Story

The feature-packed MEM Memera Consumer Unit range has been redesigned and expanded. It now includes units developed specifically to overcome problems faced by installers endeavouring to meet the requirements of the 17th Edition of the IEE Wiring Regulations (BS 7671), in particular the need for more wiring space when units are fitted with RCBO protection of individual outgoing circuits.

Features of the new range include:-

* A new 11-way unit designed specifically for RCBO protection of outgoing ways
* Moulded and metal enclosures with up to 19 and 38 outgoing ways respectively
* New 1-way and 2/3-way consumer units
* A new 80A + 63A dual-RCD option
* Type B or Type C MCBs and RCBOs
* An option for protective and control devices to be factory-fitted

Electrical contractors have found that conventional consumer units do not allow enough space for wiring when RCBOs are fitted instead of MCBs to protect individual outgoing circuits. The range now includes an 11-way consumer unit designed specifically to take RCBOs and yet allow generous space for wiring above the devices. Individual RCBOs offer the highest possible level of personal protection demanded by BS 7671.

Other advanced features that have long distinguished the Memera 2000AD units are retained. These include the unique snappable busbar that allows on-site configuration of split-load units, a removable pan assembly that simplifies installation, and extremely flexible cut-out provision for cable entry in the rear of the moulded units.

The new units offer DP isolator or RCD incoming main switch options. Versions are available to satisfy the many configurations required to enable an installer to comply with the personal protection requirements of the 17th Edition of the IEE Wiring Regulations.

They include isolator-controlled single and dual RCD units, dual RCD variable split-load boards and the new 11-way RCBO board. In addition to the existing dual RCD split-load arrangement with two 80A RCDs, there is a cost-effective alternative with one 80A RCD and one 63A RCD. At the smaller end of the range are new one-way and 2/3-way units suitable for extensions and additions to existing installations, garages and outbuildings.

The moulded units are available with up to 19 outgoing ways, as with the existing Memera range, to cope with modern requirements for more circuits and/or special control and command devices. If more ways are required, two units can be linked together by means of AD coupling kits. Metal consumer units are available for surface or flush mounting and include dual-rail units offering up to 38 outgoing ways, as well as multiple RCD split-load units and dual/multi tariff arrangements.

The new range of outgoing devices includes single-module miniature circuit-breakers (MCBs) up to 63A and single-module RCBOs (combined MCBs and RCDs) up to 45A. In addition to the standard Type B devices, Type C MCBs and RCBOs are also available for applications involving high inrush currents, such as some lighting loads, which are prone to cause nuisance tripping with some Type B devices. The offering also includes a full range of control and command accessories including timers, relays and contactors.

The new MEM Memera consumer unit range supersedes the Memera 2000 and 2000AD ranges. Devices will continue to be available to fit these units for the foreseeable future.

Building 85 lies within the campus of Southampton University, and is the new home for the Institute of Life Sciences. This new, state of the art building cost in the region of £34 million to construct, and core to the design was the use of sustainable and low maintenance materials, a category which included fire glazing systems from Fendor.

Over 40 different fire glazing elements were required for the interior of the building, ranging from screens, doors and panels offering 30 minutes fire rating in the atrium to 60 minute fire rated doors and screens in the lift lobby. Architects NBBJ of London were responsible for the design and according to project architect, Crysta Falcon, the Fendor Fireline system was the best option in terms of performance, appearance and sustainability.

“We chose the Fireline system because of its proven ability to offer the required fire rating, and due to its fire performance without having to compromise aesthetics in the ten metre atrium, ” she commented. “The whole theme of the building raises the bar in terms of design sustainability, with timber featuring heavily both internally and externally.

The cladding is Western Red Cedar and the internal panelling is bamboo. The door and joinery features are also timber and the steel Fireline system was the ideal complement to the wood detailing. Polyester powder coated finished, the fire glazed elements offer very low maintenance, significantly reducing the need for repainting and redecoration.”

The Fireline range of fire resistant glazing meets all legislative and safety requirements for fire integrity and fire insulation, and offers natural light into buildings whilst still performing its primary function. This enables it to be used as a design medium in its own right, as is the case at Building 85 where the glazing complements the rest of the interior design.

The seven story high Institute of Life Science was opened earlier this year, and students at the university now have a new location for their studies, a building that is modern, contemporary and meets all regulations for fire safety and security.

• Rotary switch selects one of five test modes, including auto start on connection, giving ease of use

Tough work horse
Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger´s new heavy duty DLRO10HD low resistance ohmmeter combines rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat. Like all models in the DLRO10 range, the DLRO10HD, when used with optional terminal insulating test leads, is rated CATIII, 300 V in line with IEC61010.

This versatile new test set is built into a tough but easy–to–carry case that provides an IP65 ingress protection rating when closed and an IP54 rating when the instrument is in use and operating from battery power.

Easy to use with gloved hand
The instrument´s rotary switch controls are convenient to operate even with gloved hands, and it incorporates a large backlit liquid crystal display that can be easily read from a considerable distance.

With 0.1 µO resolution, 0.2% basic accuracy, and a dedicated mode for use with inductive loads, the DLRO10HD is ideal for applications as diverse as checking the integrity of welded joints and verifying winding resistance in large motors and transformers.

To provide maximum versatility, this innovative test set not only features high compliance but also offers user–selectable high or low power ranges. The high power < 25 W ranges (measuring up to 250 mO at 10 A , or 2.5 O at 1 A) are ideal for heating a weakness or charging inductive loads. The low power ranges are power limited to 250 mW for applications where it is desirable to avoid heating the item under test.

