Daikin has upgraded the design of its RZQ Super Inverter (1 phase) and RZQS Comfort Inverter, developed for use in offices, shops and restaurants, thereby increasing efficiencies throughout both ranges. In the case of the RZQS100 for example, cooling and heating efficiencies are improved by up to 23% and 11% respectively over those of the earlier model. Both RZQ and RZQS units continue to support the connection of a wide range of indoor units and retain their wide temperature operating range.

RZQ Super Inverter — high efficiency and installation flexibility

The new RZQ-D Super Inverter currently returns the highest COPs and EERs on the market with energy label 'A' ratings in most configurations and like previous RZQ units, it also has an extended operating range in -15° C to 50° C (cooling) and 15.5&deg C down to -20° C (heating) outdoor ambients.

The unit is flexible with respect to piping diameter and although it utilises R-410A refrigerant, it also allows the re-use of existing R-22 or R-407c field piping with piping lengths up to 75m possible. This ensures easier installation and lower installation costs when upgrading existing buildings. The RZQ is also suitable for technical and computer room cooling.

RZQS Comfort Inverter: improved efficiency

The new RZQS Comfort Inverter also has higher COPs and EERs than previous models, with energy label ratings of 'B' in most configurations. It retains its predecessor's extended operating range – with cooling at outdoor temperatures up to 46° C and heating down to -15° C – and supports multiple indoor units.

Built to last

Both units feature the Daikin emphasis on quality construction with special acrylic pre-coated fins to prevent corrosion on the heat exchanger and resist severe weather conditions. The outdoor units – available in 3,4,5,6 HP models – are fitted with high quality Daikin swing or scroll compressors, renowned for their low noise, high energy efficiency and trouble-free operation.

Megger’s latest MFT1553 multifunction tester, which brings Bluetooth wireless connectivity to one of the UK’s most popular and successful ranges of test instruments for electrical contractors, has achieved the outstanding accolade of winning all three major industry awards for excellence and technical innovation in a period of just eight weeks.

Megger collected the first award for its groundbreaking MFT1553 from the Association of Electrical Contractors of Ireland, where it was recognised as the AECI Product of the Year. This was swiftly followed by success at the Electrical Industry Awards held in London, where the MFT1553 was the winner in the Test and Measurement category.

Finally, in the last major awards event of the year, held under the auspices of SELECT, Scotland’s trade association for the electrical, electronics and communication systems industries, the MFT1553 was again successful in winning the Best New Product category.

In each of the three awards, the judges were impressed by the Bluetooth capabilities of the MFT1553 multi-function tester, which make it fast and easy to transmit test results directly in to an electrical test certificate on a PC or held-held devices such as a PDA or even a smart-mobile phone without the need for inconvenient wired connections.

Safety was held to be another important benefit as, with no electrical connection between the instrument and the computer or mobile device, complete isolation is guaranteed. In addition, the judges at the Electrical Industry Award commented that they believed the MFT1553 to be by far the most innovative product in its category.

“We’re absolutely delighted to have won these three awards,” said Megger’s Julian Grant. “This is an unprecedented achievement that not only rewards all of the hard work that the Megger team has put into developing the MFT range, but also confirms the success of our policy of listening to our customers and producing products that genuinely meet their needs.”

“Our MFT range has achieved outstanding sales success ever since it was launched three years ago,” he continued. “We believe – and the award judges clearly agree – that the addition of Bluetooth support will ensure that it continues to go from strength to strength.”

Vaisala introduces a new version of the weather transmitter, the Vaisala Weather Transmitter WXT520. The WXT520 measures wind speed and direction, liquid precipitation, barometric pressure, temperature and relative humidity – all in one instrument.

The wind speed and direction measurement is based on the ultrasonic Vaisala WINDCAP® Sensor, which ensures accurate readings from any horizontal wind direction without blind angles and corrupted readings. Barometric pressure, temperature, and humidity measurements are combined in one separate module using capacitive measurement for each parameter. The module can be changed without any contact with the internal sensors.

The precipitation measurement in the WXT520 is unique as it measures accumulated rainfall, rain intensity and duration, all in real time. It is based on the maintenance-free Vaisala RAINCAP® sensor that gives more detailed information on precipitation compared to traditional precipitation gauges.

The WXT520 housing with the mounting kit is water resistant and classified as IP66. The transmitter has a new interface card that fulfills the more demanding EMC/ESD requirements in the Marine IEC60945 standard. The WXT520 complies with the EMC standard EN61326-1; Industrial Environment. The transmitter is ROHS compliant.

A number of optional features are offered for the WXT520, for example, heating, a bird spike kit, a USB connection, and a new surge protector. The wind and rain sensors can be equipped with heating to improve the availability of correct measurement data also in severe weather conditions. The bird spike kit helps to deter birds from the WXT520. The USB connection facilitates the connection to a PC as a service connector, or when the PC is used as a terminal device. The Vaisala Surge Protector WSP152 is designed to protect the host PC against surges that may be entering through the USB port.

The power consumption of the WXT520 is very low; it can use solar panels as an energy source.

