ADE-7-LOW-resRelcross have employed their problem solving experience by supplying Von Duprin 99QEL exit devices to Advanced Diesel Engineering (ADE) of South Kirkby in Yorkshire. ADE are experts in acoustic containers for generators and their products can be found in an increasing number of data centres throughout Europe. Data Centres have banks of generators on stand-by, ready to come online in seconds in the event of a power failure.  But generators, especially un-containerised diesel generators, are very loud. So loud that they present a substantial problem for anyone nearby and a large number in close proximity would be totally unbearable. A silent generator operates inside a sound proof container or generator enclosure which muffles the sound heard by workers, employees, customers and members of the public.

ADE-15-LOW-resBut like so many problem solving technologies, the solution to the main problem creates other problems to be solved along the way. One of the many that ADE have had to overcome is how to safely and securely open and close the heavily insulated steel doors that provide essential access to the generator and other equipment inside the enclosure. It’s not a problem that most people would anticipate but ordinary door hardware just would not work. The doors are too thick and, apart from access control for security, emergency exit from the enclosure must also be provided in the event of fire or other such eventuality.

Normal entry and exit is controlled by a swipe card system that disengages the door alarms while recording the details of who has entered or exited the container. A key operated lock can then be used to open the door by releasing the latch on the Von Duprin device installed on the inner surface of the door.

ADE-25-LOW-resWhen exit is required the swipe card is used in the same way before the touch bar is used to release the door latch. The Von Duprin 99 QEL features motorised latches rather than magnetic solenoids which, together with the famous Von Duprin fluid dampener that decelerates the touch bar on its return stroke, eliminates most of the noise associated with exit device operations. In the event of an emergency the touch bar can be used independently and without any delay. In such instances the alarm will also sound to alert security. As a further safety feature, the touch bar is covered with a luminous material to provide guidance to people trying to escape from the enclosure if the lighting fails or vision is inhibited by smoke. The Von Duprin 99 QEL, with so many unique features, provides the safe and secure answer in a wide range of demanding installations.

Privacy Door Latch Improves On Traditional Products

The Pemko Privacy Door Latch is a simpler, more effective and easier installed alternative to a security chain or swing bar on a hotel bedroom door.

Pemko PDL 2cMany hotel guests feel much safer when they are away from home with an additional security device on their bedroom door that opens enough to see who is outside – and even examine an ID pass – but stops intruders from opening the door enough to gain access without the occupiers’ consent. Many people have also experienced other guests entering their rooms by mistake, sometimes even issued with the wrong keys at reception.

The commonly used chain or swing bar designs need to be attached to both the door and the frame (and correctly aligned) and both these options can sometimes allow the door to open enough for them to be defeated. In comparison, the Pemko PDL, distributed in the UK by Relcross, has many advantages.
Pemko PDL 1cThe PDL consists of a single bracket with a strong steel flap that can be opened to completely stop the door from opening more than 56mm or closed to allow free access. It is very simple to operate even by those with limited dexterity making it practical for use in rooms adapted for disabled use as well as standard rooms.

It is only attached to the frame leaving the door untouched and pristine. There’s only one bracket to be fixed and no two parts to be aligned. This means it’s easily fitted in just minutes. Fixing to the frame gives a much stronger anchorage and does not rely on a chain or bar secured to a relatively thin and lightweight door. Additionally, it cannot be used to try and keep the door open and so reduces the opportunity for damage to the door and frame by misuse.
PDL (3) tu cropThe Pemko Privacy Door Latch is available in 5 finishes to harmonise with almost any colour scheme making it even more unobtrusive.

Success in the hotel market in the USA has also led to a growing market for the PDL for use on private residential doors, particularly with its easy D-I-Y installation.

Bath University Rely On LCN Door Closers

Bath Uni (11)New buildings at Bath University have relied on a large number of LCN door closers distributed in the UK by Relcross Ltd and supplied to the contractors by IRM of Yate.

The 10 West Building was formally opened in July and provides space for the expansion of the Department of Psychology, a new home for the Institute for Policy Research and a dedicated postgraduate study space on its upper floors.

Bath Uni (7)150 LCN 1261 door closers were installed to doors giving access to corridors, seminar rooms, study rooms and toilets. In fact anywhere that reliable, effective closers were needed. The LCN 1261 is a versatile and economical cast iron closer with dual mounting capability. It is adjustable through spring sizes 1-5 and mounts to the most common commercial footprint. It can also utilise an extensive range of regular and special duty arms such as a hold-open arm, a long arm and an extra duty arm, making it flexible enough to overcome many of the day to day issues associated with the operation of door closers.. It can be mounted on the hinge (Pull Side), top jamb (Push Side) or stop face (Push Side).

Bath Uni (4)It is non-handed for right and left swinging doors and features adjustable hydraulic backcheck to cushion the opening swing prior to 90 degrees. There is separate regulation of the general closing speed and the latching speed. The LCN 1261 carries UK Fire Certification in accordance with BS EN 1634-1:2014 (timber) – 120 mins and is CE Certified.

The durability of the LCN range of closers is based on the forged steel arms and cast iron bodies used. There is no better material for a door closer than cast iron. The manufacturing process may be difficult (which is why just about every other closer manufacturer has turned to aluminium) but the end product lasts for decades. Since internal wear and tear is negligible, even after extreme usage, regular re-adjustment of control valves and spring power is not necessary.

The University of Bath was granted university status in 1966 by Royal Charter, although its roots can be traced back to the Bristol Trade School established in 1856 and renamed the Merchant Venturers’ Technical College in 1885. The University is approaching the halfway point of it’s 2009-2026 Masterplan that includes a number of new academic buildings, residential accommodation and sports facilities as well as other infrastructure and sustainability projects.  The 10 West Building project was finished on time and within the £30m budget by main contractors Vinci Construction and staff have now moved into the building. Other recent projects include the £23m 4 East South Building that has just been handed over to the University by main contractors Bouygues and features a further 89 LCN 1261 door closers. This building provides research and teaching space for the Faculty of Engineering and Design as well as housing a cutting edge computing data centre.

Relcross Sales and Marketing Director Stuart McMaster said “We are delighted to have supplied door closers for Bath University via IRM. The durability and reliability of our LCN closers make them ideal for projects like this and I can confidently predict they will provide many years of trouble free service.

bicolorWith bicolor HEWI offers the option of individual design. Unique fitting solutions become a statement of personal style. Made of two materials, bicolor offers an unusual mix: Polyamide meets stainless steel. Roses made of stainless steel and with metallic finishes in PVD enclose a coloured inlay made of polyamide. Stainless steel and PVD nuances in brass, copper, bronze or black chrome, mirror polished or with sating finish, depending on the lever handle design it is possible to combine with up to 16 polyamide colours. The fitting thus becomes a decorative item on the door and sets completely new accents.

Flat roses not only enable a reduced design, but also fast and easy installation without visible fixings.

Apart from the private premium segment, the option of individualisation is not only interesting for exclusive housing, but also offers companies in office and commercial buildings the option of implementing their corporate design down to the smallest detail. bicolor is available for Systems 111 and 162 from April 2017.

HEWI invites you to a creative play with colour and material on its website www.hewi.com: With the help of a configurator the lever door fittings can be created completely according to personal preferences – whether as a single item or as a continuous design object, which lends the building its own character. Depending on the lever handle design, up to 2500 combinations of the individual components are possible.