Choice of test modes
The instrument offers a choice of five test modes. In normal mode, the test is initiated by pressing the “test” button. The instrument verifies continuity of all four connections, and then applies the test current in both forward and reverse directions before displaying the result. In automatic mode, the test starts as soon as the probes make contact with the item under test.

Automatic unidirectional mode is the same as automatic mode, but the test current is applied in one direction only. This reduces the testing time, but thermal EMFs from contact between dissimilar metals may reduce the accuracy of the results.

Continuous mode makes repeated measurements at three–second intervals on the same sample. Inductive mode is, as the name suggests, optimised for tests on motors, transformers and other inductive loads, supplying a full 10 Amps for 60 up to seconds.

DLRO10HD heavy–duty low resistance ohmmeters from Megger are supplied, as standard, with a set of test leads fitted with high–quality duplex hand spikes featuring lights to remotely indicate when a test is complete or inadvertent connection to live supply. Test leads with Kelvin clips are also available as an option.

The next generation of Hep₂O is about to hit the market – providing professional installers with a technologically advanced range of white push-fit fittings which give unparalleled security for any plumbing job.

Following several years of research with professional plumbers which highlighted the key issues they face, the revolutionary new range features a hidden advantage – a unique and patented system called In4Sure™ joint recognition technology. This means the installer now knows for certain when the pipe is fully inserted. The profiled end of the re-designed SmartSleeve™ interacts with the castellations inside the Hep2O fitting – enabling the user to simply push the pipe in, twist and feel the ‘rumble’ to make a fully secure connection.

Another design feature of the next generation Hep₂O range is the ease with which pipes can be released. The new demounting system uses a HepKey™ to make releasing quicker and easier. There are two types of HepKey™ available – the HepKey Plus™ clips onto the fitting, depresses the inner sleeve and holds the grab ring open while the smaller pocket size HepKey™ clips around the pipe to release the system with minimum effort. HeyKeys™ will be included in all pipe coils and packs of popular fittings to ensure the installer always has one to hand.

“Next generation Hep₂O meets the criteria set out by installers during our research and development phase,” explains Gareth Samuel, Product Manager. “During our research, installers told us that if there was a way they could easily tell that a secure joint has been made, it would be a real benefit. We wanted to develop a system that would give installers total confidence, and we believe next generation Hep2O offers this and much more.

“In4Sure™ is the hidden advantage. It’s been designed so installers have no doubt when the pipe has been inserted correctly. The system allows installers to actually feel when the joint has been made so that on busy and often noisy sites, fitting the product is intuitive. It’s very simple to use but ingenious at the same time. The clever HepKey™ demounting system helps to prevent any accidental release or tampering with the system, giving further peace of mind.

“We also received feedback from plumbers that a slimmer, white range would be more attractive in areas that are highly visible. By listening to what they wanted and providing solutions to their common problems, we feel confident installers will see next generation Hep₂O as a major step forward in plumbing. Our confidence in the product is further illustrated by our industry leading 50-year guarantee.”

In terms of security a product has to be tested to virtual destruction to determine whether it truly performs. Even so, the ultimate proof is a real life situation and in the case of FAKRO’s topSafe® system the results of an attempted burglary speak for themselves.** 3 FTP-V windows in conservation style were targeted because views of the roof were obscured from the ground. The burglars were doubtless aware of the ease with which many well known roof windows can be opened but attempts in this case met with total failure despite the evident use of a crowbar. Though the damage was clearly significant, repair was possible as FAKRO’s windows are all designed to be broken down for ultimate recycling.

The patented, topSafe® system is not used by any other manufacturer and provides the highest standard of security and safety currently available as standard (Class 3 – EN 13049). It employs a combination of additional steel reinforcement built into the lower part of the sash, improved lock security and longer screws driven in at an angle to prevent hinges being ruptured. U.K. Sales Director Phil Adams commented, “topSafe enables the window sash to withstand even the weight of an individual jumping on it. As a result, a number of FAKRO windows achieve EN13049 Class 4 when many competitors’ products barely meet basic standards of lock security”.

U1000 – Permanent/fixed clamp-on flow metering solution

Sub-metering of hot and chilled water services to monitor, control and manage water and energy consumption is an area of growing demand in building services and energy management. But the installation process including system drain down, pipe cutting etc has always been a significant cost and barrier to wider application of sub-metering. At last a solution from the longest established manufacturer of clamp-on, ultrasonic meters has arrived, the U1000 from Micronics. Building on their many years of experience and success in this area, Micronics has now developed a cost-engineered, factory configured water flow measurement solution to facilitate the wider use of water sub-metering and flow measurement for energy monitoring.

The U1000 is a simple out of the box, onto the pipe meter or flow measurement solution with no programming or specialist engineering required! Simply tell Micronics your pipe size and they will send you a factory configured meter, ready to clamp-on and produce flow information in minutes. All you have to do is clamp the unit to the pipe, release the sensor clamps, connect power and enter the pipe size. Yes it really is that simple because Micronics have listened and simple installation is a key design feature. Another cost-effective alternative to expensive in-line meter installation from Micronics, plus dry servicing, providing minimum downtime and maximum availability!

The U1000 is a transit time ultrasonic flow meter designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!

So if you need a stand-alone water meter or sub-metering of hot and chilled water services as part of your aM&T or BEM’s system the U1000 should be a must consider solution.