The WXT520 is suitable for weather stations, dense networks, buildings, golf courses, marinas, harbors, and hotels – almost anywhere where real time weather data is needed.

Rockwool, the world’s leading manufacturer of non-combustible stone wool insulation solutions, has won the contract to supply around £600,000 of insulation materials for BSkyB’s new state-of-the-art building project near Heathrow in West London, which it is set to be Europe’s most sustainable broadcast facility for Sky Sports and Sky’s entertainment channels.

The insulation project is expected to be completed by the end of 2009, with the whole 23,000 sq/m, £233m centre due to be completed in 2011. BSkyB is the UK’s largest subscription and pay-TV provider, with more than nine million subscribers in the UK and Ireland.

Rockwool’s insulation material will be used to insulate all the mechanical services such as pipework and ductwork within the building. Rockwool’s insulation material has thermal properties which are important in fulfilling BSkyB’s green aims for its new headquarters. The insulation is comprised of an open fibrous structure, which makes it ideal for absorbing and regulating noise, which is crucial in a broadcasting environment.

Andy Halsall, Director of UK Sales at Rockwool, said: “BSkyB has made it clear it wants to have the greenest headquarters possible and Rockwool’s insulation materials will be important in achieving that. Increasingly major corporations recognise that they need to develop sustainable buildings in order to limit their structures’ Ozone Depleting Potential (ODP) and Global Warming Potential (GWP).”

Ron Turner from Abbey Thermal, the thermal insulation contractor, said: “We selected Rockwool after completing an exacting tendering process. It was the only product that met our rigorous standards for acoustic and thermal performance while offering the highest levels of passive fire protection. The insulation meets all our criteria for sustainability, not only is it manufactured to very high ‘green’ standards, it can be recycled when the building comes to the end of its life cycle reducing the pressure on landfill.”

Building Services Consultants, Pick Everard, recently completed the design of all the lighting for a major Education PFI project for five new schools in Derby. The projects were Sinfin Primary School, Hardwick Primary School, Lakeside Community Primary School, Merrill College and Da Vinci Community College.

A large proportion of luminaires, with a value of about £380,000, were supplied by Concord. Lighting designer Carl Ackers, of Pick Everard, comments: ‘One of the main reasons Concord was specified was because we considered them as a quality manufacturer, offering an excellent product and service proposition at a cost-competitive price’.

The lighting scheme had to meet the main objective of the lighting design for the new educational facilities. The design had to create a bright, vibrant and visionary learning environment for all areas within the schools. The schemes also had to be highly energy efficient, so all the lighting is controlled by an automated lighting control system, with both photocells and occupancy sensors, to maximise daylight use and to dim and switch off luminaires when not required.

The main Concord luminaires used on the Derby project were:

• The Ovation 65 system was used wherever suspended lighting was required in areas without a dropped ceiling. Ovation proved to be a flexible system for these applications and enabled fully automatic dimming, daylight linking and presence detection. The Ovation system could also be installed in continuous lengths, with flexible length ‘dummy’ sections, where required.
• The LED 100TE luminaire was specified as a highly effective downlight solution within the corridors, due to its small size, low recess depth and cost-effectiveness – an important consideration in all the circulation spaces.
• Lumiance Pento pendants were used in the double-height circulation spaces and some of the dining halls, using various lamp wattages from 1x32W to 4x32W, to maintain a common design theme.
• In most teaching spaces with dropped ceilings, the Equilibro range of fittings was the chosen solution. Again, all luminaires are dimmable and connected to the automatic lighting control system.
• In more utilitarian areas, such as storage and service rooms, Sylpack and Sylproof Pro fittings were employed.
• The circulation spaces and play areas around the exterior of the schools needed lighting too, for both safety and visual comfort – here the Monitor wall light played an excellent role, due to its powerful 70W CDM-TT lumen package and high IK10 impact rating.
• In one location there was a special need to bridge a gap in the ceiling created by a light well. Concord’s Channel system was employed to great effect, due to its slim, unobtrusive profile, which didn’t obstruct the view.

Every now and then the security industry throws out a story with a jaw dropping wow factor, keep reading because this story is it for 2009.

Granted, reading it here won’t be the same as when you witness the video footage, but when you do, remember you read it here first.

You know those crash tests we all stop and watch at IFSEC and other shows, the footage of trucks crashing into security bollards designed to stop terrorist attack? Well if you are at IFSEC this year make a point of taking a walk over to Stand C40 where ATG Access will be showing their latest and most spectacular crash test. Even if you are not at IFSEC then take a look at the video because if you are interested in physical security then you are going to want to see this.

One single ATG Access SP1200 Automatic Rising Bollard has stopped a fully laden 30 tonne truck travelling at 50mph, yes that was 30 tonne at 50mph. There is nothing to compare this test to, a testing site representative who witnessed the test said “at this time this is the highest energy level ever tested to in the world, this product has performed to a level which surpasses our own original specifications.”

When the truck struck the bollard the energy produced was around 7400 kJ just for illustration this is roughly equivalent to the energy of a 1.5 tonne car travelling at over 220mph.

Words are sometimes not enough to illustrate a point, just take a look.
