As in any joint enterprise, a rapport of trust is essential to achieve success. Over the years, Dextra Group has worked hard to build this trust with contractors, consultants and end-users alike, going the extra mile in all departments from design to delivery.
Having won a renovation contract for Compass South offices in Chatham, Polar Air building services placed its confidence in Dextra Lighting as a result of showing an edge in manufacturing lead times, a highly competent in-house design team offering full CAD/CAM support and payback calculations, fast and responsive delivery, a comprehensive and highly customisable range of high-quality, energy-efficient products and numerous industry awards.
As with most refits, the objective was to inject as much value into the office space as possible. The lighting design would therefore need to meet high standards of quality, adhere to all the relevant compliance criteria, and find ways to minimise the total cost of ownership of the new system 법령안편집기 다운로드. The result would be an attractive and sustainable office environment, lowering energy and maintenance costs for the future at no premium. High-efficiency, sensor-controlled LED luminaires combined with effective measures to reduce installation times and costs, were crucial means to achieve this goal.
It must also be stressed, that today’s clientele in all sectors, expect buildings to be future-proofed in terms of environmental and financial sustainability, making LED lighting, combined with intelligent sensors and dimming controls, a key aspect of refurbishment or design and build projects. This is why Dexsor – Dextra Group’s dedicated electronic controls subsidiary, was founded; incorporating the highest quality bespoke lighting control systems within each installation to maximise their energy-saving potential gta4 한글 다운로드.
As Dextra Group’s luminaires are manufactured using the latest Lumileds LEDs offering 90% lumen maintenance for the first 60,000 operating hours and high-quality and reliable drivers from leading European manufacturers, each lighting scheme is capable of generating energy savings of up to 70% compared to fluorescent or HID alternatives. Once installed, maintenance becomes a hassle-free affair as luminaires will perform as required for longer by eliminating the common issues of conventional light sources, such as frequent lamp failures and fast depreciation of brightness over time.
The lighting design was to cover two entire floors featuring open plan offices, canteen and breakout areas, a reception, lobby and amenities. Compliance to Lighting Guide 3 and CIBSE (Chartered Institute of Building Services) guidelines for office environments was required; ensuring staff would enjoy a comfortable, safe and stimulating workplace Non-Muhui. Products selected for the project would also be listed in the Energy Technology List to ensure the system would abide to the latest energy-efficiency criteria and generate further savings through the ECA compliant scheme, which offers a 100% tax levy on the investment upon purchase. Emergency lighting was to be provided in all areas in accordance with the relevant building regulations.

Dexsor – Modular Wiring Systems
To further reduce energy costs and carbon emissions as well as provide additional lighting control, the luminaire is made compatible with a choice of analogue or digital dimming functions and standalone sensors from Dexsor’s Reacta range.
By introducing Dexsor’s Modular Wiring System, complete with Fast-Fix luminaire connectors, rapid-install interconnecting cables and programmable marshalling boxes, Polar Air was able to make significant savings for the end-client by reducing the overall fitting times, with the added convenience of having both the luminaires and customised sensor and dimming controls supplied by the same manufacturer.
Sets of 6 to 9 luminaires were installed above each group of desks to provide uniform illumination for each member of staff. Each set is now controlled by a single lighting control module (LCM) connected to a Reacta 7 microwave occupancy sensor 타이타닉 한글 다운로드. By keeping the number of sensors and control units as low as possible without compromising the precision of the sensor’s detection area and functionality, installation times were further reduced, making sure that the project did not overrun and delivered cost-effectively.
The Reacta 7 sensor and LCMs now allow each luminaire to switch off when members of staff have vacated the area or when daylight reaches an adequate level, thereby accumulating energy savings throughout the day and improving returns on investment. Detection settings can now be programmed using a user-friendly 17 button infrared hand held tool.
Protec LED – Reception, Lobby & WC Facilities
Cutting-edge optic design and premium components make the Protec LED a high-performance and attractive choice for a host of applications old version mac os.
Versions of the ultra-versatile Protec LED were adapted for various areas of the building. With a wide range of customisable options including a number of lumen outputs, reflectors (specular and semi-specular), colour attachments and custom bezels, designers have increased flexibility to create the ideal scheme for a different applications.
Interchangeable reflectors and colour attachments can be supplied to make the luminaire adaptable to future changes in décor and layout. Different colour temperatures and CRI (colour rendering) options are available to ensure that the optimal light quality is achieved with each application. Microprism, semi-specular diffuser also allow this range to include BSEN 12464 glare compliant versions, offering a diffused, low-glare light quality ideal for office use Trot free download.
The Protec LED has long established itself as the downlight of choice across a number of sectors spanning from retail to industrial.
