Vent‐Axia supports local youth charity


rawley‐based Vent‐Axia, the UK’s leading ventilation company, presented a cheque to The Worshipful, the Mayor of Crawley, Councillor Raj Sharma on Tuesday 9th May to support the Mayor’s charity for 2016/17, Crawley Community Youth Service. The cheque was presented by Jenny Smith, Marketing Manager of Vent‐Axia in the Mayor's parlour in Town Hall, The Boulevard, Crawley, West Sussex RH10 1UZ. Vent‐Axia chose to support Crawley Community


Youth Service as its charity for its 80th anniversary year, 2016. To raise funds for this local charity, the company held a Christmas raffle, netting over £300 for the Service. Crawley Community Youth Service aims to encourage young people to be positive role models who can create engaged vibrant and equal communities throughout Crawley. It provides clubs for young people in Bewbush, Gossops Green and Langley Green. “Vent‐Axia is delighted to support Crawley Community Youth Service and help local young people,” said Jenny Smith, Marketing Manager of Vent‐Axia. “We were keen to support our local community when we picked our charity for the year and the Service is a great example of bringing the community together and empowering young people. We are delighted to be able to work alongside the Mayor in supporting their work.”

he next generation of pressure independent control systems has been announced by Advanced Air. They have entered into a special agreement with Belimo and Advanced Air’s control specialist to design and develop an amazingly simple EPIV/Delta control package. The EPIV/Delta means that


T


the fan coil unit can be pre‐ commissioned in the factory with the set points for both water and airflow established and pre‐set so there is no need for any on site commissioning. The unit is fully


addressable from a hand held device where the unit can be easily checked to ascertain that the pre‐set values are being achieved even without the BMS working. The LED screen on the hand held device shows the engineer exactly what is happening with the fan coil unit. If changes to the fan coil performance are required due to design changes then the set points can easily be adjusted by the hand held device. All of this information is communicated to the BMS when it is fully operational. This simple single point complete


controls package means that everything is being supplied and fitted by the fan coil manufacturer.


Comparing the Electronic Pressure Independent Valve (EPIV/Delta) control system to the current Pressure Independent Control Valve (PICV) means there are no strainers, no binder test points, no complicated pipework, no commissioning.


Lighting Controls eliminates commissioning on CAT A installations


lighting control network to be checked before commissioning. In other words, the integrity of the installation can be checked when the network wiring is completed, and the lighting system fully working. All DALI strings are also tested. With this new and innovative protocol the building lighting is functional before a CAT B fit out but without commissioning costs. The area controller has four

buttons: Two to check that the lamps dim and brighten; one button to start the Test function; and, one button to cancel the Test function. Pushing the Test button causes the

There are further benefits of creating pressure independence electronically compared to using PICV which can require 10‐20kpa. The EPIV does not need this pressure to operate it as everything is achieved electronically. Consequently there is a potential energy saving with lower pressure and smaller pumps. Andrew Sargent, Advanced Air’s General


Manager, said that the EPIV/Delta would revolutionise the fan coil market because the control system has single point responsibility, i.e. the fan coil manufacturer, and offers huge benefits to the designer and installer.

lights to go OFF either for 20 minutes or until the Cancel button is pushed. After installation of the new area


controller and other components using the new protocol, all lights connected to the area controller are ON when activated by any PIR in the system. All luminaires remain ON until 30 minutes after any PIR has ceased to sense motion. The development of this new


protocol is the latest in a line of new products that reduces installation and maintenance costs while maximising reliability and flexibility. For more information about this and our latest new products visit:

Ground‐breaking ventilation technology is hitting new heights with its latest derivative…


ilberts Blackpool, the UK’s leading air movement specialist, believes it was the


first manufacturer in its field to develop a hybrid system that utilises internal heat to warm incoming air through wall façade louvres without using a heat exchanger. Now a new version of the pioneering Mistrale Fusion System (MFS) has taken the same concept from façade to roof, with MFS‐V (Vertical). MFS‐V incorporates two Fusion


MFS128 units placed vertically into a rooftop penthouse turret, with a shaft up to 1500mm2 ensuring effective ‘stand‐alone’ ventilation of the space below. No additional ducting or plant is required. By routing the ventilation through the roof then internal spaces that have no external façade can still be efficiently ventilated, be it via natural or hybrid principles. The concept has already been


put into practice, at eight schools being built in the Midlands which feature enclosed single storey sunken garden ‘break out’ spaces over classrooms surrounded by a two‐storey building: the single

most probable number method for the enumeration of Legionella pneumophila from potable and related water samples,” by leading water microbiology consultant, David Sartory, in Letters in Applied Microbiology. The paper concludes that the IDEXX Legiolert™/Quanti‐Tray® test is superior to the standard method for quantifying Legionella pneumophila (L. pneumophila), the primary cause of Legionnaires’ disease. The study compared


performance of the IDEXX Legiolert/Quanti‐Tray most probable number (MPN) method, with the ISO 11731‐2 membrane filtration method for the enumeration of L. pneumophila from 100 ml potable water and related samples. Data from a multi‐laboratory study analysed

according to ISO 17994 showed that Legiolert/Quanti‐Tray yielded on average higher counts of L. pneumophila. It also quantified the Legiolert medium as having a high specificity of 96·4%, and concluded that Legiolert/Quanti‐ Tray represented a significant improvement in the enumeration of L. pneumophila from drinking water‐related samples. The IDEXX Legiolert test is based on a bacterial enzyme detection technology that signals the presence of L. pneumophila through utilisation of a substrate present in the Legiolert reagent. L. pneumophila cells grow rapidly and reproduce using the rich supply of nutrients present in the Legiolert reagent. Actively growing strains of L. pneumophila use the added substrate to produce a brown colour indicator. Legiolert detects L. pneumophila at 1 organism in a 100 ml sample within 7 days.
