhibitor levels and promote corrosion. To ensure a system stays protected, the inhibitor concentration should be checked as part of boiler service visits.

Designed specifically for integration into Building Management Systems or third party controllers, this new concept will hopefully bring an end to the inflexibility associated with being tied into a manufacturer specific system. This also means there is no limit to the number channels (sensors) that can be used.


ollowing the release of a new, aesthetically pleasing sensor housing, Flamefast has just launched a new gas


With a traffic light LCD readout, analogue output, volt free contact and failsafe and latching alarm options, the Flamefast Gas Sensor is the most versatile low cost unit on the market. To support the recent product expansion


and rapid growth of the business, Flamefast is delighted to announce the addition of two new members to our sales team. Our new sales engineers will be providing local support for our products in the North and South West.

eading British manufacturer, Ideal Commercial Boilers is committed to ensuring that every condensing boiler in


its range outperforms current regulations in terms of output, efficiency and energy use. In keeping with this undertaking, the latest addition to its floor standing condensing boiler range, the Imax Xtra EL launched in January 2016, is the only UK boiler to have been awarded a Class 6 NOx rating from the European Standard EN 483: 2000 relating to gas fired central heating boilers. Several have already been installed into the educational, religious and manufacturing market sectors.


NOx (Nitrogen Oxides) are emissions of


highly reactive gases which contain nitrogen and oxygen and are a pollutant contributing to ozone depletion, particulate matter and acid rain, with the main source of NOx emissions being the combustion of fuels in motor vehicles, furnaces and boilers. European Standard EN 483: 2000 awards ratings of one to six to products responsible for NOx emissions, with six being the highest performing NOx class – i.e. the one with the lowest emissions.

T Now open, this interdisciplinary


medical research institute is working to help understand why disease develops and find new ways to prevent and treat illnesses such as cancer, heart disease and stroke, infections, and neurodegenerative diseases. Supporting this development is


a wide range of pumps all of which carry the Grundfos logo. These solutions form an integral part of this precision building application solution and include various Grundfos family members who will help to support the heating,


cooling, water supply, pressure boosting and pressurisation requirements. The Francis Crick Institute is a


consortium of six of the UK's most successful scientific and academic organisations – who invested a total of £700 million to establish the Institute. By 2017, the institute will employ 1,500 staff, including 1,250 scientists, and have an operating budget of over £100 million.
